Life Cycle Assessment (LCA) is considered an innovative tool to analyze environmental impacts to make decisions aimed at improving the environmental performance of building materials and construction processes throughout different life cycle stages, including design, construction, use, operation, and end-of-life (EOL). Therefore, during the last two decades, interest in applying this tool in the construction field has increased, and the number of articles and studies has risen exponentially. However, there is a lack of consolidated studies that provide insights into the implementation of LCA on construction and demolition waste (C&DW). To fill this research gap, this study presents a literature review analysis to consolidate the most relevant topics and issues in the research field of C&DW materials and how LCA has been implemented during the last two decades. A systematic literature search was performed following the PRISMA method: analysis of selected works is based on bibliometric and content-based approaches. As a result, the study characterized 150 selected works in terms of the evolution of articles per year, geographical distribution, most relevant research centers, and featured sources. In addition, this study highlights research gaps in terms of methodological and design tools to improve LCA analysis, indicators, and connection to new trending concepts, such as circular economy and industry 4.0.

This article presents a redesign methodology based on modularity to minimize resource consumption and reuse components, avoiding the need to replace a whole product with another with higher functional performance. The method employs two decision algorithms to modularize product families that offer the same functionality in different levels (i.e., scalable functions) based on design parameters such as geometry, size, and functional relationships among components. The proposed approach's benefits are demonstrated through a case study of a family of upper limb prostheses. Significant improvements in the manufacturing stage, such as raw material and energy consumption, manufacturing cost, and complexity, were obtained from implementing the method. Other benefits in the use stage were also obtained from modularization, increasing the product family's reuse of components.

Nowadays, construction, maintenance, reparation, rehabilitation, retrofitting, and demolition from infrastructure and buildings generate large amounts of urban waste, which usually are inadequately disposed due to high costs and technical limitations. On the other hand, the increasing demand for natural aggregates for concrete production seriously affects mountains and rivers as they are the source of these nonrenewable goods. Consequently, the recycling of aggregates for concrete is gaining attention worldwide as an alternative to reduce the environmental impacts caused by the extraction of nonrenewable goods and disposal of construction and demolition waste (C&DW). Therefore, this article describes the effect on the mechanical properties of new concrete using recycled aggregates obtained from old paving stones. Results show that replacing 50% by weight of the fine and coarse aggregate fractions in concrete with recycled aggregate does not meaningfully affect its mechanical behavior, making the use of recycled aggregates in new precast paving stones possible. Therefore, the latter can reduce environmental impacts and costs for developing infrastructure and building projects.

Green roof systems represent an opportunity to mitigate the effect of natural soil loss due to the development of urban infrastructure, which significantly affects natural processes such as the hydrological water cycle. This technology also has the potential to reduce the indoor building temperature and increase the durability of waterproof membranes, reduce run-off water and heat island effects, create meeting places, and allow the development of biological species. However, despite the described benefits, the use of this technology is still limited due to the costs and the environmental impact from using non-renewable building materials. Therefore, this article presents the hydraulic and thermal analysis of different semi-intensive green roofs using recycled (rubber and high density polyethylene (HDPE) trays) and reused materials (polyethylene (PET) bottles) in their drainage layers. Then, three roof systems were evaluated and compared to traditional drainage systems made with natural stone aggregates. Results showed that some systems are more useful when the goal is to reduce temperature, while others are more effective for water retention. Additionally, this study presents evidence of the potential of reducing the dead loads and costs of green roofs by using recycled and reused materials in drainage systems.

