Many of us want to do our part for the environment by recycling, but sometimes our good intentions lead to unintended consequences. This is particularly true when it comes to recycling contamination.
Recycling contamination can have impacts that extend beyond just one single item. In fact, it can deem an entire recycling truck as non-recyclable.
It occurs when items that cannot be recycled are mixed in with recyclable materials. This can include anything from food waste and coffee cups to greasy pizza boxes and broken glass. When these non-recyclable items end up in the recycling stream, they not only foul other recyclables but also pose challenges for recycling facilities.
hidden Consequences of a Contaminated Recycling Bin
- Increased Sorting Costs: Sorting contaminated materials at a recycling facility is time consuming and drives up the costs of recycling. Many facilities will pass this added cost onto the customer responsible for the contamination.
- Reduced Quality of the Recyclables: Contamination compromises the quality of other recyclables in the bin or truck.
- Environmental Consequences: Recycling is a key environmental activity to extend the lifetime of our materials and avoid the use to disposal cycle. When a batch of recyclables is contaminated, it must be sent to a waste to energy plant, thus undermining the essence of recycling efforts.
- Higher Landfill Overflow: This practice of contamination accelerates the filling of landfill sites, many of which are already nearing capacity. Overflowing landfills contribute to environmental problems like groundwater pollution and increased methane emissions.
To effectively combat recycling contamination, several proactive steps can be implemented. First and foremost, taking the time to educate ourselves and others about what can and cannot be recycled lays a strong foundation for reducing contamination. Additionally, being mindful when disposing of items ensures that only appropriate materials end up in the recycling stream. Ultimately, every small effort matters because every item placed in the recycling bin plays a role in creating cleaner, more sustainable communities.
how to combat Recycling Contamination
Preventing recycling contamination starts with awareness and simple changes in behavior. Here are some actionable tips:
Familiarize Yourself with Ireland’s Recycling List
Ireland follows a national recycling list for household items, but not everything can go into the green bin. Items like plastic bottles, cardboard, and clean paper are accepted, while soft plastics like wrappers often require separate disposal.
Actionable Tip: Visit mywaste.ie to access Ireland’s official recycling guidelines and learn what materials are accepted in your local area.
Recycle Soft Plastics Correctly
Since September 2021, Ireland allows soft plastics to be placed in recycling bins as long as they are clean and dry. Items like bread bags, plastic wraps, and crisp packets are now recyclable.
Actionable Tip: Wash and dry soft plastics before placing them in your green bin to ensure they don’t contaminate other recyclables.
Avoid Hazardous Waste in Bins
Hazardous items like paint, oil, and batteries require special handling and should never go into green or black bins. Ireland provides specific waste disposal services for these materials.
Actionable Tip: Check with your local authority or Civic Amenity Centre for hazardous waste collection events or permanent drop-off locations.
