Enhanced Weathering (EW)

---

While Enhanced Weathering is a carbon capture technique that accelerates the natural weathering process of rocks to remove carbon dioxide (CO₂) from the atmosphere - it is important here to discuss Enhanced Silicate Weathering.

 sequestAIR utilizes Enhanced silicate weathering (ESW) which is a carbon dioxide removal (CDR) strategy that accelerates natural geological weathering by using finely crushed silicate rocks (e.g., olivine) in the creation of our patented sequestering device.  Through innovative design we increase the surface area of the silicate, allowing it to accelerate chemical reactions with water, air and CO2,effectively removing carbon from the atmosphere 

Unlike traditional ESW, sequestAIR does not look to reduce emissions from ambient air, but from the exact point of emissions from home heating.  This is just one of many ways that we accelerate the take-up of carbon through the ESW process

Olivine is a magnesium-iron silicate mineral commonly found in volcanic rocks. Over geological time, when olivine is exposed to:

• CO₂ 
• Water 
• Oxygen
   

it slowly reacts and breaks down.  During this process, CO₂ from the air or water is converted into dissolved bicarbonate or solid carbonate minerals, which effectively removes carbon from the atmosphere.

 Advantages of utilizing Olivine

•  Very abundant globally

•  Reacts faster than many other silicate minerals

•  Provides long‑term carbon storage

•  Major deposits exist in Norway, Oman, the United States, and Canada. 

CO₂ Capture Potential of Olivine

•  Typical estimates:

•  1 ton of olivine can capture ~0.8–1.25 tons of CO₂

•  Often simplified as ~1 ton olivine → ~1 ton CO₂

•  Actual capture depends on mineral composition and reaction completion.
