Abstract
The invention relates to a plastic compound comprising at least one polyolefin and a biological entity that degrades said polyolefin. The invention further relates to a process for preparing a plastic article wherein at least one polyolefin and one biological entity that degrades said polyolefin are mixed at a temperature at which the polyolefin is in a partially or totally molten state.
Claims19
A plastic compound comprising at least one polyolefin, an oxidase that degrades said polyolefin and a biological entity, said biological entity comprising an alcohol dehydrogenase, an aldehyde dehydrogenase or a microorganism that expresses an alcohol dehydrogenase or an aldehyde dehydrogenase, wherein the biological entity degrades at least one oxidation product of the polyolefin and wherein the oxidase and the biological entity are embedded in the mass of the plastic compound.
A process for preparing a plastic article wherein at least one polyolefin, an oxidase that degrades said polyolefin and a biological entity that degrades at least one oxidation product of the polyolefin comprising are mixed at a temperature at which the polyolefin is in a partially or totally molten state, said biological entity comprising an alcohol dehydrogenase, an aldehyde dehydrogenase or a microorganism that expresses an alcohol dehydrogenase or an aldehyde dehydrogenase.
A plastic article containing at least one polyolefin and an oxidase that is able to degrade said polyolefin in said plastic article, and a biological entity that degrades at least one oxidation product of the polyolefin, the biological entity selected from an alcohol dehydrogenase, an aldehyde dehydrogenase and a microorganism that expresses an alcohol dehydrogenase or an aldehyde dehydrogenase.
