Solid waste

The study aimed to evaluate the current campus waste management practices and provide suitable suggestions. As a result, feasible and suitable alternatives that identify specific and locally relevant prospects for waste reduction, reuse, and recycling can emerge, constituting a significant stride towards environmentally sustainable and health-conscious educational institutions.

The aim of this study is to enhance biogas production from the organic fraction of municipal solid waste (OFMSW) and garden waste (GW) via pretreatment and codigestion. In order to achieve the aims of the study, two objectives have been developed and are outlined below: To investigate an optimum co-digestion mixture of OFMSW with untreated and pretreated GW; to investigate the effectiveness of different pretreatments on the potential for biogas production from GW and to identify the relationship between certain changes in GW characteristics and enhanced yield.

Landfill gas from a source of green energy, clean, renewable and can be used to create electricity, or used in the energy industry. This paper reviews the potential energy recovery landfill gas from municipal solid waste, to reducing methane emissions in particular, and reduced greenhouse gas emissions in general. In addition, this paper provides an assessment using the model of methane generated from landfill municipal solid waste and generate energy potential of gas recovered. In particular, this paper uses a life cycle assessment methods ......

MBR (Membrane Brio-Reactor) can be broadly defined as systems integrating biological degradation of waste products with membrane filtration. Set up of MBR plant is mainly utilizing a bioreactor and membrane filtration as one unit process for wastewater treatment thereby replacing, and in some cases supplementing, the solids separation function of secondary clarification and effluent filtration, resulting the possibility to eliminate the secondary clarification and operate at higher MLSS concentration....

The addition of clay in the form of bauxite refining residue (red mud) prior to composting has been suggested as a way to control heavy metal mobility in compost. Leachability and plant availability of metals in a mixture of grass clippings and sawdust spiked with metal solution was markedly reduced during the composting process.

Toxic heavy metals, i.e. copper (II), lead (II) and cadmium (II), can be removed from water by metallurgical solid wastes, i.e. bauxite waste red muds and coal fly ashes acting as sorbents. These heavy-metal-loaded solid wastes may then be solidified by adding cement to a durable concrete mass assuring their safe disposal. Thus, toxic metals in water have been removed by sorption on to inexpensive solid waste materials as a preliminary operation of ultimate fixation. Metal uptake (sorption) and release (desorption) have been investigated by thermostatic batch experiments.

Australia, Australia (First received October 1995; accepted in revisedform September 1996) Abstract--Sewage sludge usually contains significant heavy metals that may limit its land application. Heavy metals in municipal solid waste have been shown to be less mobile by amendment with bauxite refining residue (red mud) prior to the composting process.

A pilot study was conducted to assess the feasibility of composting of source separated organic matter of municipal solid waste (MSW) generated in low, middle and high income areas of Karachi city with a population over 14 million. Results of MSW analysis indicate the presence of high percentage of biodegradable organic matter (71-74%), acceptable moisture content (40-50%) and C/N ratio (38-40:1). On windrow composting, not only the volume of waste was reduced but also produced a crumbly earthy smelling soil-like, compost material.
