Session and Tracks

• Advanced Biofuels

As the global demand for clean energy grows, advanced biofuels have emerged as a promising alternative to fossil fuels. Unlike first-generation biofuels, which rely on food crops such as corn and sugarcane, advanced biofuels are produced from non-food biomass, including agricultural residues, algae, municipal waste, and lignocellulosic materials. These biofuels offer higher energy efficiency, lower carbon emissions, and greater sustainability, making them a key component in the transition to a low-carbon economy. Derived from wood, grasses, and crop residues, these biofuels undergo biochemical (fermentation) or thermochemical (gasification, pyrolysis) conversion. Algae produce high lipid content, which can be converted into biodiesel, biogasoline, and aviation fuels. These advanced fuels, such as renewable diesel and Fischer-Tropsch biofuels, are designed to replace conventional fuels without engine modifications. Despite their potential, advanced biofuels face challenges such as high production costs, feedstock availability, and scalability issues. However, innovations in synthetic biology, carbon capture, and hybrid conversion technologies are driving progress. With continued research, policy support, and investment, advanced biofuels will play a vital role in shaping the future of sustainable energy. Lower Carbon Footprint Reduce greenhouse gas emissions by up to 90% compared to fossil fuels. Utilization of Waste Biomass Converts agricultural residues, municipal waste, and CO? into energy. High Energy Yield Lignocellulosic biomass and algae provide superior energy efficiency.

• Algae Biofuels

As the demand for sustainable and low-carbon energy sources grows, algae biofuels have gained significant attention as a next-generation alternative to fossil fuels. Algae-based biofuels are derived from microalgae and macroalgae that can efficiently convert sunlight, carbon dioxide, and nutrients into biomass rich in lipids, carbohydrates, and proteins. These components can be further processed into various biofuels, including biodiesel, bioethanol, biogasoline, and jet fuel. Algae have a much higher growth rate and biomass productivity compared to terrestrial crops. Certain microalgae species can double their biomass in a few hours to a few days, making them a highly efficient feedstock for biofuel production. Unlike first-generation biofuels, which rely on food-based feedstocks like corn and sugarcane, algae can grow in non-arable land, wastewater, or saltwater, reducing competition with food production. Many algae species have high oil content (20–50%), making them ideal for biodiesel production through transesterification. This biodiesel can be used in existing diesel engines with minimal modifications. Algae biofuels hold immense potential to become a mainstream renewable energy source. Advances in synthetic biology, carbon capture integration, and AI-driven algae cultivation are making the process more viable. Governments and private companies are investing in commercial-scale algae biofuel projects to improve cost-effectiveness.

• Cellulosic Ethanol

Cellulosic ethanol is a second-generation biofuel produced from lignocellulosic biomass, including agricultural residues (corn stover, wheat straw), forestry waste, energy crops (switchgrass, miscanthus), and municipal solid waste. Unlike traditional ethanol derived from starch-based feedstocks such as corn and sugarcane, cellulosic ethanol is sourced from non-food plant materials, making it a more sustainable and eco-friendly alternative. Cellulosic ethanol offers up to 90% lower greenhouse gas (GHG) emissions compared to gasoline, significantly reducing the environmental impact of transportation fuels. Since it is produced from agricultural and forestry residues, cellulosic ethanol does not compete with food production, addressing the food vs. fuel debate. Lignocellulosic biomass is widely available and underutilized, with an estimated 1.5 billion tons of biomass produced annually in the U.S. alone, providing a steady and sustainable supply for ethanol production. The lignocellulosic structure is broken down using chemical, thermal, or mechanical treatments to expose the cellulose and hemicellulose for further processing. Specialized enzymes (cellulases and hemicellulases) break down cellulose and hemicellulose into simple sugars (glucose, xylose). Cellulosic ethanol is gaining traction due to advancements in enzyme technology, synthetic biology, and biorefinery integration. Companies and governments are investing in commercial-scale cellulosic ethanol plants to improve cost competitiveness and scalability.With continued research, policy incentives, and infrastructure development, cellulosic ethanol has the potential to play a vital role in decarbonizing transportation, enhancing energy security, and reducing reliance on fossil fuels.

