Energy recovery from municipal solid waste of intermunicipal public consortia identified in São Paulo State

Abstract

The main reasons, which this research is based on, are evidenced by the need of technical, political, economic and socioenvironmental coordination for the municipal solid waste management in Brazil and in the State of São Paulo. Most of the counties do not have adequate size to promote the management of MSW, so it’s necessary to perform a consortia to do it. Therefore, it was necessary to characterize the current State of Sao Paulo consortial arrangements considering the environment (including sanitation, waste, water resources, among others). The scale of waste generation and the total population involved in these consortia were also considered. The energy potential of municipal solid waste was evaluated considering two possible technologies: The burning of landfill biogas in engines and the incineration in plants with Rankine cycle. It was identified that the sum of consortia energy potential was 1,454,336 MWh y–1 (landfill biogas), and 2,715,925 MWh y–1 (incineration). It is intended that such results provide significant information and encourage interaction between the different agents involved in the intermunicipal arrangements. It is expected that the characterisation and calculation of energy potential will stimulate future studies about new consortia approaches that consider energy recovery in their projects.

Elevated biogas production from the anaerobic co-digestion of farmhouse waste: Insight into the process performance and kinetics

“…To date, it is crucial to sustainably improve the rural areas life by materials recovery and reduced energy consumption (Lamidi et al, 2019). The use of highly lignocellulosic waste streams may be a constraint for the applicability of AD technology owing to their recalcitrance (Achinas and Euverink, 2016; Dalmo et al, 2019; Martínez et al, 2019; Smuga-Kogut et al, 2019).…”

Waste-to-energy technology for the brazilian context

“…This method can be defined as a thermochemical process that, through complete oxidation, aims to decrease the volume and mass of the waste, prolonging the useful life of landfills (Santos et al, 2019;Dalmo et al, 2019a;Dalmo et al, 2019b). According to Silva et al (2019), in this process, oxygen reacts with combustible elements present in the waste (at temperatures above 800 °C), such as carbon, oxygen and sulfur, converting chemical energy into heat.…”

“…Colvero et al (2020) add that in addition to the production of heat, it is possible to produce electricity through the heating energy of materials. In this process, the generation of energy occurs after the generation of steam in boilers, which is sent to the turbines, resulting in electrical energy (Dalmo et al, 2019a;Dalmo et al, 2019b).…”

Effect of Temperature and Organic Load on the Performance of Anaerobic Bioreactors Treating Grasses

“…To date, it is essential to sustainably ameliorate rural areas' life by materials recovery and diminished energy consumption [31,32]. The use of highly lignocellulosic waste streams may be a restriction for the applicability of AD technology because of their recalcitrance [33][34][35].…”
