This paper aims to develop a multiproduct closed loop supply chain model for an Indian kitchenware firm to address their integrating issues between multiple channels take into consideration the environmental and economic sustainability. IBM CPLEX optimiser is used to solve the model for minimising the transportation cost between various stages of supply chain.