• Thermochemical Conversion

Thermochemical conversion is a process that utilizes heat and chemical reactions to convert biomass into biofuels, chemicals, and energy. Unlike biochemical conversion, which relies on microorganisms and enzymes, thermochemical methods break down biomass at high temperatures into valuable energy products, making it a fast and efficient approach for biofuel production.Thermochemical conversion is particularly advantageous for lignocellulosic biomass, agricultural residues, forestry waste, and municipal solid waste, as it can process complex and heterogeneous feedstocks with minimal preprocessing. The main thermochemical pathways include combustion, pyrolysis, gasification, and hydrothermal liquefaction (HTL), each offering distinct bioenergy outputs. Thermochemical conversion is a promising pathway for large-scale biofuel production, particularly for aviation, marine, and heavy transport sectors that require high-energy-density fuels. Emerging technologies such as plasma gasification, supercritical water gasification, and AI-driven process optimization are further enhancing efficiency and commercial viability.With continuous advancements in reactor technologies, feedstock supply chains, and policy incentives, thermochemical biofuels can play a crucial role in decarbonizing energy systems and achieving global sustainability goals. Biomass is treated with hot compressed water (250–400°C, high pressure) to produce bio-crude oil. Biomass is exposed to high temperatures (800–1,200°C) with limited oxygen or steam, converting it into syngas (a mixture of CO, H?, and CH?).Biomass is heated at 400–600°C in the absence of oxygen, breaking it down into bio-oil, syngas, and biochar.

• Biochemical Conversion

Biochemical conversion is a process that uses microorganisms and enzymes to break down biomass into biofuels, biogas, and value-added biochemicals. This process primarily involves fermentation and anaerobic digestion, making it a key technology in second-generation biofuels and waste-to-energy solutions. Unlike thermochemical methods, which rely on high temperatures, biochemical conversion operates under mild conditions, making it more energy-efficient and environmentally friendly.Biochemical conversion is particularly effective for sugar- and starch-based biomass (corn, sugarcane, potatoes), lignocellulosic feedstocks (wood, agricultural residues, grasses), and organic waste materials (food waste, manure, wastewater sludge). Microorganisms such as yeast and bacteria convert sugars into bioethanol or biobutanol under anaerobic conditions. Organic matter is broken down by anaerobic bacteria in oxygen-free environments, producing biogas (methane, CO?) and digestate. Biogas is used in combined heat and power (CHP) plants, upgraded into biomethane for injection into natural gas grids, or converted into compressed natural gas (CNG) for transport. Lignocellulosic biomass (e.g., wood, crop residues) is pretreated and hydrolyzed using enzymes (cellulases, hemicellulases) to release fermentable sugars. Advancements in synthetic biology, genetic engineering, and enzyme technology are making biochemical conversion more efficient and cost-competitive. New microbial strains with higher tolerance and productivity, coupled with AI-driven bioprocess optimization, are enhancing biofuel yields and process economics.With increasing policy support, research investments, and the shift toward circular bioeconomy models, biochemical conversion will play a vital role in reducing fossil fuel dependence, managing organic waste, and promoting sustainable energy production.

• Biohydrogen Production

Biohydrogen production is a promising and sustainable method for generating clean, renewable hydrogen using biological processes. Hydrogen is considered an ideal alternative fuel due to its high energy content and its ability to produce only water as a byproduct when used in fuel cells. Unlike conventional hydrogen production methods that rely on fossil fuels, biohydrogen is generated from organic biomass, wastewater, and microorganisms, making it an eco-friendly solution for future energy needs. Anaerobic bacteria break down organic materials (e.g., glucose, agricultural waste, wastewater) in the absence of oxygen, producing hydrogen and organic acids. Photosynthetic bacteria use light energy to convert organic acids into hydrogen. Uses electrically active bacteria to break down organic matter and produce hydrogen in a low-voltage electrochemical system. Algae perform oxygenic photosynthesis, splitting water into hydrogen and oxygen using sunlight. With advancements in synthetic biology, metabolic engineering, and bioprocess optimization, biohydrogen production is becoming more efficient and economically feasible. New approaches, such as hybrid systems combining dark fermentation with microbial electrolysis cells (MECs) and engineered algae with enhanced hydrogenase activity, offer higher yields and lower costs.As governments push for clean energy transitions, biohydrogen will play a crucial role in decarbonizing industries, transportation, and power generation, supporting a sustainable hydrogen economy.

