Campus Tumbler Day Returns, Now LocknLock Campaigns for Environmental Concerns at Atma Jaya University

As a continuity of eco-friendly living campaign targeting young generation, LocknLock held Campus Tumbler Day at Atma Jaya. The activity, which was a continuation of Campus Tumbler Day at the University of Indonesia, was held on 18 October 2024. Elevating the issue of reducing single-use plastic bottles, LocknLock provides environmental education to students through fun activities.

The activities include selling booths of LocknLock and Oatside, coffee class, and trade in promo for disposable plastic bottles or used tumblers of any brand. The coffee class not only offered a fun experience of making café-style coffee at home, but also served as an invitation to students to always bring a tumbler anywhere and everywhere as a concern for the environment and to support a modern lifestyle.
