“…Another study highlights many uses of rice-straw cement bricks for load-bearing walls [106]. Rice straw can also be used to lower the price of cement bricks with sufficient thermal insulation, appropriate mechanical qualities, and fire resistance [112][113][114][115]. Furthermore, rice straw-based composites with adhesives generated from starch can be used as ceiling panels and bulletin boards [109].…”

The quantity of organic waste generated by agricultural sectors is continually increasing due to population growth and rising food demand. Rice is the primary consumable food in Asia. However, many stakeholders follow a linear economic model such as the “take–make–waste” concept. This linear model leads to a substantial environmental burden and the destruction of valuable resources without gaining their actual value. Because these by-products can be converted into energy generating and storage materials, and into bio-based products by cascading transformation processes within the circular economy concept, waste should be considered a central material. This review examines the composition of rice straw, bran, and husks, and the procedures involved in manufacturing value-added goods, from these wastes. Moreover, starting with an extensive literature analysis on the rice value chains, this work systematizes and displays a variety of strategies for using these by-products. The future development of agricultural waste management is desirable to capitalize on the multi-functional product by circulating all the by-products in the economy. According to the analysis of relevant research, rice straw has considerable potential as a renewable energy source. However, there is a significant research gap in using rice bran as an energy storage material. Additionally, modified rice husk has increased its promise as an adsorbent in the bio-based water treatment industry. Furthermore, the case study of Sri Lanka revealed that developing countries have a huge potential to value these by-products in various sectors of the economy. Finally, this paper provides suggestions for researchers and policymakers to improve the current agriculture waste management system with the best option and integrated approach for economic sustainability and eco- and environmental solution, considering some case studies to develop sustainable waste management processes.

“…Although rice straw and mineral wool can be used individually as thermal insulators [33][34][35][36], their combined use for mortars are not reported yet. This way, this work aimed to evaluate the use of mineral wool fiber (MWF) and rice straw fiber (RSF) to reduce thermal conductivity in Portland cement mortar (PCM).…”

“…Few studies applied several LCIA methods to comprehend potential variations of methods (n = 5), e.g., [70], who used two different GWP methods to increase the robustness of the results using GWPbio [71] and the IPCC GWP100. Other examples of this are [72], who applied ReCiPe and Impact 2002 + , [73], who applied three methods (CML, ILCD and ReCiPe) to reduce the level of bias, and [74], who used EF3.0 but supplemented the GWP with IPCC results. Others applied several LCIA methods, including indicators complementary from different LCIA methods (n = 13), e.g., [75], applying IPCC and USEtox, [76] applying IPCC, AWARE, CED, and the Product Material Footprint, and [64] applying IPCC, CED, and Regarding the applied LCIA methodology (see Figure 13), most studies applied CML developed methods (n = 22) in some variation, referencing either other studies applying the method or following the EN15804 + A1:2013/EN15978 approach (n = 6), i.e., [35,46,54,63,68,69].…”

“…Most studies did not explicitly define what approach was applied, considering the allocation of the system boundaries, i.e., how they handled secondary functions and co-products in the system boundary. However, some studies did explicitly state application of the cut-off approach, also sometimes referred to as the 100:0 allocation, e.g., [43,44,69,81,82], and a few reported explicitly applying system expansion, e.g., [61,74]. Some studies could (only) be presumed to use the cut-off approach as prescribed by EN15804 and EN15978, even though some studies referenced the European norms but explicitly stated that they had applied another allocation approach, e.g., [38,56].…”

Life Cycle Assessments of Circular Economy in the Built Environment—A Scoping Review

2022

View full text Add to dashboard Cite

The Circular Economy (CE) is gaining traction throughout all industries and nations globally. However, despite several attempts, no one-off solutions for assessing the benefits and pitfalls of CE have been established, and neither have any measures with which to determine decisions. In line with this general observation, the Built Environment (BE) is no different. A tendency is observed in which, for the assessment of the environmental impacts of CE, a Life Cycle Assessment (LCA) has been deemed suitable. This paper presents a scoping review, using the PRISMA statement extension for scoping reviews, documenting how LCA has been applied for assessment of CE in the BE. The review covers a broad scope of literature, scoping the landscape, and delimits it into publications where CE strategy has been defined explicitly and described as a CE investigation. Among the LCAs applied, the dominant system boundary choice is the attributional approach. The authors open the discussion on whether this is actually suitable for answering the questions posed in the CE paradigm. From the review, and the discussion, the conclusion suggests that there is no dominant procedure in applying LCA of CE in the BE, even despite commonly developed LCA standards for the BE. Few studies also present the consideration to reconsider the applied LCA, as CE puts new questions (and thereby a potentially greater system boundary, as CE may imply greater societal consequences) that do not necessarily fit into the linear LCA framework currently applied in the BE.
