kierrätysvaiheen

Kierrätysvaiheen refers to the stage of recycling where collected materials are processed for reuse. This involves several distinct steps, beginning with the sorting of collected waste. Different types of materials, such as paper, plastic, glass, and metal, are separated to ensure efficient processing and to maintain the purity of the recycled output. This sorting can be done manually or through automated systems utilizing optical scanners, magnets, and eddy currents.

Following sorting, the separated materials undergo cleaning to remove contaminants like food residue, labels, or adhesives. This cleaning is crucial for producing high-quality recycled products. Once cleaned, the materials are typically processed into a more manageable form. For example, plastics may be shredded or melted, paper baled, and glass crushed into cullet. Metals are often melted down.

The processed materials are then sent to manufacturers who use them as raw materials in the production of new goods. This circular process reduces the need for virgin resources, conserves energy, and minimizes landfill waste. The effectiveness of the kierrätysvaiheen is dependent on the quality of collection, the efficiency of sorting and cleaning, and the demand for recycled materials in the manufacturing sector. Public participation and technological advancements play significant roles in optimizing this critical stage of the waste management cycle.
