Jätejalostus

Jätejalostus, often translated as waste processing or waste refining, refers to the series of treatments applied to waste materials to reduce their environmental impact, recover valuable resources, and prepare them for disposal or reuse. This encompasses a wide range of techniques, from simple sorting and separation to complex chemical and biological processes. The primary goals of jätejalostus are to minimize the volume of waste sent to landfills, prevent pollution of soil, water, and air, and to extract materials that can be reintegrated into the economy.

Common methods of jätejalostus include mechanical-biological treatment (MBT), which combines physical sorting with biological degradation processes like composting or anaerobic digestion. Incineration with energy recovery is another significant approach, where waste is burned at high temperatures to generate electricity or heat, while also significantly reducing the waste volume. Recycling, a crucial component of jätejalostus, involves collecting, sorting, and reprocessing waste materials like paper, plastic, glass, and metal into new products. Hazardous waste requires specialized treatment to neutralize its harmful properties before disposal. The specific methods employed in jätejalostus are often dictated by the type of waste, local regulations, and the availability of technology and infrastructure. Effective jätejalostus is a cornerstone of sustainable waste management and the circular economy.
