Kathi MirzaKathi Mirza

I am passionate about waste reduction, and always open to an honest conversation about reduce, reuse, repair, recycling, composting, consumption behavior and trash. I love reuse (40+ years), composting (25+ years), deep dives into shared responsibility as well as resource conservation. I hold a B.S degree from the Carroll School of Management at Boston College and an M.A. in Urban and Environmental Policy from Tufts University. For 20+ years I’ve served as a Regional Coordinator for MassDEP’s Bureau of Waste Prevention, and I have been honored to volunteer in many communities I’ve lived in, from San Francisco to Boston.
