Decoupling natural resource use and environmental impacts from economic growth

Over the past 10 years, the concepts and objectives of circular economy have been increasingly detailed and become strategic issues of international, European, and national policies. However, the transition towards circular production models continues to be affected by several barriers and critical factors that make the transition difficult to achieve. The paper tries to design a relationship between sustainable production and lean production, highlighting the opportunity to invest in reverse‐logistics and how Industry 4.0 system represents a breeding ground for circular economy targets application. The aim of the current study is to examine the relationships among sustainable production, lean production, and Industry 4.0 in order to evidence the need to adopt a lean methodology and Industry 4.0 technologies in a sustainable development perspective for companies. Following a holistic vision, the authors summarize the production principles and formulas, which, although in parallel, lead to similar results and therefore represent the pillars of a competitive and sustainable business. In conclusion, exploring the circular economy principles and production chain model, challenges, opportunities, and future outlooks are formulated.

Enabling the Circular Economy transition: a sustainable lean manufacturing recipe for Industry 4.0

Sustainable performance is expected to become a major factor when examining the feasibility of a construction project in terms of its life cycle performance. The study on which this paper is based developed a simulation model, using system dynamics methodology, to assess the sustainable performance of projects. Three major factors are used to examine project sustainable performance (PSP): the sustainability of economic development (E), the sustainability of social development (S), and the sustainability of environmental development (En). Sustainable development ability (SDA) was used as a prototype to evaluate the case. This paper explains and demonstrates the procedures used to develop the model and finally offers an approach for assessing the feasibility of a construction project in terms of its sustainable performance.

With the rise in population and urbanization, the demand for affordable housing and other infrastructure is increasing, especially in developing countries. In this context, the incorporation of technology that ensures faster and cheaper construction of structurally sound structures in a safe working condition is gaining relevance. 3D printing is one such technology in which the building material is extruded layer by layer to create the structure of the desired shape. This technique is gaining importance in the construction sector recently due to its advantages in reducing the cost and time of construction. In this background, it is also important to evaluate the long-term sustainability of structures built with 3D printing techniques which in turn is affected by the potential materials that is used to print. Therefore, this study is an attempt to compare two parameters closely related to environmental sustainability, namely thermal comfort and building energy efficiency of residential buildings built with 3D printable concrete, M25 concrete and conventional brick masonry. The results indicate that the performance of 3D printable concrete as the building envelope is lowest in both these criteria, in comparison to other materials. This necessitates further experimental studies in this domain and improvement of materials used for 3D printing in order to address the concerns of sustainability associated with using it in construction. The study, therefore, enlightens on the relevance of examining the sustainability performance of a new technology being implemented in the construction sector to prevent long-term negative environmental impacts.

A simulation-based investigation of sustainability aspects of 3D printed structures

The growth of the construction industry has been constantly challenged by issues such as low productivity, time overruns, reduced profits, and high variability. Additionally, growing emphasis on sustainable development challenges the industry to explore methods and technologies that improve the sustainability of construction and built systems. Lean construction is proposed as a solution to address many of the construction related issues by reducing wastes and improving reliability, and recent research reveals that, it has significant potential in addressing sustainability concerns as well. Therefore, the relationship between lean and sustainability warrants a deeper understanding to assimilate the trade-offs across economic, social and environmental parameters. Even though the existing studies in this domain establish the relationship between lean and sustainability, they are greatly diverse in their approaches thus creating a fragmented understanding, and does not collectively analyse the various interrelationships and the feedbacks. This mandates the need of a realm like systems thinking to capture the dynamicity and interlinkages embedded in this complex relationship. This paper proposes a conceptual framework based on system dynamics modeling approach for the integration of lean and sustainability. A systems approach provides a better understanding to the industry practitioners about the scale of lean implementation demanded to ensure sustainable development.
