In developing Asian countries, the municipal cooperations are unable to handle the increasing amount of municipal solid waste, which into the uncollected waste being spread on roads and in other public areas leading to tremendous pollution and destruction of land and negative impact on human health. Generation of municipal solid waste increases with the rapid urbanization and accelerated economic development with in the rapidly growing advanced technological societies. The nature of municipal solid waste is a term usually applied to a heterogeneous collection group of waste produced in urban areas, the nature of which varies from region to region. The common problem faced by all developing Asian countries, is the disposal of municipal solid waste and availability of land fill site area. Present study explains the correlation analysis of among different factors of municipal solid waste and the objective is to assess the future municipal solid waste stream in Asian developing countries. The other goal of this study was to calculate the future land area that would be required for landfill site disposal in Asian developing countries.

    • "The per capita waste generation varies for different studies. For example, Khajuria et al., (2010) claimed that the per capita waste generation was 0.65 kg day -1 in 2007 while in another study it was projected to be 0.60 in 2020 (Das et al., 2014). Here, the per capita waste generation was calculated as the average of Alamgir and Ahsan, 2007 and Enayetullah et al., (2005). "

    ABSTRACT: Every day we are producing some wastes from our daily leftover materials. Waste can be resources, if we can recycle and reused them. The waste generation is creasing with increase of income. Moreover, urban population is increasing around 4% per year. There is dearth of study regarding waste generation and recycling potentials of Bangladesh. Here, we reviewed the available studies and information to get insight into waste generation scenarios and proposed a possible ways for organic waste management. The waste generation was calculated based on population of the cities and per capita waste generation which was adopted for the 2014 using gross domestic product (GDP) growth rate and per capita gross national income (GNI). The waste generation from urban areas of our country is over 23290 and 27350 t per day-1 respectively for GDP and GNI based calculation. Half of the waste remain uncollected and causes environmental pollution. A new paradigm of simultaneous composting and pyrolysis can be a sustainable option for carbon and nutrient cycling. More than 75% of the wastes are estimated to be organic waste. Around 57% of the wastes is considered to be compostable while 26% is pyrolisable. The fraction of wastes (11%) can be used as fuel for pyrolysis. Around 54% C, 30% N, 68% P and 69% K can be recycled, if new approach is adopted.

    • "In recent years, a number of analyses were carried out to determine which factors influence waste generation. The study were conducted in the Netherlands (Hekkert et al., 2000), Denmark (Christiansen and Fischer, 1999), Austria (Salhofer and Graggaber, 1999), Tehran (Jalili Ghazizade and Noori, 2008), Bangladesh (Afroz et al., 2011) and many other countries (Anupam et al., 2010; Bach et al., 2004). Researchers have produced different models to attempt to explain the variation in waste generation. "

    ABSTRACT: In this study the effect of gender and age structure on municipal waste generation was investigated. The data from 10-year period, from 2001 to 2010year, were taken into consideration. The following parameters of gender and age structure were analyzed: men and woman quantity, female to male ratio, number of working, pre-working and post-working age men/women, number of unemployed men/women. The results have showed a strong correlation of annual per capita waste generation rate with number of unemployed women (r=0.70) and female to male ratio (r=0.81). This indicates that waste generation rate is more depended on ratio of men and women that on quantitative size of each group. Using the regression analysis a model describing the dependence between female to male ratio, number of unemployed woman and waste quantity was determined. The model explains 70% of waste quantity variation. Obtained results can be used both to improve waste management and to a fuller understanding of gender behavior. Copyright © 2015 Elsevier Ltd.

    • "The quantity of municipal solid waste (MSW) in developing countries has been consistently rising over the years and its composition is similar but varies from country to country depending on the average standard of living, climate and cultural, industrial, infrastructural and legal factors (Khajuria et al., 2010). MSW disposal in most developing countries around the world poses major environmental problems. "

    ABSTRACT: The city of Astana, capital of Kazakhstan with population of 804,474 generates approximately 1.39 kg/inh./day of municipal solid waste while collection rate is higher than 72% (MSW). An MBT plant of planned capacity of 600-800 tn/day and a new landfill cell of about 2 million tones are in place. Preliminary studies showed that the MSW composition is as follows: food and garden waste 29.5%, plastics 18.5%, paper 13%, glass 14.5%, textiles 9.5%, metals 0.9% and others 14.1%. About 23-34 tons of recyclables (paper, metal, glass, PET bottles, HDPE film, HDPE plastic, etc.) is separated in the existing MBT daily. In 2014 it is planned to implement separate waste collection in places of waste accumulation and a waste separation at source system. The purpose of the study is to assess the current situation of municipal solid waste in Astana and implement a Decision Support Software tool developed by the research team in order to analyse data, compare alternative waste management scenarios and propose a holistic approach in solid waste management planning. The latest available data on waste generation, composition and existing infrastructure were used in order to identify the baseline situation. This is the first research of this type conducted in Kazakhstan.
