Circular Economy (CE)

To enable the sustainable use of finite resources, we consider everything—not only materials, products, and waste, but also nature itself—as a resource.
We promote the effective use of resources throughout the entire product lifecycle by taking a multifaceted approach encompassing a wide range of initiatives. These include promoting reuse and recycling, introducing bio-based materials, utilizing byproducts, and implementing upcycling.
We also actively utilize natural resources, aiming to realize a sustainable circular society.

In the mold-making process for product forming, lump-shaped waste material was generated daily during equipment startup. By revising the number of test shots and discharging the material in a form closer to the final product, we enabled material crushing and reuse, achieving effective resource utilization.

With a view to reducing both CO₂ emissions and new material procurement volume, we reuse runners formed during the resin molding process for electronic throttle gear sub-assemblies.
We pulverize the runners for reuse as a recycled material in resin molded products.

At the Aisan Future Factory, we have established an energy circulation system^* that utilizes an aquifer 90 meters underground as a thermal storage tank. By storing the cold and heat discharged from air conditioning systems in underground aquifers and utilizing this stored thermal energy seasonally, it is possible to reduce air conditioning energy consumption by approximately 50%.
