Plastics recycling: replacing raw materials with made-to-measure recompounds

High-quality recyclable plastics to customer specifications: Interseroh’s award-winning “Recycled-Resource” process closes the waste plastic loop – conserving valuable resources and protecting the environment. 

Experts for closed-loop resource recycling: our innovative Recycled-Resource process has perfected the compounding of waste plastics. At our plastic reprocessing plants – in Eisenhüttenstadt in Brandenburg, for example – we use waste packaging and production scrap to manufacture new, market-quality recycled plastic materials. 

Additionally, we combine our research and development activities in the field of plastics recycling in our centre of competence in Maribor, Slovenia. In March 2020 we received the official international accreditation. This makes our centre of competence the only recognized research institution in the EU specializing in the development and analysis of recycled plastics. It thus sets standards throughout Europe in the implementation of uniform quality standards.

Interseroh recycled plastics: high-quality and customer-specific solutions

Recythen and Procyclen – two strong recycled plastics

We source the raw materials for our two recycled plastic products from domestic-quality waste collection, which mostly consists of polyethylene (PE) and polypropylene (PP) packaging. Our granulate, Recythen, can be used for manufacturing products such as cable reels, garden furniture, drainage pipes and cable conduits.  

Procyclen is an award-winning, customisable “recompound”. By altering its formulation, Procyclen can be matched to customers’ exact requirements in terms of fluidity, stability, UV/thermal resistance and colouration. Just like a new, petroleum-based raw material, Procyclen is able to meet the same kinds of rigorous requirements for new products or packaging, and can also be used in injection moulding or extrusion processes.

Manufacturers using Recythen or Procyclen in their plastics products can apply for the “Blue Angel” eco-label – and thus acquire a key differentiator. 

Customer benefits from Recycled Resource:

  • Certified, reproducible material quality

  • Exact documentation of all material data

  • Upcycling and full compliance with the REACH Regulation

  • Technical support for production

  • Planning security and security of supply

  • An effective contribution to conserving resources and the environment

Saving the environment with Recythen and Procyclen 

With recycled plastics from Interseroh, you help conserve resources while also reducing greenhouse gas emissions: as shown in a recent study by Fraunhofer Institute UMSICHT, based on data from 2020, Procyclen and Recythen improve your environmental footprint.* 

If Recythen is used instead of primary plastic made from crude oil, 1,100 kg of greenhouse gases are saved per tonne – a 61 per cent reduction in climate-damaging emissions. Consumption of primary energy also falls by 22,254 kilowatt hours per tonne – equivalent to 14,836 loads of laundry.**

To the product data sheets

If Procyclen is used, 1,002 kg of greenhouse gases are saved per tonne (around 56 percent***) and primary energy savings are 21,199 kWh – around 14,133 loads of laundry. 

To the product data sheets

* A recent study by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT compared the production of primary granulates from crude oil with that of Recythen and Procyclen from recycled materials with respect to their primary energy usage and greenhouse gas balance. The calculation is based on the life cycle assessment environmental management standards IS0 14040 and 14044. The technologies compared reflected the latest state of the art. All results relate to a tonne of granulate.
** Assuming a consumption of 0.50 kWh per wash. This corresponds to energy efficiency class "A".
*** The slightly lower savings with Procyclen are a result of the additional materials used.

Increasingly eco-efficient and cost-effective

Impressive figures – and we are working hard on further improvements to these positive environmental effects: with the latest generation of Procyclen, greenhouse gas savings can now be as high as 50 per cent, since manufacturing now takes place in just a single process step and also requires less energy. This conserves resources and makes the process even more cost-effective. 

Technological Innovation

This all ist possible due to  the  innovtive cascade extrusion system COREMA®, which allows the manufacturing of customised recycling compounds for exceptionally high-quality applications in just one processing step. And this innovation is already award-winning: In April 2019, the PRSE Award in the category “Recycling Machinery Innovation of the Year” was given to the environmental services provider Interseroh and the technology manufacturer EREMA.

Award-winning performance

Interseroh’s plastics recycling has not only attracted an impressive and steadily growing number of manufacturers and dealers: our Recycled-Resource process and our Procyclen recycled plastic are already multiple award winners.
