In a giant building filled with dark and humid rooms, some 2 billion cockroaches are scampering around piles of food. This is not a scene out of a horror film, but an innovative business venture to help Jinan, a “small” city of 9 million in northeast China, deal with its overfull food waste. Jinan produces more than 6,000 tons of solid waste each day, and like most Chinese cities, 50 to 70 percent of it is food waste. To divert more organic waste from landfills, the municipal government partnered with the Zhangqiu District Food Waste Processing Center to use cockroaches to dispose of the 60 tons of food waste daily from district restaurants and companies as well as households in 40 waste-sorting pilot villages. The company is highly profitable as it gets the food waste for free from the city; and city then gives subsidies for each ton of food waste processed. The company also sells some 2,433 tons of dead cockroaches each year as animal feed additives. However, the small six-legged workers only devour some 100 tons of food waste per day even with expansion plans for two new factories, a mere 1.6 percent of the city’s total  waste. Cockroaches alone cannot conquer the city’s food waste challenge.

As an agricultural engineering professor, I was excited to visit and tour the farm village Houbali, in southwestern Shandong Province. I found myself standing among newly constructed high-rise buildings, a vastly different community than I had expected to encounter. A bicycle repair shop was setting up alongside other bustling businesses in the first-floor storefronts. Farm families occupied apartments in the upper floors and a beautifully landscaped park and playground were a short walk away. This neighborhood looked like a transplant from Beijing, but these modern buildings were a newly developed farm village surrounded by agricultural fields. The new buildings brought together the residents of four old, nearly empty or “hollow” villages.

In September 2018, the Jinghu District People’s Court in Wuhu, Anhui Province sentenced 12 people from the Pol Shin Fastener Company between four months and six years in prison for committing serious interprovincial environmental crimes in Jiangsu and Anhui in 2016 and 2017. The court also fined the automobile hardware manufacturer 10 million yuan ($1.48 million). The crime? Dispatching ships and trucks to illegally dump 2500+ metric tons of highly acidic pickling sludge from steel production. Sludge—semi-solid waste emissions from industries and municipal water treatment plants—is yet another tough water and solid waste pollution challenge China faces.

Blanketed by freshly fallen snow, mountains of the Teton Range loomed above as I explored the picturesque town of Jackson, Wyoming. A native Bostonian, I had no experience in the heart of the country, but that week I wasn’t the only outsider wandering Jackson’s icy streets. In November 2018, experts from all over the world gathered in Jackson to attend the Jackson Hole Center for Global Affairs Forum with one common goal: to identify the challenges and opportunities for coal communities worldwide as they transition their economies away from coal.  

For solar industry professionals in China, May 31, 2018, is a day that will live in infamy. At the beginning of 2018, Chinese domestic solar developers were riding a high after reaching a record 53 GW of newly installed solar capacity the previous year. Most sources projected this breakneck pace of new solar construction would continue through 2018. On June 1, 2018, however, the National Development and Reform Commission, Ministry of Finance, and National Energy Agency announced a new policy to lower the solar feed-in-tariff, halt subsidized utility-scale development, and implement a quota for distributed projects. Industry professionals refer to the infamous policy as “531” for May 31, 2018, the day that the solar industry ground to a temporary halt or “freezing point.”

Autonomous vehicles (AVs) are revving up in China. As part of the 2018 CCTV Spring Festival Gala, more than one hundred AVs swerved perfect 8’s on the Hong Kong-Zhuhai-Macao Bridge, showcasing Baidu Apollo’s latest AV technology. China is a latecomer to the automotive industry, but it is taking the wheel in autonomous driving technologies and electric and hydrogen cars, viewing the sector as an unprecedented opportunity to play catchup with the rest of the world (See China Environment Forum webinar on China’s new energy vehicle trends below). Companies in China and around the world want to tap into the lucrative autonomous technology market that could reach $2.3 trillion by 2030.

In Wuxi, a city 84 miles west of Shanghai, nearly 2 million residents had foul smelling green water coming out of their taps for a week in May 2007. Wuxi sits on the shores of Lake Tai, China’s third largest freshwater lake. And on that week in May, it experienced a perfect cocktail of industrial effluents, agricultural runoff, and sewage, which created a toxic cyanobacterial bloom, leaving 70 percent of the city’s water undrinkable. The Lake Tai incident was not an anomaly. Poor oversight and enforcement of water pollution regulations and standards has long left between 30 and 50 percent of China’s surface and groundwater undrinkable.

China’s war on pollution and goals to lower carbon emissions are noteworthy as the United States takes a back seat in the global energy transition. Cleaner air and low carbon efforts in China could significantly change the country’s environmental health story and contribute to global efforts to lower greenhouse gas emissions. However, China’s energy reforms look less green now than they seemed after Paris in 2015. While China’s rate of increase in CO₂ emissions has slowed and the share of renewables in its energy mix continues to grow, the Chinese government’s pursuit of clean air along its east has shifted more polluting and water-intensive coal-fired power development into the country’s west. To continue to lead the way in this “Asian Century,” China must further incorporate water-saving reforms into its energy and environment plans.
