“…Using the system boundary definitions as met in Environmental Product Declarations, according to EN15804:2012 + A1:2013 [2] (Cradle-to-gate, Cradle-to-gate with options, and Cradle-to-grave w./w.o. module D/potential beyond system boundary), we additionally define a category for 'Other', covering studies assessing EoL [57], or Construction, Use and Deconstruction [58]. The assessed system boundaries predominantly represented cradle-to-gate w. options (n = 42), with the second most being cradle-to-gate (n = 30), regardless of whether the studies were conducted according to 'only' the ISO standards, or following the modularity of the European norms for the construction industry, see Figure 10a.…”

Of the papers using ILCD as an LCIA method, one of them was through EN15804:2013 + A2:2019 [57]).

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

2022

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.

“…In addition to the reliability of statistical support, the need to form a coordinated and complete information support for construction waste management is emphasized in other studies. The issue of forming information support for construction waste management has been solved by creating integrated databases [10], forming a policy of greater awareness of stakeholders about the circular economy and the quality of the economic justification for management decisions [11]. Noting the importance of the quality and completeness of information support, it was desirable to focus on information predictors for each of the participants in the construction waste management system.…”

The object of this study is a system of incentives aimed at activating the processes to manage construction waste formed during hostilities. The problem being solved is to form incentives for the growth of economic interest in construction waste management. The structural and functional readiness of the economy for the management of waste generated as a result of hostilities is investigated. It was revealed that 60 % of the participants in the waste management system are microenterprises with a profitability of 0.2 %. The level of construction waste disposal and the level of its reuse are estimated. Forecasts of the behavior of methods of waste management in the absence of changes in state policy have been made. Based on the use of forecasting methods, a trend of increasing the amount of waste dumped at landfills has been identified. The directions of state influence on the formation of economic incentives for the processing of construction waste have been proposed. A special feature of the study's results is that the inconsistency of existing incentives with the needs of participants in the field of waste management has been investigated. The problem with the activities of small enterprises is the demand for performance, at the formation of which government efforts should be directed. Distinctive features of the results are that they solve the problems of achieving a balance of economic interests of participants in the management of construction waste generated during the war. The area of practical use of the obtained results is the system of state and local management of waste handling activities

Ceramic bricks are among the most used building material throughout human history for their excellent technical properties, abundance of raw materials and easy production. Huge quantity of brick waste is generated from demolition works at the end-of-life stage of buildings. Several scenarios within waste management hierarchy can be considered: a) preparing for reuse of bricks into masonry units for similar purposes; b) mechanical recycling (crushing, screening) to crushed stone for various applications -in backfilling, pavement, drainage works, which are examples of down-cycling or as concrete aggregate and as a component in blended binders which are examples of upcycling; c) disposal at inert waste landfills or used as a separation layer at municipal waste landfills. This study performs a life cycle assessment (LCA) of these three possible routes for ceramic waste and takes into account the relevant processes. The LCA results are calculated for the compulsory environmental indicators according to the methodology of EN 15804 along with the additional indicators assessing toxicity. The outcome of the LCA confirms that the most environmentally beneficial scenario is the reuse of bricks as it requires minimal activities for preparing. Technical feasibility issues and costs impact, associated to the three scenarios are also analysed. The conclusion is that an optimised and sustainable approach of bricks end-of-life shall be applied in order to boost the circularity in construction sector.
