<p> During the Hokkaido Eastern Iburi earthquake that struck in September 2018, Hokkaido realized the vulnerability of its centralized energy systems through failures such as large-scale blackouts throughout the prefecture. It was reported that owing to the blackouts, the dairy industry, which is the key industry of Hokkaido, was forced to discard about 20,000 tons of raw milk, with the total damage amount reaching approximately 2 billion yen. To prevent such damage, Hokkaido must build a stable energy infrastructure by introducing autonomous distributed energy.</p><p> To this end, this study aims to build a “recycling-type community model” that would achieve the following: regional independence through renewable energy, reduction of CO2 emissions, complete recycling of waste, and the establishment of autonomous dairy management. The role of dairy management would be to analyze and evaluate on the “recycling-type community model” on the basis of the following three perspectives: “material recycling, ” which refers to local production and consumption, “environmental nature, ” which indicates the effect of CO2 emission reduction, and “economy, ” which indicates the effect of investments influencing stability.</p><p> Three effects can be extracted from the results of the studied model: self-sustainment (local production and consumption) of the annual energy usage can be facilitated by building a “recycling-type community model, ” utilizing the model will positively contribute to the reduction of CO2 emissions (2,110.2 t of CO2 per year) and the use of waste (livestock manure 34,500 t), and the model can recover its construction cost in 11 years, thereby enabling independent management of biogas plant (BGP) facilities and livestock.</p>
