On November 1, the 26th United Nations Climate Change Conference World Leaders Summit was held in Glasgow, UK. Speeding up environmental governance and actively responding to climate change is a common choice made by all human groups in the world. my country’s environmental protection work has made great contributions to the world’s environmental governance. The Beijing Winter Olympics Organizing Committee attaches great importance to the low-carbon management of the Beijing 2022 Winter Olympics and the Winter Paralympics, and actively introduces high-quality biodegradable materials and products, as Beijing 2022 The effective means of low-carbon environmental protection work for the Winter Olympics in 2008 also provided a boost for the development of the biodegradable industry in the market.
Biodegradable materials are currently widely recognized and vigorously developed "green ecological materials" in the current market. In theory, biodegradable materials can be transformed into carbon dioxide and carbon dioxide that are harmless to nature under the action of natural microorganisms such as bacteria, molds, and algae. water.
What kind of biodegradable material products has already appeared in the 2022 Winter Olympics?
1. Biodegradable tableware
In November last year, a domestic biodegradable material company signed a contract with the Beijing Winter Olympics Organizing Committee to become the official biodegradable tableware supplier for the Beijing 2022 Winter Olympics and Paralympics, helping the Beijing Winter Olympics to make improvements in the field of sustainable development. Great contribution.
Supported by the concept of "Green Olympics" and "Developing Olympics", the Beijing Winter Olympics Organizing Committee upholds the sustainability vision of "sustainability and the future". The use of biodegradable tableware in the preparation of the Games will help to draw on the benefits of the Winter Olympics. International efforts to amplify the positive impact of the environment.
The main raw material of the degradable tableware is the biodegradable material polylactic acid (PLA), which uses the crystallization properties of polylactic acid to make the product heat resistant to 120~130℃ through the self-crystallization behavior of the material itself, which far exceeds the most common in the market. Polystyrene (PS) composite materials are fully comparable to polypropylene (PP) products.
In addition, compared with traditional plastic products, in the process of processing degradable tableware, incineration will not produce toxic and harmful gases to pollute the atmosphere; landfill will not occupy a large amount of land for a long time, causing white pollution, land pollution and other problems; the processing process does not require pre-treatment. Sorting simplifies the treatment process and saves the cost of human resources; when the compost is buried for 6 to 8 months, it can be metabolized by microorganisms in the soil, and finally degraded into carbon dioxide and water that are harmless to nature.
2. Biodegradable plastic bags
According to media reports, in September 2021, a branch of Sinopec Corp. donated 100,000 biodegradable plastic bags to Zhangshanying Town, where the Yanqing competition area of the Beijing 2022 Winter Olympics is located. They are mainly used for venue services and residents’ needs. The measures will help reduce "white pollution" during the operation of the event.
According to reports, the degradable plastic bags donated this time are made of PBAT biodegradable plastic. Compared with traditional non-degradable plastics, this plastic not only has better thermal stability and mechanical properties, making plastic bags more durable; it also has excellent biodegradability and can be completely degraded into water and carbon dioxide under composting conditions. It is the mainstream degradable material in the current biodegradable market.
3. Biodegradable packaging bags
The design, production, and distribution of uniforms and equipment for the Beijing 2022 Winter Olympics also implement the concept of sustainable development of green and environmental protection: the yarn used in the equipment storage bag is to recycle waste plastic products to produce environmentally friendly yarn; The packaging bag is made of biodegradable materials, and the degradation rate can reach more than 90% in 180 days.
The quality of the natural environment involves the quality of life and living conditions of all mankind, and increasingly prominent environmental issues have become the focus of global attention. Gugebao Technology believes that climate change is a serious and urgent threat to human survival and development. All social forces should actively respond to the call of the policy and work hard to participate in it, so as to form a joint force to improve the current negative impact of human economic activities on the natural environment.
