In plain terms

Waste becomes wealth. Smoke becomes soil.

What the Mina project actually does — and why it matters — explained simply, for farmers, families and neighbours.

Every harvest, Iloilo's rice mills and fields are left with mountains of rice husk and straw. Today, most of it is burned or left to rot — and as it does, it releases carbon dioxide and methane into the air. That pollution feeds the very climate change now hitting our farmers hardest: hotter weather, a stronger El Niño, less rain, and failing harvests.

We change that. We gather the husk and straw and heat it without flames, in a sealed rotary kiln — a process called pyrolysis. Instead of smoke, out comes Platinum BioChar: a clean, stable, charcoal-like material that holds the carbon instead of releasing it.

Returned to the fields, Platinum BioChar works like a sponge and a battery for the soil — holding water through dry spells, cutting the need for costly fertiliser, and helping rice grow better. And because the carbon is locked into the soil for hundreds of years, every tonne is a real, lasting removal of carbon from the air — which the world pays for as carbon credits.

And for the subsistence families who grow Iloilo's rice, that adds up to something rare — a meaningful, lasting rise in income: from selling the husk and straw they once burned, from richer harvests, and from a share in the value of the carbon they help remove.

The same waste that once harmed the air now feeds the soil, cools the planet, and lifts the incomes of the families who grow our rice.

The simple version

From burning waste to living soil

Today: waste & harm

Husk & straw burned or left to rot — releasing CO₂ & methane.

We collect it

Gathered from rice mills & farms nearby.

We bake it — no flames

Pyrolysis in a sealed rotary kiln.

Platinum BioChar

A clean, stable charcoal — carbon locked in.

Back to the soil

Holds water, feeds crops, stores carbon 200+ years.

What the farmer gets back
Holds water in dry spells Less costly fertiliser Bigger, healthier harvests Cleaner air — no open burning Carbon locked 200+ years A significant, lasting lift in income for subsistence farmers
Our community programme
Kababayan

Countrymen. Kin. Fellow travellers. In our tradition, kababayan is the whole village coming together to lift a neighbour — when a family moves their home, everyone carries it together. That is the spirit of the programme: farmers, families and partners lifting one another — from Mina, for the Philippines.

“Kababayan” — an original oil painting; a wedding gift from Maribeth de Montaigne to her husband David on their wedding day, 35 years ago.  ·  The programme is delivered with our independent non-profit partner, School Aid MTÜ.
