Kierrätysbiojätteeksi

Kierrätysbiojäte refers to organic waste that is collected separately for recycling, typically through composting or anaerobic digestion. This category encompasses food scraps, garden waste, and other biodegradable materials that can be processed to create valuable resources like compost or biogas. The primary goal of kierrätysbiojäte collection is to divert organic waste from landfills, where it would decompose anaerobically, producing methane, a potent greenhouse gas.

Proper separation of kierrätysbiojäte is crucial. Common items included are fruit and vegetable peels, coffee grounds, tea bags, eggshells, bread, and cooked food leftovers. Garden waste such as leaves, grass clippings, and small plant trimmings are also typically accepted. However, materials like plastic bags, glass, metal, and non-biodegradable packaging should not be placed in the kierrätysbiojäte bin. Some regions may have specific guidelines regarding items like dairy products, meat, or bones, so it is important to consult local waste management regulations.

The collected kierrätysbiojäte is then transported to processing facilities. In composting, the organic matter is broken down by microorganisms in the presence of oxygen, producing a nutrient-rich soil amendment. Anaerobic digestion involves the breakdown of organic material in the absence of oxygen, generating biogas, which can be used as an energy source, and digestate, a liquid or solid residue that can also be used as fertilizer. This process contributes to a more circular economy by turning waste into useful products.
