Surface soils from Guiyu, China (an intense e-waste processing center) were analyzed for persistent organic pollutants (POPs) and variations in composition of the resident bacterial communities. Denaturing Gradient Gel Electrophoresis analysis of bacterial 16S rRNA gene showed that e-waste pollution altered the bacterial community structure by promoting changes in species composition and specie...

This paper utilized system dynamics modeling as a new analytical approach to predict both the municipal waste generated and the associated disposal costs in developing areas. This approach facilitates the decomposition of general waste into its main components to enable municipalities to manage recyclables and find out the feasibility of performing recycling better rather than disposal by perfo...

Waste water treatment is a large, complex and nonlinear system due to being influenced by big speed, pollution as well as the uncertainty related to the composition of the input waste stream. In reality, these systems are always required to operate continuously and stably so that the natural environment is able to absorb the treated waste water safely. Therefore, the size as well as operation q...

Urbanization and rapid growth of population in India has led to drastic increase in municipal solid waste. Unscientific disposal of municipal solid waste is one of the main reasons attributed for environmental degradation. The present work concentrates on municipal solid waste management in Tiruchirappalli City which comprises of four zones namely Srirangam, Goldenrock, Araiyamangalam and Abish...

Home composting (HC) is recognized by both local and national Governments for its contribution to reducing household waste disposal in landfill. However, the quantitative impact of HC on the diversion of household waste from landfill is uncertain. An overview of key results is presented from a 3-year research programme on HC in the West London area of Runnymede Borough Council (RBC), Surrey, UK...

The classical method of melting lead by fire-assay (Pb-FA) is the most frequently used analytical technique in gold prospection. The crucible solid waste which is generated in this process is usually characterized by chemical and mineralogical composition, granulometric size distribution, and classified according to Brazilian Environmental Regulations. This study demonstrates how acid leaching ...

This paper presents an examination of MSW generation and composition in China, providing an overview of the current state of MSW management, an analysis of existing problems in MSW collection, separation, recycling and disposal, and some suggestions for improving MSW systems in the future. In China, along with urbanization, population growth and industrialization, the quantity of municipal soli...

ion based on detailed computational thermal repository performance calculations has resulted in implementation of the STC estimation algorithm and a supporting reference dataset. This method is capable of rapid estimation of temperature increase near emplacement tunnels as a function of waste composition, limiting radius, rlim, waste package spacing, S, near field thermal conductivity, Kth, and...

The analysis of solid waste or incinerated residue for information regarding the chemical constituents involved the development and adoption of analytical methods. Methods were developed for the determination of nitro­ gen, carbon, hydrogen, protein, chemically decomposable organic and calorific values. The chemical composition of two types of residue and unburned solid waste was de­ termined u...
