7 Takeout Containers You Can Never Recycle No Matter What

Ordering takeout is convenient and satisfying, but it often leaves behind a pile of packaging that is not as eco-friendly as it looks. While some containers appear recyclable, many are made from mixed materials or contaminated by food waste, making them impossible to process correctly. Knowing which ones to keep out of your recycling bin can help reduce contamination and protect the environment. Here are seven common takeout containers that you should never recycle, no matter how tempting it may be.

1. Styrofoam Containers

Styrofoam, also called expanded polystyrene, is one of the least recyclable materials used for takeout packaging. It is lightweight, affordable, and good at keeping food warm, but it breaks into small pieces that pollute waterways and harm wildlife. Most recycling facilities do not accept Styrofoam because it is difficult and expensive to clean, transport, and reuse. Even if the container has a recycling symbol, that does not mean your city can process it. If possible, reuse it once before placing it in the trash to reduce waste.

2. Black Plastic Containers

Black plastic containers are commonly used for restaurant meals, but they are rarely recyclable. Recycling plants use optical scanners to identify plastics by color, and the black pigment absorbs light instead of reflecting it, preventing sorting machines from detecting it. This means most black plastics are rejected and end up in landfills. Even if they have a recycling logo, that does not guarantee they will be accepted. When ordering food, try to choose clear or light-colored containers that recycling facilities can recognize and process properly.

3. Greasy Pizza Boxes

Cardboard pizza boxes are deceptive because they look recyclable at first glance. The problem is that oil and cheese residue soak into the cardboard, contaminating entire recycling batches. Once grease mixes with paper fibers, the cardboard can no longer be turned into new paper products. To reduce waste, tear off and recycle the clean top portion, and compost the greasy bottom if your city allows food-soiled cardboard. Otherwise, the entire box should go into the trash. Choosing reusable pizza boxes or compostable liners is a greener alternative.

4. Plastic-Coated Paper Cups and Boxes

Many paper containers for coffee, noodles, and soup are lined with a thin layer of plastic or polyethylene to prevent leaks. While that lining keeps liquids from soaking through, it also makes the container nearly impossible to recycle. The mixture of paper and plastic requires specialized equipment that most paper mills do not have. Even compostable cups are only effective in cities that have industrial composting facilities. If those services are unavailable, these containers will end up in landfills. Bringing your own reusable cup is a better solution.

5. Aluminum Containers with Plastic Lids

Aluminum containers may seem recyclable, but they often come with plastic or paper lids that make things complicated. When two materials are glued or crimped together, they cannot be easily separated during recycling. Leftover grease or food residue makes the problem worse, causing contamination. If the aluminum tray is clean and the lid can be removed, the tray itself can go in the recycling bin, while the lid should be discarded. Always check local recycling guidelines to make sure your facility accepts this type of container.

6. Compostable Containers Labeled “Biodegradable”

Many takeout containers labeled as biodegradable or compostable sound environmentally friendly, but most cannot break down in a regular landfill. These containers are usually made from bioplastics that need high heat and specific industrial composting conditions to decompose. Since most cities do not have these facilities, the containers often end up in the trash. They also cannot be recycled with regular plastics. To make a real impact, look for items certified for composting by trusted organizations or bring your own reusable containers for takeout.

7. Wax-Coated Paper Containers

Wax-coated paper containers, such as those used for Chinese food, popcorn, or ice cream, are moisture-resistant but unsuitable for recycling. The wax coating prevents the paper from breaking down properly and can clog recycling machinery. Even containers with plant-based wax coatings are rejected by most recycling centers. Unless your area has specialized facilities, these containers should be disposed of in the trash. To reduce waste, you can reuse them for dry snacks or crafts before discarding them responsibly.
