Karo Sambhav recycles e-waste and designs EPR programmes for global brands

It raised ₹56 crore in a Pre-Series A round led by Rainmatter by Zerodha

Karo Sambhav raised ₹56 crore in a Pre-Series A round.
The round was led by Rainmatter by Zerodha, the investment arm of Zerodha.
The company will use the funds to expand infrastructure for recovering critical minerals from e-waste.
It will initially focus on e-waste recycling and later expand to other waste streams.
Target materials include lithium, gold, silver, tin, indium, cobalt, nickel, copper, and platinum group metals.
Karo Sambhav was bootstrapped for nine years before this round.

India generates about 4.1 million metric tonnes of e-waste annually, making it the world's third-largest generator.
Global e-waste volumes are expected to reach 82 million tonnes by 2030.
India's waste recycling services market is valued at over $3.3 billion with a projected CAGR of about 9.8%.
Urban mining supports India's National Critical Minerals Mission to reduce import reliance.
A large portion of Indian e-waste flows through the informal sector, so formal recyclers compete for feedstock.

Karo Sambhav was founded in 2017.
It designs and implements EPR (Extended Producer Responsibility) programmes for e-waste, battery waste, plastic waste, and glass waste.
The company works with 30+ global tech and FMCG brands, including Apple, Dell, Cisco, Pepsico, and HP.
It operates two recycling plants.
Its collection network covers 50+ cities in India.
It has processed over 150,000 metric tonnes of e-waste to date.
The company recovers critical minerals such as lithium, gold, silver, tin, indium, cobalt, nickel, copper, and platinum group metals.
Technology for high-purity mineral extraction is capital-intensive and requires constant innovation.
