City of Houston residents must use the City of Houston Environmental Service Centers. Reusable building materials can go to the City of Houston ReUse Warehouse (281-814-3324).

Good to know

Pack items in a box or plastic bin, not a trash bag. Keep lids tight and labels on. Do not mix chemicals or combine half-full containers. Keep pool chemicals away from gas, oil, paint and cleaners, and keep bleach away from ammonia. Put the box in the trunk or truck bed. Broken fluorescent bulbs can go in your trash.
