Topic of the practice


Good Practice Information

The Bio Mass Central is a boiler for district heating which comes from and still is a private initiative by a local entrepreneur, also active in her original landscaping business. Together with the municipality of Sittard-Geleen and other local companies the landscaping offers most of the biomass required for the central. Green waste is being offered to the central daily where it is stored open air. After crushing, the material is shoveled to a shelter from where an automated transporting system carries it to the oven. What follows is an Organic Rankine Cycle (named for its use of an organic, high molecular mass fluid with a liquid-vapor phase change, or boiling point, occurring at a lower temperature than the water-steam phase change. The fluid allows Rankine cycle heat recovery from lower temperature sources such as industrial waste heat, geothermal heat, solar ponds etc. The low-temperature heat is converted into useful work, that can itself be converted into electricity). The generated energy directly goes in and through the existing grid. Whereas it took quite some effort to get a deal fixed with the existing energy supplier (one of three major suppliers in the Netherlands), partners found themselves lucky that a cogeneration central still had to be built nearby, making a deal worthwhile for the national supplier, offering a major saving in not having to invest in a new one now. The pricing agreed upon for household was and still is basically the same as the traditional supply, although now a whole neighborhood enjoys the sustainable warming of their houses.

Evidence of success

Due to partnership, public investment only amounted to 100,000 euros. Sustainable heating for a whole neighbourhood (1,100 homes). Long-term solution for handling green waste (18,000tonnes p.a.), saving 3.4million m3 of natural gas, 5.6million KG of CO2.
