III. Comprehensive Utilization of Refuse

 

III.1 Actively develop the comprehensive utilization technology, encourage the recovery and utilization of waste paper, metals, glass and  plastics, and gradually establish and improve the recovery networks of waste materials.

III.2 Utilization of residual heat from refuse incineration, recovery and utilization of gas from land filled refuse, hightemperature compost of organic refuse and utilization of methane by anaerobic digestion shall be encouraged.

III.3 The secondary pollution shall be avoided and controlled in the course of recovering and comprehensively utilizing refuse.

 

IV. Collection and Transport of Refuse

 

IV.1 Actively carry out an activity of collecting refuse. The classified collection shall be combined with classified desposal and the classification shall be conducted in line with the method of disposal. 

IV.2 Collection and transport of refuse shall be conducted in a tightly closed way so as to prevent the refuse from exposing, spilling and dripping. The method of compression collection and transport is encouraged. The method of open collection and transport of refuse shall be eliminated as quickly as possible.

IV.3 Strengthen the collection, transport and disposal of massive refuse in combination with recovery and utilization of resources.

IV.4 No dangerous wastes shall be allowed to get into consumer waste. An independent system for collecting, transporting and treating waste batteries, fluorescent tubes and containers for pesticied shall be gradually established.

V. Sanitary Landfill Disposal

 

V.1 The sanitary land fill is an indispensable and ultimate means for refuse disposal and is also a major method for refuse disposal at present in China.  

V.2 The plan, design, construction, operation and management of the sanitary land fill grounds shall be implemented strictly in accordance with the requirements of the Technical Standards for the Sanitary Landfill of municiple refuse, the Standards for the Pollution Control of the Sanitary Landfill of municiple refuse  and the Environmental Monitoring Technical Standards for the Landfill Grounds of Consumer waste.

V.3 Scientifically and rationally select the sites for sanitary landfill grounds so as to be beneficial for reducing the impact of sanitary landfill on the environment.

V.4 If the natural conditions of the sanitary land fill grounds meet the standards, the natural leakage proof method shall be adopted; if the grounds fail to satisfy the natural leakage proof conditions, the man made technical measures for leak protection shall be taken.

V.5 Rain water and sewage shall be separately drained on the sanitary land fill grounds so as to cut down the amount of percolating water ( percolated liquid)  in the course of operation

V.6 A collection system for percolating water shall be established and drain the appropriately treated percolating water into the urban sewage disposal system is encouraged. If the above conditions are not satisfied, individual installations shall be established for treating the percolating water and only when the percolating water has been up to the standard, it can be drained into the water body.The percolating  water can also be refluxed so as to reduce the amount of treatment, cut down the treatment load and speed up stabilization of the sanitary land fill grounds.

V.7 A leading out and discharge system for the gases from sanitary land fill grounds shall be set up.
