biodegradable plastic 生分解性プラスチック
ライフサイエンス / 社会・生活 / ハイテクノロジー
A type of plastic that breaks down into hydrogen, oxygen, and carbon within 1 to 2 weeks when mixed with compost. The accumulation of plastic materials in landfills had been a problem since the latter half of the 20th century until the development of this plastic at the beginning of the 21st. Modern biodegradable plastic is made primarily out of a lactic acid polymer, with the lactic acid obtained by fermenting various starches. It can then be injection molded, or processed into film or fiber. It has simultaneously solved both the waste disposal problem and the oxygen replenishment problem on Beyond Coast, with all products required to be made out of biodegradable plastic wherever possible.
