The Swedish ordinance banning the landfilling of organic material after 2005 has led to rapid developments towards waste incineration, while biological alternatives have been less studied. In this study, biological alternatives for enhanced methane production from residual municipal waste (the remaining waste fraction after source separation) are investigated. The strategies investigated were recirculation of leachate, recirculation of leachate with aeration, flooding of the solid bed, and enzyme addition after initial leaching in an anaerobic, batch, two-stage digestion process with recirculation of digested leachate. The degree of solubilisation of organic compounds achieved was higher for initial digestion in a two-stage anaerobic digestion system followed by the addition of cellulolytic enzymes than in the other strategies investigated. The overall net solubilisation achieved was 0.48 g COD/g VSadded corresponding to an increase of 34%. In addition, the digestion time was considerably reduced using this strategy. For the other strategies investigated the solubilisation yields obtained were similar, 0.31 g COD/g VSadded.

This study aimed to map and estimate the potential of electricity generation from biogas produced through the anaerobic digestion process of vinasse in the state of Minas Gerais, Brazil, focusing on the energy use of an electric powered otto cyclemotor generator set. The potential for electric power generation was estimated from the amount of sugarcane produced in the 2018/2019 harvest in each municipality of the State. Then, the map was made with the spatialization of the information, in order to denote the municipal potentialities of the regions with the highest available energy indices. Energy availability was in the order of 746.43 GWh for each sugarcane crop, being more concentrated in the Triangulo Mineiro Region. Therefore, the use of this biomass waste into the anaerobic digestion process to produce electricity from biogas represents an environmental solution, an economical alternative and a social benefit.
