China's Domestic Economic Belt

Less well known on the world stage than China's land and sea "One Belt, One Road" and "Maritime Silk Road" is China's Domestic Economic Belt along the Yangtze River from densely-populated and heavily-polluted Shanghai, west to the lake region around Wuhan (where COVID-19 originated), and still farther southwest to Chongqing, population over 30 million, larger than Shanghai and Beijing (home to OneSpace, China's solid-fueled commercial spacecraft industry, specializing in launching small satellites) and Chengdu, where police just raided an underground church about to commemorate the June, 1989 democracy demonstration in Tiananmen Square. (This is an opportunity for students to trace the Yangtze River on a map of China.)

Attention to ecology along this Yangtze River route is a priority in China. It entails:

•  Closing polluting chemical plants
•  Restoration of lakes and wetlands 
• Sewage treatment 
• Regulating the fishing industry
• Developing clean air technology (See earlier post,"How to Meet the Clean Air Challenge.")
• Integrating non-polluting energy sources into the existing power grid'
• Building new eco-friendly communities (See earlier post, "Priority: Eliminate generating electricity from fossil fuels.")

A new project in China's far western reaches demonstrates Beijing's focus on developing non-polluting energy sources. Where the Yangtze is known as the Jinsha Jiang River, the new Lawa hydroelectric dam will generate two billion watts of power, the same energy supplied by the U.S. Hoover Dam, on the border between Sichuan and the Tibetan Plateau.

     Development along the Yangtze also indicates China's interest in technological progress.  Economic assistance is going to the Donghu New Technology Development Zone east of Wuhan. The zone houses the FiberHome Technology Group, an optic fiber communications center, and the Wuhan Xinxin Semiconductor Manufacturing Corporation. Producing memory chips for China's semiconductor industry has become a personal priority of President Xi Jinping.

The U.S. Commerce Department's April, 2018 7-year ban on sales of chips to ZTE, the high-tech firm in China's integrated circuit and Smartphone industry, exposed dependence on exports from Qualcomm in California. Once again the consequences of cheating played a part. False statements and missing export records showed ZTE violated a 2017 settlement by illegally using U.S. chips in telecommunications equipment shipped to Iran and North Korea. Although ZTE had settled the 2017 case by paying a $1.2 billion penalty and promising disciplinary actions against 39 employees involved in illegal conduct, ZTE took no personnel measures. To restore Qualcomm's sales to ZTE, the company agreed to install a new management team and to let the U.S. staff a compliance unit that would report to the U.S. Commerce Department for the next ten years. At first the US Congress still rejected the plan, until President Trump and Chinese President Xi reached a separate agreement. 

Violations of the original ZTE technology agreement and other cases of Chinese infringement on intellectual property rights concern the U.S. about China's interest in stealing chip research, development, and manufacturing know-how, not only how work in these areas is progressing at the zone in Donghu. With nearly 350,000 Chinese students in the United States, universities are warned to lock their labs, and legal interns from China are being kept away from sensitive antitrust cases. (See the post concerning Foxconn's intended facility in Wisconsin in the later post, "Unmask Inscrutable Chinese Intentions.") 

China Tries to Build a Tree Wall

Rather than keeping immigrants out, China's new tree wall is designed to keep out the smog-producing sand and dirt that blows south into Beijing from the Gobi Desert.

     To combat pollution's health hazard and fossil-fuel causing climate change, China is employing a 3-pronged plan: 1) manufacturing electric cars and banning gas-fueled vehicles, 2) constructing towers to filter dirty air, and 3) planting a wall of pine and poplar trees.

Trees are the focus here, because electric cars powered by lithium batteries and air-filtering towers were the subjects of the earlier post, "How to Meet the Clean Air Challenge."

     Like the Sahara in Africa that even blows sand into Europe, the Gobi Desert expands into China, covering as much as 1,000 more square miles annually. Besides causing pollution, sand eliminates farming and livestock grazing land and closes roads and rail lines. By adding to the demand on groundwater and the loss of trees for firewood, population growth in Inner Mongolia, directly south of the Gobi Desert, also strips Beijing of any protection from wind blown sand. In both Africa and China, before close analysis, planting trees seems like a good solution to stabilize topsoil, absorb greenhouse gases, and even increase rainfall.

