📖 Explanation:

What is Enhanced Weathering?

Enhanced Weathering is a natural climate solution, where the natural breakdown of certain rocks is accelerated to remove CO₂ from the atmosphere. This process happens naturally over thousands of years, but with crushed olivine and regular rain & irrigation water, the process can be speed up significantly — helping to fight climate change.

Why Olivine?

Olivine is a green silicate mineral that reacts easily with CO₂ and water. When olivine is spread over soil, sports fields, golf courses, or farmland, rainwater starts a simple chemical reaction:

💧 Water (H₂O) + ☁️ CO₂ from the air + 🪨 Olivine (Mg₂SiO₄)
➡️ Forms stable magnesium carbonate (MgCO₃) and silica (SiO₂), locking away CO₂ permanently.

✅ “1 tonne of olivine permanently removes 1 tonne of CO₂ from the atmosphere.”

How It Works (step-by-step)

1️ Crush Olivine into sand-sized particles (more surface = faster reaction).
2️ Spread Olivine Sand onto soil or turf.
3️ Rain and Irrigation water soaks into the sand, carrying atmospheric CO₂ into the soil.
4️ The water, CO₂, and olivine react — creating harmless carbonates (which stay in the soil) and silica    (which supports plant growth).
5️ Result = CO₂ removed from the air + healthier soil + long-term carbon storage

🌿 Bonus Benefits

✅ Improves soil structure
✅ Provides magnesium and silica for plants

✅ Helps balance soil pH (reducing acidity)
✅ Perfect for golf courses, sports fields, agriculture, and landscaping
✅ Contributes to climate-neutral projects

Summary
