Development of the collection system

Waste collection previously meant heavy lifting and many work-related injuries, but today bags have been replaced by bins or other types of containers, providing a better working environment. While the working environment has improved in many respects, there are still problems that the industry is working to resolve.

In many places, manual waste handling has been replaced by new technology and automated systems such as vacuum waste collection and underground container systems. Both of these systems are on the increase, particularly in the cities and in newly built areas. One advantage is that they do not require any heavy manual handling during emptying.

Vacuum waste collection is a fully automated system which reduces the need for transports, particularly in residential areas. There are two kinds of vacuum waste collection systems, stationary and mobile. The stationary vacuum waste collection system collects waste pneumatically in an automated vacuum system. This is then transported through underground tubes from the refuse chutes to large containers located in a terminal. These containers are collected by a hookloader vehicle. The mobile vacuum waste collection system also uses air to collect waste. A storage tank is positioned under each refuse chute. The tanks are connected together to a docking point through an underground system of tubes. The vehicle connects to the docking point for collection.

Underground container systems are another fast growing collection system. Containers placed underground reduce the need for space at street level. The temperature underground is relatively low, which prevents odours. The containers are emptied using a vehicle with loader crane. There are also underground containers that can be emptied using a front loader vehicle. Because underground containers hold larger volumes, the number of trips can be reduced.
