Waste refineries focusing on multiple outputs of material resources, energy carriers, and nutrients may potentially provide more sustainable utilization of waste resources than traditional waste technologies. This consequential life cycle assessment (LCA) evaluated the environmental performance of a Danish waste refinery solution against state-of-the-art waste technology alternatives (incinerat...

Energy recovery from municipal solid waste plays a key role in sustainable waste management and energy security. However, there are numerous technologies that vary in suitability for different economic and social climates. This study sets out to develop and apply a multi-criteria decision making methodology that can be used to evaluate the trade-offs between the benefits, opportunities, costs a...

Decrease of fossil fuel dependence and resource saving has become increasingly important in recent years. From this perspective, higher recycling rates for valuable materials (e.g. metals) as well as energy recovery from waste streams could play a significant role substituting for virgin material production and saving fossil resources. This is especially important with respect to residual waste...

the province of bushehr is located in southern area of iran and north of persian gulf. solid waste management in bushehr’s villages was the aim of this research. for the sake of this study, 21 villages scattered all over the province were selected. field studies showed that about 646 grams of residential solid waste per capita is generated in selected villages every day. there are 322 shops i...

In this paper comprehensive studies have been carried out for the design optimization of a waste heat recovery system for effectively utilizing the domestic air conditioner heat energy for Keywords—Air-conditioning system, Energy conversion system, Hot water production from waste heat, Waste heat recovery system.

In spite of the past few decades, gasification of waste is being used in the developed countries. Reducing the space for landfill sites, producing fuel from waste, as well as avoiding negative impacts of landfilling, are of advantages of gasification. The research was aimed at feasibility study of application of Tehran municipal solid waste (MSW) gasification in addition to understanding the wa...

Annually more than 80% of the overall budget of the uran solid waste management system in Iran is allotted to collection and transportation of the solid wastes. The main objective of the current study is to evaluate the external costs associated with solid waste collection, transfer, and transportation in Tehran for the period of 2018 to 2032 based on the current situation. Waste guidance syste...

With ever increasing concern on oil prices and energy conservation, there is a fast growing interest in hybrid vehicles globally. Currently, all hybrid vehicles, including micro, mild and full hybrids, adopt internal combustion engines which are inefficient in general. The corresponding waste heat of exhaust gas constitutes up to 40% of the fuel consumption. So, it is a pressing need for resear...

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
