Biochar 101 - Reduce Carbon Emissions?

The importance of soil and why the solution to climate change might be right under our feet

By David Dodge and Duncan Kinney March 15, 2015

In the movie Interstellar, Matthew McConaughey’s character has a line that’s stuck with me: “We used to look up at the sky and wonder at our place in the stars. Now we just look down and worry about our place in the dirt.”

Soil is the thin crust of organic matter that supports all life on this planet. And if we treat it right it might just be solution to one of our greatest problems – climate change. There is more carbon in the soil than in the atmosphere and all of plant and animal life combined. By returning carbon to the soil on a massive scale we could have a solution to climate change under our feet.

Biochar

That’s where a small industrial plant in Craik, Saskatchewan comes in. Titan Clean Energy Projects has their processing facility in this unlikely place and it’s here where they make biochar.

Biochar is an extremely inert form of carbon made by heating up wood waste and organic material to 600 degrees Celsius in an enclosed space without the presence of oxygen in a process called pyrolysis. By returning this biochar to the soil on a large scale we could have a legitimate climate solution.

“We know that Canada is not meeting its carbon reduction targets. And this is one opportunity to provide a very big bang for the buck to reduce carbon emissions,” says Jamie Bakos, the CEO of Titan.

But despite the fact that the world’s cultivated soils have lost 50 to 70 per cent of their carbon stock and that anthropogenic climate change threatens irreversible and dangerous impacts, there is still no meaningful price on carbon or a long-term strategy to reduce the amount of carbon in the atmosphere.

Without that in place Titan is focusing on other markets for its product. Look at biochar under a microscope and you can see the myriad pores and twists and folds. If you were to take one gram and it spread it out it would cover an area larger than a tennis court. And all that surface area gives good bacteria a place to call home.

“We're just starting to see the payoff of some of our product development with the biochar in remediation, reclamation, water treatment, and possibly even animal nutrition,” says Bakos.

It’s hard work developing a market for a new product from scratch but Titan is making a go of it. They have retail products for sale — things like biochar for gardeners, fire logs and bulk absorbents.

But the biggest seller for them right now is in soil and water remediation.

“We have a product that helps break down hydrocarbons, helps plants deal with alkalinity and salt. Our next biggest use is for water purification and water treatment and that includes both drinking water and waste water. So, we're using the biochar along with plants in a hydrosoil mixture to basically clean up waste water from the mining industry,” says Bakos.
