Metallurgical Technology: A Preliminary Exploration of Statistical Issues Related to the Recovery and Recycling of Recyclable Resources in a Circular Economy 1
Thread Content
Developing a circular economy is an important measure to implement the scientific outlook on development and achieve sustainable economic and social development. Vigorously promoting the development of the recycling and circular utilization industry for renewable resources is an effective way to develop a circular economy and build a resource-conserving society. How to accurately measure the recovery and recycling of renewable resources in a circular economy is a matter of great concern for current macro managers and statisticians. This paper aims to conduct a preliminary exploration of the statistical issues related to the recovery and recycling of renewable resources in the circular economy. I. Basic Concepts There are various understandings, perspectives, and definitions regarding circular economy, recycled resources, as well as the recycling and reuse of such resources. In order to study the statistical aspects related to the recycling and reuse of recycled resources within the context of the circular economy, it is necessary for the author to clarify the meaning of several basic concepts discussed in this article. A circular economy is a new economic development model based on the continuous recycling of materials. The core principles of a circular economy are Reduce, Reuse, and Recycle. These principles aim to ensure that resources are used as efficiently as possible with minimal input, while maximizing their reuse; they also seek to minimize pollutant emissions. By aligning economic activities with the natural cycles of ecosystems, it is possible to achieve ecological sustainability in human activities as well as increased economic efficiency. The key to establishing a circular economy operation model is to set up a system for the recycling of renewable resources, thereby creating within the socio-economic-ecological system three functional systems of production, consumption, and recycling that influence and promote each other, providing an organizational foundation and logistical pathways for the development of a circular economy. Recyclable resources are various wastes generated in the processes of social production and daily consumption that have lost all or part of their original utility; through recycling and processing, they can regain their usability. It mainly includes scrap metals, obsolete electronic products, used mechanical and electrical equipment and their components, waste papermaking raw materials (such as waste paper and waste cotton), waste light chemical industry raw materials (such as rubber, plastics, pesticide packaging, animal bones and hair, etc.), and waste glass. The recycling and reuse of renewable resources refers to the process of collecting various types of waste products that are generated during social production and consumption, still possess some value, can be recycled, and are usable directly or indirectly; these products are then processed to restore their value so that they can be reused. II. Current Status of Statistics on the Recycling and Reuse of Renewable Resources (I) Overview of the Main Statistical Channels In China, the main statistical channels related to the recycling and reuse of renewable resources include: the General Supply and Marketing Cooperative Federation, the China Materials Recycling Association, the China Renewable Resources Recycling and Utilization Association, the China Iron and Steel Industry Association, the Non-ferrous Metals Industry Association’s Recycled Metal Branch, the China Rubber Industry Association, the Plastic Recycling Committee of the China Plastics Association, and the China Paper Association, among others. The statistical data for various channels are as follows: The statistics from the Supply and Marketing Cooperative Federation system include figures related to recycled resources, as well as key economic indicators for enterprises that process waste materials. The main indicators for recycled resources include purchases from producers, sales volume, and inventory levels, while the key economic indicators for enterprises processing waste materials include the number of such enterprises, total output value, and revenue from product sales. The China Materials Recycling Association maintains statistics on the recycling of waste materials, with the main subjects of these statistics being over 600 member organizations, including professional companies engaged in materials recycling and industrial and mining enterprises that operate legally in this field. The main indicators include the amount recovered, sales volume, and beginning (ending) inventory. The main types of waste include scrap steel, scrap non-ferrous metals, scrap plastics, and scrap household appliances. The members of the China Recycling Association include more than 10,000 enterprises engaged in the recycling of renewable resources, covering various types such as waste paper, waste plastics, and waste metals. A basic management network system for the association’s recycling operations does exist, but at present there is no unified set of statistical reports; most of the key statistical data are obtained through targeted surveys and empirical estimates. The scrap steel utilization rate currently used by the China Iron and Steel Association refers to the proportion of scrap steel consumed in a year relative to steel production. The amount of scrap steel includes the scrap steel produced by the enterprise itself, as well as the scrap steel purchased from the market and imported. The data mainly comes from the statistical reports of over 60 key enterprises. The Recycled Metals Branch of the China Non-ferrous Metals Industry Association currently uses two concepts: social recycling rate and processing utilization rate. The social recycling rate