Corn Starch Biocompostables – What Are They?

Corn starch biocompostables are in essence biocompostable plastics made from renewable, biodegradable corn starch. Thankfully, plastics technology has come a long way. All traditional plastic is made from petroleum products. The production of petroleum-based plastics involves all kinds of chemicals, some of which have raised health concerns among consumers. Such plastics do not biodegrade. They are made with a non-renewable resource: petroleum. There are environmental and health concerns associated with conventional plastics.

How Are They Made?

As the name implies, they are made from corn starch. The starch is converted into a polymer, the main ingredient in materials that have a plastic-like feel. The plastics can be clear or opaque, soft or hard. A kind of acid called polylactic acid (PLA) is made from the corn starch. This is why they are sometimes called PLA plastics.

PLA plastics are molded the same way conventional plastic is. They can be molded, extruded, or shaped by heating and cooling (thermal shaping).
