Frozen food boxes, also known as wet-strength paperboard, may seem like a simple paper product to recycle. However, the reality is a bit more complicated. These boxes are made with a combination of paperboard and polyethylene plastic, which helps maintain the structure of the container in cold temperatures and prevents it from getting soggy. This added plastic makes recycling frozen food boxes a challenge in some municipalities.
The plastic in frozen food boxes is not easily separated from the paperboard, making it difficult for some recycling facilities to accept them. While some cities like Phoenix and San Diego have found ways to recycle these boxes, others like Portland, Oregon do not accept them in their recycling streams.
The decision to accept frozen food boxes for recycling depends on various factors, including the capabilities of the recycling facility and the demand for recycled materials. For example, some paper mills may not be interested in using paper that contains polyethylene, while others can adjust their processes to accommodate these materials.
Cities like Phoenix and San Diego have found success in recycling frozen food boxes by identifying a recycling market for them and ensuring that the paper waste stream is not contaminated by the plastic in the boxes. By allowing residents to put these boxes in their curbside bins, these cities have simplified the recycling process and achieved cleaner recycling streams.
It’s important for residents to check their local regulations before putting frozen food boxes in their recycling bins. Some cities may sort these boxes at their materials recovery facilities, while others may not accept them at all. By understanding the recycling guidelines in their area, residents can help ensure that their recycling efforts are effective and environmentally friendly.
