A waste separation pilot project commenced in March 2020 covering the building at Gateway, the Administration block, University House and the Faculty of Economics, Management & Accountancy (FEMA) building.
The Quadrangle and Gateway outdoor areas were also part of this pilot project. In September 2025 new waste-separation bins for open spaces at UM were installed across Campus.
A number University buildings have been provided with waste-separation bins and work is underway to equip the remaining buildings with the appropriate bins for internal use.

In light of the objectives for the European Week for Waste Reduction (EWWR) 2025, the University of Malta participated in this week of events, through three main activities, promoting reuse of goods. The focus of the EWWR events held at the UM Msida Campus was on the reuse of clothes and books.
Read about the three events organised:
C-SUM held meetings with food operators on campus to lower and eliminate single-use plastics in catering. A number of food operators have been actively promoting reusable bamboo cutlery and cups.
