Abstract [en]

The annual accumulation of electronic equipment waste, including IT, in the European Union reached at least nine million tons in 2015. These products usually have a limited lifespan, and many consumers tend to buy new devices before their old ones stop working.

Remanufacturing is one of the effective ways to contribute to IT waste reduction. Product life extension through remanufacturing gives the product one or several more users throughout its life cycle. When remanufacturing is applied to laptops, the extraction of virgin materials, the energy consumption for manufacturing and the amount of waste are all reduced. However, today many remanufacturers of IT face challenges associated with inefficient and complex processes due to uncertainties in core timing, volume and quality. Lean remanufacturing is typically treated as an operations improvement strategy that deals with the process challenges. Just-in-time is one of the lean strategies to address inefficient, long and stochastic operations. Therefore, the aim of this paper is to investigate how just-in-time can help to reduce remanufacturing process lead time, and consequently increase process efficiency.

The data was collected through a focus group interview and a simplified Value Stream Mapping lean method at an IT remanufacturing company. The company’s remanufacturing process is assessed regarding process lead time and efficiency. Based on the case company's process challenges, the following possible just-in-time solutions were developed for remanufacturers: cellular layout, distinct product family flows and Kanban reordering system.
