A site driven by experienced partners
working as a team
The Solidia Biogaz platform is the result of a joint approach involving major actors in the fields of R&D, methanisation, and industrial gas infrastructure operation. They are all committed to exploiting the biogas sector as a means of achieving a sustainable energy transition.
INSA Toulouse: operation and scientific support
The training and research institute plays a role in national and territorial scientific research strategies. It tries out solutions for tomorrow, in response to the major scientific, social and environmental challenges facing us today. Energy transition through the development of the renewable energy sector is one arm of its strategy. To achieve its objectives, INSA capitalises on the work of researchers in its own laboratories, including the TBI (Toulouse Biotechnology Institute) and its technological research centres, including the CRITT GPTE (regional centre for innovation and technology transfer in process engineering and environmental technologies). The latter, specialising in R&D in process engineering and environmental technologies for over 20 years, works in partnership with businesses in the field of production process industrialisation.
Solidia Biogaz is led by INSA Toulouse. The institute is responsible for the technical gas equipment, and for managing the site’s operations. With overall management of the pilot plants on the platform, it ensures they have all the resources they need for their tests. It can also contribute to process experimentation and lend a wealth of scientific and technical skills.
About INSA Toulouse:
INSA is a public institution for higher education and research. Two INSA Toulouse entities are involved in the SOLIDIA project: Toulouse Biotechnology Institute (TBI) and the CRITT Génie des Procédés et Technologies Environnementales (CRITT GPTE).
TBI is a research laboratory, a joint unit under the supervision of INSA Toulouse, INRAE and CNRS. Its innovation is positioned at the interface between life sciences and process sciences. TBI brings its scientific expertise to the SOLIDIA platform through the involvement of INSA’s research professors and researchers from INRAE’s TRANSFORM department.
The CRITT GPTE is a development department of INSA in the process engineering sector, providing the link between the industrial sector and technology transfer. On the SOLIDIA platform, it is responsible for the integration of semi-industrial pilots, along with the managing and conducting tests.

Teréga: structural and industrial expertise
Fully engaged in the energy transition, Teréga is a major actor in the development of solutions using renewably sourced and low-carbon gases. Its aim: to accelerate transformation in the industrial sector and change in the territories, against the backdrop of European environmental challenges. It is therefore involved in the deployment and exploitation of biomethane and hydrogen.
Recognised for its expertise in the construction and operation of gas infrastructures, Teréga assisted in the design of the Solidia Biogaz platform, and in the design and realisation of the transport network for the different gases used on the site. It supports INSA in selecting its industrial equipment and identifying needs when the installation of a new pilot plant involves specific preparations to be implemented. It also helps the platform to grow its skill set, ensuring the industrial conformity of every process hosted there, by managing the safety aspects of the site as a whole and the pilots hosted there.
About Teréga :
Established in South-West France, at the crossroads between major European gas flows, Teréga has exercised exceptional expertise for 80 years in the development of gas transport and storage infrastructures. It operates over 5,000 km of pipelines and 2 underground storage reservoirs representing 15.6% of the French gas transport grid and 25% of national storage capacity respectively. In 2023, the company generated revenues of €494m and it has more than 640 employees.

Cler Verts: support for biogas resources
As a major actor in the circular economy in the Toulouse region, Cler Verts is an acknowledged specialist in the collection and repurposing of all types of organic waste: wood, plant waste and biowaste. It is also a company committed to the energy transition, and sensitive to innovations promoting the biogas sector. It is therefore involved in a number of research projects linked to methanisation.
Cler Verts is an industrial actor producing biogas from a methanisation unit. The Solidia platform, installed a stone’s throw away, benefits from its proximity to sources of the raw resources it needs to operate. Cler Verts is the partner that guarantees the production of raw biogas and ensures it is transported to the platform.
About Cler Verts :
Established in Occitanie in 2003, Cler Verts is an acknowledged specialist in the collection and repurposing of all types of organic waste: wood, plant waste and biowaste. As the creator of the first multi-purpose platform in France, bringing together all the tools for repurposing organic matter on a single site (wood fuel, wood waste, composting, methanisation), the company has developed real mastery of operations, alongside formidable technical expertise. Cler Verts repurposes more than 16,000 tonnes of biowaste (into thermal energy, electricity and fertilisers), and produces more than 2,200,000 Nm3 of biogas annually.

The Solidia Biogaz platform is also supported by…
The Occitanie/Pyrénées Méditerranée region, acting for the sustainable development of its territory, its economic development and energy transition. Solidia Biogaz is one of the projects it supports and subsidises. Through its financial support the platform came into being, and can now host pilot plants for the biomethane sector.
