“…As such, substantial improvements in the efficiency of energy and resource use as well as reductions in waste and emission generation are needed [10]. WER management is one of the ways to achieve sustainability [7,8]. Significant amounts of energy and resources are consumed in manufacturing and significant amounts of waste are produced [6].…”

“…Additionally, pressures from stakeholders and also material costs and scarcity push manufacturers to move towards sustainable manufacturing practices, such as reducing material and energy consumption as well as waste generation [6]. As such, research on waste, energy, and resource (WER) management has received special attention [7,8].…”

The management of waste, energy, and resources has received special attention from academics and practitioners due to the growing evidence for its effects on the environment. The aim of this study is to investigate the environmental drivers of waste, energy, and resource management and, in turn, its effect on the sustainable performance of manufacturing firms. The data were collected from a survey of 173 large manufacturing firms in Malaysia and analysed using partial least squares. The results indicate that although environmental regulatory pressure, customer pressure, environmental uncertainty, and expected business benefits have positive effects on the extent of waste, energy, and resource management, social responsibility has no effect. Furthermore, waste, energy, and resource management has a positive effect on the sustainable performance of large manufacturing firms. The findings of this study extend the knowledge of the drivers and outcomes of waste, energy, and resource management. The results can help policymakers to adjust policies and strategies in a way to inspire managers to implement waste, energy, and resource management.

Purpose This study aimed to examine the possibilities of the treatment of the by-products generated in the anaerobic digestion (AD) of the organic fraction of municipal solid waste (OFMSW): oxygen stabilization (composting) of the solid digestate and pretreatment with air stripping of the effluents (liquid digestate and leachate from maturation field and reactors from composting). Methods Oxygen stabilization (OS) was performed in full-scale in a mechanical-biological treatment (MBT) plant using three different methods, using an open field or enclosed box reactor with aeration. The ammonia stripping was performed in a pilot-scale installation using effluents from AD (liquid digestate) and OS (leachate from maturation field and reactors). Results The lowest self-heating possibility after the OS was recorded at 28.5 °C, which proves that the most stabilized was the sample after processing with structuring material addition. Due to air stripping, the highest efficiency of ammonium ions removal was noted at the level of 50.6%, with an initial pH value of 10.5, after 12 h. Among the examined factors pH value was found to be significant [the determination coefficient (R 2) of 0.93]. Conclusions The oxygen stabilization of the digestate requires the structuring material addition before being placed in the reactor with aeration. The inert fraction from the ballistic separation of the OFMSW can be an interesting solution, as required structuring material. Air stripping as the effluents pre-treatment step can meet the MBT plants expectations.

“…Estes modelos matemáticos podem ser usados, por exemplo, para estimar a receita operacional relativa aos ganhos dos produtos resultantes do sistema de gestão de RS, tais como materiais recicláveis, fertilizantes e energia elétrica (CHANG; PIRES, 2015). Em relação aos resultados ambientais, é possível levantar diferentes pesquisas que utilizam modelos matemáticos para projetar impactos da gestão de RS na emissão de Gases de Efeito Estufa (GEE) e na ocupação de área para disposição final de resíduos (CHO; MOON; KIM, 2012;CREMIATO et al, 2018;GOLLAPALLI;KOTA, 2018;KARANJEKAR et al, 2015;KUMAR;SHARMA, 2014;YOUNES et al, 2016).A estimativa das emissões de gases metano (CH4) e carbônico (CO2) é uma etapa importante no estudo e planejamento do setor. Segundo Turner, Kemp e Williams (2011), as emissões de CH4 e CO2 são responsáveis por 90% do total de GEE gerados pelos resíduos.…”

A busca por um sistema de gestão de Resíduos Sólidos Urbanos (RSU) sustentável é um desafio para gestores municipais. Para isso, é necessário inicialmente entender o atual sistema de gestão e seus futuros resultados. Este trabalho teve o objetivo de realizar o prognóstico do atual sistema de gestão de RSU do município de Juazeiro do Norte no Ceará. O estudo é quantitativo e utilizou métodos quantitativos de modelagem para estimar, em um período de 20 anos (2016 a 2035), impactos ambientais de ocupação de área por aterro e de emissão de gás metano (CH4) e de gás carbônico (CO2). Os resultados apontam que, caso nada seja feito, os RSU coletados e enterrados no aterro do município, entre 2016 e 2035, ocuparão uma área equivalente a 20 campos de futebol (147.140 m2) e emitirão aproximadamente 153.300 e 420.600 toneladas de CH4 e CO2, respectivamente, que se estenderão por 40 anos. Os resultados dessa pesquisa destacam um cenário futuro preocupante que pode e deve ser mitigado através do planejamento e implementação de alternativas de mudanças do atual sistema de gestão de RSU da região.
