In recent days, the most striking is undoubtedly Beijing Winter Olympics. Green Winter Olympics is an important concept of the Beijing 2022 Winter Olympics, with a large number of environmentally friendly elements, such as cutlery, plastic bags, packaging bags.
Among them, biodegradable tableware is produced by fermentation of raw materials such as corn, potatoes, crop straw, etc., and further purifying high purity polylactic acid prepared by polymerization as raw materials. Compared to conventional petroleum base materials, the polylactic acid can be reduced from about 3 tons of carbon dioxide. Further, a large amount of greenhouse gas is discharged from the raw material to the polymer production process compared to the ordinary plastic, the carbon emission of the polylactic acid to the polymer production process is about 1/3 of the general plastic polyethylene.
Plastic bags are essential for life, compared to common degradable plastics, the plastics used in winter boiler have better thermal stability, mechanical properties, making plastic bags more durable; and excellent biodegradability, in compost conditions It is possible to completely degradation into water and carbon dioxide, which can effectively reduce white pollution.
In addition, Winter Olympics has caused a lot of discussions on the network. The Beijing Winter Olympics and Winter Disapprove Olympics Uniform Equipment is also practicing green environmental protection and sustainable concepts in designing, production, distribution and other links. For example, the yarn used by the equipment storage bag is the environmentally friendly yarn produced by the recycled plastic product; the packaging bag is made of biodegradable mother particles, and the 180-day resolution rate can reach more than 90%.
In fact, not only Winter Olympics, now, there are many degradable, low-carbon rosewats have already boarded the supermarket shelves and become a plastic substitute for many families. Of course, for environmentally friendly, compared to disposable utensils, sustainable tableware, canvas bag, etc. is preferred.
