Novel Evaluation Method for Cleaner Production Audit in Industrial Parks: Case of a Park in Central China

With respect to peak carbon and carbon neutrality, China’s economic structure is developing towards low carbonization, circulation, and cleanliness. There is an urgent need to expand the scope of cleaner production audits, improve cleaner production efficiency, and promote cleaner production through regional coordination. The 14th Five-Year National Cleaner Production Implementation Plan proposed selecting 100 parks or industrial clusters to conduct an overall cleaner production audit innovation pilot. To promote the coordinated development of cleaner production areas, this study constructed a set of cleaner production index systems for industrial parks, established an evaluation model based on the binary semantic evaluation method, and selected an industrial park in central China as an audit pilot. The binary group θ1=(2, −0.1084) of the rating results was determined to be a cleaner production park. Based on the evaluation results, the clean production potential of the park was analyzed, and suggestions for clean production were put forward. Sixteen representative enterprises in the park were selected to build twenty-one ecological chains, providing reasonable suggestions for constructing a systematic and circular enterprise symbiosis network.

Bacterial nanocellulose, a sustainable alternative, to implement cleaner production in the design of biosensors to detect heavy metals in surface waters

While high productivity is positive for growth in developing countries, environmental balance and moderation in pollution levels must be taken into consideration. The dumping of highly harmful industrial waste into river beds, streams, groundwater tables and underground freshwater reservoirs is a clear disadvantage when thinking about sustainable processes. Putting the environment first, we wonder how many thousands of liters of vinase and toxic waste run through our watersheds to end up reusing some bagasse to extract vegetal origin cellulose. It is not about demonizing the product, but rather applying cleaner production technologies to obtain it in a sustainable and ecologically friendly way. The main objective of this review is to propose nanocellulose of bacterial origin as an inert support material for biosensors that detect heavy methals on surface waters. This alternative is sustainable, resistant to temperature and high humidity levels, optical transparency, porous nanostructure and possibilities for surface functionalization. This material has advantages over vegetable cellulose, not only functional, but also from the aforementioned environmental perspective. Heavy metals contamination on surface waters is a global problem. The development of reliable, lightweight and portable biosensors is a necessity for in situ detection of the degree of contamination, without the need for cumbersome and often complex sample taking. The performance of a biosensor depends on its ability to immobilize receptors, maintaining their natural activity, against targets in solution, as is the case of our interest. When we propose bacterial nanocellulose as a support it is due to its ability to form covalent bonds and trap by cross-linking. Although due to their high surface area per unit of volume, physical methods are also a possibility that provides versatility of processes that adapt to multiple biosensor formats. Each new discovery of the potential functionalization for bacterial nanocellulose allows us to think of new, more efficient, more environmentally friendly sensors for a multitude of applications. As the contamination of water with heavy metals increases alarmingly due to over-industrialization, it is time to ask ourselves about the cognitive dissonance of using cellulose obtained by traditional means and the aforementioned contamination that they carry to generate sensors to measure the degree of pollution that we generate when producing it.

Cleaner production and total factor productivity of polluting enterprises

The green and high-quality development of China's manufacturing industry requires the implementation of cleaner production practices. This study constructs a cleaner production index for polluting enterprises based on the detailed indicators of industrial cleaner production standards. Using data from the Green Development Database and the Industrial Enterprise Database from 1998 to 2012, this study analyzes the influence, transmission mechanism, and heterogeneity effect of the cleaner production index on the total factor productivity of polluting enterprises. The results show that improving the cleaner production index of polluting enterprises promotes total factor productivity, and this conclusion remains valid after taking several robustness tests. The improvement of the cleaner production index of polluting enterprises brings the demand for skilled labor and equipment capital containing technological progress, and the improvement of productivity comes from the capital-embodied technological progress which is complementary to the skill demand and skill premium. The study also finds that increasing the cleaner production index of polluting enterprises has a greater promoting effect on the total factor productivity of heavily polluting industries, large-scale enterprises, and enterprises in the western region. The improvement of the cleaner production index of polluting enterprises increases total factor productivity of state-owned and private enterprises but has no effect on foreign enterprises. These findings provide empirical evidence and policy implications for promoting high-quality development of the manufacturing industry through cleaner production governance, highlighting the importance of implementing cleaner production practices, introducing advanced production equipment, and skilled workers to achieve economies of scale and increase total factor productivity.

