How China is coping with its piles of abandoned shared bikes [Copy link] 中文

The boom and bust of bike-sharing in China have left one indelible legacy: Scrapped shared bikes.

In early 2018, mountains of old, scrapped shared bikes were seen piling up in street corners across major cities in China. Many had broken locks, some with their pedals or baskets stolen, though the main body of the bikes remained intact.

It is estimated that by 2020, at least 10 million shared bikes in China would be declared beyond repair, producing around 160,000 tonnes of solid waste. The latest generation of shared bikes, those with digital locks, contain hazardous lithium-ion batteries and circuit boards that may pose a danger to the environment if left unattended for years.

Seeing the magnitude of the problem, leading bike-sharing companies are partnering up with recycling firms to clean up piles of scrapped shared bikes.

Hellobike, a bike-sharing company backed by Ant Financial, told CGTN in an email interview that it collaborated with certified recyclers to dismantle key components of its out-of-commissioned bikes, including the seats, baskets, and wheels of the bikes. The main frames of the bikes, on the other hand, are used for the extraction of metals.

By the end of June 2019, more than 500,000 wheels, 250,000 baskets and 70,000 seats of its bikes are recycled, according to Hellobike.

Mobike, China's leading bike-sharing company, said earlier this year that it had already recycled nearly 1.5 million tires and 10,000 tonnes of scrap metal.

The number of abandoned scrapped shared bikes, which peaked in the year of 2018, is indeed on the decline, said Shao Yu, vice president of a recycling company responsible for dismantling shared bikes, in an interview with CGTN. He requested not to reveal the name of the company citing confidential agreement with his bike-sharing partners.

According to Shao, about 95 percent of materials in shared bikes are recycled. Most of the components that can be reused are already taken out by bike-sharing companies before they are sent to the recycling plants.

In the recycling plants, circuit boards in the digital locks are taken out and would be sold to certified recyclers for further processing. For the rest, the main body frames would be dismantled, from which aluminum, iron and steel can be extracted.

"Bike-sharing companies now have better ability to regulate the bikes, for example, placing the shared bikes only in densely populated areas, and charging users extra fee for leaving bikes in less populated area," Shao told CGTN.

If bike-sharing companies can produce bikes that are designed to be durable and rebalance the fleet of deployed bikes and the number of maintenance personnel, the recycling rate of shared bikes can be higher, he added.

In 2018, major cities in China started to cap the number of shared bikes in the cities and making it compulsory for shared bike companies to renew their bikes every three years. Beijing started to require bike-sharing companies to share data of the number, location and status of shared bikes with the local transportation bureau.

Big recycling companies now have virtually unlimited capacity of processing scrapped shared bikes, according to Shao. Nearly the entire dismantling process is conducted by automation: body frames of shared bikes are processed by dismantling machines, iron and aluminum are mined through magnetic separation.

Only the very last step of the dismantling process - separating the chemical elements of magnesium from the rest - requires human labor.

"We can process up to 1,000 tonnes of shared bikes every day and only 20 to 30 people are required in the dismantling process," Shao told CGTN.

It remains unclear which side, the bike-sharing company or the recycling company, will shoulder the cost of moving the shared bikes from the junkyard to the recycling plant. The logistics cost can be a hefty figure, since labor costs are on the rise.

As the whirlwind of shared bikes swept through China, it is time to deal with its aftermath. As Shao Yu puts it, "recycling scrapped shared bikes is a valuable social enterprise, not only because the shared bike junkyard is a sore to the eyes; it can be a huge waste of resources if left unattended."

"it can be a huge waste of resources if left unattended"

What a mammoth wastage of humand and physical resources has been ploughed into these mountains of disgarded bikes. Weren't bicycles once a ubiquitous symbol of Chinese culture ? And now even more time and energy is going to be placed into recycling the old bikes - to make more things which will again go to waste ? It's like throwing money into the river.

Recycle the bikes for various activities or into dust for producing other saleable objects. Obviously not thinking hard enough.

This same question can be posted country wide for the students to debate on. This will create healthy awareness of forward planning and fostering creativity. Yes someone created a good idea but that good idea eventually turned out not so good.

When the students are asked to think, first it teaches them to focus on solving the problems rather than blaming the past. Past has already happened and it won't change. The future can be guided if we think carefully. Of course along the way they can think of ways to discourage people from popping out with ideas that starts by looking good but ends up not so good.

Second they can have countrywide competition amongst the vocational students in bike modification competition.

Third, still a country wide competition by offering tertiary students only the chance to market and sell this globally - its a question of sharing rewards with them. let them forge teamwork in conjuring marketing ideas etc. and be exposed to entrepreneurship etc. Some of these people like to travel, get them to travel to lesser places as well not always frequenting high end places so that they can feel the global pulse and this will help them excel in the working environment in future. Currently only well to do students get to travel. Allow the poorer students opportunities to make some money. The minority ethnics should be involved in this together with the majority ethnic to foster closer teamwork. For example a marketing technique may be in the assistance of company to promote its products which involves the use of these bikes. E.g. like running marathon, one can have cyclethon or something like that with advertising impact.
