Abstract: Every industry has to ensure a quality check so as to ensure that the products manufactured by them are safe for the consumers. During this process, a lot of wastage occurs due to rejection. Because of this rejection a lot of time, money, resources and manpower are wasted. This research work focuses on minimising this rejection and also to ensure maximum recovery from the rejected material by Poka Yoke. Furthermore, the rejected products from a parent company are smuggled and sold in the market without the parent company's notice, thereby spoiling their reputation. To elude this situation, hallmarking by engraving technique is also suggested. This helps in maintaining accountability of the rejected goods and also in preventing them from reaching the black market.

Keywords: non-conformities; waste recovery; scrap reduction; safe disposal; hallmarking; Poka Yoke; engraving.