     According to an article in Mother Jones (August, 2017), Beijing's forestation efforts began in 1978 and accelerated as a government priority after 2000. Since then, up to 700,000 villagers have been forced off their family plats to make way for trees. By 2018, the government set ambitious planting targets: 32,400 new square miles worth of trees by the end of the year and an increase in the forested area of China's landmass from 21% to 23% by 2020 and to 26% by 2035. Villagers are paid to plant seedlings, and in 2018 armed police and 60,000 soldiers from the People's Liberation Army were reassigned from duty on the northern border in order to plant trees in Hebei Province around Beijing and the area where China will host the Winter Olympics in 2022.

     In response to the government's commitment to battle sand, the State Forestry Administration gained an incentive to claim the frequency of sandstorms decreased 20% between 2009 and 2014, rainfall increased almost six fold in 29 years, and a high percentage (60% to 75%) of new trees survived three years. By planting trees, running solar power fields, and attracting ecotourists, contractors, such as Wang Wenbiao, who heads the $6 billion Elion Resources Group, are making fortunes implementing these government programs. Wang also owns the Seven Star Lakes Desert Hotel and golf course which has a fountain at the entrance and a green lawn and grove of poplars.

Trees in the fast growing poplar genus include aspen trees that require an extensive root system to acquire the large amount of water desert conditions do not provide. Pictures of what are said to be poplars do not look as though they are growing the 3' to 5' annually that is expected.
     The smog reduction potential of China's electric cars, and maybe air filtering towers, seems to offer more promise than forestation.

How to Meet the Clean Air Challenge

Similar to the process of producing clean water, one method China uses to attempt to reduce chronic smog pollution moves dirty air through a filtration system.

     In Beijing, a Dutch invention cleans air using a 23-foot, cylindrical filtration tower powered by electricity from a coal-fired power plant. A 300-foot tower surrounded by coated greenhouses in Xian, Shaanxi province, is experimenting with a more complex process. In daylight hours, solar radiation heats polluted air in the greenhouses before it rises in the tower through a series of purifying filters and is released into a 3.86 square mile area. Thus far, the Xian tower, when treating severely polluted air, especially in winter when coal provides heat in the area, shows only a 15% reduction in the fine small particles most hazardous to health. Yet, Xian's developers have an ambitious plan to construct 1,640-foot anti-pollution towers, each surrounded by 11.6 square miles of greenhouses, in other Chinese cities.

     Based on the Australian study mentioned in the earlier post, "Priority: Eliminate generating electricity from fossil fuels," coal-fueled power plants are the major source of pollution. These air filtration towers would seem to do the most good, if they were located in the vicinity of power plants.

     Startups and traditional automakers throughout the world race to produce the electric cars that promise to eliminate a source of pollution, the fossil fuels that power today's cars and trucks. The challenge to up the percentage of electric passenger cars from less than 1% on the world's roads today to at least 33% by 2040 involves financing, designing, engineering, manufacturing, charging stations, searching for the lithium used in batteries, and marketing. China is the industry's acknowledged leader with Tesla in the U.S. and European automakers also in the hunt.

     Although China is expected to continue to import lithium from South America's Argentina-Chile-Bolivia Belt (See the earlier post, "Technology's Hard Sell and the Public's Role in the Lithium-ion Battery Industry."), it has its own domestic supply. In the cold, thin air high in China's mountains between the Tibet Autonomous Region and the Xinjiang Uighur Autonomous Region, mining in Chaerhan Salt Lake is on track to supply a plant that will produce 30,000 tons of lithium carbonate by 2020 or 2021 and eventually plants that produce 200,000 tons annually.

     China also has ideas for creating charging methods to keep electric cars on the road away from home. When driving long distances, drivers could visit automated swap stations to switch their dying batteries for new ones in three minutes, or they could call mobile vans to come and recharge their dying batteries in ten minutes. (I cannot help but recall the toxic nano particles a high school student found, when her summer intern project at the University of Wisconsin studied the effects of decomposing lithium batteries. See the earlier post, "The Challenge of New Technologies: Prepare to Think.") By requiring foreign auto dealers to sell only electric cars and to provide charging options, China is in a position to restrict entry into the world's biggest market.

   

     

Technology's Hard Sell and the Public's Role in the Lithium-Ion Battery Industry

New technologies require public acceptance and industry risk takers. What if consumers had refused to bring nuclear-powered microwaves into their homes or to let doctors use lasers to cure diseases? I've gained new respect for the physics teacher I had who assigned students to weekly reports on journal articles describing break-through scientific advances. Unless a country enters the world's economy late or a hurricane or earthquake destroys infrastructure, it is an uphill slog for a new technology to compete with entrenched technologies.

