The biopolymer share of the plastic market is poised to grow from 1% now to 6 12% by 2021. The current demand for bioplastic, however, is eight times the 2021 expected capacity. Worldwide, the market for bioplastics is projected to reach between $1530 billion by 2021 and $50 billion by 2021. PLA (polylactic acid), a versatile polymer made from cornstarch, is the most wellknown of these socalled biopolymers. A polyethylene alternative from sugarcanebased ethanol has also been launched. Other producers are turning to agriculture and forestry waste as sources rather than using food crops. Among these is Innovia Films whose NatureFlex film is produced from wood pulp (for an application, see page 33 Editor). A matter of semantics COMPOSTABLE, degradable and biodegradable are often mistakenly interchanged… Compostable Plastic is, by ASTM standards, capable of undergoing biological deposition in a post site as part of an available program, such that the plastic is not visually distinguishable and breaks down to carbon dioxide, water, inanic pounds, and biomass, at a rate consistent with known postable materials (. cellulose) and leaves no toxic residue. In order for a plastic to be called postable, three criteria need to be met: Biodegrade break down into CO2, water, biomass at the same rate as cellulose Disintegrate the material is indistinguishable in the post Ecotoxicity the biodegradation does not produce any toxic material and the post can support plant growth. Biodegradable Plastic will degrade from the action of naturally occurring microanism, such as bacteria, fungi etc., over a period of time. Note, that there is no requirement for leaving no toxic residue, and as well as no requirement for the time it needs to take to biodegrade. Degradable Plastic will undergo a significant change in its chemical structure 4 under specific environmental conditions resulting in a loss of some properties. A plastic therefore may be degradable but not biodegradable or it may be biodegradable but not postable.