The Circular Economy comprises several strategies to enhance the sustainability of products. However, most of the research in this area has focused on Recycling, Recovering and final disposal. Strategies for lifespan extension such as Reuse, Repair, Refurbish, Remanufacture and Repurpose lead to higher circularity and value throughout the lifecycle but are less studied. Here we propose a single generic indicator based on durability and environmental footprint for material selection as an early step in the design process towards extending product lifespan. The material durability indicator or MDI integrates into a single calculation chemical and mechanical durability, together with environmental impacts associated with the material. The proposed indicator incorporates parameters such as flammability resistance, resistance to ultraviolet radiation, resistance to water, resistance to organic solvents, mechanical strength, energy consumption, and carbon footprint, among others. A case study based on polymer materials selection demonstrates the usefulness of the MDI indicator, providing a holistic calculation and comparison of selection alternatives, including conventional and multicriteria approaches. The proposed indicator offers a balanced and technical measurement of durability and environmental burdens in the material selection process and can potentially be applied to any engineering material.

Green roof systems, a technology which was used in major ancient buildings, are currently becoming an interesting strategy to reduce the negative impact of traditional urban development caused by ground impermeabilization. Only regarding the environmental impact, the application of these biological coatings on buildings has the potential of acting as a thermal, moisture, noise, and electromagnetic barrier. At the urban scale, they might reduce the heat island effect and sewage system load, improve runoff water and air quality, and reconstruct natural landscapes including wildlife. In spite of these significant benefits, the current design and construction methods are not completely regulated by law because there is a lack of knowledge of their technical performance. Hence, this review of the current state of the art presents a proper green roof classification based on their components and vegetation layer. Similarly, a detailed description from the key factors that control the hydraulic and thermal performance of green roofs is given. Based on these factors, an estimation of the impact of green roof systems on sustainable construction certifications is included (i.e., LEED—Leadership in Energy and Environment Design, BREEAM—Building Research Establishment Environmental Assessment Method, CASBEE—Comprehensive Assessment System for Built Environment Efficiency, BEAM—Building Environmental Assessment Method, ESGB—Evaluation Standard for Green Building). Finally, conclusions and future research challenges for the correct implementation of green roofs are addressed.

Finding sustainable solutions to worldwide problems has become a critical challenge for engineers. The use of natural resources and the generation of materials no degradable should be controlled when sustainable solutions are pursued. As a result, the notion of reusing materials and products for longer periods is gaining momentum in the design for sustainability, and the circular economy is becoming the new paradigm to be implemented for that purpose. In contrast to the traditional linear economy that is focused on making, using and disposing of products, the circular economy is focused on remanufacturing, reusing and recycling products and materials to extend their life. However, the circular economy is not formally introduced in the academia and futures engineers are not getting prepared to incorporate it into the design for sustainability. The aim of this work is to propose a pedagogical approach to introduce the concept of circular economy in engineering design. A case study is presented to compare the design of a product based on the linear economy model (manufacture, use, waste) and the redesign of the product using the circular economy model (remanufacture, reuse, recycle). The comparison will be attained using sustainability performance indicators considered from early design stages. The contrast between the original design based on the linear economy and the re-design using the circular economy allows illustrating the benefits of the circular economy model to enhance the sustainability performance of a product. Additionally, the proposed approach promotes students’ awareness of the impacts of decisions made during the design stage on sustainability including material consumption, energy, emissions, and costs among others. It is expected that the proposed method influences students' engineering design processes regarding sustainability in product design inspired by the feel, think, do. In the long term, it is expected that the technique will be mastered easily by the engineers working on the area of product design who will have sufficient background on the topics of sustainability and circular economy; thus, this practice can be replicated in the professional industrial field. An example is presented to demonstrate the applicability of the proposed approach.

