These may be substances which can be obtained directly from plant or animal material, or else. Substances obtained by processing a plant or animal material, which should not contain added synthetic and / or fossil derived ingredients during processing. Examples of such processing steps are the reaction with other plant or animal materials, the processing by microorganisms (eg fermentation) and / or the polymerization or polycondensation of substances obtained from vegetable or animal material. Binders which are obtainable from renewable raw materials may also be present as such in vegetable or animal materials (eg starch), or may be obtained by processing substances present in vegetable or animal material (eg cellulose acetate). In addition, they can also be obtained by polymerization of monomers which are present in vegetable or animal materials or which are obtained by processing, eg fermentation, of such materials (eg polylactic acid).
