東急不動產股份有限公司(總公司:東京都澀谷區,代表取締役社長:星野 浩明,以下稱「東急不動產」)與DIGGLE股份有限公司(總公司:東京都澀谷區,代表取締役社長:山本 清貴,以下稱「DIGGLE」)透過與DIGGLE的共創合作,在DIGGLE公司遷入惠比壽Business Tower(所在地:東京都澀谷區)的工程中,實現了內裝建材的「水平回收」。此舉將先前辦公室工程產生的內裝建材,透過材質回收再利用,製成環保再生內裝建材,並應用於另一處辦公室。
此項措施是東急不動產於2026年3月啟動的環境先進夥伴關係「team green」※1的環保政策之一,同時也為合作夥伴DIGGLE公司的永續發展活動做出貢獻。此外,作為東急不動產的環保行動,我們也對相當於DIGGLE公司辦公室工程面積十倍的區域進行了森林保育。
※1 環境先進夥伴關係「team green」是由東急不動產與認同環境保育活動的租戶企業共同組成,旨在解決環境課題、創造價值。詳情請參閱2026年3月24日發布的新聞稿(https://www.tokyu-land.co.jp/news/2026/001682.html)。
透過共創實現內裝建材水平回收,減少4.7噸二氧化碳排放量
在2025年10月至2026年2月期間實施的DIGGLE公司遷入工程中,我們率先採用了由再生材料製成的再生內裝建材(再生石膏板、再生地毯),實踐了「水平回收」。
再生內裝建材是透過材質回收技術,將廢棄的內裝建材再製而成。這能減少原料的開採、加工、運輸及製造等流程,有效抑制製造過程中產生的二氧化碳排放量。本次工程約減少了4,697公斤的二氧化碳排放※2。
此外,東急不動產也推動與利害關係人行動相應的森林保育措施。本次工程中,作為「team green」環保政策的一環,採用再生內裝建材,並對相當於DIGGLE公司辦公室工程面積十倍的4,633平方公尺的岡山縣西粟倉村森林進行了保育。此舉亦有助於保護生物多樣性及維持地區永續的自然環境。
※2 「二氧化碳排放量削減量」是根據製造商提供的數據,與傳統產品比較計算而得。

常見問題
What is "horizontal recycling" of interior building materials?
Horizontal recycling in this context refers to taking interior building materials from previous office constructions, reprocessing them through material recycling, and then using them as environmentally friendly recycled interior building materials in new office constructions. This differs from traditional recycling where materials might be downcycled or used for different purposes.
What specific recycled materials were used in this project?
The project utilized recycled gypsum board and recycled carpet tiles.
How much CO2 emissions were reduced by this initiative?
Approximately 4,697 kg of CO2 emissions were reduced, based on calculations comparing the recycled materials to conventional products.
What is "team green"?
"team green" is an environmental advanced partnership launched by Tokyu Land Corporation. It is a co-creative partnership where Tokyu Land and tenant companies collaborate to solve environmental issues and create value through environmental conservation activities.
Besides using recycled materials, what other environmental actions were taken?
Tokyu Land Corporation also implemented forest conservation measures. For this project, an area of 4,633 square meters in Nishi-Awa Village, Okayama Prefecture, was conserved, which is ten times the area of DIGGLE's office construction.
