Why We Should Separate Liquids from Recyclables

A Simple Step That Improves Recycling Rates

Effective recycling relies on clean, uncontaminated waste streams. Across workplaces, transport hubs, retail environments, educational facilities, and public spaces, one common issue can thwart recycling efforts: liquids being disposed of alongside recyclable materials.

According to the Environmental Protection Agency (EPA), Ireland generates more than 14 million tonnes of waste each year across households, workplaces, construction activity and industry, making effective waste segregation critical to maintaining recycling quality. Ireland generated approximately 3.1 million tonnes of municipal waste in 2024, of which 43% was recycled, highlighting the need to improve recycling performance and material quality. Contamination remains a significant challenge. Research cited by Repak, based on EPA data, estimates that 127,000 tonnes of material are incorrectly placed in recycling bins each year, representing approximately one 25% of materials presented for recycling. In addition, a 2025 MyWaste survey found that 33% of people admitted knowingly placing incorrect items into their brown bin, demonstrating how contamination and poor segregation continue to affect Ireland's waste management system.

For organisations striving to improve sustainability performance and achieve waste management targets, separating liquids from recyclables is relatively simple but highly effective.

The Impact of Liquid Contamination

When liquids enter dry mixed recycling streams, they can create various challenges throughout the waste management process

Reduced Recycling Quality

Paper, cardboard, and other recyclable materials can become saturated when mixed with drinks, water, or food liquids. Once contaminated, these materials may no longer be suitable for recycling and can instead be diverted to energy recovery sites or landfill.

Increased Processing Costs

According to Repak, contaminated materials such as food-soiled packaging, wet paper, and containers containing liquids can lead to the rejection of entire recycling loads, reducing recovery rates and increasing waste management costs.

Health and Hygiene Concerns

Liquids left in waste and recycling containers can create unpleasant odours, encourage bacterial growth, and attract vermin and pests. This can negatively impact workplace hygiene and the user experience in public environments.

Operational Challenges

Leaking containers can create spillages inside recycling bins, collection vehicles, and storage areas. This can increase cleaning requirements and contribute to maintenance costs for facilities management teams.

Why Organisations Should Encourage Liquid Separation

For businesses and organisations in the public sector, improving recycling rates is about more than just environmental responsibility. It can also support operational efficiency, compliance objectives, and company sustainability goals.

Encouraging people to empty bottles and containers before disposal can help:

Improve the quality of recyclable materials.
Reduce contamination rates.
Increase recycling rates.
Support waste reduction targets.
Enhance cleanliness and hygiene standards.
Demonstrate commitment to environmental best practice.

As sustainability reporting and environmental accountability become increasingly important, even small improvements in waste segregation can contribute to larger and wider environmental initiatives.

Practical Ways to Correctly Recycle Liquids

Poor waste segregation and confusion about what can and cannot be recycled remain major contributors to contamination. Research conducted for MyWaste Ireland found that 26% of people cited confusion about accepted materials as a reason for placing incorrect items in recycling streams, while 38% said they sometimes dispose of items incorrectly when in a hurry.

Many recyclable containers still contain small amounts of liquid when they reach recycling stations and disposal points. Providing clear guidance and appropriate solutions, such as integrated liquid reservoirs, can help people easily and correctly dispose of any unwanted liquids, whilst an integrated drip tray can help capture any residual liquids.

Empty Bottles Before Recycling

Encourage staff, visitors, customers, and members of the public to completely empty drinks containers into any available reservoirs before placing them into recycling bins.

Provide Dedicated Liquid Disposal Points

Create dedicated liquid disposal points by installing recycling stations with integrated liquid reservoirs. This will enable people to simply pour away leftover liquids before disposing of any bottles, cans, and cups, maintaining cleaner recycling streams and reducing contamination in the process.

Create Clear Recycling Stations

Waste management systems are most effective when the people using them can quickly and immediately understand how to correctly dispose of things. Signage, colour coding, and clear labelling, such as a distinct visual graphic for a reservoir side pod, can improve recycling practices and reduce disposal errors and cross-contamination.

Position Liquid Disposal Solutions Strategically

Locations such as office buildings, university campuses, school grounds, transport hubs, shopping centres, stadiums, and leisure facilities will often generate high volumes of drinks containers. Installing recycling stations with dedicated liquid disposal reservoirs near shops, kiosks or fast-food restaurants, as well as in canteens, break areas, shared kitchens and even meeting rooms and hallways leading to gathering spots can help encourage correct waste segregation right at the point of disposal.

Supporting Better Recycling Habits

Creating and maintaining clean, uncontaminated recycling streams starts with providing users with a simple and convenient way to separate liquids from recyclable containers. When organisations combine clear waste segregation practices with dedicated liquid collection solutions, they can reduce contamination, improve recycling efficiency, and support their wider sustainability objectives.

As recycling targets continue to increase across Europe, ensuring liquids are removed before recyclables enter the waste stream is an easy and likewise practical step that can make a measurable difference to environmental performance.
