Solid waste is defined as refuse from domestic, industrial, commercial or institutional sources, produced as a result of human activity.
It excludes wastes that are hazardous, radioactive or liquid.
Solid waste management is concerned with the creation, avoidance, reduction, collection, transport, processing, and/or disposal of waste materials.
Properly done, it will ensure that:
1.
there are minimal negative effects on human health;
2.
that any effect on the environment is manageable
3.
that natural resources are maintained;
Government authorities charged with following and guiding the environmental hearing process.
This has led to extra costs for applicants, and subsequent delays in decisions by the hearing .
The reasons for this constraint can include the desire of elected officials to avoid the wrath of angry voters on contentious solid waste management issues
Government can assist this process by providing greater certainty in the environmental assessment and approval process dictating the approach to identification, screening and selection, construction, and operation of a range of reasonable alternatives.
The ability of engineers, decision makers and the public to resolve solid waste management issues would benefit from a more definitive.
Engineers who have spent many years working on projects such as these believe that the following hierarchy for the management of solid waste should be used.
The residual waste still remaining, following each stage, would be considered for treatment in the next or succeeding stage.
1. Prevent waste generation where possible. 2. Reuse waste for other purposes. 3. Recycle waste through the creation of other useful products. 4. Compost the organic fraction of the waste stream and use the resulting composting material. 5. An aerobically bio-degrade the organic fraction of the waste stream to recover methane for energy and use the resulting biodegraded material. 6. Incinerate, change the form, and reduce the volume of the combustible fraction of the waste stream, and recover the energy, while safely disposing or using the products of combustion.
6. Incinerate, change the form, and reduce the volume of the combustible fraction of the waste stream, and recover the energy, while safely disposing or using the products of combustion. 7. Landfill waste in a safe location, using methane and other gases as a source of energy.
In order to determine the most appropriate solution, engineers follow a process that begins with defining the solid waste management challenge to be resolved,
In most cases, the product from a composting system can safely be used in the agricultural industry.
Landfills have systems in place to deal with any contaminant that prevents the use of the product in agriculture.
Methane that is released into the atmosphere can cause up to 20 times the damage to the stratosphere as the same amount of carbon dioxide.
Therefore, it is very important that methane emanating from a sanitary landfill be captured and burned off – either in a system using the gas’s energy, or simply flared off.
The production of glass from raw materials requires a great deal of energy.
