Plastic beverage containers manufactured from Peter's Packaging Company use a degradable bonding agent (ie cornstarch) to bind together smaller bits of plastic in creating one partially degradable plastic container. On the other hand, plastic beverage containers from Kepsi Packaging are manufactured without binding small bits of plastic together and without using any kind of degradable bonding agent. Managers at Peter's Packaging Company boasted that no less plastic refuse per container is produced when its containers are discarded than when comparable non-biodegradable containers from Kepsi are discarded.
