For manufacturing companies, the transition to circular business models (CBMs) can be hampered both by the lack of relevant data and by operational tools. Eco-design, associated with Industry 4.0 IoT (Internet of Things) technologies, can be an effective methodological approach in developing products that are consistent with the principles of the circular economy. The reason is that, in the design phase, decisions are made that can significantly influence the degree of sustainability of products during their lifecycle. Therefore, in the manufacturing environment, eco-design represents an innovative approach to include sustainability among the traditional industrial variables such as functionality, aesthetics, quality, and profit. This study aimed to test eco-design as a tool to define the equilibrium point between sustainability and circular economy in the manufacturing environment of ceramic tile production, and to demonstrate how new business opportunities can be created through evolution from a linear to a circular business model, thanks to IoT and Industry 4.0 technologies used as enabling factors. The main result of this paper was the empirical validation in a manufacturing environment of sustainability paradigms through eco-design tools and digital technologies, proposing the circular business model as an operational tool to promote the competitiveness of enterprises.

The purpose of this paper is to determine indices of environmental, economic and social sustainability related to the Italian production of ceramic tiles in porcelain stoneware in order to contribute to the construction of a reference benchmarking useful to decision makers, designers and end users of ceramic tiles. To achieve this goal, this paper is based on the Life Cycle Sustainability Assessment (LCSA) framework that incorporates the three dimensions of sustainability with cradle-to-grave Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and Social Life Cycle Assessment (S-LCA) tools. The study has shown that in the production of porcelain stoneware one of the major environmental problems, in addition to production in the strict sense, is the distribution system of the product to end users and, to a lesser extent but always significant, the process of supplying raw materials. Finally, it was highlighted that the joint use of the three impact assessment tools (LCA, LCC, S-LCA) requires further methodological work to avoid the risk of double counting of sustainability performance. This research has adopted a detailed methodological approach, both in the collection and in the processing of data, keeping the main phases of the production process separate. In this way, it has been possible to highlight that the major environmental criticalities are just beyond the “gate” of the ceramic factories, along the logistics chain. The study also proposes for the Italian ceramic sector not only indicators of environmental sustainability but also economic and social.

Purpose: The purpose of this paper is to analyse the production cycle of glazed porcelain stoneware, from the extraction of raw materials to the packaging of the finished product, with the aim of verifying the effects of integrating an environmental impact assessment into the decision-making process for managing the life cycle, to make it economically and ecologically sustainable, in a holistic approach along the supply-chain. Design/methodology/approach: The research is performed using the life cycle assessment and life cycle costing methodologies, to identify environmental impacts and costs, that occur during extraction of raw materials, transportation, ceramic tiles production, material handling, distribution and end-of-life stages within a cradle to grave perspective. Findings: Through the use of a comprehensive analysis of the environmental impact assessment and related externalities, three possible strategic options to improve the environmental performance and costs of ceramic tile production were formulated, leveraging sustainability as a competitive advantage. Research limitations/implications: This exploratory research opens future lines of investigation, the first of which is to confirm the technological feasibility and market responsiveness to the three strategic solutions hypothesised thanks to the use of an innovative eco-design technique. Originality/value: The research has allowed testing and validating the tools of environmental impact assessment (life cycle assessment) and economic impact assessment (life cycle costing as structured methodologies in a life cycle management framework, to help companies implement competitive strategies based on sustainability.

The purpose of this paper is to determine indices of environmental, economic and social sustainability related to the production of ceramic tiles in porcelain stoneware in order to contribute to the construction of a reference benchmark useful to decision makers, designers and end users of ceramic tiles. In Europe, the Italian ceramic industry is one of the most environmentally responsible sectors and has always been at the forefront of the adoption of innovative technologies and best practices, as well as regulations, towards the sustainability of processes and products. The main product of the Italian ceramic industry is porcelain stoneware, which is therefore the object of this study. To achieve this goal, this paper is based on the Life Cycle Sustainability Assessment (LCSA) framework that incorporates the three dimensions of sustainability with Life Cycle Assessment (LCA), Life Cycle Costing (LCC) and Social Life Cycle Assessment (S-LCA) tools. The sustainability analysis was initially carried out on a representative sample of about 15% of Italian porcelain stoneware production, then in order to identify the sustainability indices, the data were reconfigured to the functional unit of 1 m2 of ceramic product. In this way, the results will be comparable with other studies. The study has shown that in the production of porcelain stoneware one of the major environmental problems, in addition to production in the strict sense, is the distribution system of the product to end users and, to a lesser extent but always significant, the process of supplying raw materials. Finally, it was highlighted that the joint use of the three impact assessment tools (LCA, LCC, S-LCA) requires further methodological work to avoid the risk of double counting of sustainability performance. This research has adopted a detailed methodological approach, both in the collection and in the processing of data, keeping the main phases of the production process separate. In this way it has been possible to highlight that the major environmental criticalities are just beyond the "gate" of the ceramic factories, along the logistics chain. The study also proposes for the Italian ceramic sector not only indicators of environmental sustainability, but also economic and social.
