("Powerhouse" or the "Company")

Major New Horizon Europe Project

​

Powerhouse Energy Group (AIM: PHE), a company focused on the conversion of non-recyclable waste into low carbon energy alongside its revenue-generating engineering consultancy division Engsolve, is delighted to announce that it will be participating in new Horizon Europe Innovation Action under HORIZON-CL6-2025-01-CIRCBIO-01: "JUST-CIRCLE - Measuring and Advancing Circular Business Models for a Fair and Sustainable Transition", which is being led by Brunel Business School at Brunel University of London.

Coordinated by Brunel University of London, JUST-CIRCLE brings together 14 partners across nine countries to examine how circular business models can be designed, measured, and implemented in ways that are environmentally sustainable, socially fair, financially credible, and practically adoptable

The project will develop and test new frameworks for sustainability accounting, lifecycle impact assessment, and circular business-model innovation, working closely with industry, social-economy, and academic partners across sectors including agriculture, waste-to-energy, food services, and circular water reuse.

With a total consortium value of approximately €5.85 million and just under €5 million in EU funding, JUST-CIRCLE will support the transition towards more evidence-based, inclusive, and scalable circular economy practices.  Under the terms of the consortium, this is a 70% grant funded project of which PHE is  expected to receive  approximately £225k for the utilisation of its technology.

The Brunel Business School academic team is led by Dr Grigorios Theodosopoulos and includes Dr Marios Samdanis, Dr Lefteris Kretsos and Professor Danae Manika.

The first kick off meeting will be hosted at Brunel University on the 10^th and 11^th of June.

The other partners involved are:

·    Brunel University

·    SPI - Sociedade Portuguesa de Inovação

·    ANALISIS-DSC

·    The American College of Greece / Alba Graduate Business School

·    Greener than Green Technologies SA

Paul Emmitt, CEO of Powerhouse Energy Group, commented:

"We are delighted to be part of this consortium and working with the team.  This project is undoubtedly asking some very significant questions which need to be looked at and addressed; with the findings certainly expected to shape how we approached sustainability and the circular economy in the future. Not only is this a prestigious opportunity utilising our technology to provide key data to the consortium, but it is also a 70% grant funded project of which PHE will receive circa £225k.

We look forward to providing further updates on this exciting initiative as it progresses."
