Cornstarch products, such as pens, rulers, mugs, luggage tags, keyrings and more, use renewable agricultural derived starch to make bioplastic polymers that can be made into oil-based plastic substitutes. Cornstarch plastic products look and feel just like regular plastic, but they are 100% biodegradable and compostable.
Cornstarch products are preferable mainly because:
- They are made from a renewable plant material
- They replace fossil fuel based products
- They are theoretically recyclable if systems are actually put in place
- They are biodegradable and compostable at the end of their useful lives
Producing PLA uses 65 percent less energy than producing conventional plastics, according to an independent analysis commissioned by NatureWorks. It also generates 68 percent fewer greenhouse gases, and contains no toxins.
Probably the greatest contribution that cornstarch PLA can make is in the area of packaging: in the USA alone, conventional plastic packaging uses an estimated 200,000 barrels of oil a day!
