ESE World, a manufacturer of temporary storage systems for waste and recyclables, has conducted scientific tests to demonstrate the recycling properties of the high-density polyethylene (HDPE), a polyethylene thermoplastic made from petroleum.
RPC Group’s subsidiary ESE World said it has established a controlled experimental model at its undisclosed production facility to assess HDPE’s ability to be processed, ground and reprocessed in injection moulding procedures without changing the structure and characteristics of the material.
As part of this effort, the first practical experiment has conducted which proved that virgin HDPE can be recycled at least 10 times and can also be processed further under controlled conditions.
ESE product development and marketing director Udo Fröhlingsdorf said: “Decades of developments under production conditions have put us in the position to process and treat recycled material in such a way that the quality of the products is on a par with virgin material.
“The findings of this series of experiments now allow us to engage in more targeted research and to develop further future-oriented methods."
During the testing, ESE World, in cooperation with external research institutions, analyzed the material after each step using advanced methods.
The tests revealed that over the entire period of reuse, the injection moulding process and shredding of the plastics have no property-altering effects on the material, ESE said.
ESE said in a statement: “With the service life of containers being around 10 to 20 years, this result means that the availability of material for sustainable production from the same recycled plastic is secured for at least 100 to 200 years.”
