Household hazardous waste San Antonio: drop-off locations and rules

What counts as household hazardous waste?

San Antonio’s Solid Waste Management Department says household hazardous waste should never go into any curbside cart. It directs these materials to HHW drop-off centers instead. The accepted list includes automotive fluids, batteries, paint, pesticides, cleaners, solvents, cooking oil and electronic waste. Read the city’s HHW guidance.

Begin with a written list of what is actually in your garage, shed or cupboard. Include the product name, how much remains and whether the original container is intact. Check each entry against the city’s current list rather than assuming all liquids or all electrical items have the same destination.

This guide covers household drop-off planning. If a product is unidentified or a container has deteriorated, ask the department for instructions before transporting it. A general accepted category does not answer every question about a damaged container or an unusual substance.

Who can use the service, and what documents are required?

The city requires a recent CPS Energy bill showing payment of the Environmental Fee and picture ID. Those are two required checks, not alternatives. Put both documents with your trip checklist before loading the car. A utility bill without the relevant fee may not resolve eligibility. Official document requirements.

The city’s billing guidance says some apartment residents pay the Environmental Fee and can access drop-off centers. If you do not receive the CPS Energy bill yourself, ask the Solid Waste Management Department what documents apply to your household. Do not assume a landlord’s bill or lease replaces the published requirements.

For eligibility, document or appointment questions, contact the Solid Waste Management Department at 3-1-1 or 210-207-6000 before visiting. Explain your billing situation and ask what to bring and whether you need to arrange the visit. Published department contacts.

Culebra drop-off location and opening hours

These are the hours shown on the current HHW page as of November 12, 2026. Saturday has an earlier finish than weekdays. Plan the trip around the facility schedule rather than your regular household collection day, and allow time to follow the site’s entry and unloading directions.

The HHW page specifically excludes holidays from its regular opening hours and links the city closure calendar. Check the city holiday and closure information before a holiday trip. The calendar also points to detailed holiday service announcements; use those when you need to establish whether a particular service is operating.

Do not rely on an older printed waste guide for current hours or paint quantities. The current department page gives the hours and limits used here. If you find a different time elsewhere, ask the city which instruction applies to your planned visit. Current Culebra listing.

Monthly and quarterly HHW drop-off events

San Antonio lists monthly HHW events at Bitters Bulky Waste Collection Center, 1800 Wurzbach Parkway, 78216. The event page supplies individual dates and 8 a.m.–noon times. Use the dated listing rather than assuming a generic first-weekend rule covers every month. Open the monthly event calendar.

The monthly page’s general description and its individual dates do not fully align: some months show Saturday only, while others list Friday and Saturday. For a particular visit, check that exact date or call the department. Do not travel on an unlisted Friday based only on the general description. Read the dated entries.

Quarterly events have a separate listing at 2755 Rigsby Avenue, San Antonio, TX 78222. The page publishes individual dates with 8 a.m.–noon times and labels the cost free. Use it to confirm the event you intend to attend; this is not a daily chemical drop-off schedule. Quarterly event details.

The monthly event listing also labels its cost free. These statements verify event pricing, not a universal exemption from the eligibility and load requirements. Check the main HHW guidance alongside the event listing, particularly if you are unsure whether your household documents qualify. Monthly event cost; main requirements.

Accepted and not-accepted items

The following categories come from the current city HHW page. They help you separate a household chemical load from ordinary trash, commercial waste and medical items before making a trip. For something not clearly listed, ask the department instead of treating silence as acceptance. Full official accepted and excluded lists.

For tires, appliances and construction materials, check the city’s separate bulky waste collection center guidance. Its accepted list includes those categories, subject to limits. Confirm the correct receiving service before combining a bulky load with HHW, even where the services share an address. Our San Antonio bulk trash guide covers larger items.

Paint disposal, liquid limits and the weight cap

San Antonio limits paint and other liquid waste to five 5-gallon cans or twenty-five 1-gallon cans. It separately limits HHW materials to 220 pounds. Check both the container allowance and total weight before planning your visit; the page does not describe the liquid allowance as additional to the weight cap. Current liquid and weight limits.

An inventory is useful when several partly filled cans have accumulated. Record the can sizes rather than guessing a total from how full the vehicle looks. If you have mixed container sizes or are close to the maximum, ask the department how it applies the published allowance.

