It was announced by the Bureau of City Appearance, Environment and Sanitation of the Guangzhou Municipality that the Jinshazhou No. 1 and 2 Closed Household Garbage Collection System was recently inaugurated. The project is composed of two central collection stations with the main collection pipe running a total distance of 2400 meters. A total of 50 tons of collected garbage passes for the pipe, and the total investment for the project is RMB 26.08 million. The project is expected to be completed by the end of next year. Once the four systems of the project havie been completed and put into operation, the Jinshazhou Closed Household Garbage Collection System will become the world's largest and will boast the largest processing capability.

Additionally, the Jinshazhou System, another closed garbage collection system is in the preliminarily planning stage and is to include such new urban areas as the Core Area of Zhujiang New City, Phase I of Guangzhou New Urban Area, and Luogang New City. Guangzhou urban areas are stepping into an age that makes garbage "invisible".

The Jinshazhou No. 3 Closed Household Garbage Collection System has been put into use in low-rent new communities. Outside each building, there is a sheet iron opening where citizens can put their garbage. For each garbage insertion opening, there is a connection to a pipeline through which the garbage will go to arrive at a central collection station less than 1.5 kilometers away. The system utilizes air power and the whole process takes less than 30 seconds from the computer controlled "drain valve" and exhaust fan to the arrival of the garbage at the green storage tank. Disposed materials travel at a speed of 40 to 70 kilometers per hour thus have no contact with the outside world, all one might sense is the sound of air pushing the refuse to the collection point.

The Bureau of City Appearance, Environment and Sanitation of the Guangzhou Municipality said that, compared with the traditional human collection method, the closed garbage collection system moves the collection process from above-ground to underground, from exposure to all to a closed and more hygienic system and from manual collection to an automated collection system, all of which, to a greater extent, avoids the well known disturbances of odors, mosquitos, rats and ants, reduces risks of spreading diseases and improves the environment.
