About Powerhouse Energy Group Plc

Powerhouse Energy has developed a process technology which can utilise waste
plastic, end-of-life-tyres, and other waste streams to convert them
efficiently and economically into syngas from which valuable products such as
chemical precursors, hydrogen, electricity, heat and other industrial products
may be derived. PHE's process produces low levels of safe residues and
requires a small operating footprint, making it suitable for deployment at
enterprise and community level.
