1. Expansion of urban scale and population growth
With the increase of population, the amount of garbage generated has also been increasing year by year. In general, the amount of urban household waste generated is positively correlated with population growth, that is, the amount of household waste generated increases with population growth. However, currently, the growth rate of household waste generation in most cities in China is slightly higher than the population growth rate, which implies the influence of other factors.
2. Improvement of residents' living standards
The living standards of residents are reflected not only in their living consumption level, but also in the variety and supply mode of market goods. The improvement of residents' living standards has brought about a diversification of lifestyles and a brand new consumption concept, greatly stimulating consumer demand. Disposable items in daily life, such as tableware, chopsticks, tea cups, diapers, lighters, etc., have become waste generated by current consumption. The growth of plastic products and excessive packaging have caused changes in the useful components and volume of household waste, resulting in changes in the content, density, and heat generation of combustibles and renewable materials.
3. Improvement of public environmental awareness
The public's environmental awareness belongs to social behavior norms and moral standards, which directly affect the amount and composition of household waste generated. By promoting environmental education and establishing environmental regulations, guiding residents to change their consumption and lifestyle habits, we can gradually achieve waste reduction, recycling, and reuse. With the increasing awareness of environmental protection among the public, the composition and amount of waste generated will change.
4. Improvement of Municipal Environmental Sanitation Management Methods and Enhancement of Level
The improvement of environmental sanitation and municipal management level will enhance residents' awareness of environmental protection, as well as strengthen the resource recycling awareness of enterprises, catering units and other waste generating units. From the administrative management level, it will increase the market rate of clean vegetables, advocate garbage classification management, promote citizens' hygiene habits, reduce excessive packaging, practice thrift, oppose waste, and reduce the amount of leftover food. Thus gradually increasing the recycling rate of renewable resources and reducing the amount of waste generated.