• Synthetic Biology for Biofuels

Synthetic biology is an emerging field that applies engineering principles to biology, enabling the design and modification of organisms for specific purposes. In the context of biofuels, synthetic biology is revolutionizing the way bio-based energy is produced by enhancing metabolic pathways, optimizing microbial strains, and creating novel biological systems. These advancements are driving higher yields, improved efficiency, and cost-effectiveness in biofuel production, making it a viable alternative to fossil fuels. Scientists reprogram metabolic pathways in microorganisms such as yeast, bacteria, and algae to improve biofuel production.Genetic modifications enable microbes to convert sugars, cellulose, and even CO? into bioethanol, biodiesel, biobutanol, and biohydrogen. Escherichia coli and Saccharomyces cerevisiae have been engineered to efficiently produce isobutanol, a biofuel with superior energy content and fuel compatibility. Traditional bioethanol production faces challenges in breaking down lignocellulosic biomass (e.g., agricultural residues, wood, and grasses).Synthetic biology enables microbes to express customized enzymes (e.g., cellulases, hemicellulases) that efficiently degrade cellulose and hemicellulose into fermentable sugars. Algae are naturally capable of producing lipids (for biodiesel) and hydrogen (for biohydrogen fuel cells).Synthetic biology enhances lipid metabolism in algae to increase oil content and improve conversion efficiency. Advances in CRISPR gene editing, synthetic genomes, and AI-driven bioengineering are accelerating biofuel innovation. Researchers are developing synthetic microbes that self-optimize, leading to more efficient, sustainable, and cost-effective biofuel production.With growing investment in clean energy and policy incentives, synthetic biology will play a crucial role in the global transition to renewable biofuels, reducing carbon emissions and enhancing energy security.

• Biogas & Biomethane

Biogas and biomethane are two renewable energy sources derived from organic materials through anaerobic digestion and upgrading processes. These biofuels offer an environmentally friendly alternative to fossil fuels, contributing to energy security, waste management, and greenhouse gas (GHG) reduction. Biogas is a mixture of gases, primarily composed of methane (CH?) (50-65%) and carbon dioxide (CO?) (35-50%), along with trace gases like hydrogen sulfide (H?S) and nitrogen.It is produced through anaerobic digestion (AD), where microorganisms break down organic matter such as agricultural residues, food waste, sewage sludge, and animal manure in oxygen-free conditions.Biogas can be used directly for cooking, heating, and electricity generation in combined heat and power (CHP) plants. Biomethane, also called renewable natural gas (RNG), is a purified form of biogas where CO?, H?S, and other impurities are removed, leaving almost pure methane (≥ 95%).It has the same chemical composition as natural gas, making it compatible with existing gas infrastructure for transportation, heating, and power generation. rganic waste such as crop residues, manure, food waste, and wastewater sludge. hydrolysis breakdown of complex organic matter into simple molecules. To be used in natural gas grids and vehicles, biogas undergoes purification through methods like:water scrubbing removes co? and h?s.pressure swing adsorption (psa) separates gases based on molecular size.chemical absorption  uses chemical solvents to absorb co?.membrane separation filters out co? while keeping ch?.Acidogenesis  conversion into volatile fatty acids.Acetogenesis – further conversion into acetic acid, hydrogen, and co?.Methanogens – microbes convert intermediates into methane and co?.

• Waste-to-Energy Technologies

Waste-to-energy (WTE) technologies play a crucial role in converting municipal, industrial, and agricultural waste into usable energy such as electricity, heat, and fuels. These technologies help address waste management challenges, reduce landfill usage, and contribute to renewable energy generation, supporting global efforts toward sustainability and a circular economy. Waste-to-energy processes convert organic and non-organic waste into energy in the form of electricity, heat, or biofuels. Direct burning of waste at high temperatures (850–1,100°C) to produce heat, steam, and electricity. Partial combustion of waste at high temperatures (700–1,500°C) with limited oxygen, converting it into syngas (H?, CO, CH?) for energy generation. Decomposition of waste at 500–900°C in an oxygen-free environment to produce bio-oil, syngas, and biochar. Microbial breakdown of organic waste (food scraps, sewage, manure) in an oxygen-free environment, producing biogas (CH?, CO?) and digestate. Converts sugar-rich waste (agricultural residues, food waste, wood chips) into bioethanol through microbial fermentation. Non-recyclable solid waste is shredded, dried, and compressed into fuel pellets for industrial combustion. Waste-to-energy technologies will continue to play a vital role in global sustainability, transforming waste into a valuable resource while reducing environmental impact.

