Algae & Algae Biomethane Project

Biomethane • CO₂ Recovery • Enriched Digestate

Algae & Algae Società Agricola r.l. is developing a permitted circular-infrastructure project in Mesagne, Brindisi, Italy. The platform will convert agricultural and agro-industrial resources into pipeline-quality biomethane, recovered and liquefied carbon dioxide, and enriched digestate for productive agricultural use.

Project at a glance

• 32 hectares — owned project site in Mesagne, with the SNAM high-pressure gas pipeline crossing the property.
• 13 million Sm³/year — saleable biomethane at steady state.
• 18,000 tonnes/year — recovered and liquefied CO₂.
• 50,000 tonnes/year — enriched digestate / biofertiliser.
• €52.1 million — total project cost.
• 15 years — GSE operating-support period.

Project readiness

Autorizzazione Unica was obtained on 1 August 2024 following multi-department review. Executed feedstock arrangements cover the initial operating period, 100% of saleable biomethane is covered by a 15-year offtake agreement signed in October 2025, and a five-year renewable offtake agreement signed in May 2026 covers 100% of planned recovered CO₂ production.

An independent technical review issued by RINA on 21 August 2026 supports validation of the design, construction and operating assumptions.

Expected delivery timetable

• 1 January 2027: expected start of construction.
• Q1 2028: expected start of production.
• Early Q3 2028: expected full production following commissioning and ramp-up.
