In recent years, reducing CO\u2082 emissions across the entire product life cycle and addressing resource circularity have also become important themes. The optical resin &#8220;Iupizeta EP&#8221; is an optical resin that meets these requirements while contributing significantly to CO\u2082 reduction as a sustainable material.<\/p>\n\n\n\n<p>In the injection molding of lens parts, sprues and runners (scrap material generated during molding) are produced in addition to the actual products. For Iupizeta EP, we have launched an initiative to recover these materials\u2014which could conventionally have been treated as waste\u2014from our customers and recycle them.<\/p>\n\n\n\n<p>Please contact us if you are interested in sustainable materials.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"498\" src=\"https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/7e739e76dfef1ed986f56d11938a4e79-1024x498.png\" alt=\"\" class=\"wp-image-626\" srcset=\"https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/7e739e76dfef1ed986f56d11938a4e79-1024x498.png 1024w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/7e739e76dfef1ed986f56d11938a4e79-300x146.png 300w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/7e739e76dfef1ed986f56d11938a4e79-768x373.png 768w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/7e739e76dfef1ed986f56d11938a4e79.png 1199w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"325\" src=\"https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/0b44b2517d89fd8e44aea94f2dd88d3e-1024x325.png\" alt=\"\" class=\"wp-image-627\" srcset=\"https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/0b44b2517d89fd8e44aea94f2dd88d3e-1024x325.png 1024w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/0b44b2517d89fd8e44aea94f2dd88d3e-300x95.png 300w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/0b44b2517d89fd8e44aea94f2dd88d3e-768x244.png 768w, https:\/\/iupizeta.mgc.co.jp\/cms\/wp-content\/uploads\/2026\/05\/0b44b2517d89fd8e44aea94f2dd88d3e.png 1195w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-embed is-type-wp-embed is-provider-iupizeta-ep-ep wp-block-embed-iupizeta-ep-ep\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"wp-embedded-content\" data-secret=\"RBNbdC57aM\"><a href=\"https:\/\/iupizeta.mgc.co.jp\/en\/contact\/\">Contact<\/a><\/blockquote><iframe class=\"wp-embedded-content\" sandbox=\"allow-scripts\" security=\"restricted\" style=\"position: absolute; visibility: hidden;\" title=\"&#8220;Contact&#8221; &#8212; \u3042\u306a\u305f\u4ed5\u69d8\u306e\u5149\u5b66\u6a39\u8102 Iupizeta EP\uff08\u30e6\u30d4\u30bc\u30fc\u30bf\u00aeEP\uff09\" src=\"https:\/\/iupizeta.mgc.co.jp\/en\/contact\/embed\/#?secret=VC4lhqOMLR#?secret=RBNbdC57aM\" data-secret=\"RBNbdC57aM\" width=\"500\" height=\"282\" frameborder=\"0\" marginwidth=\"0\" marginheight=\"0\" scrolling=\"no\"><\/iframe>\n<\/div><\/figure>\n","protected":false},"featured_media":543,"template":"","meta":{"_acf_changed":false,"_locale":"en_US","_original_post":"https:\/\/iupizeta.mgc.co.jp\/?post_type=column&p=509"},"column_tax":[78],"class_list":["post-601","column","type-column","status-publish","has-post-thumbnail","hentry","column_tax-trends","en-US"],"acf":[],"_links":{"self":[{"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/column\/601","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/column"}],"about":[{"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/types\/column"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/media\/543"}],"wp:attachment":[{"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/media?parent=601"}],"wp:term":[{"taxonomy":"column_tax","embeddable":true,"href":"https:\/\/iupizeta.mgc.co.jp\/wp-json\/wp\/v2\/column_tax?post=601"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
