UNLOCK has also developed compostable seed trays using materials derived from poultry feathers. The trays provide a biodegradable container for growing and transporting plant seedlings while creating a new application for poultry-industry residues.
Unlike conventional plastic seedling containers, the trays are designed for compostable or biodegradable use. They demonstrate how feather-derived materials can be shaped into practical agricultural products beyond films and coatings.
