Feed the rumen better.
Everything else follows.
Carbon-Kai is a daily feed supplement engineered for ruminal efficiency — made from New Zealand pine and blended minerals, cooked and quenched into a solid, granular additive. It helps cows turn more of what they eat into milk instead of belching it away: more volume, healthier herds, and over 40% less methane, almost as a side effect.
Cooked from NZ pine, ready to feed — not a liquid.
The payoff shows up before the emissions report does
Methane isn't just a gas cows burp out — it's energy the animal never gets to use. Carbon-Kai is built to recover that energy first. The climate benefit comes along for the ride.
More milk, better milk
Redirecting energy away from methane shows up in the vat — trials on related carbon technologies have recorded gains in milk volume alongside increases in milk fat and protein.
A healthier herd
Carbon-Kai's surfaces bind toxins, mycotoxins and heavy metals before they're absorbed — supporting gut, liver and immune health, with farmers reporting fewer drenches.
Over 40% less methane
Cows belch out 95% of the methane they make, wasting up to 12% of their feed energy in the process. Carbon-Kai changes the rumen chemistry behind that waste.
Good for the whole farm
Most of what a cow eats passes through into manure. Carbon-Kai keeps working there — cutting ammonia and nitrous oxide losses, then locking carbon into the soil and recycling mineralised nitrogen.
Carbon Coated Minerals, not off-the-shelf biochar
Standard biochar varies wildly — different feedstocks, temperatures, and heat residence times mean no two biochars behave alike, which is why so many biochar feed trials have gone nowhere, often delivering poor scientific results. Carbon-Kai's purposeful mineral blend is engineered into the pine before pyrolysis, targeting the rumen specifically rather than hoping a generic char happens to work.
“Carbon-Kai was born as a carrot, not a stick — a way to help farmers avoid a government methane tax, not a way to enforce one.”
Raymond Dobbe started Carbon-Kai after watching a proposed emissions levy threaten the farmers he worked alongside. The product exists to make the sustainable choice the profitable one — not to mandate it.
