A bio-based material
is simply an engineering material
made from substances derived from living matter. These materials are sometimes referred to as biomaterials
, but this word also has another meaning. Strictly the definition could include many common materials such as wood
, but it typically refers to modern materials that have undergone more extensive processing. Unprocessed materials may be called biotic material
Bio-based materials are often biodegradable, but this is not always the case.
