Proposta de dimensionamento de um biodigestor para produção do biogás no Mercado Grossista de Zimpeto

Abstract

The Zimpeto Wholesale Market has recorded significant annual growth, driven by the increase in the number of sellers and trade volume. This growth resulted in a greater production of solid waste, especially organic, which highlights the need for sustainable techniques for its management. The main objective of this study is to implement a biodigester sized as a strategic solution for the treatment of organic waste produced on the market. The study addresses the description and classification of solid waste generated in the Zimpeto Wholesale Market, characterizing its physical composition and estimating the amount of organic waste. The results indicate that approximately 77.42% of the 926 daily tons of waste are of organic origin, including cabbage leaves, carrots, lettuce, peppers, oranges, lemons, tangerines, cassava pieces and coconut shells. The other types of waste, such as garlic and onion peels, pieces of plastic, paper, sand and grass, correspond to 7.64%. Paper and cardboard waste represents 6.14%, plastics 2.99%, glass 2.93%, fine 2.84% and metals 0.04%. Based on the analysis of the data, the Canadian biodigester was selected, known for its ability to treat large amounts of waste, in addition to its easy installation and modern technology. The dimensionaling of the biodigester was then carried out to enable the production of biogas on the market.
