“…The strengths and weaknesses, threats, and opportunities associated with the use of natural conditions and resources are evaluated. The system of factors and guys also affects the processes of ensuring environmentally friendly development [24][25]. Using a strategy, a long-term plan is developed to ensure the purpose of implementing the purpose, tasks, and achievement of goals, with the help of planning, priorities, and directions of strategy execution are determined, as well as tactical and operational actions, to achieve the definite goal.…”

The purpose of the article is to build a multi-vector structure of integrated governing of environmentally safe nature resources use according to the principles of a circular economy approach. Based on the the method of mode indicators and the method of fuzzy logic, the index of environmental safety of nature management has been determined. The interpretation of the essence of integrated administration of environmentally safe nature management is given. The organizational and economic mechanism and its implementation has been displayed. The mechanism of integral management as a set of appropriate measures is considered. A multi-vectoral structure is built, which provides for the formation of a system of mechanisms with adequate levers and tools. The providing, adaptive, functional, effective-target subsystem is characterized. The indicators of environmental, economic and social efficiency are determined, which are targeted guidelines when implementing integrated management. The requirements of a systematic approach for a comprehensive implementation of integrated management of natural resource potential are taken into account.

“…Contrary to [84] and in line with the findings of [24], there is a large and long-standing field of research in AWB-based SCMs for use in concrete production. In this same category, 24% of the studies in the period 2004 to 2021 used AWBs as a total and/or partial substitute material for conventional fine and/or coarse aggregates in concrete [21,28,29,36,66,67,83,[89][90][91][92]. A smaller percentage (3%), between 2019 and 2021, analysed the potential of AWBs as additives and/or aggregates for soil stabilisation and/or improvement of geotechnical properties [69,70,93].…”

Management of agricultural waste biomass as raw material for the construction sector: an analysis of sustainable and circular alternatives

et al. 2022

Background The agricultural and construction sectors demand enormous amounts of natural resources and generate environmental impacts that negatively affect ecosystems. One of the main problems is the generation and inadequate management of waste. For this reason, under the approaches of the new sustainable and circular models, waste valorization has been prioritised as a strategy for advancing towards the sustainability of production systems. This research aims to carry out a general analysis of Agricultural Waste Biomass (AWB) in the production of bio-based products for the construction sector. Bibliometric techniques were applied for the general analysis of the scientific production obtained from Scopus. A systematic review identified the main research approaches. In addition, European projects were reviewed to assess the practical application. This study is novel and provides relevant contributions to new trends in the valorisation of AWB in the building sector and the sustainability benefits. For policymakers, it is a source of information on the contribution of new policies to scientific advances and the aspects that need to be strengthened to improve sustainable and circular practices in both sectors. Results The results show that 74% of the research has been published within the last 5 years. Regarding the main types of AWBs, rice husk ash and sugar cane bagasse ash are the most commonly used in manufacturing a wide variety of bio-based building products. Cement, concrete and bricks are the main bio-based products obtained from AWB. However, a new approach to utilisation was identified in road construction. Conclusions The findings indicate that the AWB is an important resource with great potential for the construction sector. Similarly, that policies on sustainable and circular development have driven scientific progress on new alternatives for the valorisation of AWB to improve sustainability in the construction sector. Although the practical application has also been driven through European projects, development at this level is still low. Therefore, it is necessary to strengthen partnerships between these two sectors and improve government strategies on sustainability and circularity to overcome existing constraints.

“…Making high-performance concrete (resistance or durability) has opened a new stage in the use of concrete. Different types of additives, natural products or industrial residues, known under the name of pozzolanic materials, such as: volcanic ash (tuff), thermal power plant ash, slag, ultrafine silica, a residue of silicone and ferrosilicon production; limestone filler, resulting from the grinding of the limestone used in the preparation of the clinker; ash from rice husk or other agricultural plants (Helepciuc, 2017;Helepciuc et al, 2017;Grădinaru et al, 2017;Helepciuc et al, 2018;Grădinaru et al, 2019). Pozzolanic materials does not have binder properties independently, but their potential is developed by combining them with Portland cement.…”

This research aimed to analyze the effects of using tuff and limestone as supplementary pozzolanic materials on the permeability of a classic C12/15 concrete composition. There were designed two types of concrete compositions with different degrees of permeability, namely P8 10 and P12 10 as reference concrete compositions and eight experimental concrete compositions with tuff in 6% and 10% of the cement quantity and with limestone in the same proportions. According to results, the tuff and limestone led to the decrease of concrete permeability, the best values being registered in the case of using 10% tuff in the concrete composition with P8 10 class of permeability.
