At present, China is involved in garbage management, and the common technologies mainly include the following:

1. Biodegradation technology: using microorganisms to degrade garbage, producing reusable resources such as organic fertilizers or biofuels. The advantages of this technology are high processing efficiency and low cost, but there is a problem of generating harmful gases and liquids during the degradation process.

2. Incineration technology: The waste is incinerated and the heat generated can be used for energy utilization such as power generation or heating. The advantages of this technology are high processing efficiency and good capacity reduction effect, but there is a problem of generating a large amount of harmful gases and residues during the incineration process.

3. Stabilization technology: Stabilize harmful substances in garbage through chemical reactions to reduce their harm to the environment. The advantage of this technology is stable processing effect, but there are problems such as long processing cycle and high cost.

4. Sealing technology: Sealing garbage in underground or ground storage containers to reduce its impact on the environment. The advantages of this technology are simple operation and low cost, but there is a risk of leakage and contamination during the sealing process.

Overall, the main problems with domestic landfill treatment technology are incomplete treatment of harmful gases and liquids generated during the treatment process, low treatment efficiency, and low resource utilization. Therefore, it is necessary to develop more efficient and environmentally friendly governance technologies to solve the garbage problem.

Technological innovation has driven technological innovation in waste management. The comprehensive sorting, regeneration, and disposal technology for stale waste is developed based on the basic principles of solid waste treatment in China - "reducing capacity, harmless treatment, and resource utilization", with "fine screening" and "combustible material regeneration" as the two technological cores. After screening, it can be reused for garbage recycling, and after harmless treatment of the screened soil and sand, it can be used as farmland soil or backfilled. Combustible materials can be washed with water on site, avoiding the controversial process of garbage incineration and reducing the disposal costs of packaging and transportation. After granulation, plastic waste becomes economically beneficial.
