The present invention relates to a masterbatch composition comprising high concentration of biological entities having a polymer-degrading activity and uses thereof for manufacturing biodegradable plastic articles.

The invention relates to a recycling method for producing a polyolefin recyclate, involving the process of removing contaminants from a contaminated polyolefin material, in which the contaminated polyolefin material is soaked in a solvent in a soaking step in order to dissolve contaminants present in the contaminated polyolefin material in the solvent and to remove the solvent and the contaminants dissolved in the solvent from the polyolefin material. According to the invention, prior to the soaking step, a washing step carried out using water, cleaning agents and/or lye. The contaminated polyolefin material is changed by the soaking/solvent recycling method such that (i) more than 90% of the low-molecular chains of below 2000 daltons are removed or washed out, and the average molecular chain length of the polyolefin recyclate is therefore increased, and (ii) the melt volume-flow rate (MVR) of the polyolefin recyclate is reduced to a specified MVR.

Systems and methods for processing a plastic are disclosed. The system includes a feeding device in fluid communication with a cracking unit. A feed stream comprising a plastic is depolymerized in the feeding device at a depolymerization temperature to produce a hydrocarbonaceous wax stream. The hydrocarbonaceous wax stream is then cracked in the cracking unit. The cracking is conducted at a cracking temperature that is lower than, or the same as the depolymerization temperature.
