Speakers, Organizers & Participants of the 2014 Seminar-Workshop on the Utilization of Waste Materials

The 2014 Seminar-Workshop on the Utilization of Waste Materials with the theme, "Sharing Knowledge, Technology and Expertise on Waste Utilization for a Sustainable Environment" was held on Sept. 5, 2014 at the 4th floor, Henry Sy Bldg, DLSU, Manila. The seminar-workshop which is is now on its 2nd year was organized by the DLSU Civil Engineering Department in cooperation with Tokyo Institute of Technology (TIT) , Association of Tokyo Tech Alumni and Research Scholars (ATTARS) and the Department of International Development Engineering Alumni Association (IDEAL). DLSU ChE Dept. faculty members also supported this activity.
