Waste is any substance which is discarded after primary use, or it is worthless, defective and of no use. Wastes’ are substance or objects, which are disposed of or are intended to be disposed of or are required to be disposed of by the provisions of national law”. Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded.
There are many issues that surround reporting waste. It is most commonly measured by size or weight, and there is a stark difference between the two. On a global scale it is difficult to report waste because countries have different definitions of waste and what falls into waste categories, as well as different ways of reporting. 338 million tonnes of waste was generated in 2001. For the same year, OECD estimated 4 billion tonnes from its member countries. Despite these inconsistencies, waste reporting is still useful on a small and large scale to determine key causes and locations, and to find ways of preventing, minimizing, recovering, treating, and disposing waste.
Inappropriately managed waste can attract rodents and insects, which can harbour gastrointestinal parasites, yellow fever, worms, the plague and other conditions for humans, and exposure to hazardous wastes, particularly when they are burned, can cause various other diseases including cancers. Many of the environmental burdens cited above are more often borne by marginalized groups, such as racial minorities, women, and residents of developing nations. However, the need for expansion and siting of waste treatment and disposal facilities is increasing worldwide. There is now a growing market in the transboundary movement of waste, and although most waste that flows between countries goes between developed nations, a significant amount of waste is moved from developed to developing nations. The location of waste treatment and disposal facilities often reduces property values due to noise, dust, pollution, unsightliness, and negative stigma. This sector can significantly alter or reduce waste in a particular system, but other negative economic effects come with the disease, poverty, exploitation, and abuse of its workers. Resource recovery is the retrieval of recyclable waste, which was intended for disposal, for a specific next use.
It is the processing of recyclables to extract or recover materials and resources, or convert to energy. This process is carried out at a resource recovery facility. Resource recovery is not only important to the environment, but it can be cost effective by decreasing the amount of waste sent to the disposal stream, reduce the amount of space needed for landfills, and protect limited natural resources. There are several ways to recover energy from waste. Secondary recovered fuel is the energy recovery from waste that cannot be reused or recycled from mechanical and biological treatment activities. Pyrolysis involves heating of waste, with the absence of oxygen, to high temperatures to break down any carbon content into a mixture of gaseous and liquid fuels and solid residue.
Gasification is the conversion of carbon rich material through high temperature with partial oxidation into a gas stream. Using waste as fuel can offer important environmental benefits. There is some debate in the classification of certain biomass feedstock as wastes. Chapter III: Waste Quantities and Characteristics, 31-38. Solid Waste Management, Volume 2.
