If the foam dishes are ecological or not?

Pollution Theory: Foam crockery is difficult to degrade and can cause "white pollution" and Freon harms the ozone layer.

In theory, a disposable plastic foam lunch box buried in a hundred years to be degraded will lead to soil and groundwater pollution. And after recycling, it can no longer be used in food grade materials, it can simply be transformed into high quality industrial raw materials. But because of the food box will be attached to the edible oil, and the oil is not easy to clean, it is difficult to clean. This technical problem is not a major breakthrough, lunchboxes can not be processed after recycling. Therefore, from the point of view of current technology, the recycling of polystyrene foam is difficult.

The cooking agent of the lunch box is freon and the pollution of the environment still exists. At the present time, although the use of butane as a blowing agent, compared with Freon, is expensive, there may be illegal factories that use a less expensive but harmful environment for it. Blowing agent.

The foam dishes appeared on the train. Due to the waste of plastic waste, the Ministry of Railways has announced the ban on using the station's tableware and replaced with degradable dishware.

Theory of recycling: new technologies can reuse foam items

Experts believe that the first Freon PS foam to make a foaming agent, the ozone layer is harmful, but the current freon is an alternative to butane, will not cause damage to the atmosphere. To reduce the amount of polystyrene foam in the box and the "white pollution", recycling is essential.

Recycling plastic foam boxes such as Recycling polystyrene foam is very necessary to protect our environment. And we can then reuse it to make other products.
