The circular economy aims to maintain resources in use for as long as possible by keeping their value and reducing environmental impacts. No waste is created as leftover materials are reused. The circular economy opens opportunities for business and growth through effective use of byproducts, cooperation, and new business models. The Ministry of Agriculture and Forestry promotes the circular economy through projects utilizing side streams from various sectors such as fisheries, forestry, and agriculture to produce new products and recycle nutrients.
