From Zero Waste Scotland today:
Findings from the Scottish anaerobic digestion (AD) and biogas sector survey 2017, as well as the Scottish composting sector survey 2017, show a significant rise in the amount of recycled food waste. Approximately 158,500 tonnes of household and commercial solid food waste was collected in 2017, compared with the 2013 figure of 111,500 tonnes. People and businesses are increasingly doing their bit to help the planet as the additional increase in food waste sent for recycling (47,000 tonnes) has prevented the release of 41,500 tonnes of carbon dioxide equivalent being released into the atmosphere, as it has been saved from the general waste bin. The figure is the equivalent of taking 22,004 cars off the road in the UK for a year or driving around the world 5829 times. Producing electricity, heat and gas from food waste through AD allows us to capture the energy stored in our food that would otherwise be sent to landfill or incinerated. Using this waste helps to reduce our reliance on fossil fuels.
