Abstract:
According to the Waste Act, a waste is something that the owner wants to get rid of, or the removal of which is necessary from the point of view of caring for a healthy environment. The term secondary raw material is not defined in the legislation, but it is commonly used in practice [1]. It is a raw material that is obtained from waste by various procedures, i.e. it is created by human activity, which distinguishes it from primary raw material that was created by natural processes without human intervention. The condition for treating treated waste to be called a secondary raw material is that there is a demand for it and that it is traded on the producer's side.
Foundry production is accompanied by the creation of a large amount of waste. At each stage of casting production, different types of waste are generated in different quantities. The largest amount of waste is used foundry sand, followed by various fine-grained wastes that arise during melting, preparation of moulding materials, production of moulds and cores, and during processing and blasting of castings [2]. Another important foundry waste is the slag that is created during melting in any furnace equipment.
The current situation in Europe is "pushing" the producers of these wastes to reduce their amount. One possibility is waste recycling [3,4]. Most foundry waste cannot be directly recycled, but with certain modifications, they become secondary raw materials that can be used primarily in construction, agriculture, and partially also in foundries.
This contribution analyses the waste generated in the foundry process and points out the possibilities of their treatment and further use.
