Waste to Energy is known for utilising residual or non-recyclable waste for producing energy products such as heat and electricity. However, other products such as secondary raw materials can also recovered. This is recovered from the Incineration Bottom Ash (IBA) which consists of minerals and ferrous and non-ferrous metals such as aluminium, copper, and even gold. Bottom Ash can be used in several ways - building aggregates, production of glass, brick making, noise reduction barriers etc. This contributes to the circular economy. These materials indicate important Green House Gas (GHG) emissions savings. The recovery of metals alone saves approximately 60kg of CO2 per ton of waste treated.