     Top executives recognize the challenge of creating a corporate culture, much less a public culture, attuned to welcoming technological change. At a recent conference, CEOs of 100 leading companies in 17 different industries concluded it is easier to incorporate rapidly changing technology into an existing system than it is to create a corporate culture willing to embrace technological changes.

     Consider the introduction of lithium-ion batteries. In the United States, electric cars using these batteries need to compete with existing cars, and they require charging stations to replace gas stations. As a clean energy source, huge lithium-ion battery packs that provide power to electricity grids need to compete with coal and natural gas. When a leak at California's Aliso Canyon natural gas facility forced the San Diego Gas & Electric company and Southern California Edison to try to provide Los Angeles and San Diego with electricity from grid-scale batteries, AES Energy Storage built a lithium-ion battery installation in under six months, compared to the years it takes to obtain permits to construct polluting power plants near heavily populated urban areas.

     Logic suggests car manufacturers and electric companies avoid "marketing myopia" by seeing themselves with a wide lens that positions them in transportation and energy industries that need to invest in up-and-coming alternatives. Companies are beginning to do just that. AES and Siemens now have a joint venture. California Edison is working with Tesla, known for manufacturing electric cars, and Mercedes-Benz and BMW also are involved in stationary power storage projects with utilities.

     Nonetheless, reliance on private investment limits the development and use of lithium-ion battery technology. Again, there is a role for teachers and students who take a realistic view of what fosters technological advances. Denying the effect of fossil fuels on climate change does nothing to encourage government investment in clean energy from lithium-ion batteries or tax relief for battery manufacturers. And how about government support for lithium exploration (top producers are Australia, Chile, Argentina, and China) and safe disposal of used lithium or, better yet, support for efforts to "mine" recycled lithium?

     In fact, Elon Musk claims all the nickel used in his Tesla electric car batteries is reusable at the end of a battery's life. If true, that is good news, because nickel mining, mainly in Australia, Canada, Indonesia, Russia, and the Philippines, kicks up sulphur dioxide and pollutes rivers with oxidized nickel waste. Dr. David Santillo at Greenpeace's research laboratories reports crushing and transporting nickel produces dust containing copper, cobalt, and chromium, as well as nickel, that causes respiratory problems and cancer. Rather than continue to mine poorer and poorer strains of nickel, Santillo suggests an effort to recover and reuse nickel already extracted.

     Wise young people need to focus on the new career opportunities new technologies present.

Dump the Dump

You can feel superior to those who throw plastic bottles into the ocean, flip lithium batteries into the trash, and buy new shoes instead of having a cobbler replace worn heels. But a close look at recycling finds even this "solution" has problems awaiting solutions.

     Making it easier for soda consumers to recycle plastic bottles or providing batteries with electronic tags to help pull them out of the ordinary disposal process still sends these bottles and batteries to a waste plant. The problem of disposing of the heavy lithium-ion batteries that wear out in the growing fleet of electric cars is a major matter of concern to these auto makers as well.  Waste plants, such as the Integrated Waste Management Facility at Bukit Nanas in Malaysia, boast about converting waste to electricity, but they downplay the cancer and other toxic disease emissions these plants produce. And what about the average annual rate of 300 fires at waste and recycling plants in the United Kingdom?

     In a recycling industry where price to cost margins are small, there is little incentive to monitor air quality frequently, purchase sprinklers and other expensive fire prevention equipment, keep from stacking recycled materials too high and too close together, provide employees with protective gear, or penalize and shut down illegal waste sites.

     "Repair rather than replace" has a nice ring to it, but when it is less expensive to buy new shoes or a small appliance than to have old ones repaired or even find someone who can do the job, those options aren't considered.

     Knee jerk solutions aren't always solutions. Substituting degradable paper bags and packaging for plastic that requires fossil fuel to produce and years to disappear can deplete forests. Reducing the amount of gasoline cars use by adding 10% ethanol from corn requires more electricity and might mean some people go hungry.

     When I was having a chair reupholstered, I also asked the man I called to do the repairs how much it would cost to recover a sofa chewed by the cat. He told me, "$600." I said something like, "I've seen new sofas advertised for less." He asked how old my sofa was, and I guessed about 60 years. He told me I wouldn't find anything like its interior materials and construction on the market today and that he's recovered furniture for people who go to yard sales looking for old furniture they can buy cheap, because they know the insides of these old pieces are worth the cost of upholstering them.

     Every time we are walking to the trash to throw something out, maybe we should slow down and ask ourselves: what could I do with this, who could use this, why did I buy this in the first place?
