Compostable polymer materials produced through microbial fermentation

Shellworks is a materials biotechnology company that develops and manufactures a bio-based, home-compostable polymer produced through microbial fermentation of plant-derived waste feedstocks.

The polymer is formulated to replicate the functional properties of conventional plastic while biodegrading fully in home composting conditions without producing microplastics or toxic residues.

The company supplies the polymer as pellets and finished moulded packaging components, targeting the beauty and personal care sectors.
