New Delhi, July 24 -- Microsoft is spending billions to buy 4.9 million metric tonnes of organic waste, including human waste, to support its green goals.

According to a report by Inc, in efforts to double down on its carbon removal goal, Microsoft signed a deal with Houston-based startup Vaulted Deep. The deal is aimed at helping the tech giant reduce its carbon footprint over 12 years.

As part of the deal, Microsoft will not just buy human waste. It will also purchase manure, treated sewage, and agricultural byproducts as part of the deal, for Vaulted Deep to use them to reduce carbon footprint.

To put Microsoft's deal with Vaulted Deep into context, it's necessary to understand the motive behind the tech giant's move.