Modularity is one of the most useful tools employed in the product development process. Regarding functionality, the use of modules is common to generate flexible platforms to manufacture products and product families that require functional variations. In the current globalized market, the mass individualization or personalization is the preferred production model that delivers cost-effectiveness and satisfaction at the level of the market of one. In this model, the modularity is employed as a powerful concept applied not only for the manufacture but also for the use and final disposal stages, in which the design of modules provides functionalities and features that satisfy a variety of specifications for different market segments. Despite the existence of approaches in modularity and its usefulness in product development, it is possible to identify a lack of analysis of modular and open architecture to enhance the sustainability performance of products regarding strategies to diminish adverse impacts during their lifecycle. This paper provides an analysis of the influence and potential of Modular Architecture Principles – MAPs in the sustainable design of open architecture products. Additionally, lifecycle considerations are analysed to identify and propose strategies that enforce the sustainability performance of products concerning personalization from early design stages Abbreviations: MAPs: Modular Architecture Principles; FMS: Flexible Manufacturing System; RMS: Reconfigurable Manufacturing System; EOL: End Of Life; LCA: Life Cycle Assessment; QFD: Quality Function Deployment; DFMA: Design For Manufacturing And Assembly

The purpose of this paper is to perform the analysis of literature review regarding the design of open architecture products (OAP) and their potential benefits within the circular economy (CE) model. The analysis involved studying more than 80 research articles during the last two decades in engineering journals. The articles were gathered through a bibliometric analysis using the most relevant keywords concerning product design, sustainability, OAP, and CE. Main trends, challenges and future scopes of research opportunities and development were identified. The study provides a framework to designers and researchers involved in the design of OAP to enhance their sustainability performance for a CE model, which integrates lifecycle considerations (reuse, remanufacturing, repair, and recycle), resource optimization, and emissions reduction. The findings include the need for design methods focused on the design of OAP to guarantee an effective circularity of resources during the whole lifecycle of products and the need of integrating manufacturing processes and material analysis to design products capable of adapting to the CE model.

Cellulose-based aerogels hold the potential to become a cost-effective bio-based solution for thermal insulation in buildings. Low thermal conductivities (−1·K−1) are achieved through a decrease in gaseous phase contribution, exploiting the Knudsen effect. However, several challenges need to be overcome: production energy demand and cost, moisture sensitivity, flammability, and thermal stability. Herein, a description and discussion of current trends and challenges in cellulose aerogel research for thermal insulation are presented, gathered from studies reported within the last five years. The text is divided into three main sections: (i) an overview of thermal performance of cellulose aerogels, (ii) an identification of challenges and possible solutions for cellulose aerogel thermal insulation, and (iii) a brief description of cellulose/silica aerogels.

Currently, design for sustainability is a necessary issue in any product development process. This situation is due to the existing and increasing pressure under industrial activities that follow a linear economy model based on design, manufacture, use and final disposal. As a feasible solution, Circular Economy (CE) model is considered a key strategy to enhance the overall sustainability performance of products, including strategies to improve the useful life of products and close flows of material in a circular path. In the measurement of circularity, existing sustainability indicators are oriented solely to single products and do not consider the product family approach, which involves the use of a common product platform comprised by constructive components or modules able to generate different product variants to satisfy a variety of customer requirements. Consequently, this paper proposes six indicators regarding material flow, reusability, reconfiguration, and functional performance. Such indicators are focused on measuring the circularity of product families respect the circularity of components among their product variants. A case study based on a family of prosthetic fingers is developed to demonstrate the implementation and usefulness of the proposed set of indicators.

The estimation of the sustainability performance of products requires tools to provide systematic approaches to the definition of impacts, indicators and comparative scenarios from early design stages. This paper illustrates the Relative Assessment of Indicators in Sustainability Enhancement (RAISE) methodology that is based on the measure of negative impacts generated during any product life cycle stage. This approach includes a systematic process for the definition and evaluation of indicators to compare the sustainability performance of products considering each indicator individually and using a holistic index of sustainability to entail an overall comparison between products from manufacturing scenarios. The RAISE method is developed with the aim of assessing sustainability performance of product life cycle stages and incorporating this assessment into the decision-making process when comparing different manufacturing scenarios. A guitar capo manufactured in polymeric material is used as case study to demonstrate the use of the method. In this paper, only the manufacturing stage is considered; however, the method can also be employed in other stages of the life cycle.

