-Precious metal recycling is nowadays closely related to the protection of the environment. It is integrated into a complex network of processes that benefit the clean supply of water and protection of the air quality. The wastewater streams generated during refining processes are treated by special processes which remove hazardous components. High efficiency wet scrubbing and filtration of exhaust air is employed in all stages of the metal recycling processes.

 Melting costs are only charged for re-meltable scrap and are based on the gross weight of scrap delivered, as well as on the type of precious metal to be recovered.

 Fees for the cost of content analysis vary by the type of precious metal and the form of the sample. Ash samples require significantly more work than pure metallic materials due to their high content of mineral substances.

 This amount contains the costs for transforming the refined metals into the required grade of purity, and also the cost to convert the end metal product into a commercially re-usable form such as for example ingots or granulate.

+Processing scrap, generated for example during contact manufacturing, usually consists of meltable material. Since refining costs are calculated based on gross scrap weight, the gain achieved through refining is highly dependent on the precious metal content and the current market value of the respective precious metal.
 Minimizing stamping scrap should therefore be considered during the design of contact parts right from the beginning. Unavoidable precious metal containing scrap should be strictly separated from stamping scrap of base metals. It is also recommended to separate scrap by the types of precious metal contained as well as by base materials.
-During shipping of refining scrap all regulatory laws must be followed, including declarations for the content of goods, transportation, and the intended disposal of residues of the base materials.
