Samuel Rigu

Samuel Rigu is the co-founder and CEO of Safi Organics, a for-profit company in Kenya that produces and sells a carbon negative, organic fertilizer (Safi Sarvi) that helps rural farmers increase their farm yields by up to 30 percent and income by up to 50 percent. Their fertilizer, made locally from farm waste, shows a higher retention of water and nutrients over time versus traditional fertilizers, and also is slightly alkaline, preventing soil acidification. The product has additional environmental benefits: by selling and applying each ton of Safi Organics fertilizer, 1.1 tons of CO2 equivalent are sequestered from the atmosphere.
