Producing carbon-negative, high-yield fertilizer for farmers in emerging economies
Our solution's stage of development:
ResearchOur solution:
From agricultural waste, we utilize a low-cost, mobile technology to produce carbon-negative fertilizer that improves local soil fertility.
Our pitch:
Our low-cost technology and unique chemical recipe allow us to provide thermochemical densification on-site. Imagine a reactor unit that can be latched onto the back of tractors and donkey carts, and can move from farm to farm for localized conversion into a product that has immediate local value, thereby eliminating this long-distance transport and creating a locally valuable biochar-based fertilizer called Safi Sarvi. Compared to traditional commercial fertilizers, Safi Sarvi retains nutrients and moisture more effectively, and reverses chronic soil acidification. Therefore, by paying the same price for fertilizer, farmers actually see their yield increase by up to 30%. Furthermore, because our product consists of an inert carbon-rich substrate that can stay unreacted in the soil for hundreds of years, applying one ton of our product to the soil sequesters up to 1.6 tons of CO2 from the air. Our reactors have been developed at Massachusetts Institute of Technology (MIT), and successfully tested both in laboratory and commercial settings. Our reactors rely on no external heat to power itself, and drastically reduce the emissions (both CO2 and other pollutants such as PAH, particulates, NOx, etc.) compared to status quo. So far we have installed >150 reactor units in 5 countries. Finally, by converting local agricultural waste through our solution, we enable income generation and localized access to high-yield fertilizer, thereby providing economic incentives for farmers and entrepreneurs to adapt our solution.
