Scientists have discovered a way to convert widely used plastics into new materials with distinct properties that degrade more rapidly. Applying this new process to upcycle existing plastics—such as those used for food packaging and in 3D printing—could contribute to tackling global plastic pollution issues, researchers say.

This is an important advance as some 99% of plastics in circulation are not biodegradable, and the eco-friendly alternatives that do exist often break down slowly or require high temperatures and harsh chemicals, the team says.

Welsh scientists have developed a new biodegradable plastic made from seaweed that could one day replace fossil fuel-based food packaging.

Researchers at Aberystwyth University say the material, created using seaweed extracts, could offer a more sustainable alternative to conventional plastic films widely used in the food industry.

The findings, published in the journal Algal Research, come amid growing concern over the environmental impact of plastic waste and pollution in the world’s oceans.

Sun Chemical launches its next-generation SolarFlex FSP UV flexographic ink range, providing label and packaging manufacturers with a food-compliant solution that meets evolving regulatory requirements while delivering the productivity, print quality and low migration performance demanded by the packaging market.

• Z1ro has developed molded fiber packaging using non-wood biomass such as bamboo residues, hemp hurd, and fallen leaves.
• The material is designed to replace plastic trays, foam inserts, and virgin wood pulp.
• Z1ro says its lignin-preserving process can reduce material use, improve recyclability, and lower reliance on forest-based raw materials.

Z1ro, a France-based materials deep-tech company, has engineered bio-designed molded fiber packaging derived from non-wood biomass sources.
