Corn Plastic 101

There are many interesting and unique ways to go green these days. One of the less well-known methods is substituting corn plastic for petroleum-plastic items. Yep — plastic can be made from corn! Although the technology to create plastics from corn has been around for over 20 years, it was too expensive and therefore only used sparingly. Now, recent advancements means corn plastic could be making a comeback.

Corn plastic is commonly known within the plastics industry as Polylactic acid (PLA), and it is produced by fermenting the natural starches in the plant. Because PLA comes from renewable, carbon-absorbing plants, it is considered more carbon-neutral than petroleum-based plastics. Another added benefit is the fact that no harmful or toxic fumes are released when PLA is burned.

One of the main selling points of PLA is the fact that it is compostable. Under industrial composting conditions, corn plastic can biodegrade into oxygen and water in less than 90 days. In landfills however, this process takes significantly longer. Because most corn plastic usually isn't recycled under optimal conditions, it is not considered a cure-all — but it is still a reasonable eco-friendly alternative to oil-based plastics for the time being. Scientists and engineers are continually improving corn plastics to create versions that will break down quicker in less-than-perfect conditions.

The next time you want to run a promotional campaign, consider using products fashioned from corn plastic, such as mugs, pens, or coasters. These office necessities are sold by the millions each year, so replacing them with corn plastic versions can make a big difference and help sustainable business practices gain a foothoold in every industry.