• Microbial Fuel Cells (MFCs)

Microbial Fuel Cells (MFCs) are innovative bioelectrochemical devices that utilize microorganisms to convert organic matter into electricity. These systems are a promising alternative for sustainable energy production, wastewater treatment, and bioremediation. By leveraging the natural metabolic processes of bacteria, MFCs provide a renewable and environmentally friendly solution for power generation. MFCs operate by using electrogenic bacteria that break down organic substrates and release electrons in the process. Where bacteria consume organic material and release electrons. electrons combine with protons and an electron acceptor (usually oxygen) to form water. Separates the chambers and allows proton flow while preventing oxygen diffusion. Conduct electricity, enabling electron transfer to generate current. Separate anode and cathode chambers connected by a proton exchange membrane (PEM).Higher efficiency but more complex in structure. Require electron shuttles like methylene blue or ferricyanide to transport electrons. Utilize electrogenic bacteria (e.g., Geobacter, Shewanella) that naturally transfer electrons. MFC technology represents a groundbreaking intersection of microbiology and renewable energy, paving the way for sustainable bioelectricity and green waste management.

• Pyrolysis & Gasification

Pyrolysis and gasification are two key thermochemical conversion technologies that play a vital role in the production of biofuels, syngas, and other valuable products from biomass and waste materials. These processes are gaining increasing attention due to their ability to efficiently convert organic matter into cleaner energy sources, reducing reliance on fossil fuels and mitigating environmental concerns. While both pyrolysis and gasification involve the thermal breakdown of feedstocks, they differ in their operating conditions, reaction pathways, and end products.Pyrolysis is a process in which biomass or waste materials are heated in the absence of oxygen, causing the feedstock to decompose into three primary products: biochar, bio-oil, and syngas. The temperature range for pyrolysis typically falls between 300°C and 700°C. Depending on the processing conditions, pyrolysis can be classified into slow, fast, or flash pyrolysis. Slow pyrolysis occurs at lower temperatures with longer residence times, favoring biochar production, which is valuable for soil amendment and carbon sequestration. Fast pyrolysis, on the other hand, is conducted at higher temperatures and shorter residence times, maximizing the yield of bio-oil, which can be upgraded into biofuels for transportation. Flash pyrolysis operates at even higher heating rates, enhancing the production of volatile compounds that can be further refined into valuable chemicals. One of the major advantages of pyrolysis is its ability to process diverse feedstocks, including agricultural residues, forestry waste, and municipal solid waste, offering a flexible approach to sustainable energy generation.

• Hydrothermal Liquefaction (HTL)

Hydrothermal Liquefaction (HTL) is an advanced thermochemical process that converts wet biomass into bio-crude oil, syngas, and valuable biochemicals by using high temperatures (250°C–400°C) and moderate-to-high pressures (10–25 MPa) in a water-based environment. Unlike traditional biofuel production methods that require extensive drying of biomass, HTL effectively processes wet feedstocks such as algae, sewage sludge, food waste, and agricultural residues, making it an efficient and sustainable technology for biofuel generation. The process mimics the natural geological conditions responsible for crude oil formation but accelerates it to a matter of hours rather than millions of years, providing a promising alternative to fossil fuels.The HTL process involves the decomposition of complex organic molecules under subcritical or supercritical water conditions. At these high temperatures and pressures, water acts as both a solvent and a reactant, facilitating the breakdown of biomass into simpler organic compounds. The process occurs in four key stages: hydrolysis, depolymerization, repolymerization, and phase separation. During hydrolysis, macromolecules such as carbohydrates, proteins, and lipids are broken down into smaller molecules. In the depolymerization stage, these intermediates undergo further cleavage, forming various oxygenated compounds. Repolymerization leads to the formation of bio-crude oil, while phase separation allows for the recovery of different fractions, including aqueous, gaseous, and solid residues. The bio-crude oil produced through HTL has a high energy content and can be further upgraded through catalytic hydroprocessing to produce renewable diesel, jet fuel, and other valuable hydrocarbons.

