Bio-waste is made up of discarded plant and animal residues, and includes garden/park and food waste. Between 118 and 138 million tonnes of bio-waste is generated across the EU every year, but less than 40% is currently recycled into useable products.
Recycling bio-waste is central to Europe's developing circular economy, of which composting and anaerobic digestion are both proven techniques. Together, they help:
- reduce the environmetal impacts of landfilling/incineration;
- return organic matter to soils - this helps maintain/restore soil quality and sequester carbon;
- produce bio-based product, such as compost, biogas, peat substitutes, fibers and chemicals; and
- recycle plant nutrients such as nitrogen and phosphorus.
