Shanghai implements garbage sorting: What type of garbage does food packaging belong to?

Garbage sorting is everyone’s due responsibility and obligation.According to statistical data, the average daily household garbage generated in Chinese cities is about 0.66kg ~2.62kg, with an average of 1.16kg.There is no rural statistics, if the same 1.16KG calculation, China’s population of about 1.4 billion, produce about 1.6 million tons of garbage every day.There are 30 days in a month, 12 months in a year, and that adds up to a total of more than 102 trillion tons of waste produced annually in the country.A trillion tons of garbage covers an area of millions of square kilometers. If the garbage is left lying around, it will not only increase the workload of the environmental protection department, but also increase the environmental pollution index. As time goes by, the cities we live in will be flooded by garbage.

The significance of garbage classification is as follows:

  1. Reduce the occupation of land

Some substances in the household garbage are not easy to degrade, so that the land is seriously eroded. The amount of garbage can be reduced by more than 60 percent by separating waste and removing materials that can be recycled and not easily degradable.

  • Reduce the pollution

At present, China’s garbage disposal mostly adopts sanitary landfill or even simple landfill, occupying tens of thousands of acres of land; And cause flies flying, sewage overflow, stink, serious pollution of the environment. At the same time, waste plastics in the soil can reduce crop yields; It is not uncommon for discarded plastic to be eaten by animals and lead to animal deaths. So recycling can also reduce the damage to the environment.

  • Turn waste into wealth

Four billion plastic fast food boxes, 500 to 700 million instant noodle bowls and billions of pairs of disposable chopsticks are used every year in China, accounting for 8 to 15 percent of household waste.One ton of waste plastic can be recycled into 600 kilograms of diesel oil. By recycling 1,500 tons of waste paper, the trees used to produce 1,200 tons of paper are saved. A ton of cans melted into a ton of good aluminum, 20 tons less aluminum mining.30%~40% of household garbage can be recycled, so we should cherish this precious resource.We can also use cans to make pen boxes, both environmental protection, and save resources.In addition, other materials in waste can also be turned into resources, such as food, vegetation and fabric can be composted to produce organic fertilizers; Waste incineration can generate electricity, heat or cooling; Tile, ash can be processed into building materials and so on.All kinds of solid waste mixed together is garbage, if they are separated will become resources.If we can fully tap the resource potential contained in the recycling of household garbage, Beijing alone can get 1.1 billion yuan of economic benefits every year.It can be seen that, recycling is the best way to solve the waste problem if the waste generated in the consumption link is classified in time.

According to Article 4 of Shanghai Municipal Household garbage Management Regulations, the classification standards are as follows:

  • Recyclables mean waste paper, waste plastics, waste glass products, waste metals, waste fabrics and other domestic wastes suitable for recovery and recycling;
  • Hazardous garbage refers to domestic wastes such as waste batteries, waste lamp tubes, waste pharmaceuticals, waste paints and their containers that cause direct or potential harm to human health or the natural environment;
  • Wet waste, namely perishable waste, refers to food material waste, leftovers, expired food, melon peel and fruit core, flowers and green plants, Chinese medicine residues and other perishable biomass life waste;
  • Dry garbage, that is, other garbage, refers to the recyclable, harmful garbage, wet garbage and other household wastes.

The specific classification standards of household garbage may be adjusted according to the level of economic and social development, the characteristics of household garbage and the needs of disposal and utilization.

Such as dried fruit, fried goods, potato chips and other food packaging bags belong to plastic waste, recyclable, food bags are produced using food-grade plastic film, generally more than two layers of composite material packaging bags.These waste plastic not only through manual screening and classification, but also through the process of crushing, granulation, modification and so on, into a variety of transparent and opaque plastic particles, and then according to the phase of classification, and finally become recycled materials and waste solid fuel for power generation.


The benefits of garbage separation are obvious.Sorting garbage and sending it to factories instead of landfills not only saves the occupation of land, but also avoids the pollution caused by landfills or incineration. It can also be turned into treasure.In this battle between man and garbage, people turn garbage from enemy to friend.Therefore, garbage classification and collection can reduce the amount of garbage treatment and save the treatment equipment, and then reduce the cost of treatment, reduce the consumption of land resources, can bring social, economic and ecological benefits.
