The amount of plastics deposited in the environment is constantly increasing. To improve their circularity, numerous research lines emerge, such as the creation of new construction materials that incorporate polymeric waste. This practice manages to extend the life cycle of the waste, avoids the consumption of limited natural resources and gives the product additional characteristics. The re-use of polyurethane foam waste as a substitute for gypsum in ceiling tiles carries technical improvements such as a decrease in the weight of the material and in its thermal conductivity, maintaining a positive fire reaction performance. The goal of this work is to analyse its economic viability. For this, the financial assessments of the PU-Gypsum product and its standard alternative are compared. The results show that the Life Cycle Cost Analysis (LCCA) of the new precast is 6% cheaper. Despite the fact that the waste processing entails an extra cost, this is widely offset by the increase in the factory’s production capacity due to its shorter drying time. The manufacturing stage represents 3/5 of the total cost for both materials. The PU-Gypsum precast is an ideal market alternative to the traditional gypsum one with improved properties and proficient in an economic level.

“…Moreover, some studies based their calculations on simplistic addition of emissions or other manual calculations (n = 16), and others did not state explicitly how their results were derived (n = 11). 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].

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.

One of the most popular materials used in the plastics industry is polyurethane (PUR). In recent years, these plastics have gained attention due to their ease of processing, their simple, relatively inexpensive manufacturing process, and, above all, their properties, which allow PURs to be used as rigid and flexible foams, flexible solid products, adhesives, and biomedical materials. The primary purpose of this work was to study the chemical and/ or physical modifications of urethane prepolymers, resulting in enhanced mechanical properties and reduced flammability. A crosslinking agent based on triesters of phosphoric acid (PPEG) was synthesized and used as a component to produce PUR and poly(urea-urethane)s (PUUR). Commercially available polyether diols, with average molar masses of 450 and 2000 g•mol −1 , and aromatic diisocyanates were used. In the further course of work, thermal properties, flammability, and selected mechanical parameters of the obtained materials were characterized. The addition of PPEG allowed one to achieve products exhibiting better tensile strength, up to 19-fold improvement in properties from 0.51 to 9.71 MPa, and increased thermal stability of materials. Moreover, the PPEG derivative has the ability to reduce the flammability of materials, which has been proven during tests on the calorimeter, where there is a decrease in the heat release capacity (HRC) and the peak heat release rate (peak HRR) compared to the unmodified PUR reference sample by 44.34 and 46.70%, respectively, for the material with the highest derivative content.
