“…The quantitative analysis of the transmission spectra was performed in accordance with the standard procedure. 78 The relative optical density, dD , was used to estimate the absorption bands in comparison with the internal standard peak at 1160 cm −1 that characterizes the skeletal pyranose ring vibrations. The spectra were baseline corrected for further analysis.…”

We propose the final softening finishing of textile products based on a complex of modifying effects on a highly ordered cellulose backbone of the secondary cell wall G-layer or on a mesh corset of microfibrillar cellulose in the primary cell wall. We suggest using polypeptide molecule sizes and the strength of polypeptide molecule adsorption binding on a model solid-phase substrate as parameters of the structurally regulated action of cellulase preparations. The article presents an analysis of 11 cellulase preparations as groups of weakly, tightly and medium adsorption enzymes, and also groups of volumetric, peripheral or combined activity manifested in the fiber structure. We show the regularities of enzyme property influence on the fiber pore structure development, changes in the parameters of the fabric bending stiffness and breaking load and technological shrinkage for two modification modes: liquid treatment with flax fiber swelling or low-modulus application solution. For the liquid method of treatment (with a bath module of at least 10) it is recommended to apply highly adsorbable cellulases ( A > 50%), in which the content of molecules with a globule size less than 30 nm does not exceed 15%. For the low-modulus method of treatment it is recommended to use enzymes with the adsorption capacity of at least 40% and a low content of small-sized fractions (no more than 25%). The recommended treatment variants ensure a three to four-fold bending stiffness decrease at the mechanical strength loss of not more than 15% and shrinkage of linen fabrics not more than 0.5%.

“…There is no doubt that legitimacy, and institutional theories played a significant role during the evolution of SDGs benchmarking (D'Adamo, 2019 ). The crossing of functional integration is vital nowadays for the correct declaration of innovative processes, harmonising engineering and economic ventures (Koksharov et al, 2019 ). According to Boons et al ( 2013 ), radical creativity and innovative market models have to develop the CE paradigm.…”

A transition towards a circular economy is a challenge. It is vital to know that circularity and sustainability are two different segments. So, circular economy can only be achieved in the long-term perspective. This study investigates accounting and accountability for circular economy and waste. Considering these principles and based on a critical review of the literature, economic gains from the transition toward a circular economy are measurable; the problems for corporations and governments are diverse; the way to handle the stakeholders who are losing control in the circular economy is considerable. Diffusion of innovation theory is used to conduct this study. It is essential that an organisational design built should help implement the circular model. Targeted questions responded by adopting a systematic literature review approach by applying PRISMA protocol. This study examines 78 publications in English between 2012 and 2021, which present a map of the circular economy-related knowledge published in web of science and Scopus. Besides, this study includes 03 European Commission reports, 01 Ellen Macarthur Foundation report, 01 Council for the Environment and Infrastructure report, 01 report from SUN IZA, 01 UN Global Compact and 01 the Brundtland Commission report. The results highlight how circular economy, waste management, sustainability, accountability, and management accounting practices help to develop an ecosystem and achieve sustainable development goals of the United Nations 2030 Agenda. Theoretical and practical implications are discussed.

“…The authors of the following scientific works [28], [29], [30] proved that in the conditions of the Vibro-liquefied layer, the total surface of the bulk mass of the material increases, as a result of which there is an intensive removal of moisture and an increase in the drying rate. The vibration of actuators, as well as blowing coolant bulk materials with low friction between particles and a slight tendency to aggregation [31], [32], [33], allow you to significantly reduce the speed of the drying agent, which reduces energy consumption for the process. When processing the investigated pectin-containing products (Figure 9) at the 1st stage, vibration compaction is carried out to remove free moisture, which occurs due to the acceleration of the force field:…”

The process of intensifying dehydration of pectin-containing raw materials by using centrifugation with simultaneous application of low-frequency oscillations to the working container creates an electroosmotic effect in unilateral diffusion to improve the filtration process. It is established that to reduce the technological resistance in the presented methods; it is necessary to create a fluidized bed of products due to the oscillating motion of the working capacity. An experimental vibration unit has been developed to determine the rational parameters of the vibrocentric moisture removal process using the electroosmotic effect. It is proved that the complex of the designed equipment provides consecutive carrying out of three-stage vibration filtration-convective drying of high-moisture production by an alternation of action of a stream of the heat carrier, an electromagnetic field, low-frequency fluctuations. According to the research results, the dependences of the kinetics of the moisture diffusion process on the electric field strength are obtained; frequency of electric current and duty cycle of pulses, which allowed to optimize the process parameters according to the criteria of minimizing energy consumption. It was found that the processing time to achieve the desired humidity with the application of vibration, filtration, and electroosmotic effect was twice less than for filtration drying in a fixed bed. In combination with the noted physical and mechanical factors, the proposed technology improves the technical and economic parameters of the studied process.
