“…Mainly because these bio-based products meet the properties and performance requirements for building materials. In addition, they are similar to commercial products and conform to regulatory specifications [5, 18, To improve the properties and/or guarantee the performance of most of the bio-based products in Table 1, studies suggest substitution percentages between 5 and 15% by weight of AWBs [6,16,18,19,21,25,33,50,51,53,66,69,77,90,100,103,115]. These findings align with a study that identified similar percentages, between 5 and 10% AWB for fired clay bricks [100].…”

“…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].…”

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.

“…The technical feasibility of this process is investigated based on experimental data and the implementation of practical grain sizes where possible (Fiber and Fine). Many recycled materials were used in concrete to substitute aggregates or cement such as construction, electronic, and agricultural wastes [9][10][11][12][13][14]. Furthermore, the recovered PVC wastes have been studied in numerous investigations to substitute aggregates for developing sustainable concretes [4,[15][16][17].…”

The purpose of this study is to investigate the possibility of using the polyvinyl chloride (PVC) wastes as a concrete manufacturing material without pre-treatment. The purpose is also to contribute for restricting environmental pollution and exploitation of natural resources, through the stabilization and the solidification of PVC wastes in concrete. The aim of this experimental study is to evaluate experimentally the fresh and cured properties of PVC concrete based in comparison with ordinary concrete (OC). This study consists in collecting PVC waste, especially the used PVC pipes rejected in nature, and incorporate it into concrete by substitution of sand with different volume ratios (5%, 10% and 15%). In this study, two different shapes (Fiber and Fine) of PVC were considered. According to the test results, the addition of PVC waste in concrete as a partial replacement for natural sand conducts to decrease the workability of fresh concrete. It was noticed that, the concrete with PVC fiber shows a lower workability comparatively with fine PVC concrete. It was also observed that the PVC fiber improves the concrete compressive strength. It increases with increasing the replacement ratio of PVC waste. However, the increase in the ratio of fine PVC leads to a decrease in compressive strength. The better mechanical performance factor (MPF) was obtained for concrete mixes with high PVC fiber and moderate PVC fine ratios. The collected outcomes would contribute to helpful information for recycling PVC waste in concrete mixes.
