Abstract
Achieving triple bottom lines (TBL) throughout a product's life cycle is important in sustainable products and services. However, existing studies address the aspects of TBL partially, considering only a few stages of the product life cycle. Therefore, we propose a sustainable product development and service (SPDS) approach to address the entire product life cycle in two phases, namely product development and service phases. The former comprises product design and manufacturing stages, whereas the latter involves multiple stages, such as product distribution, retail, use, maintenance, and end-of-life. The two phases connect and interact logically to attain the TBL. The proposed SPDS approach was used to develop a sustainable industrial LED lighting product and service that exhibited prominent environmental, social, and economic performances. The environmental impact of the new product was 46% lower than that of the existing product with the same light output. Additionally, cost savings increased up to 14% per year with the leasing service, which promotes workers’ welfare, reduces cost for the manufacturers, and generates a healthy recurring profit stream. Thus, the application of the novel SPDS is innovative and highly beneficial.
