ReFood orders second gas-to-grid plant from Greenlane

- repeat business - the best of all testimonials

- Greenlane’s water-wash process meets the extra demands of producing pipeline quality biomethane from food waste

Greenlane Biogas has received a multi-million pound contract from ReFood Ltd, part of the SARIA Group, to supply and install a ‘Totara’ biogas-to-biomethane upgrading plant at a new food waste processing site under development in Dagenham, Essex, UK.

The contract is the second to be placed by ReFood for Greenlane’s water-wash upgrading equipment. The system has many similarities to the first one, operating on ReFood’s site in Widnes since summer 2014. From its earliest days that plant was dubbed as one of the most efficient of its type in Europe.

The ‘Totara’ unit in Dagenham will output up to 2000 Nm3/hr of biomethane to the national gas grid. 

Greenlane’s Director of Engineering, Glenn Mercer says: 

“The ability of the Greenlane water-wash system to treat the high levels of contaminants, inherent in the biogas from most food waste, is a prime reason to be confident that the Dagenham project will match and even exceed the operating and commercial benefits to the customer of the successful Widnes plant. 

“We are delighted to be working with ReFood once again”, adds Mr Mercer. “It speaks for itself as a good testimonial for our technology and service.”

For ReFood, Commercial Director, Philip Simpson says:

“We are proud of our food waste processing site at Widnes and the Greenlane upgrading system within it. We are looking forward to achieving the same success with our Dagenham project.”

Greenlane Biogas is an established worldwide leader in biogas upgrading, with over 100 sites operating in over 20 countries. With more than 20 years’ experience designing and installing biogas upgrading plants, Greenlane’s process development and technical experience is unrivalled.  It is a member company of Pressure Technologies plc, which is listed on AIM of the London Stock Exchange.

Greenlane Biogas upgraders operational around the world are in Brazil, Canada, China, Denmark, Finland, France, Germany, Iceland, Holland, Japan, New Zealand, Norway, South Korea, Spain, Sweden, the UK, and the United States. 

The two largest biogas upgrading plants in the world at Güstrow, Germany, and Montreal, Canada, use Greenlane's water wash technology.

The technology employed is efficient and environmentally friendly, processing and purifying the raw biogas produced from wastewater treatment and the anaerobic digestion of a wide range of organic waste materials, including food waste. When upgraded, the resulting biomethane (or renewable natural gas) has very similar properties to the natural gas used in gas networks or as a vehicle fuel. Many Greenlane projects have gas-to-grid or pipeline connection as their objective.

The company has recently expanded adding two further technical processes for upgrading biogas, Membrane and Pressure Swing Absorption (PSA), to its world leading water wash technology. This now gives Greenlane a unique position in a growing market, enabling it to provide a solution for all biogas upgrading projects regardless of site location or feedstock type. It also allows it to mix technologies to produce the best solutions for the customer.


Greenlane Biogas was formed in November 2008 under the brand name Chesterfield Biogas, following the signing of a co-operation agreement with Greenlane® Biogas, the world leader in biogas upgrading. It gave exclusive rights to market, manufacture and maintain Greenlane® equipment in the UK and Eire and saw the UK's first biogas upgrader supplying biomethane to the national grid installed at a Thames Water site in Didcot in 2010.

In October 2014, Pressure Technologies acquired the Greenlane® business, giving the division, and the Group, a worldwide presence in the rapidly growing biogas upgrading market.  Chesterfield BioGas was subsequently renamed Greenlane Biogas UK. Sheffield, UK now forms the headquarters for the worldwide operation. The business operates in three geographical regions; North and South America and China, serviced out of Vancouver, Canada; Europe, serviced out of Sheffield, UK; and South East Asia and Australasia serviced out of Auckland, New Zealand.
