From January 25 to March 25, 2024, the second phase of the HUSM Sustainability Competition was conducted. This challenge included various activities designed to engage and inspire sustainable practices within our community. One of the key activities was creating a tree made entirely from recyclable items in our laboratory. This creative initiative promoted recycling and encouraged innovative thinking about waste materials and their potential for reuse. Through such activities, the Sustainability Committee aims to create a culture of environmental responsibility within our department and contribute to the broader goal of a sustainable future. We welcome the involvement and support of all community members in this important endeavour.
