With a world market in excess of 300 million tonnes p.a., plastics are a necessity in today’s economy. Normally they are produced from crude oil products. Many of the materials utilised to date can, however, also be made from renewable resources. In recent years, the face of the plastic industry has begun to change. Numerous biobased plastic materials have been developed and today represent a proven alternative to their conventional counterparts. Most fossil fuel based plastics could technically be substituted with biobased plastics. As bioplastic technologies and costs of production change, it will increasingly happen.
Bioplastics offer a broad range of functionalities optimised for each type of application and, in addition, can reduce the impact on the environment. For example and organic waste collection bag is designed to breathe, reducing the weight of the contents and the tendency for the waste to putrefy, thus enabling convenient and clean collection and diversion of organic waste from landfill to composting. A chocolate wrap provides the barrier properties required to protect the product, but can be disposed of to composting along with other organic waste.
