The Diliman Environmental Management Office (DEMO) was formally approved by the Board of Regents on July 31, 2019. Formerly known as the Task Force on Solid Waste Management (TFSWM), DEMO now has more tasks and a larger scope of responsibilities.

Formed on July 21, 1999, TFSWM was formed in order for the University to cope up with a very serious garbage problem at that time – the scheduled closure of the Payatas dumpsite in December 1999 [Administrative Order No. CTL-99-25]. Its main objective then is β€œto provide the entire UP Diliman community an alternative means of effective solid waste management [and] address all programs and issues pertaining to campus waste management.”

Upon its creation, the TFSWM is under the supervision of the OVCCA and was previously operating under the Office of Community Relations. Prof. Armando T. Basug was appointed as the first Head of TFSWM.
