Except for some non-degradable bio-based materials, biodegradable plastics are generally compostable plastics, that is, they are not recycled.

First, the EU is worried that the comprehensive promotion of biodegradable plastics will mislead consumers into thinking that the overall social development trend is still following the old path of disposables. Although the biodegradation industry does not encourage littering, and biodegradation does not have to be a product that can be thrown away after use, it is easy to mislead consumers if it is not guided. Many people think that biodegradable products will disappear when they are thrown away, which is very environmentally friendly. In fact, the biodegradation industry does not advocate littering, but instead promotes composting with kitchen waste to feed back agriculture.

Second, in order to be able to degrade quickly within half a year, most biodegradable products are designed to have a short service life and rapid deterioration of mechanical properties. Not only can they not be recycled (because they are biodegraded), but they are also mixed into traditional plastics. Plastic recycling. The European Union advocates recycling and reuse. If biodegradable materials are only suitable for disposable products, such as disposable clothes, disposable water glasses, and disposable tableware, although the products can be biodegradable, they do not meet the multiple-use concept advocated by the European Union . Of course, some bio-based non-degradable materials do not have this problem.

Third, at this stage, the cost of biodegradable materials is still high and consumes a lot of resources. If a large number of products are disposable after use, it is not economically feasible and has the disadvantage of not being resource-intensive. Therefore, the European Union is worried that the large-scale development of bioplastics will affect the implementation of resource-intensive development strategies. The earth is so big, and there are only so many resources. We need to save resources, which is in line with the development trend of human beings.

Therefore, the deep meaning of the EU Framework is that the development of bioplastics should not affect the construction of a resource-intensive society. What the EU opposes is not biodegradable plastics, but the waste of resources.

In fact, not only should bioplastics, biodegradable materials, and compostable plastics not affect these three items, but they should also actively allow these three items to play a major role in plastic pollution control. Because the problem of plastic pollution is mainly the "stock problem", that is, there are already billions of tons of traditional plastics that have been discarded in nature. There is still a need for people who tie the bell.” This kind of pollution must be solved by the traditional plastic industry through reduction, recycling, and reuse.

In addition to solving the stock problem of plastic pollution, human society should also think about how to solve the "incremental problem". By 2050, the world's population will increase to 10 billion, and the amount of plastic used may double from the current 450 million tons per year. Can these problems be completely solved by relying on the above three means alone?

According to data released by the European Union, compared with 58% for paper and 90% for steel and steel, only 14% of the 70 million tons of plastics consumed in the EU each year are recycled. And nearly 1/3 of the plastic packaging does not enter the recycling system, but flows directly into nature... As long as the EU raises the plastic recycling rate from 14% to 24%, it will reduce 7 million tons of plastic pollution. In this case, increasing the recycling rate will obviously immediately reduce plastic waste pollution, but is there a way to increase it to 34%, 44% or higher? The EU is also well aware that this is clearly not realistic.
