What needs to be done first for the process design of garbage disposal?
Release time：2025 / 12 / 18
The process design of garbage disposal requires the design party and the owner to conduct research on the following information in advance: (1) garbage material properties (material composition, moisture content, etc.). (2) process ideas (selecting resource utilization route, fuel utilization route, or mixed route). (3) Potential market for resource-based or fuel based materials (based on local market analysis of the types of resource-based or fuel based materials and the potential market value growth of each type of resource-based material). After both parties have a comprehensive understanding of this information and reached a consensus, the goal of rationalizing, practical, and economical design of the process flow can be achieved.
From the perspective of the development of the solid waste industry, due to the lack of backend classification processing technology and facilities, the vast majority of regions are currently unable to achieve integrated management and operation of "front-end classification collection and transportation" and "end of pipe classification disposal". The relevant government needs to encourage the application of new and efficient technologies through policies in order to fill the gaps. In order to achieve a complete classified waste treatment model in the 3.0 era of the solid waste industry, including "residential classification and disposal", "front-end classified collection and transportation", "mid-range classified treatment", and "end of pipe classified disposal", the government also needs to help promote the construction of classified waste treatment industrial parks, coordinate various types of waste treatment, and improve the collaborative treatment capacity of existing facilities to fill the gap in technical and facility support for "front-end" and "end of pipe", ultimately achieving the goal of rational incineration and harmless landfill.
At present, the level of domestic garbage treatment plants varies greatly. The investment and operation of high specification garbage treatment production lines are based on efficient and durable process design and technical support, high investment in imported equipment introduction and site construction, strict and orderly post management and operation maintenance measures, etc., most of which require varying degrees of central and local financial subsidies. Before the 3.0 era, many waste production lines in China were completed by "mechanically copying" advanced foreign equipment or technology; In the 3.0 era, it is strongly advocated to carry out garbage classification and treatment work that is suitable for Chinese characteristics. Therefore, practitioners in the solid waste industry should focus on developing waste treatment processes and production lines with Chinese characteristics, pay attention to technological innovation, emphasize social output of ecological value, and try to get rid of or reduce dependence on subsidies as much as possible.
