Can plastic bags be decomposed

Traditional plastic bags can't be broken down naturally. Eco-friendly plastic bags can be degraded by water, air, sunlight and organisms. Usually about a month, it can be decomposed into harmless substances.

Waste plastic with landfill will not only occupy a large amount of land, but also the occupied land will not be restored for a long time, affecting the sustainable use of land. Moreover, plastic bags to oil as raw materials, not only consumes a lot of resources, but also can not be decomposed, buried in the ground will pollute the land, rivers.

Plastic heat resistance and other poor, easy to aging, easy to burn, burning toxic gases. For example, polystyrene combustion produces toluene, a small amount of this material will lead to blindness, inhalation of vomiting and other symptoms, PVC combustion also produces hydrogen chloride toxic gases, in addition to combustion, that is, the high temperature environment, which will lead to the decomposition of the plastic toxic components, such as benzene ring, etc., causing pollution to the environment.

Plastic bags are slow to decompose, and are often piled up in ditches or riversides, preventing drainage and causing floods, destroying the ecological environment of the intertidal zone between the river and the sea, and causing ecological havoc if they are washed into the ocean in large quantities.

Modern plastic products, with a wide range of uses, low prices, easy to obtain, easy to use and other characteristics, so in daily life is a large number of applications. According to the environmental protection department statistics, Taiwan's annual consumption of plastic bags about 10.5 tons, of which about 6.5 tons of shopping with a total of about 20 billion, an average of 2.5 plastic bags per person per day, the majority of people with a time that is thrown away, become environmentally friendly garbage.

In view of the abuse of plastic bags on the environment, the environmental protection department many years ago to implement the policy of restricting the use of plastic bags, shopping plastic bags used to reduce the amount of about 80%, the public's willingness to provide their own shopping bags also increased.

Unfortunately, the lack of consistent implementation of the determination before and after the fall of the "loud thunder, little rain", more than 80,000 snack bars, restaurants, most of the way back to the old way of providing free plastic bags, vegetable markets, plastic bags more flooded, so that support for the policy of limiting the public and the environmental protection of the people feel very sad.
