19/20 10117 Berlin IV MATERIAL, PROPERTIES AND TECHNOLOGY What are bioplastics made of? Today, bioplastics are mostly made of carbohydrate-rich plants such as corn, sugar cane or sugar beet – so-called food crops or first generation feedstock. First generation feedstock is currently the most efficient for the production of bioplastics, as it requires the least amount of land to grow and produces the highest yields. The bioplastics industry is also researching the use of non-food crops (second and third generation feedstock), such as cellulose, with a view to its further use for the production of bioplastics materials. Innovative technologies are focussing on non-edible by-products of the production of food crops, which generates large amounts of cellulosic by-products such as straw, corn stover or bagasse that can be used to produce biopolymers. http://www.european-bioplastics.org/bioplastics/materials/ http://docs.european-bioplastics.org/publications/pp/EuBP_PP_Feedstock_availability.pdf phone fax What types of bioplastics do exist and what properties do they have? Bioplastics are a diverse family of materials with differing properties. There are three main groups: e-mail web Marienstr. 19/20, 10117 Berlin +49.30.28 48 23 50 +49.30.28 48 23 59 firstname.lastname@example.org www.european-bioplastics.org 1. Bio-based (or partially bio-based), durable plastics such as bio-based polyethylene (PE), polyethylene terephthalate (PET) (so-called drop-in solutions), bio-based technical performance polymers, such as numerous polyamides (PA), or (partly) bio-based polyurethanes (PUR); 2. Bio-based and biodegradable, compostable plastics, such as polylactic acid (PLA), polyhydroxyalkanaoates (PHA), polybutylene succinate (PBS), and starch blends; 3. Plastics that are based on fossil resources and are biodegradable, such as PBAT and PCL, but that may well be produced at least partly biobased in the future. Bio-based, durable plastics, such as bio-based PE or bio-based PET, possess properties that are identical to their conventional versions. These bioplastics are technically equivalent to their fossil counterparts; yet, they can help to reduce a product’s carbon footprint. Moreover, they can be mechanically recycled in the according existing recycling streams. Innovative materials such as PLA, PHA, or starch-based materials offer solutions with completely new functionalities such as biodegradability and compostability and in some cases optimised barrier properties. Bioplastics are made from a wide range of renewable BIO-BASED feedstock. Agro-based feedstock – plants that are rich in carbohydrate, such as corn or sugar cane. feedstock – plants that are not eligible for food and feed production.