• Electrofuels (E-fuels)

Electrofuels (E-fuels) are synthetic fuels produced using renewable electricity, water, and carbon dioxide (CO?) through a process known as power-to-liquid (PtL) or power-to-gas (PtG) conversion. Unlike conventional fossil fuels, E-fuels are generated through electrochemical and thermochemical pathways that utilize surplus renewable energy, such as wind, solar, or hydroelectric power, to drive fuel synthesis. These fuels include e-methanol, e-diesel, e-kerosene, and e-methane, which can serve as direct replacements for traditional liquid and gaseous fuels. Given the global push toward carbon neutrality and sustainable energy solutions, E-fuels have gained increasing attention as a viable alternative to decarbonize hard-to-abate sectors, such as aviation, maritime shipping, and heavy-duty transport, where direct electrification is challenging. The production of E-fuels typically involves three key steps: electrolysis, carbon capture, and fuel synthesis. Electrolysis is the first stage, where water (H?O) is split into hydrogen (H?) and oxygen (O?) using renewable electricity. Proton exchange membrane (PEM), alkaline, and solid oxide electrolyzers are commonly used to generate green hydrogen, which serves as a crucial feedstock for subsequent fuel synthesis. The second stage involves carbon capture, where CO? is sourced either from industrial emissions (carbon capture, utilization, and storage—CCUS) or directly from the atmosphere (direct air capture—DAC). The captured CO? is then combined with hydrogen in the final synthesis step, where various catalytic processes, such as Fischer-Tropsch synthesis, methanol synthesis, or Sabatier reactions, are employed to produce liquid or gaseous hydrocarbons that closely resemble conventional fossil fuels.

• Carbon Capture & Bioenergy (BECCS)

Bioenergy with Carbon Capture and Storage (BECCS) is an innovative and essential technology for achieving negative carbon emissions while generating renewable energy. It combines bioenergy production with carbon capture and storage (CCS), effectively removing carbon dioxide (CO?) from the atmosphere and preventing it from re-entering the carbon cycle. BECCS is regarded as one of the most promising solutions for meeting global climate targets, including the Paris Agreement’s goal of limiting global warming to well below 2°C. The process begins with the cultivation of biomass, such as crops, agricultural residues, or dedicated energy plants, which absorb atmospheric CO? through photosynthesis. This biomass is then processed to generate biofuels, biogas, or bioelectricity through various conversion methods, such as combustion, gasification, or fermentation. Instead of releasing CO? into the atmosphere during energy production, BECCS captures the emissions and transports them to underground geological formations for long-term storage or utilization in industrial applications.One of the key advantages of BECCS is its ability to achieve negative emissions, meaning it removes more CO? from the atmosphere than it emits. This makes it a crucial tool for offsetting emissions from hard-to-decarbonize sectors like aviation, heavy industry, and agriculture. By integrating CCS with bioenergy production, BECCS enhances the sustainability of biofuels and biopower while contributing to long-term carbon neutrality. The captured CO? can be stored in deep saline aquifers, depleted oil and gas reservoirs, or basalt formations, ensuring that it remains sequestered for thousands of years. Alternatively, it can be utilized in processes such as enhanced oil recovery (EOR), synthetic fuel production, or carbon-based material manufacturing. 

• Lignocellulosic Biomass

Lignocellulosic biomass is one of the most abundant and renewable sources of organic material on Earth, making it a promising feedstock for biofuel production and sustainable energy applications. It consists of three primary components: cellulose, hemicellulose, and lignin, which provide structural integrity to plants. Found in agricultural residues (such as corn stover and wheat straw), forestry waste (such as wood chips and sawdust), and dedicated energy crops (such as switchgrass and miscanthus), lignocellulosic biomass offers a non-food alternative to conventional biofuel sources like sugarcane and corn. The use of lignocellulosic biomass in biofuel production can significantly reduce greenhouse gas emissions, decrease dependence on fossil fuels, and enhance energy security. However, its complex structure presents challenges in conversion processes, requiring advanced technologies for efficient breakdown and utilization.The conversion of lignocellulosic biomass into biofuels typically follows biochemical or thermochemical pathways. The biochemical approach involves enzymatic hydrolysis, where enzymes break down cellulose and hemicellulose into fermentable sugars, which are then converted into ethanol by microorganisms. This process, known as cellulosic ethanol production, has gained traction as a second-generation biofuel technology with the potential to produce fuel without competing with food supply. However, the presence of lignin, a highly resistant polymer, poses a challenge to enzymatic hydrolysis, often necessitating pretreatment methods such as acid hydrolysis, steam explosion, or ionic liquid treatment to break down the lignocellulosic matrix. 

