#53 CARBIOS
Headquarters: Clermont-Ferrand, France
CARBIOS focuses on multicomponent plastic products with degradable regions that partially degrade and biodegrade when disposed of.
Key Patents in Biodegradable Packaging
Multicomponent Plastic Products with Degradable Regions (US20220177697A1)
Multicomponent plastic products with degradable regions that can partially degrade and biodegrade when disposed in the environment. The products have two or more distinct plastic regions, one region made of a thermoplastic material containing a degrading enzyme to break down a polymer in the adjacent region.
The degrading enzyme region has a lower transformation temperature than the target polymer region. This allows the enzyme to remain active when the product is processed and contacts the target region, initiating partial degradation. The low temperature match prevents full melt of the degrading region during processing. The enzyme-containing region can also have additional fillers or enzymes to further aid degradation.

#58 THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS
Headquarters: Urbana, Illinois, USA
THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOIS develops methods for making microvascular systems with interconnected channels in composite materials.
Key Patents in Biodegradable Packaging
Making Microvascular Systems with Interconnected Channels (US10844185B2)
Making microvascular systems with interconnected channels in composite materials using sacrificial layers that degrade at lower temperatures.
