The energy demand and waste generation have increased significantly in the developing world in the last few decades with rapid urbanization and population growth. The adequate treatment of the waste or sustainable waste management is essential not only from a sanitation point of view but also due to its economic and environmental values including its potential contribution to energy generation in the developing countries. Many of the developed nations have adopted the approach and strategies of the integrated waste management system (Figure 1) to maximize the waste-based revenues in the form of energy, fuels, heat, recyclables, value-added products, and chemicals along with more jobs and business opportunities. As a result, waste is no longer seen as refuse or discarded material, but an asset or resource to reduce not only the landfill volumes but also the dependency on fossil fuels by generating clean fuels.
Municipal solid waste (MSW) is a global environmental problem. Its quantity is increasing with corresponding increase in population. Safe disposal of MSW is a big challenge for municipal authorities. One way of disposal of MSW is in landfill sits and the other is to make its beneficial use as fuel for power generation. MSW is easily available in abundance and is a cheap source of energy for power generation. Solid waste incinerator can remove up to 99.9999 percent of all toxins from their emissions and as such are no more harmful to the environment; in comparison MSW landfills emit methane-gas, and leachates that are hazardous for environment and ground water. This research study has examined the possibility of waste to energy project for capital city of Pakistan, and has carried out its technical and financial feasibility analysis. This technically feasible and cost effective project will not only solve the MSW disposal problem, but would improve the environment of the city along with providing electricity and saving precious foreign exchange used for import of fuel.

In recent years, the management of waste treatment in Indonesia has become a critical issue among the stakeholders both in the government and the private sector. One way to significantly reduce waste in each region is to use incinerator technology. This technology has developed in Japan, South Korea and Europe. The burning of waste can produce electricity or the so-called waste to energy. However, to build a power plantthat utilizes waste requires policy support from the Central and Regional Governments. This study seeks to identify the types of support that Central and Regional Governments can provide to develop waste to energy.

This study analyses the municipal solid waste management system of 172 countries from all over the globe with a population of 3.37 billion. This study indicates that we generate around 1.47 billion tonnes (436 kg/cap/year) of municipal solid waste each year and waste generation is increasing over time. This study also found that there is a positive correlation (r ¼ 0.539, p < 0.05) between per capita income gross domestic product(GDP/capita/year) and per capita waste generation (kg/capita/year) and a similar correlation is also observed (r ¼ 0.653, p < 0.05) between per capita income (GDP/year) and per capita resource recovery (kg/year). The findings of this study show that globally, about 84% of the waste is collected and only 15% of the waste is recycled and most of the global waste was still managed by landfills. This study tries to measure the environmental benefits of global waste management systems by applying a tool called the Zero Waste Index (ZWI). The ZWI measures the waste management performance by accounting for the potential amount of virgin material that can be offset by recovering resources from waste. In addition, the ZWI tool also considers the energy, greenhouse gas (GHG) and water savings by offsetting virgin materials and recovering energy from waste. The ZWI of the world in this study is measured to be 0.12, which means that the current waste management system potentially offsets only 12% of the total virgin material substitution potential from waste. Annually, an average person saves around 219 kWh of energy, emits about 48 kg of GHG and saves around 38 l of water. The global municipal solid waste management systems potentially contributed around $201.5 billion or around $60 per person of economic benefits annually.
