Our PLA cups are crafted with food grade PLA material. PLA, also known as Polylactic Acid, which is derived from plant-based starch from renewable resources, such as corn, sugar cane, etc., is a true “green plastic”. While enjoying the drink, you are also lightening the burden for the earth, because this cup can be completely decomposed by microorganisms under specific soil conditions, and eventually become carbon dioxide and water that nourish the earth, leaving no trace of pollution, so that every sip of drinking water becomes a gentle care for the environment.
