CBG process
How organic material becomes a fuel specification
This is the industry sequence used to brief sponsors. It is not a patented Saimona process, and not every block is used on every project.
From feedstock to dispatch
The graphic is the industry sequence used to brief a project. The paragraphs below explain what each block is for — and why not every plant uses every block.
Industry sequence
Feedstock is collected and pre-treated so it can be fed stably. Anaerobic digestion then produces raw biogas — typically a methane and carbon dioxide mixture with hydrogen sulphide, moisture and traces.
Gas cleaning removes contaminants that damage upgrading and compression equipment. Upgrading removes carbon dioxide so the gas can meet a biomethane specification such as the latest applicable IS 16087 in India.
The upgraded gas is dried, odorized where required, compressed, stored and dispatched — by cascade, dispenser, industrial pipe or, where permitted, injection into a gas network. Digestate is managed in parallel as slurry or organic manure.
Not every project uses every block. A plant with industrial offtake may never see a 250-bar cascade. A high-solids municipal feed may never see a classic wet CSTR. The sequence is a briefing tool. Saimona’s job is to decide which blocks this feedstock and this buyer actually need, then integrate them through partners.
