OrganicPulse Districts is a mobile-first circular-economy marketplace that turns everyday household dry waste (eggshells, coffee and tea grounds, cardboard) into verified, AI-matched donations for local organic manure manufacturers and terrace gardeners. The problem: households throw away dry organic matter that's genuinely useful raw material for making manure and compost, while nearby manure manufacturers and gardeners pay for inputs they could be getting locally, for free. There's no trustworthy, low-friction way to connect the two sides, and any real solution has to work without assuming anyone owns a weighing machine or wants to fill out forms. OrganicPulse Districts closes that loop with three role-based portals in a single installable PWA. Households sort their dry waste into three categories at home and carry a QR pass. A neighborhood collection partner scans that pass at a weekly drop-off point, confirms in person which categories are present, and photographs the caddy, since manual weighing isn't realistic door-to-door. That confirmation is verified by Meta's SAM 3.1 and immediately credits the household with Green Points. Behind the scenes, Meta's Muse Spark model acts as a matching agent: it reasons over live inventory and active demand from receivers, decides who a new batch should go to, and writes a plain-language explanation the receiver actually reads before claiming it. Receivers can also browse a live inventory marketplace directly or proactively place a requirement. The result is a trust-verified, AI-routed supply chain for organic waste that a household, a volunteer collection partner, and a small manure business can all use from a phone, with zero new hardware and zero manual bookkeeping.
