Growth in anaerobic digestion is driving the organics recycling industry, according to WRAP, despite finding only one plant managing to sell the digestate that the process produces.
Figures from WRAP’s comprehensive survey of the organics industry in 2010 released this week, show the number of permitted AD sites leapt 182% from 17 to 48 in 2009.
Total input of organic waste processed by AD topped the one million tonnes mark for the first time in 2010.
In total the industry recycled 7.23m tonnes of organic material through AD and composting.
Composting inputs grew by 3.9% to 5.44 million tonnes, and 273,400 tonnes of organic waste fraction was processed by mechanical biological treatment plants.
Ian Wardle, head of organics at WRAP, said: “This study illustrates the significant and growing role of AD technologies, and of the market for AD digestate, across the UK. Since 2010 this growth has been given further impetus through strong support from all UK governments, and from WRAP’s support for the sector which includes the £10 million AD Loan Fund.”
