Background: Management of solid waste is a set of regular and coherent acts on production control, storage and collection, handling, processing and disposal of solid waste. These activities should be in accordance with best conditions of public health, economy, and protection of industries, aesthetical and other aspects of environmental and public requirements. People cooperation in solid waste...
A one-dimensional multiphase numerical model is developed to simulate the vertical settlement involving liquid and gas flows in a deformable settling municipal solid waste MSW landfill. MSW is represented by a chemical composition, and a global stoichiometric reaction is used to estimate the maximum yield of gas generation. Following the general assumption accepted in the literature, the gas ge...
Waste-to-energy (WtE) facilities have been established worldwide as a sustainable method for the disposal of residual waste. In the present study the following competing WtE systems were compared: (1) municipal solid waste incinerators (MSWIs) with energy recovery; (2) co-incineration of waste in old lignite or coal-fired power plants; (3) substitute [refuse-derived fuel (RDF)] incinerators wit...
Background & Aims of the Study: Collection and transportation of municipal solid waste (MSW) for various reasons, especially economic and social are considered as one of the most important elements of the solid waste management system. More than sixty percent of the costs in solid waste management systems in different countries are due to the collection and transportation...
Tehran, the capital city of Iran and a metropolis with a population of 8.2 million and containing 2.4 million households, generated 2,626,519 tons of solid waste in 2005. The present study is aimed at evaluating the generation, characteristics and management of solid waste in Tehran. Municipal solid waste comprises more than 97% of Tehran's solid waste, while three other types of solid waste co...
Introduction: The amount and composition of municipal solid waste, as basic data, require to design, operation and optimization of waste management systems. The aim of this study was to investigate the qualitative and quantitative of municipal solid waste in tabriz city. Materials and Methods: This is a cross-sectional study. The samples were collected from all regions (10 regions) of Tabriz...
organic fraction of solid waste, which upon degradation produces foul smell and generates pathogens, if not properly managed. composting is not a method of waste disposal but it is a method of waste recycling and used for agricultural purposes. an integrated approach of composting methodology was tested for municipal solid waste management. solid waste first was composted and after 22 days, was...
if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...
Background and Objectives: The quantitative and qualitative data on urban solid waste is one of the essential steps in the scientific management of solid waste. The purpose of this study was to survey the qualitative and quantitative production of solid waste in Mashhad. Materials and Methods: In this descriptive study, in order to examine the quality of the samples, the separated materials we...
Modelling for environmental assessment of municipal solid waste landfills (part II: biodegradation).
The biodegradation module of a simulation program for municipal solid waste landfills (MODUELO) was developed. The biodegradation module carries out the balance of organic material starting with the results of the hydrologic simulation and the waste composition. It simulates the biologic reactions of hydrolysis of solids and the gasification of the dissolved biodegradable material. The results ...
