This is a plastic designed to disintegrate when exposed to light.
Some photodegradable and biodegradable plastics are already in use in agriculture, Farmers cover their fields with plastic sheeting that acts as a mulch. You use less water, because it keeps the moisture in the soil. It keeps the weeds down. You use less pesticide. It warms the ground so you can extend the growing season.” The slow degradation of the plastic allows the ground to be plowed again later without having to take up the plastic and dispose of it. A second important main area of use is for packaging materials like plastic 6-pack rings that often litter the roadsides and build up in landfills.
