Solution/technology

Plastic Recycling Amsterdam receives plastic from numerous parties, such as waste processing companies and municipalities. We use the Magnetic Density Separation technology to process this waste.

This goes as follows:

  • We wash the plastic and grind it into smaller pieces (these pieces are also called flakes)
  • These pieces end up in the MDS, which contains the magnetic fluid
  • In the magnetic fluid, a magnet is used to create a density gradient field. This creates a different density at different heights in the MDS
  • Then, the particles flow through this density field
  • Each type of plastic has its own density and sinks or floats to a specific level
  • At the end of the bath, all plastic flakes flow to the different compartments.
  • The pieces of plastic are now divided into different types of plastic, with a purity of up to over 99%

In the past 1.5 years, this technology has been applied successfully and commercially at a 100% scale to different flows and for different types of customers, in a Dutch factory. Companies send us the plastic particles as washed flakes. Plastic Recycling Amsterdam works mostly with original plastic waste mixes. So in this case, we also handle the reception, cleaning, and grinding into flakes for the MDS.

Since we handle all activities (from opening the plastic waste bag to developing a high-quality end product) in one factory, we save a lot of money on transportation and we reduce our CO2 emissions. And the waste – the percentage of plastic waste that cannot be reused after processing – is also significantly less compared to other recycling processes. The quality and purity of the final product can be compared to virgin (new) plastic, which means that less new plastic has to be produced.

The process

 

Less CO2 emissions
The process is cost efficient
Higher product purity of the recycled plastic
Much less waste than the 40% in the current process
