At ABLC 2025, there were several discussions highlighting progress and opportunities in the realm of renewable chemicals and materials.
• Diversification beyond Fuels: Several companies and initiatives emphasized the importance of producing a range of products, including chemicals and materials, alongside or instead of just biofuels. This diversification is seen as a way to enhance economic viability and sustainability.
• Biomass as a Key Feedstock: Biomass, in its various forms, is recognized as the primary feedstock for renewable chemicals and materials. This includes agricultural and forestry waste, animal waste, waste biomass, and novel sources like algae and purpose-grown crops. The U.S. has a substantial potential biomass supply that could support the production of both fuels and chemicals.
Specific Companies and Technologies:
◦ Gevo is actively involved in producing renewable chemicals and materials. Their integrated approach aims to bridge the “Renewable World” and the “Hydrocarbon World”. They have achieved firsts in producing fully renewable p-xylene for PET (used in films and fibers) and bio-based butyl rubber. Gevo also highlighted the potential of their Alcohol-to-Jet (ATJ) technology to produce not only SAF but also other products.
◦ Marathon Petroleum has developed its BioForming® technology to create fuels and chemicals from renewable resources. They have partnered with Johnson Matthey to bring this technology to market for the production of BioFormate®, which enables 100% bio-PET. BioFormate® has been used by companies like Coca-Cola and Patagonia, demonstrating market adoption.
◦ BASF highlighted its broad chemical portfolio and its commitment to combining economic success with environmental protection. They presented various technology options for converting biomass to chemicals, acknowledging that the transition will be gradual and petrochemicals will remain important in the near term.
◦ Global Bioenergies focuses on a unique biological process for producing sustainable aviation fuel (SAF) from renewable resources. Their process is also described as having the potential to produce drop-in substitutes for petrochemical molecules.
◦ Hexas is innovating with purpose-grown crops like XanoGrass™ to produce XanoFiber™, which can be used in various bioeconomy products, including boards and bioplastics.
◦ Hyfé is focusing on utilizing food processing waste streams, rich in high-value specialty chemicals, to create profitable facilities.
◦ Haffner Energy’s technology can unlock the potential of biomass to produce not only clean fuels like SAF and methanol but also offers the ability to extract carbon in solid (biochar) or gaseous (CO2) forms, which could be used for chemical production. They are also exploring technologies to produce products from biogenic CO2.
• Co-processing in Refineries: There is growing interest in co-processing biocrudes derived from biomass in existing refinery infrastructure to produce renewable fuels and potentially chemicals. However, challenges related to the quality and handling of biocrudes (e.g., high water content, acidity, metal content) need to be addressed. Standardizing analytical methods and defining critical material attributes for bio-based intermediates are seen as crucial steps to facilitate refinery integration.
• The Role of Fermentation: Fermentation processes are highlighted as a key technology for producing renewable chemicals. Gevo emphasizes how fermentation simplifies highly selective chemical synthesis. Sonata Bio utilizes a biological fermentation process with waste gases to produce ethanol, which can then be used as a building block for other chemicals.
• Biochar as a Co-product: Several biomass conversion technologies, such as Afne Energy’s thermolysis process, produce biochar as a co-product. Biochar has potential applications as a soil amendment and in the production of other materials like activated carbon. It can also generate carbon credits.
• Market Demand and Policy Drivers: Growing demand for sustainable products and the need to meet GHG reduction targets are driving the expansion of the renewable chemicals and materials sector. Policies that reward CO2 abatement, such as those linked to carbon intensity, are expected to favor advanced bioproducts, including chemicals and materials with significant GHG savings.
Challenges and Opportunities: While there is progress, challenges remain in scaling up production, ensuring cost competitiveness, and overcoming technical hurdles associated with different feedstocks and conversion technologies. However, the increasing recognition of the value of biomass beyond fuel applications and the development of innovative technologies present significant opportunities for the growth of the renewable chemicals and materials industry. The need for robust and consistent policies that support the bioeconomy as a whole is crucial for realizing this potential.
In summary, ABLC 2025 showcased a dynamic landscape for renewable chemicals and materials, with various companies advancing innovative technologies and exploring diverse feedstocks to meet the growing demand for sustainable products. The integration of biorenewables into existing infrastructure and the development of supportive policies are seen as key enablers for further progress in this sector.
