Integration of green lean six sigma and TRIZ methodology for sustainable green manufacturing: a case study in plywood industry

Purpose The purpose of this paper is to present a case study in the plywood industry, aiming to demonstrate the successful integration of green lean six sigma (GLSS) and theory of inventive problem solving (TRIZ). Design/methodology/approach As a result of the integration of lean manufacturing, green production and six sigma, GLSS was developed. An innovative solution method such as TRIZ is needed to complement the performance of GLSS. A perfect combination of TRIZ and GLSS is looking forward to providing significant contributions in producing less waste, as a substantial factor to commit in green manufacturing for sustainability. Findings The industrial waste recycling rate was measured before and after the implementation of GLSS-TRIZ, that is 92%−93% and more than 95%, respectively. This proves that the GLSS-TRIZ has been evidently recognized as a powerful framework to achieve a green and sustainable manufacturing. Originality/value Sustainability has been a hot topic in the global manufacturing space for several years now. This focus on environmentally conscious practices is becoming increasingly prominent across various industries. With environmental concerns on the rise, green manufacturing is becoming increasingly important as manufacturers strive for more efficient and sustainable manufacturing processes. The past few decades have seen the emergence of innovative methodologies such as lean, green, six sigma, but addressing the entire sustainable development problem alone is not feasible. An organized and systematic method of problem-solving with analysis and forecasting techniques is performed to complement and realize a powerful methodology.
