Should you remove plastic bottle lids before recycling or leave them on?
If you are eager to start recycling correctly, you are on the right track. Believe it or not, there are some dos and don’ts to recycling that many well-intentioned people overlook. Read on to discover if leaving the lids of plastic bottles on when recycling them is a do or a don’t.
Lids Are Made of Different Type of Plastic
When it comes to recycling plastic bottle lids, the answer is clear: remove them before you recycle! Leaving lids on can present several issues for the recycling process. Most importantly, bottle lids are made of a different type of plastic than the bottles themselves. This can disrupt the sorting process at recycling plants and hinder their ability to separate materials correctly.
Additionally, when bottle lids are left on, it can also cause the bottles to jam in plant machinery, leading to costly damage and delays. Lastly, leaving lids on can lead to fillers that contaminate a batch of recycled material; this is especially true for plastic-metal lids which can contain traces of metal like aluminum or steel.
For these reasons, it is always best to remove plastic bottle lids before recycling, regardless of the type of lid or material used. Removing lids ensures that your recycling makes it through the sorting and processing processes without any issues. As a result, the recycled materials can be safely reused in new products, which benefits both the environment and people.
In conclusion, it is important to remember that removing plastic bottle lids before recycling is essential for successful reprocessing of materials. Removing lids helps ensure that your recycling makes it through the sorting and processing stages with no problems and can be safely reused in new products.
Create Additional Contamination In The Recycling Stream
The answer to this question depends on the type of plastic bottle lid. Generally speaking, it is best to remove all plastic lids before recycling them. This is because some plastics have different melting points than other plastics and could cause problems during the recycling process.
Additionally, leaving lids on can also create additional contamination in the recycling stream which could lead to contaminated materials being produced and sold. Therefore, for the most effective and efficient recycling process, it is best to remove plastic bottle lids before recycling them.
Different Type of Plastic, Different Way of Recycling
The main reason behind having to separate the bottle from the cap is due to the manner in which different types of plastics are recycled.
Most disposable pop and water bottles are polyethylene terephthalate (PET or PETE). While the caps for these bottles are often made of either plastic (High-density polyethylene or HDPE),(Polypropylene or PP), or (Low-density polyethylene or LDPE).
Different types of plastics are recycled differently because they have unique chemical and physical properties that require different recycling processes. Pellets from distinct plastics are made to create distinct items and cannot be mixed.
Although many modern recycling facilities do have a system to take the lid off of the bottle, it is still generally recommended to remove the cap before recycling since it is not a foolproof system and sometimes the lids are not recycled at the same facility.
Small Things May Jam or Malfunction Machinery
Because they are frequently too small to be identified by recycling machinery, plastic bottle lids must be removed before recycling for a special reason. Smaller things like bottle caps, which can fall through the sorting screens, can contaminate other materials whereas bigger plastics can be mechanically separated. When lids are left on, they might pose a risk to the recycling process and jam or malfunction machinery.
Furthermore, because lids are made of a different kind of plastic than the bottles themselves, the recycled material may become contaminated. Our recycling efforts can be made more efficient and long-lasting if the lids are taken off and disposed of separately.