refers to the proportion of recycled non-ferrous metals to the total amount of such metals in society, while the processing utilization rate represents the proportion of non-ferrous metals that can actually be utilized in the process of their recycling. The key data are calculated using information from key enterprises and relevant materials. The China Rubber Industry Association currently has a set of statistical reports on enterprise economics and product output, with key indicators including the production volumes of products such as recycled rubber and rubber powder. Recycled rubber and rubber powder are products manufactured from used tires, and thus they reflect to some extent the level of utilization of such tires. The Plastic Recycling Committee of the China Plastics Association, by taking into account the development trends of various plastic sub-industries and using data from the previous year as a basis, makes appropriate adjustments to the plastic waste ratio. By analyzing the five major general-purpose resins as a foundation, it estimates the amount of plastic waste for the current year; from this, it is possible to determine the amount of recycled plastic within the total domestic consumption of plastics. The waste paper recycling rate used by the China Paper Association refers to the proportion of recycled waste paper in total paper consumption. The amount of waste paper recycled is obtained, first, through sample surveys of the 40–50 large companies under its management ； The second method involves estimation based on data such as the production volume of hundreds of small paper mills (for toilet paper and imported wood pulp) and the recycling rate of waste paper. Paper consumption is estimated based on paper sales volume and a certain ratio coefficient.
(II) Main problems existing: 1. The statistical scope is incomplete, and the quality of statistics is not guaranteed. Currently, the statistics compiled by industry associations only include member companies and do not cover various types of enterprises engaged in the recycling and utilization of renewable resources across society. The data used by the association mainly comes from targeted surveys or estimates based on relevant information. 2. The statistical systems are not unified and lack standardization. The existing relevant statistics are scattered across various industry associations, which generally conduct statistics and calculations based on their own management needs; as a result, there are differences in terms of statistical classification standards, calculation methods, and accounting principles. 3. Statistical capacity building is lagging behind. At present, the statistics on the recycling and reuse of renewable resources are primarily collected by industry associations with management responsibilities; **there is no coordinating authority or dedicated staff responsible for these statistical tasks. III. Establishment of a basic framework of statistical indicators for the recycling and reuse of renewable resources
To comprehensively reflect the process of recycling and reusing renewable resources, the basic statistical indicators should consist of both macro-level evaluation indicators and micro-level statistical indicators. Taking into account the diversity and comparability of recycling and reuse activities, the indicator framework initially focuses on quantitative indicators for materials such as scrap steel, non-ferrous metal waste, rubber waste, paper waste, and plastic waste. Macro evaluation indicators mainly reflect the status of **recycling and reuse of renewable resources, while micro statistical indicators reflect the basic aspects such as production, consumption, imports, recycling, and utilization of enterprises engaged in the recycling and use of renewable resources. Framework of basic statistical indicators for the recycling and reuse of renewable resources: Renewable resource recovery rate: refers to the ratio of the amount of renewable resources recovered during the reporting period to the amount generated. Calculation formula: Recycling rate: refers to the ratio of the amount of recycled resources to the amount generated. Calculation formula: From a statistical and operational perspective, the generation of recycled resources involves a wide range of industries and numerous entities, making statistical surveys quite challenging. Considering the entire process of a product from production to sales, use, disposal, and reuse, there is a strong positive correlation between the amount of recycled resources generated and the amounts produced and sold. In the absence of statistics on the amount of waste generated, from an economic analysis standpoint, it is possible to use indicators such as the production or sales volume of relevant products to calculate the corresponding ratios. IV. Recommendations for Implementing Statistics on the Recycling and Reuse of Renewable Resources **The National Development and Reform Commission, in the \"Guidelines for the Comprehensive Utilization of Resources during the 11th Five-Year Plan Period,\" called for accelerating the legislative process related to the comprehensive utilization of resources, with the aim of gradually establishing a legal framework for such utilization that is centered around the \"Circular Economy Law\" and the \"Regulations on the Comprehensive Utilization of Resources,\" supplemented by specialized regulations governing the recycling of various types of waste. Establish a statistical system for the comprehensive utilization of resources, incorporate information and data related to the comprehensive use of key resources into the national economic statistics system, and provide unified and authoritative data and information for **macro-control as well as for enterprises and institutions to carry out the comprehensive utilization of resources. These measures provide a foundational environment for conducting statistics