Green Winter Olympics is an important concept of the Beijing 2022 Winter Olympics, requiring environmental protection requirements in terms of venues, technical support, energy usage. Winter Olympics has a large number of environmentally friendly elements, such as cutlery, plastic bags, packaging bags.
Biodegradable tableware
This biological degradable tableware is produced by fermentation of raw materials such as corn, potato, crop straw, etc., and further purifying high purity polylactic acid prepared by polymerization as raw materials.
Polylactic acid is a fully biodegradable biological new material representative, and is currently cost-effective biodegradable environmentally friendly polymer materials, compared to conventional petroleum-based materials, each ton of polylactic acid can reduce row of about 3 tons of carbon dioxide. This is because the polylactic acid has good biodegradability, and the microorganism is completely degraded to finally producing carbon dioxide and water. Compared to ordinary plastics, incineration is used, the carbon emissions of polylactic acid from the raw material to the polymer production process are about 1/3 of the general plastic polymer production process.
These degradable tableware, do not produce toxic hazardous substances during use and biodegradation, have certain degree of gas resistance, flame retardancy, and ultraviolet lineability, which can be described as healthy and safe.
Biodegradable plastic bag
In order to reduce the white pollution during the event, China's Petrochemical Beijing Petroleum has donated 100,000 easy brands to the place of Zhangshan Ying Town, Beijing 2022 Winter Olympics.
Compared to common degradable plastics, the plastic has better thermal stability, mechanical properties, making plastic bags more durable; there is excellent biodegradability, which can completely degrade it to water and carbon dioxide under composting conditions, which can be effective Reduce white pollution.
Biological degradation packaging bag
Beijing Winter Olympics and Winter Disapprove Assembly Equipment Equipment is also intended to practice green environmental protection and sustainable concepts in design, 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%.
