Description

One of the most common material applications of plastics shredding is the processing of so-called plastic lumps, which are usually generated as a waste product during the extrusion of plastics. The economic potential of this “purge” is enormous. It is expensive to dispose of the unused purge lumps. Recycling offers the possibility of seamlessly reintegrating production scrap into the manufacturing process instead of using new resources.

Call it what you want, we make it small.

Plastics, which accumulate as production waste at the beginning of the extrusion or injection molding process are known as plastic lumps, petrochemical lumps or extrusion lumps. It is also called “purge” in the US.

How are plastic lumps formed?

During injection molding production, there are often production waste and scrap. These occur primarily when molded parts do not meet the desired specifications, edge trims have to be made or injection molded parts are cast on. Moreover, plastic waste also occurs during production breaks, machine tests or in the start-up phases of the machines. If the waste material is pure, it can be returned to production on site. The recycling of start-up lumps reduces the amount of waste and thus effectively reduces the impact on the environment and on disposal costs.
