Development of landfill macro management policy is very important to sort out the MSW disposal drawbacks for any cities as a part of cleaner waste systems. This study emphasized on implementation of macro management policy of landfill for south asia zone through risk evaluation by using the approaches of Fuzzy Analytical Hierarchy Process (Fuzzy AHP), and Decision-Making Trial and Evaluation Laboratory (DEMATEL). For this purpose, Khulna city of Bangladesh was selected as case study area. To perform this study, drawbacks of MSW disposal of this city has taken into considerations from findings of the research gap, through focus group discussion (FGD) and expert’s opinions. Basing on the analysis, to achieve the desired goal four domains, twelve criterions and thirty factors were considered. Authority, reasoning, viability, and management were the four selected key domains. From the software analysis it is found that, among twelve selected criterions the most important criterions were legislative authority, negotiation with environmental act, value evaluation and risk management. Same way, among the thirty selected factors the most important influential factors were environmental assessment, approval of detail area plan, international environmental act, 40 year’s goal, and national risk found out through risk evaluation with respect to all domains. Study found out with the macro management policy of landfill is, authority> viability>management>reasoning. The developed policy is validated through casual relationship. ●The study is to develop macro management policy for new landfill as part of cleaner waste system.●Ranking of acceptable domains to develop policy from research gap and expert’s opinions.●Fuzzy AHP handles the experts’ vague judgments and assesses impact levels between factors and criterions.●Policy model developed by Fuzzy AHP as “authority>viability>reasoning>management”.●Reasoning, management causal variables authority, viability is effect validated by DEMATEL.
