This guide empowers Houston residents, from homeowners to renters, with clear, actionable information to confidently participate in the city’s curbside recycling program.

By following these local guidelines, you contribute to maximizing resource recovery and minimizing waste sent to landfills, making Houston a cleaner, greener place for everyone.

What Goes In: Acceptable Items for Your Green Bin

The City of Houston’s curbside recycling program focuses on collecting specific, high-value materials. Here’s a detailed list of what you can place in your green recycling cart:

Plastics

Only rigid plastic containers marked with the #1 or #2 symbol on the bottom are accepted. These typically include:

  • #1 Plastics (PET/PETE): Water bottles, soda bottles, and some food containers (e.g., peanut butter jars, salad dressing bottles).
  • #2 Plastics (HDPE): Milk jugs, detergent bottles, shampoo bottles, and some cleaning product containers.

Ensure these are empty, clean, and dry before placing them in the bin.

Paper and Cardboard

Most paper and cardboard products are accepted, provided they are clean and dry:

  • Mixed Paper: Newspapers, magazines, junk mail, envelopes (windows are okay), catalogs, phone books, paperback books, paperboard (e.g., cereal boxes, tissue boxes – remove plastic liners).
  • Corrugated Cardboard: Shipping boxes, pizza boxes (clean, without grease stains). Flatten all cardboard boxes to save space.
  • Shredded Paper: Must be placed inside a paper bag (e.g., a brown paper grocery bag) to prevent it from scattering during collection and sorting.

Metals

Two primary types of metal containers are accepted:

  • Aluminum Cans: Soda cans, beer cans, aluminum foil (clean and rolled into a ball). Empty and rinse thoroughly.
  • Steel/Tin Cans: Food cans (e.g., soup cans, vegetable cans), pet food cans. Empty and rinse thoroughly. Labels do not need to be removed.

What Stays Out: Common Unacceptable Items and Why

Placing non-recyclable items in your green bin, often called “wishcycling,” can contaminate an entire load, leading to it being landfilled. Here are common items NOT accepted in Houston’s curbside program and the reasons for their exclusion:

  • Glass: Glass breaks into small shards that contaminate other recyclables and pose a safety hazard to workers. While it’s recyclable, it’s not accepted curbside in Houston.
  • Plastic Bags and Plastic Film: These items jam sorting machinery at material recovery facilities. This includes grocery bags, dry cleaning bags, newspaper bags, and plastic film packaging. They require specialized drop-off locations.
  • Styrofoam (Polystyrene): This material is difficult to process, takes up too much space, and breaks into small pieces, contaminating other materials.
  • Electronics (E-waste): Computers, TVs, phones, and other electronics contain hazardous materials and should never be put in the curbside bin. They require special e-waste recycling events or drop-off centers.
  • Food Waste and Food-Soiled Items: Any items with significant food residue (e.g., greasy pizza boxes, food-stained paper plates) cannot be recycled as they contaminate paper and cardboard.
  • Clothing/Textiles: These items wrap around machinery and require textile recycling programs.
  • Batteries: Batteries, especially lithium-ion, pose fire risks. They must be recycled separately at designated drop-off points.
  • Hazardous Waste: Paint, chemicals, motor oil, and other household hazardous waste (HHW) are strictly prohibited and require specific disposal events or facilities.

Preparing Your Recyclables: Clean, Dry, and Loose is Key

Proper preparation is just as important as knowing what to recycle. Following these simple steps ensures your recyclables can be processed efficiently:

  • Clean: All containers (plastics, cans) must be empty and rinsed to remove food residue. This prevents odors, pests, and contamination of other materials.
  • Dry: Ensure items are relatively dry to prevent mold and mildew, especially for paper and cardboard products.
  • Loose: Place all acceptable items directly into your green cart. Never bag your recyclables in plastic bags. Loose items can be sorted by machinery, whereas bagged items are typically sent to the landfill because workers cannot safely or efficiently open them for sorting.
  • Flatten Cardboard: Break down and flatten all cardboard boxes to maximize space in your bin and the collection truck.

Beyond the Bin: Alternative Disposal for Unaccepted Items

Just because an item isn’t accepted in your curbside bin doesn’t mean it can’t be recycled or disposed of responsibly. Houston offers several options for these materials:

  • Household Hazardous Waste (HHW) and Electronics: The City of Houston Solid Waste Management Department operates Neighborhood Depository and Recycling Centers that accept HHW and electronics. Check the official city website for locations, operating hours, and accepted materials.
  • Plastic Film and Bags: Many local grocery stores (e.g., H-E-B, Kroger, Walmart) have collection bins for plastic bags and plastic film. Look for these designated drop-off points at store entrances.
  • Glass: Some private recycling centers or specialized collection events in Houston may accept glass. It is advisable to verify current local options, as these can change.
  • Textiles: Look for local textile recycling programs or donation centers for clothing and fabrics in good condition.

For the most current information on specialized recycling programs, always consult the City of Houston Solid Waste Management Department’s website or contact 311 Houston.

Quick Reference: Houston Curbside Recycling Decision Checklist

Before tossing an item into your green bin, run through this quick checklist:

  • Is this item explicitly listed as an accepted material: plastic #1/#2, paper, cardboard, aluminum, or steel?
  • Is the item completely empty, clean, and dry with no food residue or liquid remaining?
  • Is the item loose in the bin, not contained within a plastic bag or any other container?
  • Does this item have a recycling symbol, and if so, is it specifically #1 or #2 plastic?
  • Is it glass, Styrofoam, or a plastic bag? If yes, it does NOT go into the Houston curbside recycling bin.

Common Recycling Mistakes in Houston

Avoid these frequent errors to ensure your recycling efforts are effective:

  • “Wishcycling”: Placing items like glass, plastic bags, or unmarked plastics hoping they are recyclable, which contaminates the entire load.
  • Not cleaning containers: Leaving food residue or liquids in jars, cans, or bottles, which contaminates other recyclables and can attract pests.
  • Bagging recyclables: Putting accepted items inside plastic bags, which jams sorting machinery and causes the entire bag’s contents to be landfilled.
  • Recycling shredded paper loosely: Shredded paper must be placed in a paper bag before being put in the green cart; loose shredded paper falls through sorting screens and becomes trash.
  • Ignoring plastic numbers: Assuming all plastics are recyclable, rather than specifically checking for #1 and #2 symbols required by Houston’s program.

Frequently Asked Questions (FAQs)

Q: Do I need to remove labels from plastic bottles or cans?

A: No, you do not need to remove labels from plastic bottles, jars, or metal cans. The recycling process accounts for these. Just ensure the containers are clean and empty.

Q: Can I recycle plastic produce containers (e.g., strawberry cartons)?

A: Many plastic produce containers are made from plastics #1 (PET) or #6 (PS, Styrofoam). Only containers marked #1 are accepted in Houston’s curbside program. If it’s #6 or unmarked, it should go in the trash. Always check the recycling symbol on the container.

Q: What should I do with oversized cardboard boxes?

A: Oversized cardboard boxes should be broken down and flattened. If they are too large to fit in your green cart, you may need to take them to a Neighborhood Depository and Recycling Center, or cut them into smaller pieces that fit within the cart with the lid closed.