New trends in product design require the use of modularity as key feature aimed to improve functional performance and the generation of open architecture products. For mechanical systems, one of the challenges during early design stages of these products involves the proper selection of joining methods among their constructive components. A robust joint selection process must consider product requirements, life cycle analysis and eventual procedures for assembly and disassembly. However, the general approach towards a Design-for-Assembly (DFA)/Design-for-Disassembly (DFD) only considers design, manufacturing and in some cases final disposal stage. Additionally, most of the works found in the literature are merely focused on assembly operations, disregarding economic and environmental benefits from optimising disassembly complexity. Herein, a functional characterisation of mechanical joint methods for the assembly and disassembly activities that take place throughout the product life cycle is proposed, focusing on open architecture products. Additionally, a classification of joining methods, a joint complexity metric valuation and a selection process are proposed for the conceptual design stage. The approach integrates both DFA and DFD principles in a formal methodology. The proposed selection roadmap can be implemented to increase product sustainability positively regarding resources optimisation, operational time and costs in reuse, remanufacturing and recycling tasks.

This paper describes two metrics to measure the complexity involved in assembly and disassembly tasks for open architecture products during its use phase. The approach proposed is based on the summary of all tasks required to assemble and disassemble a predefined set of modules to generate several product variants, which comprise different working levels or functionalities. The aim of the method is to provide a useful tool to designers in the analysis of product complexity regarding use and further phases in which the assembly and disassembly of modules are required. The benefits and usefulness of the metrics are oriented to enhance the sustainability performance of products through the measurement of complexity in modular systems for the decision-making during the design stage. The reduction of complexity involves significant benefits in all lifecycle phases of product, especially when the user or customer is responsible for many related tasks (maintenance, upgrading, reconfiguration and final disposal of modules). The metrics and their calculation process are illustrated using two case study products.

Sustainability is becoming an important topic in the society. Industries are adopting policies not only to comply with regulations but also to exercise social responsibility. As a result, academia is making efforts to prepare professionals with the knowledge and skills to facilitate sustainable solutions. Several initiatives to introduce sustainability in engineering education have been reported in the literature. However, the complexity and wide scope of sustainability make the teaching and learning of this subject a challenge. Sustainability can be defined from different perspectives and its balance between environment, economy and social pillars is not always preserved. Additionally, the existing instruments to assess sustainability knowledge are too general and no discipline specific. In a complex topic like this, the knowledge in different disciplines cannot be measured the same. This work presents an approach to develop assessment instruments to assess sustainability knowledge in engineering in a learning module to be introduced in a first year engineering design course. The tools will be designed to evaluate the effectiveness of the module and the performance of the students in the module.

Nowadays sustainable design is a mandatory requirement in the product development process. For this reason, design methodologies are addressed to establish a close relationship between environmental, social and economic impact indicators and product features from early design stages, especially in those features related to its manufacturing. In this paper, the design for manufacturing and assembly—DFMA methodology is adapted to sheet metal enclosure devices, integrating functional and component relationships to minimize particular sustainability indicators such as energy consumption, carbon footprint, number of parts, required amount of material, assembly time and manufacturing costs. Savings with the proposed method are achieved following specific sub-tasks oriented to define new simplified product components, considering changes in manufacturing processes and re-defining mechanical connections between parts. Traditional DFMA approaches consider manufacturing and assembly issues related to a reduction of product complexity and economic savings. The proposed method aims to examine the benefits in life cycle stages such as raw material consumption, service, maintenance, upgrading and end of life—EOL. The methodology is validated through a redesign of a sheet metal industrial clock, in which the sustainability impacts are calculated from a comparison of an existent product vs. a new product development. The implementation of the method in the case study demonstrate reductions of more than 25% in product mass, consumed energy and CO2 footprint, and more than 50% in theoretical assembly time and product complexity. Sustainability indicators of the proposed method are selected from literature analysis and taking into account attributes of sheet metal enclosure devices.
