Wijster

The integrated waste processing plant at the Wijster location has been up and running since 1996.The plant consists of three parallel processing lines. It has an annual processing capacity of 800,000 tons.

Recycling

In the separation plant we first divide all of the presented remnant waste into sub-streams. All sorts of materials that are suitable for recycling are taken out. We extract materials such as metals and plastics as a raw material from the waste.

Materials recycling

 

Wijster has a unique integrated pre‐treatment and sorting activity. This allows us to separate out materials like metals, paper, plastics and ‘wet organics’ from the RDF stream before it goes into the incinerator. By doing so, we can maximise resource output and increase processing capacity compared to a stand-alone  EfW plants where basically all the waste is incinerated as it is comes. We have called this integrated facility EfW 2.0 as we believe it represents the future of EfW.

Our separation plant uses modern technologies such as foil separators and infrared equipment to extract plastic packaging materials from the remnant waste. These raw materials are subsequently sorted into plastics mono-streams in our own sorting facility.

Green gas and plastics

We process the organic wet fraction in our specialised anaerobic digestion plant. This plant processes biogas that we upgrade to green gas: sustainable gas with the quality of natural gas. This gas goes to the regional natural gas network.

Alternative fuel

There are also huge ‘vacuum cleaners’ that extract a mixture of unrecyclable paper and plastic from the waste. This is used as an alternative fuel, mainly in Germany and Scandinavia, at power plants and in the cement and chalk industry.
