Waste is generated as a result of production processes and the implementation of various works. According to the legislation of the Russian Federation, waste is classified according to hazard classes (classes I – V). Our factory generates waste of all hazard classes and we divide them into the following groups: hazardous, non-hazardous and packaging waste. Hazardous waste includes used mercury lamps (hazard class I), batteries (hazard class II), mineral oils (hazard class III) and materials contaminated with chemical substances (hazard class IV). Non-hazardous waste includes plastic waste, polyurethane foam, manufacturing defects (hazard class V). Packaging waste is allocated separately. It includes cardboard, polyethylene film and wooden pallets (hazard class V).
