Costa Rica


Improper waste management in squatter communities in Costa Rica poses health risks to humans and degrades the environment. We worked with Un Techo Para Mi Pais to address the need for improved waste management in these communities. Using data on waste practices from site assessments, survey analysis, and personal communications, we developed a manual on feasible waste management options. For solid waste, a combination of composting, recycling, and municipal collection reduces waste volume at a reasonable cost. For human waste, composting latrines are low cost, use minimal space, and produce a usable product. We hope that these waste management strategies will improve living conditions in squatter communities in Costa Rica and throughout Latin America.
