An environmental load information cooperation system for supporting management on an environmental load caused when remanufacturing a recycled product using a recyclable part through one or more processes, the environmental load information cooperation system comprising: a memory; and a processor, wherein the memory stores processing information that is accumulated by associating information indicating recycling processing performed in each of the processes for recycling the recyclable part, information indicating a processing purpose corresponding to the recycling processing, and information indicating an environmental load caused by the recycling processing, acquired when remanufacturing the recycled product, with a recycling identifier for individually identifying remanufacturing of the recycled product and a part type of the recyclable part, and the processor receives designation of a target part type that is a part type to be analyzed, characterized in that the processor extracts, from the processing information, a permutation of one or more types of recycling processing performed consecutively on the recyclable part corresponding to the target part type in remanufacturing the recycled product, as a processing pattern for each processing purpose, gives a priority to the processing pattern from a viewpoint of reducing the environmental load for each processing purpose based on a representative value of the environmental load for each processing purpose, and presents analysis result information how much an environmental load is improved by adopting the processing pattern based on the priority for the processing pattern. a memory; and a processor, wherein the memory stores processing information that is accumulated by associating information indicating recycling processing performed in each of the processes for recycling the recyclable part, information indicating a processing purpose corresponding to the recycling processing, and information indicating an environmental load caused by the recycling processing, acquired when remanufacturing the recycled product, with a recycling identifier for individually identifying remanufacturing of the recycled product and a part type of the recyclable part, and the processor receives designation of a target part type that is a part type to be analyzed, characterized in that the processor extracts, from the processing information, a permutation of one or more types of recycling processing performed consecutively on the recyclable part corresponding to the target part type in remanufacturing the recycled product, as a processing pattern for each processing purpose, gives a priority to the processing pattern from a viewpoint of reducing the environmental load for each processing purpose based on a representative value of the environmental load for each processing purpose, and presents analysis result information how much an environmental load is improved by adopting the processing pattern based on the priority for the processing pattern. extracts, from the processing information, a permutation of one or more types of recycling processing performed consecutively on the recyclable part corresponding to the target part type in remanufacturing the recycled product, as a processing pattern for each processing purpose, gives a priority to the processing pattern from a viewpoint of reducing the environmental load for each processing purpose based on a representative value of the environmental load for each processing purpose, and presents analysis result information how much an environmental load is improved by adopting the processing pattern based on the priority for the processing pattern.
