Solid waste generation and characterization are some of the most important parameters which affect environmental sustainability. Municipal solid waste (MSW) characterization depends on social structure and income levels. This study aims to determine the variations in waste components within MSW mass by income levels and seasonal conditions following the analysis conducted on the characterizatio...

background: successful waste management programs are linked to internal factors, sw (strength and weakness points), and external factors, ot (opportunities and threats), and at the macro level are grounds for sustainable development. studies may be related to david’s study which presented a method to quantify strength, weakness, opportunity, threats (swot) analysis. methods: in this study, desi...

compost is one of the strategies of house hold solid wastes management that is used to decrease the volume and weight of wastes, odor and leach ate dispersion, resource recycles and decreasing disposal expenses. in order to observe environmental regulations in the frame of adaptation development projects with environmental concerns, assessment of environmental impact of composting plants has be...

A pilot-scale study was undertaken to evaluate alternatives to the solid waste management of a Central American municipal market located in Estelí, Nicaragua. The municipal solid waste from the local market is the second largest contributor to the municipal solid waste (MSW) stream. Waste from the market without any previous sorting or treatment is open dumped. The options evaluated in this stu...

background: production of solid waste is the result of the human’s different activities that today has changed a lot in comparison to the past due to the changing life styles and pervasive expansion. in isfahan province lots of wastes are produced daily. due to the importance of the waste and its recycling, the purpose is determining the production scopes of different wastes in order to find a ...

conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...

fly ash is one of the most plentiful and versatile of the industrial by-products. at present, nearly 150 million tonnes of fly ash is being generated annually in india posing dual problem of environmental pollution and difficulty in disposal. this calls for establishing strategies to use the same effectively and efficiently. however, it is only in geotechnical engineering applications such as t...
