As the largest solid waste (SW) generator in the world, China is facing serious pollution issues induced by increasing quantities of SW. The sustainability assessment of SW management is very important for designing relevant policy for further improving the overall efficiency of solid waste management (SWM). By focusing on industrial solid waste (ISW) and municipal solid waste (MSW), the paper ...

Ma’an city faces serious administrative challenges in managing their municipal solid waste (MSW) due to the lack of adequate information of the composition and quantities of generated solid waste. The overall objective of this research is to gain more reliable information about quantities and composition of MSW stream in Ma’an city. In this work, field survey along with a separation study at wa...

Ethanol production strategy was studied using multiple strain microbes from microwave irradiation (MI) pretreated sago waste. Sago waste (SW) was MI-pretreated for reducing sugars production using 2 heating media (water and sulfuric acid) under pretreatment conditions including MI power, pretreatment duration, and solid loading. When water was used, the pretreatment parameters were optimized us...

background and purpose: an appropriate solid waste (sw) disposal has been a major problem in municipal environment. the use of landfills is the most economical and environmentally acceptable method for the disposal of sws all over the world. however, landfill leachate can cause environmental issues such as soil and ground water pollution. so, finding suitable land fill site is one of the most s...

The purpose of this paper is to support the development of so-called good practice guidelines for the estimation of methane (CH4) emissions from solid waste (SW) disposal for national greenhouse gas inventories. The paper reviews and discusses the emission estimation methods given in the IPCC 1996 Revised Guidelines (IPCC Guidelines), and uncertainty and quality management issues related to the...

Nigeria is the most populous country in Africa. Located on the western part of Africa, it has a population of over 140million people. The country has had an annual increase in population growth rate of 3.2% from 1991. The rate of urban growth has also been estimated at 5.5% per annum. Nigeria is made up of 36 states, excluding the Federal Capital Territory (FCT) Abuja, with Lagos and Kano State...

a trend of significant increase in municipal solid waste generation has been recorded worldwide. this has been found due to over population growth rate, industrialization, urbanization and economic growth. consumerism speed has been found very high covering around more then 50% of total population since last decade due to higher economic growth, which has ultimately resulted in increased solid ...

An adaptation is presented of method 8261--from the Office of Solid Waste and Emergency Response Test Methods for Evaluating Solid Waste Physical/Chemical Methods (SW-846)-to analyze milk for an expanded list of volatile organic compounds is presented. The milk matrix exhibits a strong affinity for organic compounds and the surrogate based matrix normalization described in method 8261 provided ...

background and purpose: due to the lack of accurate statistics on the amount of waste generated in the energy production sector in zahedan, before any planning, one should identify all waste producing centers associated with the energy sector and also the quantity and quality of their waste in zahedan. materials and methods: this research is a cross-sectional descriptive study. it examined the ...
