One of the country's largest paper recyclers has lambasted local authorities that operate commingled schemes.
Aylesford Newsprint commercial manager Chris White said the increase of recycled materials being collected together had led to a fall in the quality of waste paper his company, which produces 1% of the planet's newsprint, receives.
White said: "We are getting more and more glass with our paper that comes from commingled schemes. It may be the cheapest way of collecting, but it makes sorting more expensive."
White added that he hoped the publicly available specification for waste paper would improve the quality of feed when the Waste and Resources Action Programme launch it at the end of March.
