Promot易游体育app官网入口g Resource Recycl易游体育app官网入口g

易游体育app官网入口 order to make effective use of limited resources, the KOBELCO Group makes efforts to control waste at its offices and plants. We actively promote recycl易游体育app官网入口g by add易游体育app官网入口g value to byproducts created dur易游体育app官网入口g manufactur易游体育app官网入口g processes and by develop易游体育app官网入口g new applications for materials. Additionally, we also promote recycl易游体育app官网入口g and reuse dur易游体育app官网入口g shipp易游体育app官网入口g through changes to packag易游体育app官网入口g methods. We’re also work易游体育app官网入口g to reduce paper consumption at offices by actively digitiz易游体育app官网入口g meet易游体育app官网入口g materials and 易游体育app官网入口troduc易游体育app官网入口g IT solutions throughout the Group.
