Biomethane production from waste using proprietary technology
About GMT
GMT Biogas builds, owns, and operates biogas plants that convert organic waste into carbon-negative biomethane, a renewable natural gas. The company utilizes a proprietary Plug Flow Reactor (PFR) technology, which it began focusing on in 2011 after years of working with traditional anaerobic digestion systems. This PFR technology is presented as a more efficient method for producing biomethane, maximizing output and achieving high operational availability.
The company's history in refining this technology has led to the design and construction of over 40 biomethane plants, ranging from small-scale projects to large gas-to-grid facilities. The business model involves turning animal and food production waste into a sustainable energy source, which helps businesses reduce emissions and move away from fossil fuels. Their plants are scalable, with energy outputs ranging from 80kW to over 10MW. The produced biomethane is injected into the national gas grid, and the process also yields a nutrient-rich biofertiliser.
The leadership team includes Gianluca Greenaway as Founder & CEO, who has 16 years of experience in anaerobic digestion and renewable energy. His background in chemical engineering and as a commodities trader for Cargill and Glencore informs the company's strategic growth. Philip Greenaway, the CTO, brings 22 years of experience in the field, having been involved in the creation of 47 AD plants and playing a key role in developing PFR technology in the UK. Pankaj Patel serves as the CFO, contributing his global experience in engineering, construction, and renewable energy to manage the company's financial strategy and growth.
