Improving the manufacturing process of kitchen furniture with a sustainable perspective

The concept of sustainability concerns the ability to satisfy current needs without compromising the possibility for future generations to satisfy their own needs. Over the years this concept turned out to be an essential theme for many industries because of a spread and heightened sensitivity towards environmental protection and social responsibility. Nevertheless, every firm still needs to guarantee the economic viability of its actions and retain its competitive advantage over competitors to remain in the market. This idea corresponds to the triple bottom line approach, according to which the business performance should be monitored from three perspectives, namely economic, environmental, and social. From one side sustainability means the integration of multiple practices, whereas on the other side, the current globalized and competitive economy requires enterprises to combine sustainability with practices of Industry 4.0 to contribute to Circular Economy objectives. The aim is to make choices that improve all three aspects. This work proposes an approach able to involve all three pillars of sustainability and the forefront tools to evaluate them. The case study presents the improvement of the manufacturing process for kitchen furniture. The aim was to create a smart working environment able to increase productivity and mitigate ergonomic risks ensuring a reduced environmental impact. Four parallel manual assembly lines were replaced with one semi-automated line, in which some specific workstations can adapt the product position to the operator's anthropometric measures. The re-design of the workplace allowed both the reduction of out-of-quality pieces and the enhancement of worker well-being. The main results show the achieved optimization for each pillar.
