VAR on site

VAR processes between 900,000 and 1,000,000 tons of waste yearly. Underneath a list of the different activities can be found. The recycling- and processing activities are carried out by divisions of VAR. These are:

• VAR Biogeen, composting;
• VAR Biogeen, biomass;
• VAR Sorteren, sorting of industrial waste and building and demolition waste;
• VAR Mineralen, recycling of building and demolition waste;
• VAR Mineralen, dumping of residue streams and cleaning of old landfill sites;
• VAR Mineralen, washing and recycling of contaminated soil;
• VAR Energie, production of secondary fuels.

VAR Engineering is the development and engineering department of VAR and is responsible for the design and building of all installations and techniques applied by VAR.

Composting

Division:

Type of waste:       

85% organic fraction from household waste (obtained from separate collection) / 15% biowaste

In operation since, In 1989 VAR Biogeen started with composting. In 1993 the existing composting installation was built. 

End products:        

Production of compost: 80.000 tons per year. This compost is registered under the quality control marks “Keurcompost”, RAG and RHP. The compost is mainly sold in the highest market area; the soil industry.

200.000 tons per year

Type of waste:       

Waste streams which cannot be processed in a different way (contaminated soil, asbestos, sludge, etc.) A former council landfill, without ground protecting provisions, are cleaned by VAR Mineralen, dumping. Over 50% is recycled, the rest isdumped.

In operation since 1992

End products:         

The contaminated soil of the former landfill goes to the sand washer. Also the landfill produces biogas that is turned into electricity on the spot (approx. 700 kWh).

Details:                  

This is the first time that in the Netherlands a former landfill is dug up completely and selected. 

Production secondary fuels
