The term 'magic dust' refers to crushed basalt, a volcanic rock that plays a significant role in carbon capture and agricultural enhancement. This innovative approach utilizes basalt to absorb carbon dioxide from the atmosphere while simultaneously improving crop growth through a process known as enhanced rock weathering.
Enhanced rock weathering is a method that accelerates a natural chemical reaction. When rainwater, which contains dissolved carbon dioxide, interacts with crushed basalt, a reaction occurs that solidifies the carbon. This process effectively removes carbon dioxide from the atmosphere, contributing to the reduction of greenhouse gas levels.
Beyond its carbon-capturing abilities, basalt is beneficial for crop production. Studies indicate that basalt not only enhances crop yields but also improves the quality of grazing land for livestock. The minerals found in basalt enrich the soil, fostering better plant growth and overall agricultural productivity.
The company 'Undo' plays a pivotal role in this initiative by supplying basalt to farmers at no cost, funded through the purchase of carbon credits. Major corporations such as British Airways, Microsoft, and McLaren Racing buy these credits as part of their efforts to offset carbon emissions, thereby supporting the spreading of basalt on farms.
Crushed basalt is considered a sustainable resource for carbon capture. It is a by-product of the aggregate industry and is abundant worldwide, making it a scalable option for carbon capture efforts. Additionally, basalt can be sourced locally, significantly reducing transportation-related emissions.
Looking ahead, Undo aims to distribute enough basalt to sequester one million tonnes of carbon dioxide from the atmosphere by the following year. This method is regarded as a scalable and expedient approach to tackle climate change effectively.
Q1. What is crushed basalt used for in agriculture?
Answer: Crushed basalt is used in agriculture to capture carbon dioxide and improve crop growth through enhanced rock weathering, enriching soil and enhancing yields.
Q2. How does basalt benefit crop production?
Answer: Basalt enhances crop yields and improves grazing land quality by enriching the soil with essential minerals, promoting better plant growth.
Q3. Why is the company 'Undo' providing basalt for free?
Answer: Undo provides basalt at no cost to farmers, funded by carbon credits purchased by large companies seeking to offset their carbon emissions.
Q4. Is basalt a sustainable resource for carbon capture?
Answer: Yes, basalt is abundant and a by-product of the aggregate industry, making it a scalable and sustainable option for carbon capture in agriculture.
