GREEN LABELED HYDROGEN FROM THE ORGANIC WASTE OF SÃO PAULO'S MARKETS AND STREET FAIRS

Abstract

Street markets of the city of São Paulo produce around 360 tons/day of vegetable solid waste (VSW) which is practically all food waste. The VSW collected by the city is currently sent to sanitary landfills.This study evaluates the potential for generating "green hydrogen" from this VSW. The treatment of VSW from street markets and supply centers can produce biogas through anaerobic digestion. This biogas can be purified into biomethane and then reformed into hydrogen. Hydrogen production from methane reforming is a well established process. Using biomethane will produce "Green Labeled H2". Based on the projected population growth of the city, the estimated VSW production will reach 410 tons/day by 2043. In this scenario, all of the generated VSW is collected and used for this process. Plants around the city will be able to provide adequate treatment for this waste and produce 1,585 t/year of "Green Labeled H2" by 2043
