By Guo Wei, China Environmental News: According to a report on April 7, 2015, from China Environment Net, the Ministry of Environmental Protection has announced the release of the “Compilation of Advanced Technologies for Water Pollution Prevention and Control” (hereinafter referred to as the “Technology Compilation”). In the next phase, second- and third batches of advanced technologies will be published in due course, providing scientific and technological support for the State Council’s forthcoming “Action Plan for Water Pollution Prevention and Control.” It is understood that, in order to promote the social sharing and practical application of the technological achievements resulting from the Major Science and Technology Project on Water Pollution Control and Treatment (hereinafter referred to as the “Water Project”), the project has coordinated with the Ministry of Environmental Protection and the Ministry of Housing and Urban–Rural Development to assess the progress made since the first phase of implementation.

According to a report on the Shantou Daily website dated January 29, 2015, the Leidashi Municipal Solid Waste Sanitary Landfill is the only facility in the central urban area dedicated to the harmless treatment of household waste, handling approximately 1,350 tons of daily municipal solid waste generated by the city’s more than one million residents. Having been in operation for over a decade, the landfill is now operating at full capacity. To ensure that the daily waste produced in the central urban area can be promptly treated in a manner that meets environmental standards, the city plans to expand the landfill by developing a new site on the “Xiangshanwo” hillside to the southeast. According to the Municipal Urban Management Bureau, land acquisition for the expansion project has already been completed, with construction expected to begin in May this year.

According to a report on January 20, 2015, from the Science and Technology Daily website, China’s agricultural processing industry generates approximately 90 million tons of protein‑rich by‑products annually. Due to their high degree of denaturation, low solubility, and poor nutritional quality, these by‑products are often underutilized, resulting in significant waste of protein resources. The Jiangsu University research team involved in the National 863 Program project “Key Technologies and Development for Biological Conversion and Refinement of Low‑Value Protein Resources” has overcome critical bottlenecks, pioneered several key technologies, and developed a series of multi‑mode ultrasonic equipment. Notably, their work titled “Research on Key Technologies for the Efficient Enzymatic Preparation of Functional Peptides and the Development of Ultrasonic‑Assisted Enzymatic Hydrolysis Equipment” was awarded in 2013 by the Ministry of Education as a high‑level achievement.

According to a report from Dongbei Net in Hegang on January 19, 2015, reporters learned recently from the Sanitation Department of the Municipal Urban Management Bureau that, after two years of intensive construction, the city’s municipal solid waste treatment facility is now nearing completion and will soon be put into operation. It is understood that the city currently generates more than 1,000 tons of household waste per day, all of which has been disposed of through rudimentary landfill methods. The collected waste is dumped directly into abandoned open pits without any prior treatment, resulting in leachate and fermentation gases that severely contaminate groundwater, urban air, and surrounding soil. This not only disrupts the daily lives and work of nearby residents and organizations but also poses risks to public health and raises safety concerns.

According to a report on Xinhua Daily Online dated December 17, 2014, the stirring impressions of General Secretary Xi Jinping’s inspection tours in Nanjing and Zhenjiang over the past few days have yet to fade. Face-to-face exchanges and close‑range interactions have greatly uplifted the spirits of cadres and the general public. “Closely focusing on the glorious mission of taking the lead in building a moderately prosperous society in all respects and in basically achieving modernization, we must strive to build a new Jiangsu that is economically strong, prosperous for its people, environmentally beautiful, and socially advanced,” his words still resonate, and the responsibility weighs heavily on our shoulders. The only site General Secretary Xi Jinping visited during his inspection in Nanjing was the Jiangsu Provincial Academy of Industrial Technology, underscoring the paramount importance national leaders attach to technological innovation.

Scientists have successfully fabricated a molecular sieve membrane “thinner than a cicada’s wing.”
On December 12, a research team led by Researchers Yang Weishen and Li Yanshuo from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, successfully fabricated for the first time a molecular sieve membrane composed of nanosheets just 1 nanometer thick—only one-thousandth the thickness of a cicada’s wing, making it far “thinner than a cicada’s wing.” By contrast, conventional molecular sieve membranes are more than ten times as thick. These nanosheets are not only extremely thin but also feature highly ordered channels resembling “sieve holes,” enabling precise separation of hydrogen and carbon dioxide molecules whose size difference is merely 0.04 nanometers, thereby effectively retaining the latter. The resulting nanosheet-based molecular sieve membrane exhibits permeation flux and separation selectivity that are far…
