“…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].…”

“…Therefore, most of the studies in the sample analysed considers physical, chemical, mechanical and other properties of the bio-based products. This was to identify the effects of AWBs and determine compliance with the standards of the regulations governing the quality of building materials [90]. Table 2 summarises the main parameters evaluated for each of the properties.…”

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 concern about protecting water quantity and quality is one of the most severe challenges of the twenty-first century since the demand for water resources grows as the population and its needs grow. Additionally, and as expected, most human activities produce wastewater containing undesirable contaminants. On the other hand, the generation of agricultural waste and its inappropriate disposal causes further problems. Current wastewater treatment methods involve a combination of physical and chemical processes, technologies, and operations to remove pollutants from effluents; adsorption is an excellent example of an effective method for wastewater treatment, and biochar is currently one of the most valuable adsorbents. This review focuses on new research about applying biochar produced from agricultural waste as a low-cost and environmentally friendly method for removing ammonium and phosphates from aqueous solutions.