Does Environmental Regulation of Cleaner Production Affect the Position of Enterprises in Global Value Chains? A Quasi-Natural Experiment Based on the Implementation of Cleaner Production

Present-day supply-side structural reform in China places an abundance of emphasis on environmental protection. In this paper, we re-measure the upstreamness of Chinese enterprises in global value chains as described by Ni Hongfu (2022). Subsequently, the impact of environmental regulations on the global value chain position of Chinese firms is studied in depth, using the cleaner production standards promulgated and implemented by the Chinese government in 2003 as a quasi-natural experiment, taking a time-varying difference-in-differences (DID) approach. The data sources employed include the Cleaner Production Standard Implementation Industry Directory, the World Input–Output Database (WIOD), the China Industrial Enterprise Database, and the China Customs Import and Export Database. This research discovered the following: First, adopting cleaner production standards significantly improves Chinese enterprises’ positions in the global value chain—a conclusion that holds up to a number of robustness tests. Second, in terms of firm size, capital intensity, ownership characteristics, and government subsidies, there exists a noticeable heterogeneity in the promotion of the adoption of cleaner production standards for the improvement of Chinese enterprises’ global value chain position. Third, the implementation of cleaner production standards stimulates the upgrading of Chinese enterprises’ global value chain position, primarily through the entry and exit impacts, product-switching effect, and innovation compensation effect. The following proposals for policy can be implemented in light of the findings of this paper: “upstream prevention” strategies in the development of future environmental protection and trade policies should be advocated; nuanced and stratified environmental policies should be meticulously constructed; a mix of policies should be employed to bolster the institutional support for green environmental regulations; the integration of environmental governance into the evaluation framework should be emphasized; the creation of an innovation-oriented environmental governance system should be expedited. In conclusion, the findings of this research provide empirical evidence on the role of environmental regulations in coordinating ecological development and strengthening the position of Chinese enterprises in global value chains, which may assist other developing nations in making the transition to a path of high-quality growth.

THE INFLUENCING FACTORS IN CLEANER PRODUCTION ADOPTION ON THE ALUMINIUM PROCESSING INDUSTRY

Cleaner Production (CP) practices comprised environmental strategy perpetually applied in the production, processes, and services to bolster efficiency, safety, and environmental friendliness. Some factors are to be considered to achieve a cleaner production strategy: stakeholders establishment, surveys, utilization, and impact, as well as how the top management devote their practices towards cleaner production. Combining with the mindset of sustainable stocks and resources, this exercise of cleaner production provides advantages of minimum toxic wastes and residues. In this study, we prioritize this practice to be applied in the aluminum industry, of which cleaner production action has not yet been employed. Small and medium businesses now no longer have enough monetary assets to put money into cleaner production practices because they require high-cost investment. This study aimed to determine the factors that have an impact on the application of cleaner production. The method used is regression analysis. The regression analysis results showed that three variables were tested to be significant and had a Root Mean Square Error (RMSE) value of 3.05 which means good. Three variables that affected the implementation of cleaner production include measurement of fuel usage, efforts to improve production process efficiency, and waste reuse by product. From the calculation results, the coefficient of determination (R2) was 0.550 (the influence was quite strong). The results of this study can be used as a recommendation for the government to increase the implementation cleaner production in Jombang Regency.

From cleaner production to sustainability: multiple case studies in Uruguayan companies

Since the concept of cleaner production (CP) considers not only the environment but also the economic and social dimension, additional scholarly attention is focused on studying the relationship of CP to sustainability. This research aims to present the main elements that contribute to successful CP implementation and sustainability in organisations. Eleven companies, mostly SMEs that adopted CP practices after a training course, were selected from different industrial sectors. The main results showed that the critical success factors most often cited for achieving successful implementation are commitment from top management and government support. Although some companies continue to implement sustainable practices, the majority apply CP only to comply with environmental laws, which results in a limited contribution to sustainability. Additionally, the analysed companies do not have standardised metrics to evaluate their sustainable performance, but CP serves as a guide to support their decisions. More effort is needed to make companies aware of the benefits of CP in other areas of organisations, and to integrate the three domains of sustainability when implementing CP practices.

Finally, energy-intensive manufacturing companies in China are compared and evaluated, and the effectiveness of the proposed strategy is discussed.

