“…Circular economic systems were considered to ensure national economic efficiency by cycling, slowing down and narrowing resource and consumer flows while maintaining the initial level of the final product. The transformation of flows in a circular economy is achieved through the formation of production-consumer circular economic systems (CES), which shifts the minimum object unit toward the meso level (Kvasha et al 2021). In this case, the circular mechanism includes such tools as the cluster approach (Kudryashov et al 2023), the principles of industrial symbiosis (Mironova et al 2022), and biorefining models (Akim 2017).…”

“…The concept of a circular economy arose in the context of the need to increase resource efficiency, due to the limitations of many resources, especially natural, material resources. Researchers agree that in order to ensure sustainable development, the linear economic approach that dominated the industrial period needs to be transformed into a cyclical model that provides a focus on the circular economy (Kvasha et al 2021;Ghosh 2020;Geng et al 2019;Bobylev 2021;Lacy and Rutqvist 2016). A significant number of scientific works are devoted to the study of the entire set of issues of the circular economy.…”

“…In 2022, the northwest of Russia accounted for more than half of the volume of pulp and paper production (Order of the Government of the Russian Federation Dated 2 November 2021 N 312-r). Under these conditions, a significant share of the industrial problems of the northwest region, largely related to the scale of industrial pollution, traditionally consists of waste from pulp and paper mills (many of which are toxic) (Kvasha et al 2021). These issues certainly need to be addressed.…”

To ensure development sustainability, the linear economic approach is being transformed into a cyclical model. For the pulp and paper industry (PPI), which occupies a significant place in the Russian economy, the shift of circular principles to the field of bioeconomics is becoming more important. This requires the development of basic biotechnological approaches implemented in closed cycles (biorefining). The aim of this study was to develop the biotechnological foundations of the circular economic system of the pulp and paper industry. To achieve the goal, the factors for the implementation of the circular mechanism in the pulp and paper industry were established. The composition of pulp and paper waste was systematized, taking into account the places of their occurrence; the directions and forms of the biorefining of pulp and paper secondary renewable resources were determined; and the principal possibility of obtaining bioethanol, based on the whole complex of sugars from cellulose production wastes, is shown. A wide range of general scientific methods was involved (analysis, synthesis, classification, modeling, etc.). Statistical methods were used to process experimental results in the field of pulp and paper waste bioconversion. The biotechnologies involved included methods of destruction, detoxification, and conversion of useful resources into secondary raw materials and final products. From the standpoint of the environmental approach, there are serious efficiency imbalances in the pulp and paper industry, which justify the implementation of circular mechanisms for organizing economic systems. The overall efficiency is ensured by the use of renewable resources and obtaining environmental effects. Algorithms and parameters of green biotechnological regulations for pulp and paper industry waste recycling provide the possibility of microbiological production of a complex of products: biocomposites, bioplastics, medical products, fertilizers, feed additives, vitamin supplements, and bioenergy resources. A strategy for the efficient biochemical processing of pulp and paper waste into green ethanol was determined. The possibility of increasing the efficiency of alcoholic fermentation using various biocatalysts was experimentally confirmed. The technological features of this method, associated with the need for microaerobic fermentation modes, were determined.

“…, Quite a lot of scientific works have already been devoted to the study of the circular model of industry [4,8,9]. Green growth theory argues that innovative technologies, models and mechanisms that completely decouple GDP growth from resource use and carbon emissions [10] should provide the compatibility of economic growth with the ecology of the planet.…”

“…Taking into account the emerging externalities, the costs of conditionally free natural resources and ecosystem services, there is an imbalance in achieving the full efficiency of this type of economic activity. The solution to this problem is provided by the implementation of a sustainable circular mechanism focused on models of closed economic cycles [4].…”

The prospects for obtaining bioethanol based on secondary bioresources of the pulp and paper industry are discussed in order to close economic cycles. The transformation of sugars of acidic hydrolyzate of deciduous wood into bioethanol by batch culture of a selected strain of the yeast Saccharomyces cerevisiae with a combination of various xylose-assimilating yeasts was studied. The ethanol yield from hexose`s part was 46% from fermented sugars, its concentration reached to 9,0±0,6 g l-1. The use of pentose sugars under microaerobic conditions (concentration of dissolved oxygen 0.5-3.0%) gave the efficiency of ethanol production up to 26.7 - 35.5% from fermented sugars. The ethanol concentration in terms of the pentose`s fraction was 3.9-4.5 g l-1 (the yeast Pachysolen tannophilus); 5.2 g l-1 (the yeast Candida tropicalis); 5.6 g l-1 (the yeast Candida shehatae). The total amount of ethanol obtained from both hexose and pentose parts after distillation was 4.2-4.6 g (5.2-5.7 ml) with alcohol by volume 96%.
