Environmental Service Centers (ESC)




The Environmental Service Center (ESC) was opened to make the disposal of household hazardous waste easier. Two locations are available to accept Household Hazardous Waste and other materials such as Batteries, Oil, Paint, Antifreeze and electronic waste at no additional charge to City of Houston residents.



Both the North and South ESC locations provide a drive through, drop-off site for Houston residents to bring their Household Hazardous Waste (HHW) items. A Voucher or prepaid user program is also available to residents of surrounding areas.  Call 713-551-7355 for more details.

Safety First!
The ESC is not responsible for damage caused by faulty packaging.


For your safety and to make the collection of materials less costly and more efficient, if you have a product that is still usable, consider giving it to someone who can use it.


Do not transport chemicals in the passenger compartment of your vehicle; put them in the trunk.
Before moving or transporting certain chemicals (especially those not typically used in the average household), it is helpful to search online for their chemical nature. Simply shaking, agitating or exposing to heat could cause an explosion. Picric Acid which is a dangerous explosive and toxic chemical (especially dangerous in crystal form) can be found in some homes and garages. This type of commercial grade chemical should only be handled by highly trained chemical waste companies. The ESC will not accept chemicals of this nature. Remember to be safe... for yourself and for your loved ones.
