From Agrimagined to Agreality in Africa
Nature finds ways of directing resources to where they are needed most, but if your eyes are not tuned to see these processes, they get taken for granted. Bryan Ollier has spent years honing this observational skill and has gained many lessons of how the natural world shares its nutrients. His recent work has sought to take these lessons and use them to make agriculture work with these natural processes, rather than against them.
Ollier has been partnering with Joseph Kinuthia of Kenya through their organization Agrimagined since 2021 to find innovative ways to tackle the challenges that farmers face in rural Africa. The bulk of the work ...
New Campaign Supporting Project to Address Food Insecurity in Tanzania
In partnership with Engineers Without Borders Tanzania, RTE is raising funds to introduce rock dust and biochar to soils in the Kilimanjaro Region of Tanzania to improve soil fertility, crop yields, and income for farmers.
Rock Dust Is Effective to Fight Climate Change, University of Illinois Energy Farm Finds
A new field study led by University of Illinois researcher Ilsa Kantola demonstrates how we can use rock dust weathering to greatly enhance carbon dioxide removal from the atmosphere.
The Riches of Rock Dust, by the Get Real Alliance
The Get Real Alliance has released a documentary series covering topics from founder David Munson’s book Get Real: A Positive Solution to Climate Change. The eight episodes released so far describe the carbon cycle, biochar and rock dust, as well as issues related to grasslands, forests, oceans and more.
The Get Real Alliance explains their goals as follows: “The Get Real Alliance supports rock dust remineralization of soil and wetlands, biochar additions to soil for fertility and water retention, marine wetland restoration and overall agricultural changes.”

A Breakthrough in Verifying Carbon Dioxide Removal by Rock Dust Weathering
For over a billion years, rock weathering has played a central role in regulating Earth's climate. So what’s behind the rock-climate connection? It turns out...
Huplaso Grows: Natural Mineralizer from New Brunswick Quarry Making Inroads Across Canada, World
(Updated May 7, 2023)
Jean-Paul Dubé
The Huplaso quarry in Bathurst, New Brunswick, contains a rock that is rich in more than 57 minerals (macro, micro and trace elements) and is ideal for soil remineralization and organic plant growth.
“It increases about 27% the health of the plant,” said Stéphane Losier, business development director. He added that the product, made from ultramafic basalt-type volcanic rock dust, improves yields by more than 35%, balances pH and increases soil paramagnetism levels.
According to Jean-Paul Dubé, Huplaso’s North American sales manager, paramagnetism produces a potentially beneficial ...
Remineralization Pioneer David Yarrow on Transforming Soils to Transform Ourselves
There’s no doubt that the industrialization of agriculture has changed the world we live in. With the advent of chemical fertilizers and pesticides, ‘agribusiness’ is a commercial enterprise seeking to do what most businesses do — maximize profit. But soil isn’t a static input, a sterile medium, or an endless reservoir from which crops will always sprout. In fact, treating soil in this way is a fast-track to depleting it. Continuing down this path is not sustainable, and it’s becoming clearer that we must rethink the way this system works, and move forward in a regenerative, holistic way.
One of the pioneers of this ...
UNDO Matters: UK carbon removal company taking remineralization mainstream
The story of UNDO Carbon Removal began as the story of the Future Forest Company, says Jim Mann, cofounder and chief executive officer of both, with the former using enhanced weathering and the latter taking the reforestation route to ecological restoration in the United Kingdom. And so, UNDO spun out from Future Forest in mid-2022.
Jim Mann, cofounder and CEO of UNDO
“We were trying to move quickly with in-house rock weathering, trying to scale fast. Reforestation and ecological restoration are relatively slow processes. You might spend a year planning and then two years getting the appropriate permissions and signoffs from government ...

According to the Intergovernmental Panel on Climate Change (IPCC), without significant cuts in greenhouse gas emissions, the global temperature will increase by 3 to 4 degrees Celsius by the year 2100. This could have catastrophic consequences for human society. We are already living with the effects of the 1.1-degree increase that has occurred since the industrial revolution began around 1760. Major heat waves, wildfires, floods, and ...
