Waste Handling and Transport

On October 9, 2011, in Solid Waste Management, by Sushant

When we talk about solid waste management, there are many aspects of how such waste needs to be collected, treated, disposed of and other aspects. Today all modern towns and cities are facing the challenge of handling growing amounts of solid wastes and efficient management of such wastes including handling and transportation which is a subject of elaborate planning and management of the local authorities.

Waste collection varies from country to country, region to region. The collection methods depends on the expanse of areas covered, the landfill areas the garbage needs to be transported to amongst other factors. Usually the local government arranges for the waste handling and transportation in most countries though in some places it is handled by private players. Again, in many rural areas of developing countries there is no formal waste collection method.

Waste Handling and Transport In some advanced countries including those in Europe a vacuum based system is used to collect the refuse through underground conduits known as Envac. Here the refuse is transported to a designated area through a vacuum pump system, eliminating the need for manual handling of garbage. Metro Taifun is another vacuum based solution of single or ring line systems.

In many cities such as in Canada wastes are collected from the curbside in neighborhoods. Here the garbage bins are designated as wastes or recyclable materials and people are encouraged to segregate their waste before they drop them into the bins. These are then collected based on a daily schedule. In rural areas people need to transfer their garbage to a transfer station from where it is transported to a landfill area.

Many Asian countries face problem of huge volumes of solid waste management. In many such countries such as Taipei, the government charges taxes as per the volume of garbage produced and issue garbage bags in which the waste needs to be collected and deposited by the city people. Such initiatives have helped to reduce the waste accumulation and encouraged people to recycle and reuse.

The ArrowBio system is commonly used in many countries such as Australia, Greece, Mexico, UK or California. Here the trash is collected in trucks and by mechanical methods such as gravitational screening, settling and hydro mechanical shredding. Huge volumes of wastes are segregated, salvaged for recyclables and then turned into biogas or compost.

Thus, different countries and cities have different means of collecting wastes and transporting it but it still remains a huge responsibility on the civic authorities and they need the active help of the public in the growing waste management issues.
