Retina
Biomethane infrastructure designed around the agricultural supply chain.
Retina develops facilities that turn livestock effluent and agricultural by-products into biomethane for injection into the gas network.

FROM AGRICULTURAL RESIDUES TO GAS
Follow the production cycle
01
Agricultural inputs
The project starts with livestock and agricultural residues.
02
Biomethane
The facilities convert those inputs into renewable gas for injection into the grid.
03
Useful by-products
Retina’s model also envisages commercialising biogenic CO₂ and using digestate to produce organic soil improver.
A network of plant projects
Retina’s site provides individual project updates for locations including Velletri, Terracina and Pontinia. The company’s work covers design, construction and management of the infrastructure.
