Aberdeen appoints contractor for AD facility

A contractor has been appointed to build an anaerobic digestion gas to grid plant in Aberdeen which will treat food waste from the city, as well as agricultural material.


Austrian-based AD specialist Thöni Industriebetriebe GmbH is to construct the anaerobic digestion gas to grid plant which will produce biogas for injection into the national grid, as part of a £12.7 million contract with Aberdeen city council, awarded last month.

Biogas produced from the AD facility will be fed into the energy centre at the multi-million-pound new TECA arena

The plant will process 81,000 tonnes of feedstock per annum, with 41,000 tonnes comprising organic waste collected from the region.

The biogas produced from the facility will be upgraded to biomethane and injected into the natural gas grid. It will then be piped to the onsite Energy Centre at the multi-million-pound new TECA arena. The plant is designed to produce 425m3/h of gas.

TECA is being developed beside Aberdeen International Airport, and the new city bypass. The 12,500-capacity main arena will host conferences, exhibitions and music concerts.

The AD plant is one of the income streams for the development, and will receive a subsidy from UK Government which is guaranteed for 20 years, in the form of the Renewable Heat Incentive, Aberdeen city council said.

Food waste

Food waste from Aberdeen city council residents is collected in caddies, and added to brown bins which collects food and garden waste. Brown bin collections are every fortnight in Aberdeen. The council also has communal food-only waste bins mostly in the city centre, and they collect around 1,500 tonnes per annum.

Aberdeen city council co-leader Councillor Jenny Laing said: “The AD plant project powering the TECA complex underpins the position of Aberdeen as a world-class city for energy and innovation and the centre as the place to see how energy, environment and business can be integrated on a truly significant scale.

“We are in the midst of the most important period of transformation Aberdeen has ever experienced including an increased focus on renewable energy sources.”

“We are in the midst of the most important period of transformation Aberdeen has ever experienced including an increased focus on renewable energy sources as part of our Regional Economic Strategy, and it’s fantastic that TECA can lead on that.”

Thöni is a family-owned company founded in 1964 and with headquarters located in Tyrol in Austria. The company said it has been building renewable energy facilities for more than 25 years. The company has been working closely with Target Renewables Ltd based in Ayr, Scotland, since 2013 and has built several digestion facilities in the UK, it says.

Robert Lackner of Thoeni said: “We’re really excited both about the project itself but also in being part of the story. Even more so, as this is part of show case for “the future of energy supply” in the middle of the centre of the fossil gas and oil industry.”

Robin Szmidt of Target Renewables said: “I’m looking forward to the project becoming not just an engineering success but also a success for the new AECC, the city, and the local community.”


TECA arena, conference centre and exhibition building is part of the new AECC project which includes two on-site hotels, an energy centre. The entire site is being built by Aberdeen city council along with development partner Henry Boot Developments (HBD), and main contractor Robertson Group.
