The HandyHeroes Project leverages the idea of “small repairs, big impact” through three key innovations: activating community-based talent (technician training), integrating community service with market mechanisms, and standardizing carbon reduction. These innovations address challenges such as service shortages in older residential communities, the lack of transparency in market-based repair services, and difficulties in managing household products without warranties. Currently, the HandyHeroes project provides services to over 450 residential communities across eight main districts of Xi’an, China. The model has also been adopted in 10 cities covering 100 communities nationwide, creating a low-cost, low-barrier, and sustainable approach to community micro-renewal and senior services. The Project’s achievement is reflected not only in carbon reduction metrics and tangible improvements to neighborhoods but also in raising public awareness that “repairing products is a form of environmental protection.”
