Current status and system construction of used-furniture recycling in China

Abstract

In order to promote the development of the green and low-carbon wood industry and explore the current status and trend of China's used-furniture recycling, this paper summarizes the research status of used-furniture recycling and interprets governmental strategies, such as the development of used-furniture recycling system, the way of handling used-furniture by manufacturers, and the attitudes of customers towards used-furniture, through extensive literature reviews and market researches. From such three respects as government, furniture manufacturers, and consumers, the problems of national used-furniture recycling are analyzed, for example, imperfect system, high cost and weak awareness. Therefore, to solve the above problems, it is necessary to construct national used-furniture recycling system and methods, including, for government, the construction of recycling network, the supervise and support of entrepreneurial responsibilities, and the formulation of recycling standards; for furniture manufacturers, the improvement of the durability and recyclability of furniture, the development of new models and new technologies for furniture recycling and transportation; and for consumers, the improvement of their concepts of consuming and the environmental protection. In sum, it aims to provide both suggestions for the amelioration of the measures and methods, and support for the understanding of the change, of used-furniture recycling in China.

Study on the Process Optimization of Peanut Coat Pigment Staining of Poplar Wood

“…The crystallization zone and setting zone area are not easy to measure, so the Segal method, which is usually used in this experiment, is selected. Record the diffraction maximum peak in the area of 2θ = 22 • and the peak of the valley around 2θ = 18 • on the diffraction curve and calculate its crystallization index according to Equation (2).…”

“…Under the prevailing global trend of environmental degradation, wood has garnered significant attention as a renewable and eco-friendly biological substrate [1][2][3]. Due to its rich resources, wood is widely used in industry, furniture, energy, construction, and other fields [4,5].…”

Research on the Recyclable Design of Wooden Furniture Based on the Recyclability Evaluation

“…In 2018, at the request of the government, Beijing piloted the whole process of waste furniture delivery, recycling, transportation and processing in Haidian District, and granted subsidies to enterprises to use the recycled waste wood and sponge as fuel for power generation. In July 2021, Shenzhen drafted the local standard "Specifications for Recycling and Comprehensive Utilization of Waste Furniture," which stipulates the definition, collection, temporary storage, transportation and comprehensive utilization requirements of waste furniture, and improves the recovery rate of domestic waste in Shenzhen (Xiong et al, 2022). Mao et al (2015) divided the recycling methods of old wooden furniture into five aspects, namely reuse, recycling, regeneration, energy utilization and special utilization (as shown in Figure 1 ).…”

“…The global consumption of roundwood has therefore steadily increased from 1.6 billion m 3 at 1992 to 2.2 billion m 3 at 2018, and is estimated to hit 2.4 at 2030 billion m 3 (Peter et al, 2021). China took the largest share of the global consumption amounting to 12% in 2018 (Xiong et al, 2022). Despite as the third largest producer, the domestic supply of China still failed to meet its consumption, nearly 25% of which was imported from other countries (Peter et al, 2021).…”

“…Landfill is currently the most widely used method. The two biggest contributors (i.e., China and US) respectively landfilled 69% and 80% of their total waste wood generated in 2015 (U.S. Environmental Protection Agency, 2022a, b, Xiong et al, 2022). However, direct landfilling not only occupies large amounts of land, but also damage to the environment due to the leaching of hazardous elements (e.g., heavy metals and arsenate poisoning) from the chromated copper arsenate (CCA), Penta and Creosote used as the main preservatives toh delay or prevent the wood product from being decayed (Lykidis and Grigoriou, 2008).…”
