Rodepa Plastics put faith in Herbold for post-consumer waste and film recycling
The Netherlands recycler Rodepa Plastics has installed a recycling line from Germany’s Herbold Meckesheim for production of high quality regrind.
The plastics waste consists of low density polyethylene (LDPE) film waste, of which the contamination level could be as high as 50%. In order to separate this type of contamination from film, in the washing line as early as the pre-size reduction step, a wet shredder especially designed for this purpose is used.
To separate unwanted plastics, the process is done by means of a hydrocyclone separation step. Heavier plastic components can be separated from the polyolefin, which attains a higher degree of purity than traditional swim-sink-tanks, according to Herbold.
A further advantage of the hydrocyclone separation step is the high amount of water present in the water circuit, which together with the revolving forces arising due to the hydrocyclone, ensuring a good washing result. Deposits of organic substances, a frequent feature of film from household waste, are easily removed by washing.
The washing line at the Rodepa Plastics site transforms post-consumer film into recycled material that will then be used for the production of bin liners, protective sheets and construction foils. These new products are made up of 100% recycled material from the Herbold film washing line.
Mark Langenhof, Managing Director of Rodepa Plastics, said, “Rodepa has taken a big step forward in recycling contaminated waste that is to newly integrate the production of film. This has only been possible with the best plant engineering. With Herbold Meckesheim we have now found the ideal partner in order to cooperate successfully.”
