Owing to the increasing environmental awareness, firms are pursuing means in compliance with emerging related regulations. This study aims at resource recycling regarding to circular economy between sellers and buyers in case of deciding new products and recycled products as a part of raw material for remanufacturing. The decision of recycled products may reduce production costs and carbon emissions and achieve t he goal of recycling economy as well Regarding to the factors of carbon taxation and product recycling , two optimal ordering and remanufacturing production strategies with algorithms for solving the problem are formulated and n umerical examples are also g iven followed by sensitivity analysis for critical parameters. Conveniently , a simple interface system is designed to real time make decision s for users.
