Nowadays, recycling is a very often discussed topic though its realization varies. One way the recycled material has to be collected, subsequently sorted, melted, cast repeatedly and the casting has to be respectively machined. Otherwise given casting can be recycled by repair in a form of material adding. This way of repair is suitable, especially where the product of the casting is degraded due to material missing for example as a result of cavitation. This method not only saves the environment and lowers the cost of recycling, but is also very time and cost-effective.
