#WHEN_SHIT_STARTS_FLYING, FOLLOW THE CARBON.
Dr. Anju Sharma #MrsSustainability
Village gobar gas was a near-perfect local loop:
Dung ? Digester ? Cookstove ? Digestate ? Soil
Waste became energy. Nutrients stayed local. Almost nothing moved.
#IndustrialCBG changes the equation.
The moment a local manure loop becomes a centralised energy business, it acquires:
Aggregation ? Trucks ? Upgrading ? Compression ? Storage ? Distribution ? Digestate logistics
The chemistry is the same.
The carbon system is not.
#TheHiddenCarbon
Take a 100 t/day plant sourcing wet biomass over an average 50 km.
100 t ? 50 km = 5,000 tonne-km/day
At ~0.12 kg CO?e/tonne-km:
? ~220 t CO?e/year
from loaded inbound freight alone.
Not counted:
? Empty backhaul
? Digestate return
? Compression power
? CBG distribution
? Steel + concrete + plant equipment
And then comes #methane.
#Biogas/#biomethane systems can lose around 2?5.5% of #methane output across digestion, upgrading, storage & handling.
That can mean roughly:
1 t CH? produced ? ~0.5?1.5 t additional CO?e on a 100-year basis.
That is not an operational footnote.
It can materially erode the climate advantage before logistics, electricity & infrastructure even enter the ledger.
#TheStrategicBlindSpot
The atmosphere does not distinguish between methane from a gas field & methane from a cowshed.
It responds to the molecule.
That is why the global biomethane debate is already moving from:
Renewable origin ? Verified lifecycle performance
#EU, #UK, #US, #Denmark & #Brazil increasingly focus on some combination of:
Feedstock eligibility | lifecycle GHG thresholds | methane leakage | chain-of-custody | actual emissions avoided
India should be asking the same question.
Capturing manure that would otherwise decay anaerobically & emit methane can create real climate value.
But:
Long feedstock radius + wet-biomass trucking + residue removal + methane slip + compression energy ? automatically green
#PolicyInversion
If policy rewards:
Installed capacity + tonnes of CBG
the system optimises for volume.
If policy rewards:
Verified net CO?e avoided
the system optimises for:
? Methane leakage
? Feedstock radius
? Fossil logistics
? Genuine waste diversion
? Digestate return
? Lifecycle carbon integrity
That is the difference between a bioenergy programme & a decarbonisation programme.
The real #KPI should therefore be:
Net CO?e avoided / unit of useful energy
#Not merely tonnes of gas produced.
The full #CarbonLedger must include:
Feedstock km | methane slip | transport fuel | compression power | digestate fate | soil-carbon impact | infrastructure footprint | counterfactual emissions
As once policy rewards capacity before carbon performance, the pattern becomes predictable:
Build first ? Certify green ? Audit later.
So when shit starts flying across districts:
Follow the carbon not the certificate.
