Why there is a need for an underground waste system
An underground waste system is an infrastructure that makes use of the subsurface space to manage various waste streams in an efficient manner. An example is already set by utilities like electric, gas, water and sewage. The underground waste system can be a standalone collection system or it can be connected to an automated vacuum collection system where the transport of waste will be done through a pneumatic process. At the centralized facility, waste will undergo further processing.
The standalone collection system is more or less similar to the traditional system because the waste containers will be replaced by the underground collection points. Their inlets will be in the surface of the ground with a capacity that is similar to the dumpsters. One of the advantages of this standalone system is aesthetics and higher hygienic standards because odor problems are controlled. This type of underground waste collection is ideal for developing countries because there is minimal capital expenditure required and there is superior protection against vandalism.
The automated vacuum collection system is an unusual system of waste disposal because the tubes that are installed underground will suck waste pneumatically towards a central collection point. The system is a very attractive alternative because if offers a lot advantages. Aside from reduced congestion and emissions from garbage trucks, working conditions are improved in buildings because there is a reduction in the space necessary for waste disposal. Waste is no longer removed the traditional way since it ensures that waste is collected through tubes. This will speed up trash collection is dense urban communities and at the same time allow a smooth operation of the system even during difficult conditions like storms or even protest rallies. Waste handling is minimized compared to the usual collection methods.
Is vacuum collection system the future of trash collection?
An example of such a system can be found at Disney World where there is no trash that people will smell, see and touch. Disney World in Orlando, Florida is one of the more well known locations in the United States that are using vacuum collection systems in their underground recesses. As stated previously, the system has many advantages that can improve waste management and handling but it also has its drawback which is related to the high initial investment that is required to setup the system. The initial investment will be 30% to 50% higher than the surface collection system presently applied in many towns and cities. However, it is a viable investment due to reduced operating costs and the environmental advantages it can provide.
