Abnormal wastage in production can be due to a number of factors, including poor quality raw materials, incorrect or inefficient production processes, and damaged or defective products. In order to reduce abnormal wastage, it is important to identify and address the root causes. For example, if poor-quality raw materials are causing defects in the finished product, sources for these materials must be identified and replaced.

Similarly, if production processes are inefficient or not well-suited to the needs of the product, they should be updated or redesigned. Finally, if damaged or defective products are being produced, measures should be taken to ensure that these products are repaired or recycled rather than discarded.
