Alt Carbon Aims to Tackle Climate Change with Innovative Approach

Siblings Shrey and Sparsh Agarwal founded Alt Carbon after trying to revive their family’s struggling tea estate in Darjeeling, India. Initially considering carbon markets, they found them lacking in quality. The brothers discovered a more viable solution: enhanced rock weathering.

What is Enhanced Rock Weathering?

This process involves using waste basalt rock dust from mines and quarries in Eastern India to lock away carbon dioxide for thousands of years on farm fields.

  • Key Benefits:
    • Not just planting trees; it changes the chemistry of the soil.
    • The basalt dust reacts with rainwater to form stable bicarbonate ions.
    • These ions are stored in the soil and eventually flow into oceans, where they settle as calcium carbonate for over 10,000 years.

Expansion Plans

Alt Carbon aims to expand its work beyond tea farms to include rice and bamboo crops. The startup hopes to remove 5 million tons of carbon by 2030 across 500,000 hectares of land.

Funding and Growth

To achieve this goal, Alt Carbon has secured $12 million in funding from investors, including the Physical Intelligence company, which is leading the investment round.

  • Use of Funds:
    • Scaling up operations
    • Building new labs
    • Deploying sensors
    • Increasing staff size
    • Hiring PhDs

Frontier, a previous investor, had purchased $500k worth of credits before Stripe led an advanced market commitment last year, which included major companies like Alphabet, Meta, Shopify, and McKinsey.

Alt Carbon is positioned to make a significant impact on climate change through innovative practices and strategic partnerships.
