Waste battery collection rate was only 2%–5% in the EU, USA, and Australia by government and manufacturer-driven collection (Bae & Kim, 2021). The reason for this low collection rate is the lack of consumer awareness of recycling, the collection habit of consumers, and the tendency to resell electronics.
