Carbon removal methods

Biomass or biowaste heated in the absence of oxygen (a thermochemical conversion named pyrolysis). A very stable, solid form of carbon that can endure in soil for hundreds or thousands of years. Multiple uses at potentially industrial volumes, for example, as greenhouse additive, in soil regeneration and in stormwater or wastewater treatment.

Biochar activities can also

The storage of woody biomass in conditions that prevent decomposition and maintain carbon locked away for at least 100 years. A new innovative approach to immobilise carbon, that offers a unique opportunity for large-scale, affordable carbon removal.

Terrestrial Storage of Biomass activities can also

By reacting with CO2, these materials mineralize and form carbonates, thereby trapping and storing the carbon dioxide for geological timespans. Offering a pathway to transform the environmental impact of an entire industry while utilizing industrial byproducts and waste materials such as steel slag mine tailings and alkaline waters.

Carbonated materials activities can also

A process that accelerates natural rock weathering that usually takes thousands of years. Rock weathering begins with the reaction between water, carbon dioxide and silicate rocks which breaks down the rock to then form biocarbonates, a durable for of carbon. When spread on agricultural land, the rock can be highly beneficial and can increase crop yields.

Enhanced rock weathering activities can also

Carbon capture processes such as Direct Air Capture (DAC) and Bio-energy Carbon Capture Storage (BECCS) with geological storage, such as direct injection of CO2 into deep geological formations. Puro.earth methodology only allows the capture of CO2 directly from the air or from biogenic sources, not from fossil fuels. A highly scalable and permanent carbon removal pathway.

BECCS activities can also
