Free report may Waste Management

In recent years, the increasing volume and complexity of waste associated with the modern economy is posing a serious risk to ecosystems and human health. Every year, an estimated 11.2 billion tonnes of solid waste is collected worldwide and decay of the organic proportion of solid waste is contributing about 5 per cent of global greenhouse gas emissions. Of all the waste streams, waste from electrical and electronic equipment containing new and complex hazardous substances presents the fastest-growing challenge in both developed and developing countries. This is exactly where comes Waste Management.

Waste management is the collection and separation of solid and liquid waste. This separation is carried out either manually in bulk or mechanically by means of pumps, or by a variety of other machines. Solid waste from households, offices, factories, industries and transport is collected through landfills while liquid waste is collected from sewage systems. A solid waste is defined as an organic or inorganic substance which is regarded as waste . This can include household waste, organic waste from agriculture and forestry, industrial and household chemicals, garden waste, and municipal waste. A landfill is a type of disposal facility designed to dispose of solid waste in order to prevent the waste from contaminating surface and groundwater. Over the years, landfill sites have become increasingly complex. The increasing number of landfill sites, which are also known as "lagoons" or "dump sites", represents a serious environmental risk and a major threat to global climate change.

In the past, disposal of waste was limited to landfill sites and incinerators. In developed countries, there were few alternatives: incinerators—which were often too expensive, while landfill sites were not viable because of the high costs involved. However, the recent development of advanced waste management systems has allowed for a more efficient and economically viable disposal of waste. As a result, landfill sites have become an increasingly common sight in many developed countries.

Poor waste management, which includes everything from non-existent collection infrastructure to inefficient disposal, contaminates the air, water, and land. Open and unclean landfills can infect people, spread disease, and lead to the poisoning of drinking water. The spread of litter harms ecosystems, and hazardous materials from industrial waste or technological waste are bad for both the environment and the health of people.

The reduction of waste is the first step toward a solution. Where waste cannot be avoided, the second-best alternative should be the recovery of materials and energy from garbage as well as the remanufacturing and recycling of waste into useable goods. Recycling helps save a lot of resources. For instance, 17 trees and 50% more water can be saved for every tonne of recycled paper.

Waste management is the segregation of waste and recycling of waste, in order to optimise the use of resources. Waste management is a vital component of sustainable development, including the reduction of environmental pollution and resource consumption
