Scots are recycling more food waste than ever according to new reports published by Zero Waste Scotland.
A total of approximately 158,500 tonnes of household and commercial solid food waste was collected in 2017, compared with the 2013 figure of 111,500 tonnes.
The increase had prevented the equivalent of 41,500 tonnes of carbon dioxide being released into the atmosphere – the same as taking more than 22,000 cars off the roads for a year or driving around the world 5829 times.
The findings are from the Scottish anaerobic digestion (AD) and biogas sector survey 2017, as well as the Scottish composting sector survey 2017.
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.
The rise has been helped by the introduction of the Waste (Scotland) Regulations 2012 compelling businesses to recycle food waste. As of 2016, Scottish businesses producing more than 5kg of food waste per week have been required to present food waste separately for collection.
The increase has also been supported by a growth in the availability of food recycling facilities to Scottish households via their local council, 80% of Scottish households now have access to food waste recycling.
Scotland will have one of the most ambitious climate change laws in the world after committing to a target of net-zero emissions by 2045.
Previous research from Zero Waste Scotland warns that food waste is worse than plastic for climate change. Food waste is a greater cause of global warming because of all the resources and energy that goes into growing and making the food in the first place. If wasted food is then sent to landfill, the impacts are even worse as this produces and emits methane, one of the most damaging greenhouse gases. In the short-term, methane is many times worse than carbon dioxide.
Iain Gulland, Chief Executive of Zero Waste Scotland, said:
“Scotland should be proud, the recycling of more food waste into sustainable energy is an incredible achievement. The rise in recycled food waste is welcome news for Scotland’s economy and for the planet. When we waste food, we also waste the resources that went into growing, processing, transporting and packaging it, so it is hugely important that we use what we have. Of course, some food waste is inevitable – we can’t escape waste of items like fruit and vegetable peel.
“This result is fantastic, but think of all the energy that can be produced from the rest of our unavoidable food waste. We are living through a climate emergency and individuals can have a great impact without even leaving the kitchen by simply using their food waste caddy.”