• Drop-in Biofuels

Drop-in biofuels are renewable fuels that can directly replace conventional petroleum-based fuels without requiring modifications to existing engines, fuel infrastructure, or distribution systems. These biofuels are chemically similar to fossil fuels, making them an attractive alternative for reducing carbon emissions while maintaining compatibility with current transportation and energy systems. Drop-in biofuels can be derived from various feedstocks, including biomass, agricultural waste, algae, and synthetic biological processes. Unlike first-generation biofuels such as ethanol and biodiesel, which often require blending with fossil fuels and have compatibility limitations, drop-in biofuels can function as direct substitutes for gasoline, diesel, and jet fuel. This makes them particularly useful for industries that rely heavily on liquid fuels, such as aviation, maritime transport, and heavy-duty trucking.The production of drop-in biofuels involves several advanced processes, including hydroprocessing, gasification, pyrolysis, and Fischer-Tropsch synthesis. Hydroprocessed esters and fatty acids (HEFA) biofuels are among the most commercially developed drop-in biofuels and are primarily used in aviation. This process involves treating vegetable oils, animal fats, or waste oils with hydrogen to remove oxygen and create hydrocarbons similar to those found in conventional jet fuel. Another promising pathway is biomass-to-liquid (BTL) conversion, where lignocellulosic biomass undergoes gasification to produce syngas, which is then converted into liquid fuels via Fischer-Tropsch synthesis. 

• Biofuel Sustainability & Policy

The global shift toward renewable energy has increased interest in biofuels as a sustainable alternative to fossil fuels. Derived from organic materials such as crops, agricultural waste, and algae, biofuels provide an opportunity to reduce greenhouse gas (GHG) emissions while promoting energy security. However, biofuel sustainability is complex, requiring a balance between environmental, economic, and social considerations. Policies play a crucial role in ensuring that biofuels contribute to sustainability goals without exacerbating issues such as deforestation, food insecurity, and water consumption.One of the key environmental benefits of biofuels is their potential to lower carbon emissions. Compared to fossil fuels, biofuels such as ethanol and biodiesel produce fewer pollutants and are considered carbon-neutral because the carbon dioxide absorbed by plants during growth offsets the emissions released during combustion. However, the sustainability of biofuels depends on production methods. First-generation biofuels, derived from food crops like corn and sugarcane, have raised concerns about land use changes, deforestation, and food security. In contrast, second-generation biofuels, made from non-food biomass such as agricultural waste and wood residues, and third-generation biofuels from algae, offer more sustainable alternatives by reducing competition with food production and utilizing waste resources. Water and land use are critical challenges in biofuel sustainability. Large-scale biofuel production requires significant amounts of water for irrigation and processing, potentially leading to water scarcity in regions already experiencing shortages. Additionally, expanding biofuel crops may lead to deforestation, habitat destruction, and biodiversity loss.

• Circular Economy in Bioenergy

The circular economy in bioenergy focuses on minimizing waste and maximizing resource efficiency by integrating sustainable practices into biomass production, energy conversion, and byproduct utilization. Unlike the traditional linear model of "take, make, dispose," a circular approach ensures that biological resources are reused, recycled, and regenerated to enhance sustainability. In bioenergy, agricultural residues, forestry waste, and organic byproducts from industries are repurposed to produce biofuels, biogas, and bio-based chemicals. This not only reduces dependency on fossil fuels but also lowers greenhouse gas emissions and promotes carbon neutrality. Additionally, biochar, a byproduct of bioenergy production, can enhance soil fertility and sequester carbon, further contributing to environmental benefits. Policies supporting circular bioenergy include incentives for waste-to-energy technologies, sustainable land management, and bio-based product innovation. Technological advancements such as anaerobic digestion, pyrolysis, and biochemical conversion enable efficient resource recovery and energy optimization. Moreover, integrating bioenergy with other renewable sources, such as solar and wind, creates a more resilient and sustainable energy system. A circular bioenergy approach fosters economic growth, reduces environmental impact, and supports the transition toward a low-carbon economy. By closing the loop on biomass utilization, the circular economy in bioenergy ensures long-term sustainability while addressing global energy and climate challenges.

