Petrochemical-free silk protein for sustainable product development MoreLess

Cocoon Labs, also known as Cocoon Biotech, is a materials science company focused on creating sustainable alternatives to petrochemicals. The company's core offering is EcoSilk™, a natural and biodegradable protein derived from silkworm cocoons. This versatile material is designed to be used as a sustainable ingredient in a wide array of products across the healthcare, consumer goods, and industrial sectors, replacing microplastics and other harmful components derived from oil and natural gas.

Founded in 2013 by Dr. Ailis Tweed-Kent, the company was born from her passion for the intersection of health and the environment. Dr. Tweed-Kent's background includes a B.S. in Chemical Engineering, an M.D. from Harvard Medical School, and medical training at Massachusetts General Hospital, providing a multidisciplinary approach to the company's mission. The business model centers on partnering with companies to help them reduce or eliminate their reliance on petrochemicals by integrating EcoSilk™ into their products. Cocoon Labs leverages expertise in biotechnology, materials science, and green product design to engineer what they term the world's most adaptable and sustainable natural material.
