The disadvantages of plastic raw materials for plastic bottles

In the last two years, plant plastics made from corn or sugar cane have become very popular. Plant plastics can be broken down into water and carbon dioxide in the nature through the action of microorganisms. Some plastic bottles are now beginning to use plant plastics. Some scientists predict that it is expected that plant plastics will completely replace petrochemical plastics within five years.

However, "Scientific American" recently published an article that painted a question mark on the environmental impact of plant plastics. The article points out that the application of plant plastics is not as easy as it looks. Recently, Philip Lee recalled a batch of SunChips bags made of plant plastics. The recall was not due to safety issues, but because consumers complained that the sound of these plastic bags when folded was very ugly. ShellHuang, a packaging material developer at The Coca-Cola Company, pointed out that the production steps of Coca-Cola's PlantBottle polyester plastic bottle packaging are actually the same as other ordinary plastics. Currently, this kind of processing method is a cost that the merchant can afford, and partially uses the plant. The manufacture of packaging materials reduces the dependence on petroleum, and the long-term development goal is to strive for the use of plant wastes, such as sugar cane stems, cellulose in the leaves, lignin to make plastics.

The same problems exist with plant plastics and plant fuels, which directly or indirectly affect food production. In order to provide raw materials for plant plastics and vegetable fuels, large-scale planting of sugarcane will inevitably occupy a large amount of land for the cultivation of other food crops. This poses a threat to food production. From this perspective, plant plastics are not "green". Like polylactic acid, such plastics can be degraded but cannot be recycled. Although the prospect of the development of plant plastics production costs can be reduced, but the current cost is still very expensive.
