This paper presents a multi-objective optimization model for the design of a waste management system consisting of customers, transfer stations, landfills and collection vehicles. The developed model aims to simultaneously minimize the total costs, greenhouse gas emissions and the rates of energy consumption. To tackle the multiple objectives in the problem, we utilize an interactive fuzzy prog...

This study was carried out to reveal the plastic wastes separation practice and disposal mechanism as well as awareness of the negative impact of plastic wastes on the environment, in Makurdi area of Benue State, Nigeria. Questionnaires were administered to 468 individual respondents in 6 sub-locations of the city. Inquisition was also made from 10 hospitals, 6 market centers and the waste mana...

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...

Waste management and energy systems are often interlinked, either directly by waste-to-energy technologies, or indirectly as processes for recovery of resources—such as materials, oils, manure, or sludge—use energy in their processes or substitute conventional production of the commodities for which the recycling processes provide raw materials. A special issue in Energies on the topic of “Ener...

Waste management is a distinct practice aimed at reducing its effects on health and the environment and increasing energy and material recovery. The urban waste management industry has been slow to adopt new technologies, such as sanitary landfills and incineration, which enable better treatment results. The aim of a thorough ecological-economic evaluation of different treatment technologies is...

Clean Air Act Amendments of 1990, however, mitigate the risks to public health and make incineration an alternative worth exploring. Incineration can reduce solid waste to 85 percent to 90 percent of the incoming volume, or 65 percent to 80 percent of the incoming weight. With some modification, a waste incinerator can be designed to recover energy in the form of steam, hot water or electricity...

Waste to energy is an answer to the growing demand for fossil fuels. Pyrolysis plays an important role in waste to energy technologies. The product obtained from pyrolysis depends on various physical parameters that influence the reaction mechanism. Pyrolysis reactions can be classified onto flash, fast and slow pyrolysis depending on temperature and heating rate. This paper discusses the effec...

This paper examines the limits of microprocessor energy reduction available via certain classes of architecture-level optimization. It focuses on three sources of waste that consume energy. The first is the execution of instructions that are unnecessary for correct program execution. The second source of wasted power is speculation waste – waste due to speculative execution of instructions that...

The USA has significant experience in the field of municipal solid waste management. The hierarchy of methodologies for dealing with municipal solid wastes consists of recycling and composting, combustion with energy recovery (commonly called waste-to-energy) and landfilling. This paper focuses on waste-to-energy and especially its current status and benefits, with regard to GHG, dioxin and mer...
