The project 'Djamu' appears to be a legitimate but early-stage social enterprise focused on upcycling bottle caps in Indonesia, confirmed by the existence of djamu.com.au. However, the submission itself contains severe red flags that drastically reduce the score. Claims such as 'audience reach: everyone' and 'most people have used my product' are demonstrably false for a niche furniture brand. The revenue figure uses incorrect terminology ('marketcap') and provides an ambiguous number. While the mission has high real-world utility, the lack of verifiable traction and the poor quality of the submission (e.g., user name 'IronFang', hyperbolic claims) result in a score reflecting minimal proven usefulness.

Description
We have found that bottle caps can be repurposed saving waste, providing jobs and delivering opportunities for dignified work that can raise individuals, families and potentially communities out of poverty. Each year more than 75 billion beverage bottle caps are made in Indonesia and more than 350,000 informal waste workers work in Jakarta alone. Informal waste workers still remain largely unacknowledged for their contribution to waste management in Indonesia. DJAMU partners with waste workers to create a solution for this waste product, a filament made from bottle cap waste recovered from landfill that can be woven into furniture and basket ware.
