In 1986, Marc Pena joined the company GILBERT PENA, which was managed by his father, a specialist in recycling and trading in non-ferrous metals.

In 1990, he took over the reins of the company and created the Pena Group. One business is responsible for the pursuit and diversification of the company’s traditional activity – this is PENA METALS (operating nationally and internationally). PENA ENVIRONMENT is dedicated to the collection, consolidation and recycling of hazardous and non-hazardous wastes (operating regionally).

In 2005, driven by the conviction that vast tonnages of non-hazardous wastes unnecessarily end up as landfill, he opened the CORIS substitute fuel production line on the Merignac site (33). SRF is used in cement works and industrial furnaces as a replacement for fossil fuels.

In 2007, Marc Pena turned his attention to deposition of household wastes, and developed the AROM technology for the recycling and recovery of 80% of our household refuse.

“Always finding a useful purpose for waste”


Holder of a Technical University Diploma in marketing and a Masters in business management (from Paris Sorbonne), Hugues Sandeau joined the company GILBERT PENA in 1988.

When the Pena Group was established, he was appointed as General Manager of the company PENA METALS, and later of PENA ENVIRONMENT.
