With the development of network technology, the industry has improved product quality and productivity by adopting digitalization and automated testing and production through the Internet of Things (IoT). As every household uses electricity, it has an electricity meter to measure the amount of electric energy. Taiwan Power Company has installed electricity meters with a mechanical and analog system. However, smart technology needs to be introduced to the meter, which replaces the existing ones. However, it is a waste of resources to discard tens of millions of previous meters, which does not meet the needs of a circular economy. Therefore, it is required to find a way to use the previous electric meters with an innovative and creative adjustment. This research verifies the possibility of recycling the glass cover of the mechanical analog meter to cooking glassware. The composition of the glass cover and heavy metal analysis of dirt on the surface revealed that it is appropriate for cooking and heating. The test results show that the glass cover is suitable for cooking in a microwave oven but not on an electric ceramic cooker (hot plate). In conclusion, this study proposes a possibility to recycle the glass cover after cleaning and attaching a new logo.
