Today, there is a bioplastic alternative for almost every conventional plastic material and corresponding application. Bioplastics – plastics that are biobased, biodegradable, or both – often have the same properties as conventional plastics and offer additional advantages, such as a reduced carbon footprint or additional waste management options such as industrial composting.   Some bioplastics offer additional functionalities, such as biodegradability or compostability, and improved properties, such as increased [...]

There is no common agreement on a minimal value yet due to varying regional regulations in Europe. In Japan an industry-wide commitment sets the “biomass margin” at “25 percent renewable material”. According to the USDA Bio-preferred Programme, “the minimum share of renewable material ranges from 7 to 95 percent” depending on defined product [...]

Bioplastics are a diverse family of materials with differing properties. There are three main groups:  Biobased (or partially biobased), durable plastics such as biobased polyethylene (bio-PE), polyethylene terephthalate (bio-PET) (so-called drop-in solutions), biobased technical performance polymers, such as numerous polyamides (bio-PA), or (partly) biobased polyurethanes (PUR);    Biobased and biodegradable, compostable plastics, such as polylactic acid (PLA), polyhydroxyalkanaoates (PHA), polybutylene succinate (PBS), and starch blends;   Plastics that are based on fossil [...]

Today, bioplastics are mostly made of carbohydrate-rich plants such as corn, sugar cane or sugar beet – so-called agricultural feedstocks. Agricultural feedstocks are currently the most efficient for the production of bioplastics, as they require the least amount of land to grow and produce the highest yields.  The bioplastics industry is also using non-edible crops such as cellulose for the production of biobased materials. Innovative technologies focus on non-edible by-products of the [...]
