What IS 16087 actually means for a CBG project sponsor

IS 16087 is the Bureau of Indian Standards specification for biogas (biomethane). Oil-marketing company offtake materials and GAIL’s published quality table for the 2016 edition include methane at a minimum of 90 percent by volume, carbon dioxide at a maximum of 4 percent, combined CO₂+N₂+O₂ at a maximum of 10 percent, oxygen at a maximum of 0.5 percent, total sulphur including H₂S at a maximum of 20 mg/m³, and moisture at a maximum of 5 mg/m³.

PNGRB documents in 2026 also cite IS 16087:2025 for injection into pipelines and city-gas networks, alongside network codes. The stricter of the applicable codes applies. A website should not freeze a company claim to a single year of the standard.

For a sponsor this is not trivia. Upgrading technology, pretreatment, analyzer specification, odorisation and compression all have to live inside that envelope if the offtake is Indian commercial CBG. SATAT-era cascade delivery to retail outlets is commonly compressed to 250 bar.

Saimona will not publish a plant as “IS 16087 compliant” without a defined offtake specification and measured quality plan for that project.
