Kierrätysvirta

Kierrätysvirta is a Finnish term that translates to "recycling stream" or "recycling flow." It refers to the process and infrastructure involved in collecting, sorting, and processing recyclable materials. This encompasses a wide range of materials, including paper, cardboard, glass, metal, plastics, and organic waste, which are then transformed into new products, thereby reducing the need for virgin resources and minimizing waste sent to landfills.

The concept of kierrätysvirta is central to waste management strategies in Finland and many other countries aiming for a circular economy. Effective kierrätysvirta relies on public participation through proper waste separation at households and businesses, as well as efficient collection systems. Municipalities and private companies often manage these operations, ensuring that collected materials are transported to specialized sorting facilities.

At these facilities, advanced technologies are used to separate different types of recyclables. For instance, optical sorters can identify plastics by their polymer type, while magnetic separators extract ferrous metals. Once sorted, these materials are baled or processed further before being sent to manufacturers for remanufacturing. The success of kierrätysvirta is measured by recycling rates and the environmental benefits achieved, such as reduced greenhouse gas emissions and energy savings.
