- Darjeeling-based company, Alt Carbon, is turning mining dust into a climate-friendly solution.
- It utilising a geo-chemical process known as enhanced rock weathering to tackle atmospheric carbon dioxide (CO2).
- Being an organic fertiliser, the basaltic dust enriches the soil as well as accelerates carbon sequestration.
- It takes about a 3-4 tonnes of basalt dust to sequester, or trap, a tonne of atmospheric carbon over two to four years.
- Carbon sequestration is the process of capturing and storing atmospheric CO2.
- The oceans are the major carbon sinks and capture about 30% of the CO2 from human activities.
