Zero Waste Scotland Welcomes Digestate and Compost Breakthrough

Zero Waste Scotland has welcomed last week’s announcement from Quality Meat Scotland (QMS) to declare digestate and compost by-products from anaerobic digestion as safe for farmers to use on crops.

With over 1.3m homes in Scotland benefiting from a food-waste collection – and many large business required by law to recycle food waste – the move will, according to officials at Zero Waste Scotland, help develop markets for compost and digestate products arising from the expansion of food waste collections.

Chief Executive Iain Gulland said: ‘The decision by QMS to permit the use of compost and fertiliser products derived from food waste is a breakthrough for Scotland.

‘Food and other organic wastes contain nutrients which are important to plant growth, so it’s appropriate they are returned to the soil when it’s safe and right to do so.

‘We’ve worked extensively with the organics recycling sector over several years to accumulate evidence on outputs from compost or anaerobic digestion (AD) facilities.

‘It is now clear that these products, when made to a quality specification, do not pose a risk to human or animal health.’

Used to treat household food waste, farmyard manures and energy crops, AD involves breaking down biodegradable material using micro-organisms in the absence of oxygen.

The process provides a source of renewable energy and produces a rich bio-fertiliser, which is high in valuable nutrients such as nitrogen, phosphorus and other elements required for healthy plant growth and fertile soil.
