NRAs 2015 Best Energy-from-Waste Initiative: Finalists

Bygrave Lodge anaerobic digestion plant

Biogen – Bygrave Lodge anaerobic digestion plant (above)

The award-winning AD plant at Bygrave Lodge Farm, near Baldock in Hertfordshire, has been developed as part of Biogen’s strategy to build a network of green energy plants across the UK. The plant processes domestic and commercial food waste to generate renewable energy, and provides a sustainable food waste treatment solution in the local area. The Bygrave Lodge plant utilises advanced AD technology, and has been recognised by the CEEQUAL Assessment and Awards Scheme. 

Bio Collectors – taking London’s waste and recycling it in London

Bio Collectors is the only food waste recycling business in London taking the capital’s waste and recycling it in London. The company has been involved with the development of the food waste recycling technology for five years, and its process turns food waste into agricultural fertiliser, electricity and biomethane. It operates a closed loop cycle with 100% landfill diversion.

GENeco

In less than a year, GENeco has completed the UK’s first commercial gas-to-grid supply of enriched biomethane produced from food waste, commercial liquid waste and domestic sewage. The plant, situated at Bristol Sewage Treatment Works, uses AD to extract the remaining energy from organic matter contained in the waste in the form of biogas. The biomethane is also being used in vehicles, and is under trial using the Bio-Bus, the UK’s first passenger bus to be fuelled from food waste and sewage.   

FCC Environment – Lincolnshire energy-from-waste facility (below)

Lincolnshire EfW facility

Lincolnshire’s EfW facility is an excellent example of how to deliver a large, complex and contentious scheme on time and within budget. It was achieved by Lincolnshire County Council taking an unusual approach to the treatment of risks that the industry normally transfers to the private sector. It remains the only EfW project to be fully funded by a local authority in the UK. The plant had diverted 187,486 tonnes of waste from landfill by the end of 2014, and saved £14.9m in landfill tax by the end of the year. 

Viridor – Ardley energy recovery facility

Viridor’s £200m ERF in Ardley, near Bicester, uses state-of-theart technology to safely transform 300,000 tonnes of residual waste into enough electricity to power over 38,000 homes. With an R1 efficiency status, the ERF is CHP-ready and exports 26MW to the national grid, diverting more than 95% of inputs away from landfill. It resulted in the creation of around 550 construction jobs and a further 40 permanent operational roles.

ReFood – Widnes gas-to-grid AD facility (below)

ReFood Widnes is the first AD gas-to-grid plant of its kind in Europe specifically developed to process waste from any point in the food chain and recycle it into renewable energy for use in homes across the region.

With the ultimate goal of eliminating food waste from landfill, the resulting digestate can be used as nutrient-rich fertiliser for local farms, enabling the food chain to close the loop. ReFood is part of Saria.  

Norfolk County Council, the Environment Agency, Landfill Systems and Cleanergy – new energy from old landfills (below)

In 2014, Norfolk became the first council in the UK to deploy an innovative system to generate energy from the low-grade methane at a closed landfill site. The initiative has been a great success, and provides a model for other local authorities which have to tackle the issue of toxic methane being generated from closed landfill sites.
