Many foundries in Japan are working on environment measures aggressively and are showing excellent results. Specific examples of the measures in the foundries using green sand mold, self-hardening mold and full mold process etc…. For example, use of artificial sand, thorough local dust collection, decompression dust collection and general ventilation of foundries have achieved large effects to reduction of dust. Self-hardening sand with alkali phenol resin reduces bad smell, and factory ventilation by outside air induction has an effect on a summer heat measure. And there are foundries who achieve zero emission by recycling of used sand, dust, slag, used refractory and etc.
