CCm Technologies has developed a method of producing fertiliser and soil conditioner through the use of captured carbon dioxide from industrial power generators. The first full-scale fertiliser manufacturing plant has been successfully commissioned at CCm's Technology Centre in Swindon before its deployment to Viridor’s multi-waste site in Somerset. The technology highlights include:

• Transformation of 6,500 tonnes of waste Anaerobic Digestate cake into approx. 13,000 tonnes of high-grade compound fertiliser.
• Exothermic heat (1.98 GJ (551kWh) of thermal energy per tonne of carbon dioxide; high storage density at 200kWh/m3) from the process will supply Viridor’s regulatory pasteurisation step, freeing up valuable bio-gas to be sent to the grid.
• Capture and utilisation of carbon dioxide being emitted from Viridor’s bio-gas generators.
• 90% reduction in the carbon footprint when compared with traditional fertiliser manufacturing techniques.
• Application extensions have been developed for the sewage sector allowing for the capture of the waste Phosphorous and Ammonia, currently being discharged into watercourses, to be integrated CCm’s upgrading of the bio-solids into fertiliser. 
• This sustainable technology is stand-alone financial viable and is not reliant on government subsidies. The base case internal rates of returns (IRRs) for the process generate between 15-18%.
• Industry matching fertiliser following years of agricultural trials at the Royal Agricultural University & Velcourt.

CCm's heat recovery and storage units store thermal energy within a chemical reaction, much like a battery and releases it rapidly as the chemical reaction starts. The technology highlights include:

• 1.98GJ (551kWh) of thermal energy per tonne of carbon dioxide - and importantly, like batteries, the storage density of our materials is high at 200kWh/m3
• System can be recharged with either heat or electrical energy. 
• Heat from produced at 125DegC but re-charged using much lower temperatures, generally around 50DegC to 80DegC utilising a lower grade source and over a longer period of time.