on the recycling and reuse of renewable resources. To this end, it is necessary to seize the opportunity and implement statistics on the recycling and reuse of renewable resources in our country as soon as possible. The author puts forward the following suggestions: (1) Relying on the mechanisms of a circular economy, establish a coordination mechanism for statistics on the recycling and reuse of renewable resources. Statistics on the recycling and reuse of renewable resources is a complex systematic task that involves multiple departments, industries, and types of resources. Coordination and cooperation from relevant regulatory agencies such as the Development and Reform Commission, the Ministry of Commerce, the Administration for Industry and Commerce, and the Environmental Protection Bureau are needed to establish an effective coordination mechanism. Guided by China’s policies on circular economy, as well as the strategies and development goals for the recycling and reuse of renewable resources, efforts should be made to establish statistical frameworks for these activities in China. It is also necessary to enhance coordination among various departments, make full use of the role of industry associations, and promote the development of statistical systems related to the recycling and reuse of renewable resources. (2) Conduct a nationwide survey of enterprises engaged in the recycling and reuse of renewable resources. As this industry develops, the existing statistical data are insufficient to reflect the progress of circular economy development and the changes within the industry, which hinders accurate assessment of the industry’s situation and informed decision-making. Given the characteristics of China’s enterprises in the field of renewable resource recycling and reuse, such as diversified ownership structures, a wide range of business types, and multi-level operations, it is necessary to conduct a comprehensive survey of national markets for the trading of renewable resources, companies engaged in resource recycling, enterprises that process and utilize these resources, waste management companies, community recycling points, as well as individual traders and private operators involved in recycling activities. This will help to understand the basic aspects of this industry, including its scale, structure, distribution, operations, assets, and workforce. Such information will provide a reliable data basis for formulating industry policies, and it will also serve as a foundation for establishing regular statistical systems and carrying out various statistical surveys in order to optimize the use of statistical resources. (III) Establish a regular statistical system to ensure the completeness and continuity of data. Developing a circular economy is an important strategic approach that China will adhere to in the long term. To this end, **it is necessary to improve statistical indicators based on the existing statistical data from relevant departments, expand the scope of statistics, refine survey methods, and establish a unified and standardized system for regular statistical surveys, with specialized agencies responsible for coordinating its implementation in order to ensure the completeness and continuity of the data. (IV) Conduct specialized surveys to leverage the statistical capabilities of associations. Recycled resources and materials can be classified into categories such as scrap steel, scrap non-ferrous metals, scrap rubber, waste paper, and plastic waste. The production processes and techniques for each of these categories have their own particularities. **Statistical agencies should make full use of professional associations to carry out various specialized statistical surveys, including key surveys, typical case studies, and sampling surveys, that meet the needs of managing the recycling and reuse industry as well as those of the circular economy evaluation system, thereby making better use of the statistical expertise of professional associations. (5) Establishing statistical quality assurance and data dissemination systems. Statistics on the recycling and reuse of renewable resources is a task that involves multiple departments and specialties, requiring coordination among various departments, associations, and enterprises. Only by establishing standardized procedures, quality assurance measures, and data dissemination systems for all stages—from statistical design, data collection, compilation, and estimation to data release—can unified and authoritative data be provided for macro-control as well as for enterprises and institutions to carry out comprehensive resource utilization. Statistics on the recycling and reuse of renewable resources is an important and new field that requires strategic thinking and keeping up with evolving trends. The development of this statistical work should be guided by **macro policies and industrial policies, based on industry regulation, and utilize high-quality statistical information to promote the healthy development of the industry. The author is concerned with the statistical aspects of renewable resource recycling and reuse, and hopes that an objective description through statistics can raise the awareness of producers and consumers regarding resource conservation and environmental protection, thereby promoting and strengthening relevant legislative and regulatory measures. This effort is aimed at contributing to the establishment of a resource-efficient and environment-friendly society, as well as ensuring the economic and social sustainable development of future generations.

Circulation and recyclability are advanced concepts; material recycling involves not only the recovery of physical resources but also energy resources and environmental resources. :lol
A preliminary exploration of statistical issues related to the recycling and reuse of renewable resources in a circular economy is worth studying
