A CBG plant that fails IS 16087:2025 on H₂S or methane, or loses too much methane in its off-gas, can often be retrofitted. This article explains how.

Spent wash biogas can carry up to 3 percent H₂S by volume. This article explains why a sugar mill CBG plant needs a bulk desulphurisation stage first.

This article explains how enclosed ground flares work, how temperature, residence time and turndown are set, and what data a manufacturer needs.

Biomethane has no single global specification. This article sets RNG, biomethane and CBG limits side by side and shows what each asks of the gas train.

Sewage digester gas carries the heaviest contaminant load of any RNG feedstock. This article sets out what EN 16723, IS 16087 and gas tariffs ask of it.

Excavating old landfills releases trapped gas and odour, and gas control has to move with the works. This article compares mobile flares and aeration.

Sewage digester gas carries the heaviest contaminant load of any CBG feedstock. This article sets out what IS 16087:2025 asks of the conditioning train.

India's CBG policy has moved from ambition to funded mandate. This article traces the GOBARdhan relaunch, the blending obligation and IS 16087:2025.

In CBG and RNG projects the handovers between vendors fail more often than the equipment. This article explains why one gas-train partner changes that.

This article explains why a thermal oxidiser and an enclosed ground flare need to run as one interlocked system, using a plastic pyrolysis plant.

Flare gas recovery captures routine flare gas for reuse as fuel while the flare stays as the safety device. This article covers where it applies and pays.

Thermal oxidisers suit steady process exhausts and enclosed flares suit variable flows and relief gas. This article explains when to use each.

This guide explains the main H₂S scrubber types for biogas and wastewater gas and the gas loads, costs and site conditions that suit each one.

Open flares and enclosed flares differ in visibility, emissions, noise and suitability for different gas streams. This guide sets out the differences.

This article compares direct-fired, recuperative and regenerative thermal oxidisers on heat recovery, fuel use, cost and the duty each suits best.
