Biodigestão anaeróbia da vinhaça: aproveitamento energético do biogás e obtenção de créditos de carbono – estudo de caso

Abstract: ResumoA crescente produção de etanol no Brasil acarretou aumento na produção de vinhaça (principal subproduto da indústria sucroalcoleira), agravando o problema de sua destinação. A vinhaça é rica em nutrientes minerais e apresenta elevado teor de matéria orgânica, o que justifica sua intensa utilização na fertirrigação de áreas cultivadas com cana. Neste cenário, a biodigestão anaeróbia da vinhaça em reatores UASB (upflow anaerobic sludge blanket digestion) surge como uma alternativa de tratamento deste subpr… Show more

“…Production and use of that energy source, or its indirect advantages (Szimanski et al, 2010;Solomon et al, 2011), is a way to reduce costs due to the concentration of biodigested vinasse. This concentration could make transport viable and the application of K and other nutrients found in vinasse in areas where these nutrients were withdrawn during the sugarcane harvest.…”

“…Considering the production of ethanol in Brazil, in the crop year 2013/2014, at around 25.04 billion liters, vinasse production was at least 250 billion liters (Szymanski, Balbinot andNagel, 2010 andBelincanta, et al, 2016).…”

“…The beneficial effects of vinasse in agricultural crops are already well known, and studies on vinasse biodigestion have already been performed by several authors, among them Cabello et al (2009) and Szymanski et al (2010).…”
