This study is divided into two parts as a discussion, first part is to develop an integrated approach for a green product cradle-to-cradle (C2C) fuzzy recycling production planning model, and the second part is to analyze the wastewater discharge and a ZWD zero-waste-discharge planning is designed with resource lifecycle analysis for zero-waste-discharge planning in the pulp-and-paper industry. The first part of this study applies the failure mode and effects analysis technique and Taguchi experimental design method, develops a green product C2C performance evaluation system that considers the fuzzy impacts of environmental laws and regulations, green goodwill, and environmental efficiency of targeting countries, and decides both the optimal green production plan and estimated optimal lifecycle. In addition, the second part proposes model of ZWD zero-waste-discharge planning is established using the fuzzy comprehensive evaluation and Taguchi method to determine the overall wastewater recovery rate. The first part in this study compares the different degree of resource analysis in environmental regulations, and various recycling situations are simulated to demonstrate the successful applicability of the proposed model as well as the incentive policy for Taiwan, the USA and Bangladesh. However, in the second part, the best solution for zero-waste-discharge planning is 500 tons of clean water, recovery electrodialysis reversal is 345 tons, the wastewater reuse performance is 1.3 and waste heat recycling performance is 0.8. The results shows that the maximum overall wastewater recovery rate is 97.8 percent. The first value of this study is to construct a recycling production planning for resource lifecycle analysis, which is able to consider both the optimal combination of recycled components used and final green products produced with the maximum total resultant sales profit and to consider the potential failure phenomenon of recycled components adopted in the final product. Furthermore, the second value can solve in real situation, there is a need to address the qualitative information and qualitative data to carry out the optimal ZWD zero-waste-discharge planning in the pulp-and-paper industry.
