) research background
There are a lot of second-hand bicycles parked on campus. Many abandoned old cars have flat tires and rusted, and their seats and cars are damaged.
There is no basket.
These second-hand bicycles not only occupy a lot of bicycle parking spaces,
It is a resource in itself.
Rational use of these resources will not only bring great social benefits to the society, but also beautify the campus and create a beautiful campus.

) research significance
Through the research and treatment of waste bicycles,
Will be able to effectively realize the recycling of resources,
Reduce resources
Waste. At the same time, it can reduce the pollution of waste bicycles to the environment and reduce the carport space occupied by waste bicycles.
Between. At the same time, it is convenient for students to travel and beautify the campus environment. Realize the concept of energy saving and emission reduction, and make waste
Bicycles have been used more fully and effectively.
If this scheme is popularized, it will save a large part of resources and protect the environment.
Establish a positive role. This will also contribute to the sustainable development of our country.

Summary of related research:
With the development of social economy, bicycles gradually fade out of people's sight and are replaced by batteries.
Cars and all kinds of motor vehicles. In this environment, many bicycles are abandoned, and many abandoned old cars.
It has a flat tire, rust, basket and seat. Faced with these, it not only occupies public resources, but also affects
Environmentally friendly used bicycles, we can't abandon them. The recycling of used bicycles has become today.
Social hot issues.
Chen Shengwei and Lu Jian mentioned Zhejiang forestry in Recycling Abandoned Cars: Making Bicycles Green.
Teachers and students of the college will make "green" bicycles after the abandoned cars of previous graduates are uniformly maintained.
Students obtain the right to use through application and other means. Teacher Xu Da of the college said, "If it can be handled well,
Bicycles abandoned by students are managed in a unified way, so that these resources can continue to play a better role, which
Sample can not only save resources, but also play a positive role in promoting students to establish the concept of ecological civilization. "

Wang Xiaoling,
Zhang Ling said in "Waste Bicycles Also Have New Selling Points" that Youguo Industrial Company is different from other recycling institutions, and it does not.
It is only a simple recycling business, but a "one-stop" operation of recycling, processing, leasing and sales. country
Youshang company regards recycling used bicycles as a kind of enterprise operation behavior with certain public welfare color, and through relevant measures,
History has truly achieved "taking from the people and using it for the people"

Reuse of old bicycles
It is expected to form a new industry.
》
Yes,
The school showed that
54
Products made by college students with second-hand bicycles,
Including street signs,
The podium,
Various works such as garbage cans tell us that products made of used bicycles should have corresponding practical prices.
Value, can meet certain production and living needs, in order to achieve recycling.

Xie wrote in the second-hand communication on campus
"Analysys Market Analysis" conducted II on students from four aspects: objective conditions of supply and demand, marketing methods, channel construction and trading methods.
The theoretical discussion on the second-hand market shows that the autonomy of higher education makes students pursue fashion, and the price of choice is relatively high.
Second-hand products,
survey shows that
60.7%
% of the students have bought second-hand goods.
according to
"The concept of sustainable development"
build
"ring
The concept of "environment-friendly, resource-saving society" and resource reuse has attracted more and more attention and recognition from students.
survey shows that
57.9%
% students think that buying second-hand goods can strengthen the reuse of resources and build the environment.

Where is the way out for recycling used bicycles?
Mentioned that the School of Mechanical Engineering of Tianjin University will dismantle used bicycles,
Modify and reuse,
Dozens of products are designed with full consideration of environmental protection,
Important factors such as saving materials and energy.
However, these products also have some defects that hinder the market. Because of this, companies and businesses with vision are more needed.
Economists cooperated with them to make the design more perfect. According to experts, compared with other raw materials, second-hand bicycles
Low recovery cost, high reuse rate and great utilization value. If there is a better design concept, there will be more.
Great social and economic benefits.

Liu Baoliang discusses in Remanufacturing Industry: Stumbling in the Absence of Standards.
The overall momentum of the remanufacturing industry is good. At present, the shortage of resources, energy and environmental load has become a system.
As for the bottleneck of global economic development, a large number of wastes have caused serious modern garbage pollution, resource waste and security risks.
Thanks to remanufacturing, the industrialization of high-tech repair and transformation of waste products has been realized, which is the embodiment of promoting comprehensive benefits of resources.
The overall momentum of the remanufacturing industry is good. At present, the shortage of resources, energy and environmental load is becoming more and more serious.
In order to restrict the bottleneck of global economic development, a large number of wastes have caused serious modern garbage pollution and resource waste.
And potential safety hazard. Remanufacturing has realized the industrialization of high-tech repair and transformation of waste products and is an important way to promote the comprehensive utilization of resources.
Effective ways of comprehensive utilization and environmental protection. Compared with manufacturing new products, remanufacturing can save energy.

It is environmentally friendly and practical to recycle used bicycles in Britain and provide them to pedestrians free of charge. They will waste
Old bicycles have been maintained by workers. These bicycles not only look like new, but also are safe.
Also meets the standards,
Pedestrians can use it with confidence.

The ingenuity of second-hand bicycles in strength training
In the wonderful application, the author made a fitness equipment with waste bicycles and steel pipes through ingenious ideas.
It is of great help to improve students' strength. Repeated practice in the teaching process has achieved good results.
Not bad either.

Skillful use of waste bicycle tires in physical education teaching
Discussed me in 3.
China is the kingdom of bicycles. Every year, tens of millions of bicycle tires are discarded because they are worn out, and very little is recycled.
It not only causes waste, but also causes environmental pollution. In many years of physical education teaching practice, the author insists on the principle of "improvisation"
The principle of "material and waste utilization" is to use waste bicycle tires in physical education teaching to enhance teaching interest.
Taste is of great help to improve students' physique.

According to the summary of relevant research at home and abroad, used bicycles and their parts are recycled and remanufactured.
After reaching the safety and quality standards, it can be completely applied to people's daily life, which is to promote the comprehensive utilization of resources.
And environmental protection. However, there is little research and analysis on the recycling of used bicycles in colleges and universities.
This topic combines the conclusions of domestic research on recycling of used bicycles with the actual situation of Jiangsu University.
Conduct research and analysis.
