The Altpreneur knowledge centre
Practical knowledge for complex plant decisions.
Technical guides, worked examples, original policy sources and documented plant experience. Read by topic or by the decision in front of you.
Start with the fundamentals
Understand the gas balance before the production promise.
Raw biogas, methane recovery and saleable CBG describe different parts of the process. Our guide connects the units, operating hours and measurement boundaries.

A reading path for your project stage
| If you are... | Start by understanding... | Then examine... |
|---|---|---|
| Assessing an opportunity | Feedstock quality, seasonal supply and sample evidence | Feasibility, gas offtake and project sensitivities |
| Reviewing the design | Working volume, HRT, organic load and operating hours | Equipment interfaces, storage and acceptance tests |
| Running a facility | Time-aligned feed, gas and equipment data | Losses, repeat failures and measured corrective actions |
| Preparing a financing case | Scope boundaries, cash timing and conditional support | Downside cases, buyer terms and operating assumptions |
How to use the research
Source links support the technical discussion. Worked examples are labelled and should be recalculated using your project's data. International references offer context; local conditions and applicable Indian requirements govern the actual project.
How news is maintained
Policy and technology updates retain their original source dates. Research is screened for relevance and reviewed before publication. A new article is added when there is a meaningful development, without redating old reports to make the section appear active.
