Waste is a byproduct of human life. Nowadays, municipal solid waste is being produced in excessive amounts and in this way, both developing and developed countries are facing challenges regarding generation of waste. Economic development, urbanization and improved living standards in cities have contributed to increase in the amount and complexity of solid waste produced. The present stud...

Decentralized eco-sanitation system is a promising and sustainable mode comparing to the century-old centralized conventional sanitation system. The decentralized concept relies on an environmentally and economically sound management of water, nutrient and energy fluxes. Source-separation systems for urban waste management collect different solid waste and wastewater streams separately to facil...

A test substance with characteristics and properties similar to those of cellulose· based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce. Microcrystalline cellulose was found to be a good calibrant for this purpose. The enthalpy of combustion of microcrystal...

Depending on their nature and severity, disasters can create large volumes of debris and waste. The waste can overwhelm existing solid waste management facilities and impact on other emergency response and recovery activities. If poorly managed, the waste can have significant environmental and public health impacts and can affect the overall recovery process. This paper presents a system overvi...

As a key utility service that more than 2 billion people are currently lacking, solid waste management (SWM) is a crosscutting issue that can be directly linked to 12 out of the 17 UN Sustainable Development Goals (SDGs). Distinguishing between physical components and governance aspects of SWM, this research focuses on governance issues concerning basic solid waste collection services and contr...

In this study, Halomonas boliviensis was cultivated on bakery waste hydrolysate and seawater in batch and fed-batch cultures for polyhydroxybutyrate (PHB) production. Results demonstrated that bakery waste hydrolysate and seawater could be efficiently utilized by Halomonas boliviensis while PHB contents between 10 and 30% (w/w) were obtained. Furthermore, three methods for bakery waste hydrolys...

The dominant policy decision emphasis on urbanisation problem in developing countries is itsrate of growth, ignoring the level of provision of resources, including the infrastructure, to match this growth. It isagainst this background that the paper undertook a broad analysis of the state of infrastructure in developing countriesusing such indices as access and quality of water supply, sanitati...

Environmental hazards as a consequence of mass consumption and waste disposal remain largely unconsidered in affluent societies. Resources embodied in waste are not recognized. In Latin America, Asia and Africa, in particular, an extensive informal sector is involved in the collecting and separating of recyclable materials. This widespread activity provides an insight into the resourcefulness o...
