Paper Round moves to Anaerobic Digestion - Blog

Monday 30th September 2013

Paper Round is now processing food waste in an even more sustainable manner. We have switched from composting food waste to sending it to an Anaerobic Digestion (AD) facility.

Paper Round is constantly reviewing the treatment methods for the materials we collect to make sure we are providing the most sustainable solution. Latest research revealed AD is now environmentally preferable to composting and has become the Government’s preferred option for food waste treatment. In fact each tonne of food waste recycled by AD prevents 905 kg of CO² equivalent (which would have been released from sending it to landfill) from entering the atmosphere.

For that reason Paper Round has now partnered with BiogenGreenfinch, an expert Anaerobic Digestion (AD) company who convert food waste into biogas and liquid biofertiliser. The plant generates enough energy to power 3,600 homes and produces 35,000 tonnes of a superior liquid biofertiliser annually.

What is AD?

AD is a biological process which uses naturally occurring microorganisms in a sealed chamber to break down organic matter into a valuable fertiliser and a methane-rich biogas. A combined heat and power (CHP) engine is used to convert the biogas into a clean supply of electricity and heat. This heat is reused within the AD plant and the electricity enters the National Grid as a totally clean source of renewable energy. The nutrient-rich bio-fertiliser which is produced is then used for arable framing. This type of sustainable fertiliser is less intensive to produce and also reduces our reliance on fossil fuel based fertilisers.
