On December 3, 2022, Antheia hosted its fourth clean-up in Pemukiman Muara Baru, marking our first open invitation to the public and social media. This inclusive approach led to an impressive turnout, where participants collectively gathered 1,114 kg of waste. A key part of this event was our #SayNoToStyrofoam campaign, which focused on reducing the use of harmful styrofoam products by raising awareness and promoting sustainable alternatives. The success of this clean-up highlighted the power of community action and reinforced our commitment to protecting the environment through informed and responsible choices.
