Terrapreta Tech
About Us
Our goal is to securely return carbon to the earth and leave behind a legacy of productive soil.
Our mission is to remove carbon dioxide from the atmosphere at an industrial capacity with the aim to reach 300 ppm CO2 before the end of the century, while making the agricultural land climate-resilient and fertile enough to feed over 8 billion people on this planet.
We also work to stop global climate change with a huge number of partners around the world. Our technology is able to go beyond net zero, producing net negative emissions, by naturally taking carbon dioxide out of the atmosphere through biomass production and then permanently storing it hundreds of meters below the Earth’s surface.
Addressing climate concerns and the food chalenge
One of the strategies TERREPRETA TECH uses is an industrial symbiosis strategy that begins with exploiting carbon-rich agricultural leftovers to make pellets. The pellets are subsequently carbonized, releasing and using heat. After carbonization, a carbon-rich material called terrapreta is produced. In essence, terrapreta is embodied carbon dioxide that is used to improve agricultural soils’ capacity to hold nutrients, so promoting food production that is climate-friendly. Since we can remove the actual carbon atom from the carbon cycle without having to store the entire CO2 molecule underground, we believe it to be the most promising carbontech option.
Globally, soil quality is declining. Up to 75% of the bonded carbon once found in soils has been lost. Crop yield and soil productivity are impacted by this. Agricultural soils can be improved by adding terrapreta. Because this carbon is incorporated into the soil, it is stable and serves as both a carbon sink and a matrix for storing moisture, nutrients, and microorganisms.
Photosynthesis is nature’s most effective method of removing CO2 from the atmosphere. Biomass is created from CO2. The biomass is turned into syngas (mostly methane, carbon monoxide, and hydrogen) by a low-oxygen pyrolysis process, which is then burned for heating. terrapreta is a new fraction that results from the process. The carbon atoms in the terrapreta are thus bonded from the ambient CO2, which is actually carbon that has been emitted in the past.
Up to 6000 years old terrapreta charcoal deposits have been discovered in Amazonia, up to 9500 years old in Guyana (Hammond et al., 2007), and up to 23,000 years old in Costa Rica (Titiz & Sanford, 2007).
