J&B Recycling Knowledge

Pizza is one of the UK's favourite takeaways, but when it comes to disposing of the box afterwards, many people are unsure whether it belongs in the recycling bin or the general waste.

The good news is that most pizza boxes can be recycled. However, there are some important exceptions that can affect whether the material can be successfully processed and turned into new products.

Why Pizza Boxes Can Be Recycled

Pizza boxes are typically made from cardboard, which is a widely recycled material. When clean and dry, cardboard can be collected, sorted and processed into new paper and cardboard products.

At J&B Recycling, cardboard is separated and sorted before being sent on for reprocessing, helping to keep valuable materials in circulation and reducing the need for virgin resources.

The Problem With Grease and Food Residue

One of the biggest challenges with pizza boxes is contamination from food and grease.

Recycling relies on materials being clean and of good quality. When cardboard becomes heavily saturated with oil, cheese or leftover food, it can affect the recycling process and reduce the quality of the recycled material.

While small amounts of grease are generally not an issue, heavily soiled sections of the box may not be suitable for recycling.

What Should You Do With Your Pizza Box?

Before placing a pizza box in your recycling bin, follow these simple steps:

• Remove any leftover food, crusts or napkins.
• Separate clean sections from heavily greasy sections where possible.
• Flatten the box to save space in your recycling bin.
• Place clean cardboard into your recycling bin.

If the bottom of the box is heavily contaminated with grease but the lid is clean, consider tearing off the clean lid and recycling that portion separately.

What About Pizza Box Inserts?

Many takeaway pizza boxes contain additional materials that should be removed before recycling, including:

• Plastic pizza savers (the small plastic stand in the centre)
• Plastic liners
• Sachets and condiment packets
• Disposable cutlery

These items should be disposed of separately according to your local recycling guidance.

Why Reducing Contamination Matters

Contamination is one of the biggest challenges facing the recycling industry. When food waste enters recycling streams, it can affect otherwise recyclable materials and increase the amount of waste that has to be removed during the sorting process.

At our Material Recovery Facility (MRF), our teams carry out quality control checks to remove contamination and ensure materials meet the standards required by reprocessors. However, the cleaner materials are when they arrive, the more efficiently they can be recycled.

The Bottom Line

Yes, pizza boxes can usually be recycled, provided they are free from significant food contamination.

A quick check before putting your box in the recycling bin can help ensure more cardboard is successfully recycled and turned into new products.

If in doubt, remove any heavily soiled sections and recycle the clean cardboard where possible.
