Mambruk Anyer Hotel as one of the projects of Griya Idola, together with SITH ITB developed an environmentally friendly waste management method using the Black Soldier Fly (BSF) larvae. The program inauguration was held on Thursday, November 6, 2019 at Mambruk Hotel Anyer.

Also carried out was the launching of the BSF monthly scheme, with the year-end target being "Green and Sustainable Resort". BSF itself is a South American tropical insect with the ability to digest all types of organic waste and has the ability to survive without food. The bioconversion process of these insects produces organic residues with high nutrient fertilizer content which at the same time the larvae can be processed into chicken and fish feed. By using natural materials, this method can improve the concept of processing waste into an environmental preservation program. The BSF program is Griya Idola's dedication to substantial actions to achieve sustainable environmental preservation.
