First Scientific Tests Prove HDPE’S Recycling Properties

ESE World has carried out the first practical experiment to demonstrate that HDPE can be recycled at least 10 times and further processed under controlled conditions. The company has been the leader in the use of recycled plastics for the manufacture of containers for waste and recyclables for over 30 years. Its advanced procedures and processes in the cleaning, additives and processing of the material enables ESE to make products from recycled plastics with the same quality as virgin material. However, one question that has remained unanswered until now was how often HDPE can be processed, ground and reprocessed in injection moulding procedures without fundamentally changing the structure and characteristics of the material. ESE therefore established a controlled experimental model at its production facility that enabled virgin HDPE to be reused 10 times. After each step the material was analysed in cooperation with external research institutions using state-of-the-art methods. The project was led by ESE’s plastics specialist and scientist Jeanett Köhn, PhD. The test demonstrated for the first time that the injection moulding process and shredding of the plastics have, in principle, no property-altering effects on the material over this entire period of reuse. 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. Udo Fröhlingsdorf, Director of Product Development & Marketing at ESE, is very pleased with the test results. “Decades of developments under production conditions have put us in the position to process and treat recycled material in such a...

Scotland’s Zero Waste approach highlights the increasing need for managing waste as effectively as possible – but it also brings into focus the increasing pressures on managing resources as efficiently as we can. “When the time comes for a similar approach across the rest of the UK, we need to be sure we can store and move waste without a huge demand on already stretched manufacturing resources, “says ESE World Managing Director Dave Hughes. “Having been involved in the recycling of more than four million plastic wheeled bins, we can now produce containers manufactured from 100% recycled material.” They are robust and durable containers, which meet all the guidelines of the RAL GZ-951/1 quality mark, the most rigorous and demanding standard applied to these products. “The level of recycled content can be specified by customers and is also dependent on colour requirements,” he adds. “The important feature is that we’re able to maximise recycled content through design and process experience, not just through availability of material.” “Just because you have the materials to make a bin doesn’t mean that you can produce a container which will be as good.” “We aim use the resources entrusted to us in a sustainable way. We’re not just aware of our responsibilities towards protecting natural resources, we’ve changed the way we work so that we meet those responsibilities full on.” “When we produce new plastic bins and containers we aim for CO2 reduction through the whole process; from raw materials, through manufacturing, and transport…and back...
