“…From 2017 to 2022, the proportion of areas not reaching optimal comprehensive efficiency ranged from 70% to 90%, those not reaching optimal PTE ranged from 23% to 53%, and those not reaching optimal SE ranged from 77% to 90%. This indicates that from 2017 to 2022, the PTE of the manufacturing industry in the CPUA was stable and relatively good, with the overall low comprehensive efficiency mainly due to poor SE [22]. After decomposing the comprehensive efficiency, from the perspective of PTE, Zhengzhou, Zhoukou, Changzhi, Jincheng, Heze, Bozhou, and Fuyang cities had effective PTE for six consecutive years.…”

To investigate the high-quality and efficient development of the manufacturing industry in the Central Plains Urban Agglomeration (CPUA), this paper uses the three-stage Data Envelopment Analysis (DEA) and Malmquist index model to evaluate and analyze the manufacturing development efficiency of 30 prefecture-level cities in five provinces of China in the CPUA from 2017 to 2022. First, the DEA model is applied to evaluate the comprehensive efficiency of the manufacturing industry in 30 regions of the CPUA; second, the Stochastic Frontier Analysis (SFA) regression model is used in conjunction with the technical efficiency and scale efficiency of the manufacturing industry to deeply explore and adjust the causes of the current situation in various regions; finally, after re-analyzing the efficiency with the corrected input-output data, the Malmquist index model is used to analyze the total factor productivity index and its decomposed efficiency of the manufacturing industry in the CPUA from 2017 to 2022. The study shows that the pure technical efficiency (PTE) of the 30 prefecture-level cities in the CPUA from 2017 to 2022 is stable and relatively good, and the main reason for the overall low comprehensive efficiency is the poor scale efficiency; after excluding the interference of environmental factors, the average comprehensive efficiency of each city is lower than before the adjustment, with environmental factors and random errors having a significant impact on the manufacturing industry, especially in Bengbu City; the main factor in the decline of the total factor productivity of the manufacturing industry in the CPUA is the hindrance of technological progress; the spatial distribution of the comprehensive efficiency of the manufacturing industry in the CPUA generally shows a pattern of "higher efficiency in the middle, lower efficiency at the edges", and there is a situation of regional development imbalance in the high-quality development level of the manufacturing industry in the 30 regions.

“…The construction industry generates approximately a third of the world's waste [2], including concrete, brick, and wood, which can be repurposed to produce new construction materials [3]. The utilisation of manufacturing waste in the production of construction materials can yield several benefits, including decreased reliance on virgin raw materials, reduced greenhouse gas emissions from waste disposal, and mitigation of the construction industry's environmental impact [4], [5].…”

Over the last decade, research has increasingly focused on reducing the use of natural resources and improving waste management in the construction industry. Various possibilities exist for reducing waste in this sector, ranging from using waste as filler materials to developing new binders and building materials. This study focuses on the development of bio-based building materials using waste from the manufacturing of wood-wool cement boards. The binder and filler materials were obtained from the manufacturing waste and used in this research. The developed materials were tested for their visual appearance, macrostructure, material density, thermal conductivity coefficient and compressive strength. The results showed promising data for the self-bearing bio-based building materials, which had similar thermal properties to other bio-based materials and could be used as thermal insulation materials with a thermal conductivity coefficient of 0.0827–0.1172 W/(mK). The material density of the developed bio-based composites was found to be 430–617 kg/m3. By incorporating manufacturing waste into the production process of bio-based building materials, it becomes evident that overall waste from manufacturing plants can be significantly reduced, and the sustainability aspect of wood-cement board manufacturers can be enhanced.
