Recycling Cardboard Boxes with Tape in the UK (2026): What Businesses Need to Know

Cardboard boxes are one of the most common types of waste produced by businesses. From deliveries and packaging to e-commerce shipping and office supplies, many workplaces handle dozens or even hundreds of boxes every week.

But when it comes time to recycle them,there’s one question we get all the time: what should you do about the tape?

This was the question asked by one of our followers last month on linkedIn and we’re finally dedicating a blog to answer this question in depth.

Many cardboard boxes arrive sealed with plastic packaging tape, labels, or adhesive strips. Business owners and households often assume that this makes the cardboard unrecyclable, or that every piece of tape must be removed before recycling.

The reality is a little more nuanced. In this blog, we’ll explain whether cardboard boxes with tape can be recycled in the UK, how the 2026 recycling rules affect businesses, and the best practices for recycling cardboard properly.

 

Can You Recycle Cardboard Boxes with Tape on Them?

In most cases, yes, cardboard boxes with small amounts of tape can still be recycled.

During the recycling process, cardboard is broken down into fibres and turned into pulp. Non-paper materials like tape, labels, and adhesives are typically filtered out during processing.

However, recycling facilities still prefer cardboard to be as clean and uncontaminated as possible. Large amounts of plastic tape, packaging materials left inside boxes, or greasy residue can make recycling more difficult and may lead to loads being rejected.

For that reason, most waste providers recommend removing as much tape as is reasonably possible, especially in commercial recycling systems where large volumes are processed in one go.

 

Why This Matters for Businesses

Cardboard is one of the most valuable recyclable materials produced by businesses. Warehouses, offices, retailers, and restaurants all generate large quantities through deliveries and packaging.

Importantly, cardboard can be recycled five or six times, and recycling it uses significantly less energy than producing new cardboard from raw materials.

This makes recycling important for everyone but businesses especially, face additional responsibilities compared to households.

Since March 31, 2025, workplace recycling rules in England require businesses to separate recyclable materials, including paper and cardboard, from other waste streams.

This means that:

• Cardboard must be kept separate from general waste 
• Businesses must take reasonable steps to prevent contamination 
• Waste collectors must ensure separated recyclables are actually recycled 

Failure to follow these rules can result in compliance notices or financial penalties.

For companies that produce large volumes of packaging waste, keeping cardboard clean and properly sorted is essential.

 

The Common Mistakes Businesses Make

Even businesses that are committed to recycling often make small mistakes that reduce the quality of their cardboard waste.

Some of the most common issues include:

Leaving boxes filled with packaging materials
Plastic wrap, foam, or polystyrene left inside boxes can contaminate recycling loads.

Excess packaging tape
A small amount of tape is usually acceptable, but boxes heavily covered in plastic tape can cause problems.

Food or liquid contamination
Cardboard that is greasy, wet, or covered in food residue cannot usually be recycled.

Not flattening boxes
Unflattened boxes take up valuable space in bins and collections, increasing costs and reducing efficiency.

These issues can lead to contamination, which sometimes causes entire batches of cardboard to be rejected.

 

Best Practices for Recycling Cardboard Boxes with Tape

If your business handles a large amount of cardboard packaging, following a few simple steps can help ensure it stays recyclable.

1. Remove Excess Tape Where Possible

You don’t need to spend time peeling off every small strip of tape. However, removing large pieces of plastic tape improves recycling quality.

2. Flatten Boxes Before Disposal

Flattening cardboard saves space in bins and makes collection easier for recycling providers.

3. Empty All Packaging Materials

Make sure boxes are free of plastic fillers, foam inserts, and packing peanuts.

4. Keep Cardboard Clean and Dry

Wet, greasy, or food-stained cardboard is difficult to recycle and may have to be sent to landfill or energy recovery instead.

5. Use a Dedicated Cardboard Bin

Separating cardboard from other recyclables reduces contamination and improves recycling rates.
