Waste reduction through Kaizen approach: A case study of a company in India

Abstract

The growth in manufacturing activities for economic development is putting a lot of pressure on the environment. One such impact is due to generation of waste from hazardous material. The best way for hazardous waste management is either elimination or substitution with non-hazardous material. The case study in the present paper is focused on the problem of hazardous waste reduction in absence of non-hazardous substitution. In absence of any non-hazardous substitute of hazardous material, waste generation can be reduced using improvement techniques such as Kaizen to improve the manufacturing process. An Indian company improved the manufacturing procedure with very low cost to reduce waste generation of hazardous material. The outcome of this Kaizen project is the reduction of waste by 13.8% at very low cost. Along with waste reduction, cost saving, and other resource savings are another benefits. This case study provides insight about the use of Kaizen for environmentally sustainable manufacturing.