Analysis of cleaner production potential and water footprint for small-scale sweet potato flour industry

Sweet potato flour is one of the derivative products of sweet potato, especially for raw materials or additives in the food industry. The processing of sweet potato-based products must also be balanced with existing environmental management. For this reason, there is a need for suitable methods to deal with processes that produce minimised wastes that harm the environment. Cleaner production is an approach that offers various environmental benefits for the sweet potato flour industry. Identification of cleaner production alternatives was carried out by the quick scan method for minimising the presence of waste in the sweet potato flour industry. The feasibility of the cleaner production design was analysed by considering technical, environmental, financial, and economic aspects. Identification of water use was done by calculating the water footprint in the whole production process. The water footprint was calculated by adding up the green, blue, and grey water footprints to obtain the total water usage in the production process. The use of water for planting sweet potato (green water) is estimated to be approx. 1.093 m3/ton of sweet potato flour. With a sweet potato flour yield of 50.8%, the production of sweet potato flour requires a water volume (blue water) of 1.32 m3/ton of sweet potato flour. The following cleaner production alternatives were identified as prospective for waste minimisation in the small-scale industry, including good manufacturing practices, repairing flour machines, drying using a greenhouse, training in the selection of raw materials and training in standard operating procedures (SOPs) for flour production, and utilisation of sweet potato peel as animal feed. With the implementation of cleaner production and more efficient use of water, it is expected that the sweet potato flour industry will become a more sustainable industry.

The Indonesian batik, which is usually produced by small and medium enterprises (SMEs) often consumes a lot of water and causing environmental pollution. Therefore, a study to map the water use for batik production is required. This study examines the Blue Water Footprint (BWF) and Grey Water Footprint (GWF) of block-printed batik making-process coloured by Indigo (Indigofera sp.), Mahogany (Swietenia sp.) and Tingi (Ceriops sp.) dyes produced by a batik SME in Jarum village of Klaten Regency, Indonesia. The average BWF of block-printed batik making-process coloured by natural dyes was lower than the GWF and Indigo consumes more water in dyeing, followed by Tingi and Mahogany. The dyeing process consumes less water for BWF (2.96 L/pc), while the biggest portion of BWF was contributed from the wax removal process (152.81 L/pc). Implementation of cleaner production by managing the grey water, such as the implementation of communal Wastewater Treatment Plant, adopting water conservation strategies and educating the craftsmen are necessary to achieve batik and water resource sustainability.

Construction of cleaner production management system in China: mode innovation of cleaner production.

This study is based on the practice of cleaner production (CP) audits in more than 300 enterprises. After reviewing 1484 CP options, it is found that 82.5% of the options are directly and indirectly related to management. Moreover, there are common problems such as the poor sustainability of CP audit results. This shows that enterprise management plays a significant role in implementing CP options. Based on these, this study proposes a new concept of cleaner production management (CPM) system, and draws lessons from the modern environmental management theory and method to establish the framework of CPM system. This system combines the theory and method of CP with the management system of enterprises and presents the CPM requirements in the current enterprise management system, which mainly includes CPM responsibilities, CP objectives, CPM indexes, CP energy resources management, CP process control, CP product management, CPM inspections, and CP performance evaluation. The characteristic of the proposed system is to construct a modern information-based CPM system. With highly systematic, concise structure, and easy operability, this system not only simplifies and improves the CP work in enterprises and reduces several tedious tasks such as document preparation, but also enhance the enterprise management efficiency and motivate the willingness of employees to participate in CP. Innovated and developed for CP implementation, the system has been implemented and applied in Chinese enterprises, and the implementation and application have obvious effects on improving production level as well as environmental and economic benefits.

Nitriding in non-toxic salts bath: An approach to implement cleaner production in the metallurgic industry

The need for sustainable development has been reflected in the adoption of cleaner production initiatives in the last years. However, the literature indicates that more research is still necessary to engage industries in adopting alternatives to reduce environmental impact. In that regard, we investigated a way to reduce the environmental impact in the metal-mechanical industry, caused by the conventional salt bath nitriding process. This technique commonly uses cyanides and cyanates salts as a nitrogen source for the formation of nitrides coating to improve the metal surface properties, especially to achieve high hardness. Thereby, this paper sets out an approach, as an alternative to obtain a nitride layer, formed by non-toxic salts: potassium nitrate additivated with a new condition of antioxidative salt, potassium chloride, which improves the nitriding efficiency and surface finish of carbon steel 0.2% C. The results indicated the formation of a white layer of 8 μm thickness and a diffusion zone around 200 μm, after 3 h of nitriding. There was an increase in hardness, from 198 HV on the substrate to 702 HV on the nitrided surface. Consequently, one can conclude that the use of non-toxic salts is an efficient alternative to improve the surface properties in low carbon steel with the advantage of applying green engineering approaches, feasible technologically to the decrease in the amount of pollution.
