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.

1 year Anniversary of the Stockholm Declaration - 24 hour Celebration

To mark the one-year anniversary of the Declaration’s signing, we are hosting a 24-hour global webinar May 22–23, 2026, beginning at 3:00 AM EDT / 9:00 AM CEST. Participants are welcome to join at any time during the 24-hour period, from 3:00 AM EDT / 9:00 AM CEST on May 22 through 3:00 AM EDT / 9:00 AM CEST on May 23. Community members from around the world will come together to reflect on progress over the past year, share insights and experiences, and inspire continued action through a series of talks and discussions.

Green chemistry strategies in pulping and biomass valorization: toward a circular bioeconomy

The transition toward a circular bioeconomy demands innovative, sustainable, and efficient technologies for biomass valorization and pulping. Green chemistry strategies, particularly organosolvent pulping pretreatment, are emerging as pivotal solutions to unlock the full potential of lignocellulosic feedstocks. Organosolvent processes employ environmentally benign solvents to selectively fractionate biomass components, enabling the recovery of high-purity cellulose, hemicelluloses, and lignin with minimal environmental footprint.

Green recovery of amorphous silica from silicone waste: Alkali activation and thermal treatment

This study presents a green and sustainable method for recovering high-purity silica from solid silicone by-products derived from industrial silicone oil manufacturing through alkali-assisted sol–gel synthesis, with and without thermal treatment. Sodium hydroxide and sodium carbonate were used to evaluate the effects of alkali type, concentration, and calcination at 800 °C on silica yield, structure, and performance.

South Africa's Policy Framework - Does it support a just Circular Economy transition?

The document, developed by the African Circular Economy Network (ACEN), outlines South Africa’s strategic approach to transitioning towards a circular economy, emphasizing the importance of responsible and inclusive practices through initiatives like the JUST2CE project. It highlights the need for collaboration and innovative business models to enhance sustainability and resource efficiency across various sectors, ultimately fostering economic growth and social equity.

Industrial symbiosis grant funding opportunity (Washington State)

Commerce is now accepting applications for collaborative projects to spur the circular economy, diverting waste streams generated by one industry into beneficial resources for another. Industrial symbiosis project investments help foster a locally resilient supply chain, grow economic opportunities and ultimately reduce environmental impacts in communities across Washington state.

High-purity specialty chemicals and materials from Food Waste

Every year, 1.3 billion tons of food are lost on farms and in processing. However, this food waste stream contains specialty ingredients and chemicals worth as much as $2,000 per ton.

Hyfe is refining waste to value, and unlocking the full value of every crop, utilizing food-safe solvents and catalysis to turn food waste into high-purity specialty chemicals and materials including bioactives, fibers, oils, cellulose, lignin, and dextrose that maximize profits for food manufacturers.
