The type of feedstock to be used for CBG production and financial viability of a plantdepends on many factors like cost of input feedstock, location of plant, etc. As per SATAT scheme, the responsibility of setting up of CBG plant lies with the entrepreneur and therefore applicant is requested to assess CBG production and financial viability of its plant by itself. The following tentative yield of various feedstocks are normally considered as per discussion with various existing and proposed CBG Plants and various technology providers. However these are only directional in nature and actual yield may vary substantially depending on quality of feed stock
Following major approvals are required.However the list are not exhaustive and State / district Authorities may be approached for further clearances required (if any) Before constructing a new factory, several approvals are necessary to ensure compliance with various regulations. Firstly, if the land is non-industrial, it must be converted and registered as non-agricultural land. The District Industry Centre (DIC) requires registration as an MSME (Micro, Small & Medium Enterprises), though no further action is needed post-registration. Fire safety regulations necessitate obtaining a No Objection Certificate (NOC) before construction, a license after construction, and annual renewals thereafter.

CBG or Compressed Bio Gas consist of mainly methane (more than 90%) and other gasses like carbon dioxide (less than 4%), etc. CBG is produced by anaerobic digestion of biomass and waste sources like agricultural residue, cattle dung, sugarcane press mud, municipal solid waste, sewage treatment plant waste, etc. This Biogas can be purified to remove hydrogen sulphide (H2S), carbon dioxide (CO2), water vapor and when this purified biogas (methane content more than 90%) is compressed to maximum 250 bar and filled up in cascades (group of high pressure cyllinderical vessels) it is called Compressed Bio Gas or CBG