The city accepts paint, but a general paint listing does not settle every question about condition or packaging. Our paint disposal guide can help you organize the task. Follow San Antonio’s local requirements for the actual drop-off rather than another city’s quantities or preparation advice. Paint acceptance and preparation.

Do not combine different chemicals to reduce the number of containers. The city explicitly says not to mix materials in the same container or bag. If you have more than the published allowance, ask for a compliant disposal plan instead of arriving with an unconfirmed oversized load. No-mixing rule.

Battery recycling and electronics recycling near me

The city includes batteries and e-waste in its accepted household categories. That gives you an official starting point for battery recycling and electronics recycling near me searches. The page does not specify every device model, battery chemistry or damaged-battery condition, so check unusual items before traveling. Battery and e-waste acceptance.

Keep a separate list of devices and batteries rather than calling the whole box “electronics.” For example, ask about a damaged battery as its own item. Include its condition when you contact staff, and request packing instructions suitable for that condition. This avoids assuming one general collection category answers every handling question.

The current HHW page also lists fluorescent light fixtures and ballasts, along with printer cartridges. Read those categories literally and ask about a bulb or electrical item that is not clearly described. A familiar recycling symbol or a nearby collection address is not a substitute for the city’s acceptance check. Read the exact material wording.

Medicine, sharps, business waste and other exclusions

San Antonio excludes medicine, commercial waste and medical waste from HHW drop-off. The city’s services guide, pages 11 and 20 points medication users to SAWS MedDropSA. Confirm a current medication collection location with the Solid Waste Management Department before traveling; do not infer medicine acceptance at every HHW event.

For sharps, a January 14, 2026 city announcement describes the District 1 and Corazón Ministries collection pilot. It publishes 210-207-0900 for District 1 program questions. Ask that office for current disposal instructions before transporting needles. The HHW program’s medical-waste exclusion still applies.

Waste generated by a business does not become eligible household waste because you bring it from home. Commercial waste is excluded. Tell the department how the waste was generated so it can direct you to an appropriate process, rather than entering the residential line with workplace products. Commercial waste restriction.

Keep tires apart from household chemicals. The city’s bulky drop-off page lists car tires, large appliances and qualifying construction materials under a separate service. Check its current conditions and ask the department which receiving area to use. Our tire disposal guide can help you organize that question.

Step by step: prepare and complete your visit

1. List each material and compare it with the official accepted and not-accepted categories. Ask about unclear items before loading.
2. Choose Culebra or an individually listed collection event. Check current hours, holiday exceptions and any appointment question with the department.
3. Bring a recent CPS Energy bill showing payment of the Environmental Fee and picture ID.
4. Check the five 5-gallon or twenty-five 1-gallon liquid-container allowance and the separate 220-pound HHW weight cap.
5. Keep contents in original containers. The city says leaking containers should be handled using a leak-proof or lined cardboard box. Do not mix products in the same container or bag.
6. Put the items in a box in the trunk or truck bed. A technician unloads the HHW; follow the on-site directions and ask about container return if needed.

These packing and unloading instructions are from the city’s current HHW guidelines. The page says containers may be returned on request, but non-approved containers will not be returned. If the packaging is deteriorating or the instruction does not clearly fit your item, get staff advice before transporting it.

Fees, questions and avoiding an unsuccessful trip

The official monthly and quarterly event pages label those events free. For Culebra visit charges, any visit allowance and appointment arrangements, contact the Solid Waste Management Department at 3-1-1 or 210-207-6000. Check these questions for your intended visit rather than extending event pricing to another service.

San Antonio’s rates page explains the Environmental Fee within household city-service billing. That helps you understand why the HHW document check refers to a fee on the CPS Energy bill. It does not replace the requirement to bring a recent bill showing payment and picture ID. City billing and rates; HHW document rule.

For a difficult item, give customer service the material name, amount, condition, household or business origin and the location you want to use. Ask about acceptance, packing, documents and the planned day together. The published numbers are 3-1-1 and 210-207-6000. Department contact details.

Consider whether usable possessions can be kept or passed on before scheduling disposal, but ask the recipient what it accepts. Do not assume a charity takes paint or chemicals. For anything still needing HHW handling, keep the city’s confirmed route in your plan rather than leaving it with an unrelated donation load.
