The science of embers

So what exactly is biochar?

It isn't charcoal with a green label. It's a technically different product — and you can feel the difference on the grill, in the flavour and in the forest.

The process

Slow pyrolysis: wood transformed, not burned

Traditional charcoal is made in rudimentary kilns that burn part of the wood and leave residues behind. We use slow pyrolysis — controlled thermal decomposition, without oxygen.

Harvesting invasive acacia

We collect only acacia wood (dealbata and melanoxylon) from Portuguese forest-clearing operations — dense, high-energy raw material that would otherwise go to waste.

Controlled thermal transformation

The wood is heated without oxygen, at controlled temperature and time. All the toxic gases and harmful compounds accumulated by the tree are removed from the final product.

Solar energy and heat recovery

The process runs on solar energy and the heat generated is recovered and reused — minimum waste, minimum footprint.

Quality control

Screening that removes dust and fines, zero-moisture checks, and bagging in recycled, FSC®-certified packaging.

What this means for you

Less charcoal, more grilling

💶

It goes further

With higher calorific power you need 20–30% less charcoal per cook. A 15 dm³ bag equals ~5 kg of traditional charcoal.

🍽️

Clean flavour

No toxins, no strange smoke: the flavour is your fish and your meat — not the charcoal.
