A Study between the Conventional Waste Management and Latest Waste Management Techniques in Developed & Developing Countries, its Scope and Challenges in the Developing Countries

The planet is at the mid of a threat due to the waste generated by human beings all around the world. The production of an increasing quantity and complexity of wastes pose a serious question to the future of the planet. The estimated quantity of only Municipal Solid Waste (MSW) generated worldwide is around 2 billion metric tons. In many cases, municipal wastes are not well managed in developing countries, as cities and municipalities cannot cope with the accelerated pace of waste production. Waste collection rates are often lower than 70 per cent in low-income countries. More than 50 per cent of the collected waste is often disposed of through uncontrolled landfilling and about 15 percent is processed through unsafe and informal recycling. Electronic waste (e-waste) is also one of the fastest-growing pollution problems worldwide given the presence of a variety of toxic substances which can contaminate the environment and threaten human health, if disposal protocols are not well managed. The key to success in terms of waste management is to develop eco-design devices, properly collect waste, recover and recycle material by safe methods, dispose of waste by suitable techniques, forbid the transfer of waste to developing countries, and raise awareness of the impact of waste. No single tool is adequate but together they can complement each other to solve this issue.
