Abstract

<p>Universities discharge various kinds of waste from activities such as education, research and medical care. This waste should be disposed of safely, with consideration for environmental conservation and public health, and according to relevant laws. Therefore, universities in Japan have the treatment facilities on campus for the waste from experimental facilities since the 1970s, but the number of facilities decreased due to dioxin problem. Spray combustion system is a primary treatment of organic liquid waste and the treatment equipment with measures against dioxins is currently running. For the treatment of inorganic liquid waste, ferrite treatment, coagulation-sedimentation method and iron-powder treatment are mainly used to combine pretreatment or post-treatment. The Academic Consociation of Environmental Safety and Waste Management provided information and data on waste management at universities and made a manual on external consignment of waste cooperating with waste-related companies in order to improve each other. As a result of efforts of universities and waste-related companies over 40 years, the treatment of waste discharged from universities could be made appropriately. Hence, regardless of on-campus and off-campus (external contractor) waste treatment, the waste from universities should be properly managed and treated in compliance with relevant laws. An organization such as a Center is indispensable for management and operation. It is also important for faculty members and students to realize their responsibility as generators of waste from the educational viewpoint.</p>
