Abstract [en]

Landfilling and waste incineration are two major waste management options. However, some wastes can,due to their carbon content,be unsuitable for neither of these systems. Therefore, there is aneed for methods to remove organic carbon from wastes. One of these wastesis the construction and demolition fines. In this paper, we investigate using water for separating the waste by density, to see if this is a suitable method for separating carbon-containingmaterials, both in lab and field scale tests. Results show that halfof the carbon (measured as volatile solids) can be separated. However, this method cannot be said to reliably produce a sink fraction that is suitable for landfilling, as it still contains too much organic materials.
