The UK has made significant strides in waste management, with the national recycling rate climbing toward the 2035 goal of 65 per cent. However, millions of tonnes of potentially recyclable material still end up in landfill or incineration every year.
Recent studies suggest that nearly a quarter of UK households still feel they lack the specific knowledge to bin items correctly. With the 2026 launch of the government’s Simpler Recycling scheme, the rules are becoming more consistent, but habits still need to catch up.
At Bywaters, London’s leading waste management provider, we believe that education is the best tool for sustainability. Here are five common mistakes to watch out for.
The Contamination Trap
One of the biggest hurdles in UK recycling is “wishcycling,” which is the act of putting something in the recycling bin hoping it can be recycled when it is actually contaminated.
Food residue is the primary culprit. If a pizza box is soaked in grease or a plastic tub is smeared with sauce, it can ruin an entire batch of clean paper or cardboard. At our Lea Riverside Materials Recovery Facility (MRF), we see how a single unwashed item can lead to high-quality resources being diverted to energy-from-waste instead of being repurposed. The rule is simple: if you can eat off it, you can recycle it. Always rinse your containers.
The Black Plastic Myth
For years, black plastic was the “villain” of the recycling bin because older Near-Infrared (NIR) sensors could not detect the carbon black pigment against conveyor belts.
In 2026, technology has improved, and many UK facilities, including Bywaters, have upgraded their optical sorting to better identify dark polymers. However, some local authorities still struggle with this material. To be safe, try to choose clear or light-coloured plastic packaging, as these have a much higher “circular value” and can be recycled into a wider variety of new products.
Forgetting the ‘Reuse’ in the Hierarchy
While recycling is vital, it is actually the third step in the waste hierarchy. Reducing and reusing come first.
Plastic bags and “flexible” plastics are often found clogging up sorting machinery at MRFs. While many supermarkets now offer take-back schemes for these films, the most sustainable choice is to reuse what you already have. If you can repurpose an item yourself, you are directly reducing the carbon footprint of the manufacturing process.
Not All Glass is Equal
A common mistake is assuming that any glass item belongs in the recycling bin. While glass bottles and jars are 100 per cent recyclable, other items like lightbulbs, Pyrex dishware and drinking glasses are not.
These items are made of different glass types with higher melting points. If a heat-resistant Pyrex dish ends up in a furnace with standard glass bottles, it causes “stones” or structural weaknesses in the new glass. Always use specialist recycling points for lightbulbs and non-container glass to avoid contaminating the stream.
Nested and Multi-Material Items
To manage the waste of an entire nation, items move through our high-speed machinery in under a second. This means that “nested” items, such as a plastic yogurt pot tucked inside a tin can, cannot be separated by our automated sensors.
Similarly, items made of mixed materials, like certain children’s toys or musical instruments, should be taken apart before they are binned. If an item is composed of glued-together plastic and metal, it is likely to be rejected. By separating these components yourself, you ensure the machinery can accurately identify the Seventh Resource.
