DMT has a long history in treating biogas. Since the founding of the company by Mr Dirske in 1987, a number of different types of biogas treatment installations has been installed, these include biogas dryers, chemical desulphurisation, biological desulphurisation and upgrading units.

Currently DMT employs 30 people with each employee believing in a future of renewable energy, whilst focusing on their goal, playing a crucial role in the development of renewable energy business by applying new technologies and implementing smart and simple solutions.

They currently have two biogas upgrading technologies in their program. One system is based on the high pressure water scrubbing; the DMT Carborex® PWS and the other technology is based on membrane separation; the DMT Carborex® MS.

The DMT Carborex® is the most economical, flexible and easy to operate. The advantages of this system are:

  • Most economical technology
  • Flexible capacity from 0-100%
  • Compact and small footprint
  • Easy to operate
  • Less civil / ground works
  • Low energy cost
  • More output due to less variance in outlet quality

In collaboration with their UK partner, Heat and Power Services, DMT have successfully installed 5 plants across the UK since 2012:

Rainbarrow Farm – Poundbury

The first commercial biogas to grid plant in the UK was built by DMT, commissioned in September of 2012 and opened by Prince Charles in November 2012. Since then more than 8.000.000 m³ of biomethane have been fed to the gas to grid.

Apsley Farm – Andover

The largest membrane upgrading plant in the UK, two MS1000 systems working in partnership allow the site to upgrade up to 2000m³/hr of raw biogas into biomethane for grid injection. The system was installed and commissioned in late 2013, converting gas created from agricultural products.

Wkye Farm – Champflower

Installed in late 2014, the system is specified to treat 1400m³/hr of biogas created from industrial food production, specifically whey and cheese waste, alongside agricultural waste, for injection to the national grid.

Mitcham – London

Situated in the UKs capital, collected food waste from local area is processed and turned into approximately 1000m³/hr of raw biogas that is processed through the MS1000 system. The system was installed and commissioned in late 2014.


Located on an old pig farm, the equipment was installed and commissioned in late 2014. The MS1000 plant processes 1000m³/hr of raw biogas created from a mixture of different agricultural feedstock.