• Artificial Photosynthesis for Fuels

Artificial photosynthesis is a revolutionary technology that mimics natural photosynthesis to convert sunlight, water, and carbon dioxide into renewable fuels such as hydrogen and hydrocarbons. This process involves photoelectrochemical (PEC) and photocatalytic systems, where specialized materials like semiconductors capture solar energy to drive chemical reactions that split water into hydrogen and oxygen or reduce carbon dioxide into liquid fuels. Unlike conventional biofuels, artificial photosynthesis does not rely on biomass, reducing land and water usage while directly utilizing atmospheric CO?, contributing to carbon neutrality. Advances in catalyst design, nanomaterials, and molecular engineering have significantly improved energy efficiency and reaction rates, making artificial photosynthesis a promising alternative to fossil fuels. However, challenges remain in scalability, cost reduction, and stability of catalytic systems. Governments and research institutions worldwide are investing in this technology to develop economically viable solutions for large-scale fuel production. If successfully commercialized, artificial photosynthesis could provide a sustainable pathway for clean energy, reducing greenhouse gas emissions while supporting global energy security. Integrating this technology with existing renewable energy sources, such as solar and wind, can further enhance its viability, paving the way for a future powered by carbon-neutral fuels derived from sunlight.

• Plastics-to-Biofuels

Plastics-to-biofuels technology offers an innovative approach to addressing plastic waste while producing renewable energy. With millions of tons of plastic waste accumulating globally, converting non-recyclable plastics into biofuels presents a sustainable solution to both environmental pollution and energy shortages. This process primarily relies on thermochemical methods such as pyrolysis, gasification, and hydrothermal liquefaction, where plastic waste is broken down under high temperatures in the absence of oxygen to produce liquid bio-oil, syngas, and other valuable chemicals. Pyrolysis is the most widely used method, yielding bio-oil that can be refined into diesel, gasoline, or jet fuel, providing an alternative to fossil fuels. One of the significant advantages of plastics-to-biofuels technology is its potential to reduce landfill waste and ocean pollution while generating energy from discarded plastics that would otherwise persist in the environment for centuries. Additionally, this approach reduces reliance on crude oil, lowers greenhouse gas emissions compared to traditional petroleum refining, and supports circular economy principles by reintroducing waste into the energy cycle. However, challenges such as feedstock contamination, process scalability, and emissions control must be addressed to ensure sustainability. Advanced catalysts, improved refining techniques, and stringent environmental regulations are essential for optimizing efficiency and minimizing toxic byproducts.

• Second & Third-Generation Biofuels

Second- and third-generation biofuels represent significant advancements in renewable energy, addressing the limitations of first-generation biofuels derived from food crops. Second-generation biofuels are produced from non-food biomass, including agricultural residues, forestry waste, and dedicated energy crops such as switchgrass and miscanthus. These biofuels offer higher sustainability by reducing competition with food production, minimizing land use concerns, and utilizing waste materials that would otherwise contribute to environmental degradation. Advanced conversion technologies such as cellulosic ethanol production, gasification, and biochemical processes improve the efficiency of second-generation biofuels while lowering greenhouse gas emissions. However, challenges such as high production costs, complex processing, and the need for improved enzyme technologies remain barriers to large-scale adoption.Third-generation biofuels, primarily derived from algae and other microorganisms, offer even greater potential for sustainable energy. Algae can produce high yields of bio-oil, which can be refined into biodiesel, jet fuel, and other hydrocarbons. Unlike terrestrial crops, algae require minimal land, can grow in saline or wastewater, and capture carbon dioxide, making them highly efficient for biofuel production. Additionally, algae-based biofuels have higher energy density and yield compared to first- and second-generation alternatives. Despite their promise, third-generation biofuels face challenges such as high cultivation costs, scalability issues, and the need for more efficient harvesting and extraction techniques.Biofuel Catalysts & Enzymes

