Circular by nature: a policy agenda for bio-based materials in a circular economy
A circular economy for bio-based materials can unlock new revenue streams, drive innovation, and strengthen supply chain resilience.
Most bio-based materials are still produced and consumed within linear systems. A circular economy approach changes that by enabling regenerative sourcing, keeping materials in use, valorising by-products and residues, and building business models that decouple revenue from virgin resource extraction.
Pragmatic assessment of meeting the 2030 U.S. sustainable aviation fuel goal
Sustainable aviation fuel (SAF) production is essential for decarbonizing the aviation sector in the short and mid-term as well as maintaining the global competitiveness of U.S. airlines, supporting job creation, and ensuring U.S. energy independence. The near-term U.S. SAF target, set by the SAF Grand Challenge, is 11.4 billion liters (3 billion gallons) of domestic SAF production by 2030, with a minimum 50 % reduction in lifecycle greenhouse gas emissions. In 2024 U S.

Enhanced Degradation and Thermal Stability in Partially Lignin-Derived Polyacetals by Incorporating a Linear Structure
The development of biodegradable polymers derived from renewable resources has been motivated by the environmental impact of plastic waste. The objective of our research is to improve
the degradation rate of spiro-polyacetals by integrating linear acetal units into their structure while preserving their desirable thermomechanical properties. The polymer, VPA-CDVE, was produced by reacting vanillin-based spiro-acetal monomer (VPA) with cyclohexanedimethanol vinyl ether (CDVE). The polyacetal that resulted was characterized using NMR spectroscopy, which
Liquefaction of Corn Stover Pellets before Pretreatment by Enzyme Biocatalysis
Use of lignocellulosic biomass in continuous processes in biorefineries poses challenges due to its recalcitrant properties, feedstock variability, and materials handling of solids at large scale. Limitations include lignin derived inhibitors, and resistance to mixing due to rheological properties of lignocellulosic particulates at high solids loadings.
