Start with the installed base.
Know what exists, what functions, what failed and what it costs to repair.

What biogas needs after installation
Bangladesh knows how to install biogas plants. The harder work starts after handover: use, repairs, safety and a buyer for digestate. The next phase of finance should pay for proof that the system still works.

Core argument
A biogas plant is useful only if it keeps producing gas, can be repaired and leaves behind records of real use.
What has to hold
Keep the plant useful.
Before scale, check four records: asset, use, service and value.

Records before scale
Asset. Use. Service. Value.
What we learned
The unit is not enough.
- Asset file
- Household, GPS, installer, commissioning, safety and consent.
- Use record
- Gas use, fuel stacking, feedstock routine and household value.
- Repair log
- Fault, response, parts, downtime, repair cost and closure.
- Payment trail
- Digestate quantity, quality, buyer, invoice and payment.
Work in dense clusters.
Choose places with feedstock, water, roads, technicians and buyers.
Separate the products.
Wet slurry, compost, vermicompost, granules and Bio-CNG need different rules.
Pay after use is shown.
Link support to service, safety, use and documented household or market value.
Clear the rules first.
Map fertiliser, gas, safety and emissions requirements before capital moves.
Field evidence
Measure use, not presence.
Function
Check the plant at 6, 12 and 24 months.
Service
Record tickets, response time, parts and downtime.
Value
Track fuel savings, slurry use, sales and payments.
Market anchor
Digestate needs a buyer.
FSMV shows the field lesson: producers, quality support and buyers have to be organised together.
FSMV | Project-reported
Find the buyer first.
Promise digestate income only after standards, buyer commitments and payment records exist.
"Now we can sell it easily and earn cash in hand."

What should happen next
Go back to the field.
Before new money goes in, check what still works, why other plants stopped and what a viable cluster would cost.
Find the plants
- List every unit with household, location and installer.
- Mark it as working, damaged, idle or missing.
Ask why
- Check feedstock, water, user effort and repair history.
- Separate bad siting from fixable service gaps.
Follow the slurry
- Measure what is used, collected or sold.
- Record the buyer, price, quality and payment.
Make the call
- Expand only where use and service hold up.
- Repair, redesign or stop where they do not.
Evidence note
Say what is proven.
Public data, project material and proposed operating rules are kept distinct.
Priority data still missing
- Reconciled asset register with GPS, household, installer, commissioning and status fields.
- Current functionality and stove-use checks across 6, 12 and 24 months.
- Repair cost, service response and digestate payment records.
- Written regulatory path for fertiliser, gas, safety and emissions authorisation.
Supporting sources
Sources include public clean-cooking, livestock, finance and policy material plus project-supplied biogas, FSMV and Bio-CNG records. Project-reported figures are not treated as independently verified impact.
