Waste Concrete

In the process of urban development, with the reconstruction of old city, a lot of waste concrete will be generated. At the same time, civil engineering construction, earthquakes and wars also can generate a large number of waste concrete. The existence of waste concrete will directly pollute environment and occupy the land resources. The recycling utilization of waste concrete is benefit to environmental protection and saving resources, and is also benefit to realize the sustainable development of building materials. Waste concrete research situations in China and abroad were introduced. The crushing and regeneration technology of waste concrete were studied. The material properties of recycled concrete were analyzed and some advices about development of recycled concrete in China were presented.

With the rapid development of urbanization in China, people’s requirements for the quality of life and environment are constantly improving. However, the shortage of resources and the deterioration of environment are becoming more and more serious. Environmental protection has become the only way for the sustainable development of society. Therefore, the application of more and more new green building materials has become the key to the sustainable development of the construction industry. In the face of the rapid development of modern construction industry, engineering quality and functional requirements have become the basic requirements, the green environmental protection has become a higher requirement. The application of green environmental protection building materials in engineering construction is the main development direction of the transformation of modern construction industry. At the same time, it conforms to the policy of environmentally sustainable development of all sectors of society, and promotes the construction industry to meet the higher requirements of green environmental protection living environment. This paper studied the performance and waterproof mechanism of a kind of high polymer (HDPE) self-adhered waterproofing membrane and its application in construction. Compared with the traditional waterproofing membrane, the high polymer self-adhered waterproofing membrane can give full play to the advantages of environmental protection on the premise of meeting the building quality.

Chinese Manufacturing Industry

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.

Land carrying capacity is an important indicator to quantitatively assess and judge the extents of sustainable economic developing and coexistent harmonizing between human and nature. The significance of land carrying capacity has been highlighted recently by the Sustainable Development Goals (SDGs) of the United Nations, which set clear requirements for arable, construction, and ecological lands. Theories and models of land carrying capacity, however, are suffering from the interference of artificial parameter setting and poor applicability. This paper attempts to overcome these limitations and propose a single factor assessment of the carrying capacity of cultivated land, construction land, and ecological land in terms of the relative carrying capacity from the perspective of a single factor assessment. Through mutual comparison, we found that the deviation caused by simulated parameter setting has been eliminated, and the relative status of each province and/or region in China has been obtained, which could provide a reference for the management and utilization of land resources. We argue that China can achieve basic self-sufficiency in both space capacity and food production without placing pressure on the global sustainable development. The results also indicate that carrying capacity state of the advanced development areas such as the eastern coastal region is relatively poor, while the carrying capacity state of the western region is relatively good.
