Biochar: Burying Carbon and Building Climate Resilience in South African Farms

Biochar for Soil Health and Carbon Sequestration

• 💡 Biochar, an activated carbon made from waste wood, is being adopted by farmers in South Africa to restore degraded soil.
• 🌱 Farmers like Yako Ace are observing that increased carbon in the soil leads to better water retention capability, resulting in healthier crops.
• 🔑 Biochar actively restores the soil and replenishes micronutrients lost over generations of farming, offering an alternative to purely chemical fertilizers.

The Biochar Production Process

• 🏭 Companies like Absorb Carbon in Johannesburg produce biochar using pyrolysis furnaces.
• 🔥 Waste wood chips are fed into furnaces heated to around 1,110°F and then further activated at up to 1,650°F.

Climate Impact of Biochar

• 🌍 Biochar is highlighted as a sustainable practice that can make a significant impact on climate change at scale.
• ⏳ The activated carbon locks away carbon from the soil for centuries, effectively burying it and contributing to carbon sequestration efforts.
