Hilary Lewis joined Earthworks in July 2011 as the International Mining Campaign Fellow. She first became interested in the mining industry while researching environmental policy in the United States and Europe for ZAG International, a substitute raw materials provider for the cement industry. Her broader commitment to protecting the environment has led her in a variety of directions, most notably to found her own organization, Composting Toilets International, which seeks to spread the critical, inexpensive technology around the world.
Originally from San Francisco, Hilary moved east to attend Lehigh University in Bethlehem, PA. She graduated with a B.A. in Environmental Studies and International Relations and a minor in Latin American Studies.
