Industrial Ecology is concerned with the integration of existing industrial sites with heat hub of Warmtebedrijf Rotterdam. The industrial sites are Meneba, a grain processing plant, and RWZI Dokhaven, a waste water treatment plant.
For feasible integration of existing industrial sources with the waste heat transportation structure, new business models need to be developed.
These projects will result in a reduction of CO2-emission, NOx– emission and a higher energy efficiency.
Meneba is located nearby the heat hub of Warmtebedrijf Rotterdam.
Currently the total heat demand of Meneba is supplied by a steam boiler, including the heat demand of activities with lower temperature requirements. The aim of the case is to use a maximum of waste heat in stead of steam, by connecting the plant to the waste heat transport infrastructure of Warmtebedrijf Rotterdam, specific the heat hub. The total demand for waste heat is between 20,000 GJ and 40,000 GJ per year.
RWZI Dokhaven is located nearby the heat hub of Warmtebedrijf Rotterdam.
The sludge of waste water is converted by fermentation into e.g. biogas. The biogas is fuel for the CHP which produces electricity and heat. Now that the existing CHP is nearing the end of its lifecycle, the owner of the plant intends to reinvest in a new CHP. The aim of this case is to feed the heat from the new CHP into the waste heat transportation infrastructure of Warmtebedrijf Rotterdam, by developing a connection between de CHP and the waste heat transport infrastructure of Warmtebedrijf Rotterdam to the heat hub. The heat hub acts as a distribution station to the southern and northern parts of Rotterdam.
As a result of technical developments, the heat production in the data centre will rise. Mechanical chillers in the data centre are used for cooling. As a part of the CELSIUS project, the possibilities for integration with the waste heat transport infrastructure for cooling demand will be explored. In this case absorption cooling can be used to replace the electrical chillers, or when the cooling capacity of the data centre must be increased because it’s expanding. The data centre, located 200 meters from the waste heat transport infrastructure in the south of Rotterdam and a few kilometres from the heat hub-area, will be used as a theoretical demonstrator within the CELSIUS project.
