- Description of technologies and equipment:

 The new system includes garbage tubes from each floor, with garbage inlet, outlet and garbage dumpers internally etc Unlike previously, this system has ventilated sections, cleaning pipelines that there is no accumulation of garbage clinging to the inside of pipelines. The sealed collection door can not endanger the sanitation workers working below pipelines. The cost of manufacture, transportation and installation of this collection system is not only much cheaper than imported products, but it is also consistent with the conditions of domestic production, easy operation, ensuring urban landscape.

More importantly, the system has closed collecting door that minimize the environmental pollution during operation; it can simultaneously coordinate with the architects and engineers during the design and construction for in sync the system of discharge, collection and transportation of waste with the high-rise apartment buildings from the start of design and construction.

This system has been received proprietary patent cerfiticate by Intellectual Property Department (Ministry of Science and Technology).

- Fields of application: Processing Environment
