Manufacturing activities cause various wastes. These are divided into two main categories: hazardous and non-hazardous wastes. Hazardous wastes include cutting fluids, various types of waste oil, paints and solvents, oily wastes, solid wastes, etc. Non-hazardous wastes include scrap metal, metal swarf, waste plastics, waste wood, domestic waste, cardboard, and paper waste. All Wärtsilä companies sort their waste according to local municipal regulations. Generally speaking, the main sorting categories are waste to be incinerated, waste for landfills, and waste for recycling.

Waste management in Wärtsilä has four aims, in their order of priority to:

  1. Reduce the amount of waste generated in processes
  2. Use waste as a material
  3. Use waste as energy
  4. Dispose of waste in an environmentally sound way
