"No waste" concept adds "green content" to Hangzhou Asian Games

What can a discarded milk carton become? Maybe a folding fan, a paper bag... In the Hangzhou Asian Games, such cases of turning waste into treasure abound, which is a subtle embodiment of the concept of "no waste Asian Games".

"Green" is one of the concepts of hosting the Hangzhou Asian Games, and "no waste Asian Games" is an important connotation of "green".

Cao Jiansong, the second-level inspector of Hangzhou Ecological Environment Bureau, introduced that "No waste Asian Games" is the first initiative of Hangzhou, which means that in the preparation process, the concept of "no waste" is fully implemented, the whole life cycle management of solid waste is strengthened, and the production of solid waste is minimized.

It is understood that Hangzhou has promoted the construction of 33 "waste free Asian Games" venues, 81 "waste free Asian Games" hotels, and 4 "waste free Asian Games" factories. At the same time, it has also built the application scenario of "no waste Asian Games" to achieve a management platform.

As a new concept, the construction of "no waste Asian Games" has no mature experience for reference, how did Hangzhou do it?

Hangzhou Asian Games venues adhere to the principle of "can be changed, not built", 44 of the 56 venues are rebuilt or temporary construction, and the other 12 new venues are fully considered for post-competition use. The Asian Games Squash Hall of Hangzhou Olympic Sports Center is temporarily rebuilt from the original 4D exhibition hall of Hangzhou National Expo Center, making maximum use of the original facilities and equipment.

The newly built Shaoxing Keqiao Yangshan Rock Climbing Center is transformed from an abandoned mine. After the game, it is planned to become a youth rock climbing sports base, and the temporary auditorium can also be flexibly adjusted according to needs, becoming a multi-functional venue for concerts and concerts.

At the same time, Hangzhou issued the Asian Games Green and healthy Building Design Guidelines and other standards, and actively promoted prefabricated buildings, renewable materials, etc., which greatly reduced construction waste. According to the data, after optimized design, the total amount of steel used by the "Big Lotus" stadium of Hangzhou Olympic Sports Center is 28,000 tons, which is about 1/3 less than the steel used by the stadium of the same size. Hangzhou Olympic Sports Center gymnasium, natatorium, Lin 'an Sports and Exhibition Center, etc., the light guide tube non-electric lighting system is used as daily lighting, and the annual lighting energy saving can reach 30%.

Straw-made hangers and toothbrush cups, the restaurant promotes small meals... In addition to venue construction, the Hangzhou Asian Games also adhere to the simple and low-carbon process of the event, and practice the concept of "no waste".

It is understood that in the Asian Games Village and the reception hotel, the Hangzhou Asian Games promotes clean vegetables into the village, centralized material preparation, on-demand processing, etc., to eliminate waste on the tip of the tongue. At the same time, the Hangzhou Asian Games also launched the "YunShangAsian Games Village" low-carbon account, encouraging "villagers" to obtain points and exchange prizes through CD-ROM action, garbage classification, non-plastic shopping, etc.

There is a "waste free house" in the athletes' village, where people can redeem their low-carbon points for prizes. "If you sort garbage once, you can get 10 points, and 50 points can participate in the twisted egg lottery." A staff member of the "No Waste House" told reporters, "one athlete directly drew a road punch board."

In addition to participating in the twisted egg lottery with points, you can learn a lot of low-carbon knowledge in the "no waste hut", and the furniture and furnishings here are also made through waste recycling. The "no waste hut" has become a beautiful scenery of the Asian Games Village and is the most popular place in the "village".

"The Hangzhou Asian Games follows the concept of running the games in a thrifty way. All kinds of equipment and equipment can be rented rather than bought or borrowed, and waste materials can be recycled as much as possible." Cao Jiansong said.

The wooden track of the track cycling hall of the Chun 'an Jieshou Sports Center is made of rented red pine wood splice, which can be dismantled after the race, and the venue can be rebuilt as needed. More than 5,000 seats in the original gymnasium of Hangzhou Dianzi University have been refurbished to become part of the Asian Games arena, minimizing the waste of resources.

In the sports and sports center of Zhejiang Industry and Commerce University, the venue for the handball event of the Asian Games, the original floor was dismantled for protection and then donated to schools in mountainous areas in need, and the utilization rate of the waste floor after renovation reached 80%.

The waste materials generated during the renovation and expansion of the venue are also recycled to the maximum extent. Li Shenfei, deputy director of the planning and Technology Department of the venue Construction Department of the Hangzhou Asian Organizing Committee, took the Ningbo Yafan Center as an example to introduce, "In the construction process of the venue, we will recover 760,000 square stones mined from the near-land land and backfill them into the sea for the construction of characteristic seawall."

It is understood that Ningbo Yafan Center's electricity is provided by 15 photovoltaic power stations to achieve 100% green electricity supply. In addition, more than 9,000 tons of construction waste generated during the reconstruction of the Huanglong Sports Center was also broken and classified, saving about 1 million yuan.

The Hangzhou Asian Games has also made an innovative use of corner waste. "We collect the scraps generated in the production process of mascots and make them into colorful mascots, each of which has a different splicing color and is a unique mascot." Cao Jiansong said.

In addition, the Chuansuo Museum in Yuhang District of Hangzhou also used waste wood and bamboo shoots to create a "no waste Asian Games" refueled duck, which became a "network celebrity" in the Asian Games Village and was loved by the majority of athletes. "We want to convey the idea of 'no waste Asian Games' to the public through this small' refueling duck '." Zheng Finan, director of the museum of transmission Shuttle, said in an interview with the Youth Daily.

"' No waste 'does not mean that there is no solid waste generated, nor does it mean that solid waste can be fully utilized as resources, but it promotes the formation of green development methods and lifestyles." Cao Jiansong said that since the successful bid for the Asian Games, Hangzhou has comprehensively implemented the requirements of green hosting games, and integrated the concept of "no waste" into the whole process of preparation, holding and post-competition utilization of the Asian Games. "At present, the 'Waste free Asian Games' brand with Hangzhou's recognition has been formed, showing the effectiveness of China's' waste free city 'construction to the world."
