On November 21, 2017, the European Union promulgated a new "Directive 2017/2102" in the Official Journal to amend the scope of regulation of "Directive 2011/65/EU" (RoHS 2 Directive). The RoHS 2 directive imposes restrictions on the use of certain hazardous substances in electrical and electronic equipment. The new directive mainly targets the operations of the secondary market for electrical and electronic equipment, including repair, parts replacement, refurbishment, reuse and transformation. EU legislators believe there is a need to assist the operation of such secondary markets in order to promote a "circular economy". "Circular economy" is a concept that has emerged in recent years. The purpose is to extend the added value of products as much as possible. Even if the products have reached the end of their life, these products or their parts can still be reused, thus reducing waste. The RoHS 2 Directive allows electrical and electronic equipment that is not regulated by Directive 2002/95/EC (RoHS 1 Directive) but does not comply with the provisions of Directive 2011/65/EU (RoHS 2 Directive). On the market until July 22, 2019. After that date, electrical and electronic equipment that violates the RoHS 2 directive will be banned whether it is placed on the market for the first time or for the second time. However, EU legislators now believe that banning the operation of the second market is inconsistent with the general principles behind relevant EU measures, including the circular economy, and therefore needs to be reconsidered. Therefore, the new directive states that if recycling takes place within an auditable, closed-loop business-to-business recycling system and the consumer is informed of the parts