• Techno-Economic Analysis of Biofuels

Techno-economic analysis (TEA) of biofuels is essential for assessing their feasibility, cost-effectiveness, and long-term viability compared to fossil fuels and other renewable energy sources. This analysis integrates technical performance with economic considerations, including feedstock costs, production processes, capital investment, operating expenses, and market competitiveness. The choice of feedstock significantly influences the economic viability of biofuels, as first-generation biofuels from food crops often face price volatility, whereas second- and third-generation biofuels derived from lignocellulosic biomass and algae offer higher sustainability but require advanced processing technologies. Production costs depend on factors such as biomass availability, conversion efficiency, and energy input, with thermochemical (pyrolysis, gasification) and biochemical (fermentation, enzymatic hydrolysis) pathways affecting overall expenses.Capital investment in biofuel refineries, including infrastructure, equipment, and technology development, remains a major economic barrier. While large-scale biorefineries benefit from economies of scale, small and decentralized facilities face higher per-unit costs. Operating expenses, including enzyme and catalyst costs, labor, energy consumption, and waste management, further impact economic viability. Additionally, policy incentives such as subsidies, carbon credits, and tax benefits play a crucial role in reducing financial risks and promoting biofuel adoption. Market factors, including crude oil prices, regulatory policies, and consumer demand, influence biofuel competitiveness, with fluctuating fossil fuel prices affecting investment decisions.Life cycle assessment (LCA) is often integrated into TEA to evaluate environmental impacts alongside economic performance, ensuring biofuels contribute to carbon reduction and energy security.

The development of integrated biorefineries that can produce multiple bio-based products, including bioethanol, biodiesel, and biogas, has also enhanced market prospects.The bioethanol segment remains the dominant sector within the biofuels industry, largely due to its widespread use as a gasoline additive. The United States and Brazil are the leading producers of bioethanol, with corn and sugarcane serving as primary feedstocks, respectively. Brazil’s Proálcool program has significantly contributed to the country's leadership in sugarcane-based ethanol production, while the U.S. continues to expand its corn ethanol industry, supported by government subsidies and investments in ethanol-blending infrastructure. The biodiesel market, on the other hand, has seen substantial growth in Europe, with countries like Germany, France, and Spain investing in rapeseed and soybean-based biodiesel production to meet renewable energy targets.

Asia-Pacific is emerging as a key growth region for biofuels and bioenergy due to increasing energy demand, rapid industrialization, and favorable government policies. Countries like India and China have introduced ethanol-blending mandates to reduce crude oil imports and enhance energy security. India has set an ambitious target of achieving a 20% ethanol blend in gasoline by 2025, while China has invested heavily in biomass power generation and waste-to-energy projects. Southeast Asian nations, particularly Indonesia and Malaysia, are capitalizing on palm oil biodiesel production, although concerns regarding deforestation and sustainability have led to stricter regulatory scrutiny from international markets.The Middle East and Africa are also witnessing growing interest in bioenergy, driven by efforts to diversify energy sources and reduce reliance on fossil fuels. Countries like South Africa, Nigeria, and Kenya are exploring bioethanol and biodiesel production from sugarcane, cassava, and jatropha. The development of biogas projects in rural areas has also provided sustainable energy solutions for off-grid communities. In the Middle East, countries like Saudi Arabia and the UAE are investing in algae-based biofuels as part of their broader renewable energy strategies.

Past Conference

18th World Congress on Biofuels and Bioenergy’ during March 28-29, 2024 at Dubai, UAE which includes prompt keynote presentations, Oral talks, Poster presentations and Exhibitions.

Biomass and Bioenergy Conference 2024 is the learning of how renewable energy resource derived from the carbonaceous waste of various human and natural activities. It is derived from numerous sources, including the by-products from the timber industry, agricultural crops, raw material from the forest, major parts of household waste and wood. As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into thermal, chemical, and biochemical methods.

Importance and Scope:

Energy is an essential input for social development and economic growth. The socioeconomic impacts on a local economy arising from providing power through renewable resources instead of conventional generation technologies are very important. Liquid biofuels (mainly ethanol and biodiesel) have been investigated as alternative resources to resolve the demanding consumption of conventional gasoline and diesel fuels from fossil fuels. Social, political, economic, and environmental aspects related to biofuels are overviewed and issues associated with future liquid fuels demand are proposed to encourage energy experts to contribute to the emerging field of energy research. The promising transportation fuels are ethanol, biodiesel, hydrogen, biogas, and natural gas. Electricity and hydrogen are principal energy carriers which can be produced from all primary energy sources.
