PLA is a compostable bioplastic derived from plant sugars. PLA stands for polylactic acid. It can be made from any sugar, such as corn starch, cassava, sugar cane, or sugar beet. NatureWorks is the world’s largest producer of PLA, and a key partner to Vegware.

PLA is a fully biodegradable thermoplastic polymer consisting of renewable raw materials. PLA is a thermoplastic, meaning it will turn into a liquid in its melting point of 150 to 160 Celsius. A nifty feature of thermoplastics is that they can be heated, set upon cooling, and reheated again to form other shapes without any degradation. PLA production is a popular idea as it represents the fulfillment of the dream of cost-efficient, non-petroleum plastic production. The huge benefit of PLA as a bioplastic is its versatility and the fact that it naturally degrades when exposed to the environment. For example, a PLA bottle left in the ocean would typically degrade in six to 24 The other problem we find with PLA is, people often think it is recyclable, just like our standard plastic, and therefore it ends up in the same bin. This misconception causes lots of problems in the plastic recycling world as your PLA products to act as a contaminant in hydrocarbon-based resins such as PE, PP, PET, and PS. Healthcare and Medical industry: PLA plastic is biocompatible, meaning that it can be used for devices in the human body with minimum inflammation and infection.

A compostable plastic is defined by the standards association ASTM Polylactic Acid, or PLA, is probably the most commonly recognized bioplastic.

NatureWorks is the world’s largest producer of PLA, and a key partner to Vegware. PLA plastics are plant-derived plastics that are now used extensively in food packaging as ‘biodegradable’, ‘compostable’ or ‘recyclable’ alternatives to typical polymers. PLA is a thermoplastic, further classified as a polyester plastic.

Most of them are made from PLA, a bioplastic. Bioplastic is a new type of plastic generally made from plant starch or sugars, and not from petroleum. Having the name BIO in the plastic can be a bit misleading since they don’t just biodegrade like a banana peel. So is PLA really compostable?
