According the high energy consumption and pollution in foundry industry, the reason of high energy consumption and the source of the pollution were analyzed. Based on the analysis, for the sustainable development of foundry industry, some effective measures were suggested: defining the responsibility of all referred parties (governor and enterpriser); trying to save energy and protect environment from the source; reusing the waste scientifically.

The research on the resource utilization, environmental protection and the sustainable development problem has already become an important subject. To analyze the industrial sustainable development of characteristics of high energy consumption in Beijing, Huairou and Shijingshan districts of sustainable development test zone is selected as the main object. Research on the typical industrial enterprises of test zone, the characteristic of energy use of high energy consumption industrial enterprises is analyzed. The result shows that the Huairou and Shijingshan districts take the same feature of high concentration of energy consumption. In addition, to make a further research on waste heat recovery and water recycling and other energy saving programs implemented by typical enterprises, the technical and economic analysis is also contained. Continue to thoroughly explore the potential to make a foundation for industrial energy work of sustainable development test zone in the "Twelfth Five-Year" period.

The extensive construction of urban theatres in China has entered a period of prosperity, but there are many problems, such as high cost of construction, too large scale, too many facilities, too little use, and excessive energy consumption, etc. It is not only contrary to the green environmental protection and energy saving policies that are advocated in our country, but also not accord with the requirement of sustainable development. In this paper, through site investigations and analysis on the newly built theatres in China, the high energy consumption tendency and its main causes in theater construction and design are summarized. Also, some basic principles related to the design of the theatres and the problems to be concerned have been discussed, therefore the reference and guidance for the architectural design of green theatres in china are provided.

In the process of economic development, the consumption of energy leads to environmental pollution. Environmental pollution affects the sustainable development of the world, and therefore energy consumption needs to be controlled. To help China formulate sustainable development policies, this paper proposes an energy consumption forecasting model based on an improved whale algorithm optimizing a linear support vector regression machine. The model combines multiple optimization methods to overcome the shortcomings of traditional models. This effectively improves the forecasting performance. The results of the projection of China’s future energy consumption data show that current policies are unable to achieve the carbon peak target. This result requires China to develop relevant policies, especially measures related to energy consumption factors, as soon as possible to ensure that China can achieve its peak carbon targets.

As the world’s largest developing country, and as the home to many of the world’s factories, China plays a crucial role in the sustainable development of the world economy regarding environmental protection, energy conservation, and emission reduction issues. Based on the data from 2003–2015, this paper examined the green total factor productivity and the technological progress in the Chinese manufacturing industry. A slack-based measure (SBM) Malmquist productivity index was used to measure the bias of technological change (BTC), input-biased technological change (IBTC), and output-biased technological change (OBTC) by decomposing the technological progress. It also investigated the mechanism of environmental regulation, property right structure, enterprise-scale, energy consumption structure, and other factors on China’s technological progress bias. The empirical results showed the following: (1) there was a bias of technological progress in the Chinese manufacturing industry during the research period; (2) although China’s manufacturing industry’s output tended to become greener, it was still characterized by a preference for overall CO2 output; and (3) the impact of environmental regulations on the Chinese manufacturing industry’s technological progress had a significant threshold effect. The flexible control of environmental regulatory strength will benefit the Chinese manufacturing industry’s technological development. (4) R&D investment, export delivery value, and structure of energy consumption significantly contributed to promoting technological progress. This study provides further insight into the sustainable development of China’s manufacturing sector to promote green-biased technological progress and to achieve the dual goal of environmental protection and healthy economic growth.

Gas-permeable film can separate air and water, and at the same time, let oxygen diffuse from the air to the water through the film. An oxygen supply method using this film was investigated for the purpose of reducing energy consumption for wastewater treatment. The oxygen transfer rate was measured for the cases with or without biofilm, which proved the high rate of oxygen transfer in the case with nitrifying biofilm which performed nitrification. When the Gas-permeable film with nitrifying biofilm was applied to the treatment of wastewater, denitrifying biofilm formed on the nitrifying biofilm, and simultaneous nitrification and denitrification occurred, resulting in the high rate of organic matter and T-N removal (7 gTOC/m2/d and 4 gT-N/m2/d, respectively). However, periodic sloughing of the denitrifying biofilm was needed to keep the oxygen transfer rate high. Energy consumption of the process using the film in the form of tubes was estimated to be less than 40% of that of the activated sludge process.

Some issues in pharmaceutical therapies such as instability, poor membrane permeability, and bioavailability of drugs can be solved by the design of suitable delivery systems based on the combination of two pillar classes of ingredients: polymers and lipids. At the same time, modern technologies are required to overcome production limitations (low productivity, high energy consumption, expensive setup, long process times) to pass at the industrial level. In this paper, a summary of applications of polymeric and lipid materials combined as nanostructures (hybrid nanocarriers) is reported. Then, recent techniques adopted in the production of hybrid nanoparticles are discussed, highlighting limitations still present that hold back the industrial implementation.
