AGROGAZ generates Renewable Natural Gas (RNG) from forages (energy crops). This development is 20 years old in Europe, but is new in tropical regions where, nevertheless, we generate higher gas yields at lower costs, using high-yield grass as feedstock. Gas production is around 10.000 m3 CH4 per hectare per year.

Biodigesters can be in "metal tanks" or "on-ground tanks (lagoon type)", depending on the size, topography, water table, and available land.

AGROGAZ is a partnership between BIOTEC and SAUTER-biogas of Germany. BIOTEC (www.bio-tec.net), has been a pioneer in the biogas sector in the tropics since 1984. AGROGAZ S.A.S. (www.agrogaz.com), based in Cali, is the representative of this technology in Colombia.
