Biochar that proves itself.
SaveAsBiochar records every truck, weighment, reactor run and bag as it happens, so your credits hold up in any audit.
How it works

Records shown are examples.

It starts with what the harvest leaves behind.

Every load keeps its origin.
Each receipt is tied to the supplier and the source it came from.

Charred, not burned.
In the reactor, heat with little air drives off the gases and leaves solid carbon behind.

Every bag weighed and tagged.
Cooled biochar is bagged, weighed and tagged, so each bag carries its own history.

One plant. One unbroken record.
From the field to the bag, every step is linked and ready for an auditor.

Look inside the reactor.
A continuous gasifier, the kind small plants run. Turn it, open it, and tap any part to see what it does and what gets recorded.
What it does
Recorded

Feed hopper
Corn cobs wait here. The hopper sits on a load cell, so every kilo fed in is weighed.
Recorded Feed weight, continuously
Bucket elevator
Lifts the feed to the top of the reactor.
Recorded Running time
Double airlock
Two gates open in turn, so feed goes in and air stays out.
Recorded Gate cycles
Reactor, top zone
About 500 °C. The feed dries and begins to char.
Recorded Temperature, every minute
Reactor, centre zone
About 600 °C. Gases leave the feed and the carbon stays.
Recorded Temperature, every minute
Reactor, bottom zone
About 750 °C, the hottest zone, where air is let in.
Recorded Temperature, every minute
Air blowers
Feed just enough air to hold the heat, never enough to burn it all.
Recorded Blower speed
Rotating grate
Turns slowly and lets finished char fall through.
Recorded Grate speed
Collection and discharge screws
Carry the hot biochar out while water cools it.
Recorded Biochar out, and its temperature
Water cooling
Pumps and a cooling tower keep the discharge cool.
Recorded Water in and out temperatures
Gas outlet and cyclone
Gas leaves here and drops most of its dust.
Recorded Gas temperature
Control panel
A touchscreen and six temperature controllers run the plant.
Recorded Read straight from the panel. Nobody retypes a number.
A carbon credit pays for carbon kept out of the sky. It only pays when you can prove it.
200+
Puro.earth issues biochar credits as CORC200+: carbon stored for several centuries, well beyond 200 years.

Registries like Puro.earth ask where every load came from, how each batch was made and where every bag went. A gap in the records is a gap in the credits.
Built for the plant floor.

Works where the signal doesn’t.
Drivers and ground staff record on an Android phone. With no signal nothing is lost; it syncs when they are back in range.

Every number shows its working.
Net weights and totals show how they were worked out, so an auditor can check them in seconds.

Nothing is quietly changed.
A correction never overwrites. It becomes a new version, with who made it and when.

Ready for Puro.earth.
Evidence is organised the way the Puro Standard asks, from the field to the bag.
Made for the people who make biochar.
Plant owners.
Stop losing credits to paperwork. Your team records the work once, on their phones, and the file your auditor needs builds itself.
Credit buyers.
Trace every credit back to the truck, the reactor run and the bag it came from.
Auditors.
Follow the evidence in the order the work happened, with every change on the record.
