Powerhouse Energy Group PLC (AIM:PHE)’s European patent application, 'Method and Apparatus for the Treatment of Waste Material', has been "allowed", the waste-to-gas group said in a statement.
The process now moves forward towards a full grant of a patent, which will also require payment of the applicable fee.
Powerhouse (PHE) added the patent relates to control of the heating of the waste within the thermal conversion chamber to allow the optimal amount of syngas to be produced.
UK and Ireland would be covered by the patent as well as Europe, the statement said.
Discussions with a number of clients across numerous industries over the use of the technology are underway, it added.
Keith Riley, PHE’s acting chief executive, commented: "This is an important step for the company in establishing itself as a major developer within the waste processing sector.
"The patent application being allowed is a key step to having the patent fully granted, which adds value to what PHE can offer to its clients."
