Social Design Green Project Home Composting System by Han Gao Green Project aims to create a pleasing experience for home composting and attract more Bay Area participants. The designers collaborated with Rodgers Ranch Farm to gain knowledge about composting and collect user feedback. Green Project provides a Kitchen Grinder for solving the difficult problem of preparing food waste and a three-bin Backyard Composter to speed up the process. The composter features a rotating design that increases airflow, creating an optimal compost environment. It also has a water tank base for stability and convenience when adding moisture to the compost.
