The “Great Pacific Garbage Patch” is estimated to be anywhere from 3,100 square miles to twice the size of Texas. You may be wondering how garbage dumped on land can make it to the ocean. Well, first of all, some garbage is directly dumped into the ocean. Secondly, as Scripps…

The significant role of new technologies in landfill development and management may surprise some. This is a science-based industry that employs civil and environmental engineers, chemists, soil experts, biologists, geologists and hydrologists to protect today’s environment while developing the sustainable waste management practices of the future. Various cross sections of…

For waste engineers, landfills are an ongoing challenge that require frequent measurement and the application of constantly evolving maintenance techniques. After all, once tons upon tons of waste accumulate the maintenance challenges take on a life of their own. Liquid runoff must be managed, gasses must be contained, and the…

According to El Haggar , selecting a site for landfill purpose is one of the very significant processes to reduce the negative impacts to the surrounding. In Malaysia, the landfill site selection process for the land which is owned by the federal government is done by the National Solid Waste Department. However, the…

Landfills have a layered structure of waste and soil. Each layer of waste that is added into the landfill is compacted which removes oxygen and excess moisture from it. This leads to the breakdown of products anaerobically which over the time produces methane gas. The release of methane and other…

Despite the landfilling has become the final option of the waste hierarchy defined by the EU waste directive (2008/98/EC), it is still expected to be applied in several cases because of the growing amount of solid wastes and a lack of suitable techniques to treat all kinds of wastes. But…

Landfill leachate is a complex mixture characterized by high toxicity and able to contaminate soils and waters surrounding the dumpsite, especially in developing countries where engineered landfills are still rare. Leachate pollution can severely damage natural ecosystems and harm human health. Waste management is a crucial point in developed and…

A wide variety of wastes from industries, residences,and municipalities have been and will continue to be disposed of on the land. Current practices range from simple of refuse on a readily available piece of property to controlled disposal of waste on designated sites which are designed to minimize the potential for contamination…

Improper disposal of municipal solid waste has led to numerous environmental concerns like air, water and soil pollution. This requires immediate attention to minimize impact of municipal solid waste on environment and health. Most of the municipal authorities in developing countries are facing huge challenges to manage the municipal solid…
