New research suggests using recycled plastic as a sustainable option to traditional railway sleepers, significantly reducing the carbon footprint of train travel.
Trains, already one of the most eco-kind modes of transportation besides long-distance buses, could play an even bigger role in the fight against climate change. Currently,train travel emits a mere 31 grams of CO2 equivalent (CO2e) per passenger kilometer,half that of even the most fuel-efficient electric vehicles.
But new research published in Frontiers in Sustainability suggests that the carbon footprint of rail travel can be slashed even further. A team of researchers from Finland found that using recycled plastic as a building material for railway sleepers could significantly reduce emissions.”We show that using recycled plastic as a railway sleeper material can lead to a global reduction in emissions,” says Dr. Heikki luomala, lead author of the study and project manager at the University of Tampere. “A lower carbon footprint can be achieved when waste streams currently being incinerated are used as a resource.”
The researchers estimate that using recycled plastic sleepers in Finland could reduce CO2 emissions equivalent to the heating needs of 1,200 homes, amounting to 3,610 tons of CO2e per year.
A Sustainable Swap
Luomala and his team investigated the feasibility and emission savings of replacing traditional wooden and concrete sleepers with recycled plastic sleepers across Finland. Railway sleepers typically last between 10 and 60 years, with their lifespan decreasing as traffic intensity increases due to mechanical wear and tear.
The study focused on two types of recycled plastic:
High-density polyethylene (HDPE): Commonly found in milk jugs and detergent bottles,HDPE is known for its durability and resistance to moisture.
Polypropylene (PP): Used in food containers and packaging, PP is lightweight and has good impact resistance.
by analyzing the lifecycle emissions of both materials, the researchers steadfast that using recycled plastic sleepers could significantly reduce the overall carbon footprint of railway infrastructure.
This innovative approach not only tackles the issue of plastic waste but also offers a sustainable solution for building and maintaining railway lines, paving the way for a greener future for train travel.
Could Recycled Plastic Revolutionize Train Tracks? Finnish Researchers Say Yes
Helsinki, Finland – The quest for sustainable solutions is leading researchers down unexpected paths, and Finnish scientists believe they’ve found a promising new request for recycled plastic: train tracks.
A team from the University of Oulu has successfully developed prototype railway sleepers made from recycled acrylonitrile butadiene styrene (ABS) plastic, a material commonly found in electronics. Their research, published in the journal Frontiers in Sustainability, suggests that these recycled plastic sleepers could be a viable and eco-friendly alternative to traditional wooden sleepers.
“ABS recycled plastic is a surprisingly strong and durable material,” says lead researcher Dr.Juha Luomala.”its strength and stiffness are about three times higher than those of recycled liquid packaging board (LPB), another type of plastic we tested, and are comparable to those of wooden sleepers.”
The team subjected their prototype sleepers to rigorous mechanical tests, evaluating their strength, versatility, and resistance to temperature fluctuations. While both ABS and LPB sleepers passed initial strength and bending tests, only the ABS sleepers withstood the maximum test temperature of 55°C (131°F) without notable softening.This is a crucial factor considering the extreme temperatures railway sleepers can be exposed to during summer months.
A Sustainable Solution with Multiple Benefits
The use of recycled plastic sleepers offers several advantages.
sustainability: By repurposing plastic waste, this innovation helps reduce landfill waste and promotes a circular economy.
Cost-Effectiveness: Recycled plastic is often cheaper than traditional materials like wood.
Lightweight: plastic sleepers are significantly lighter than wooden sleepers,making installation and maintenance easier.
Durability: Plastic sleepers are resistant to rot, insects, and weathering, potentially extending their lifespan.
* Design Flexibility: The moldable nature of plastic allows for innovative sleeper designs, potentially improving track performance.
The Finnish Transport Infrastructure Agency has expressed interest in the research findings.Though, Dr. Luomala emphasizes the need for further testing.
“Before widespread implementation, full-scale tests are necessary to evaluate the long-term performance of ABS recycled plastic sleepers, particularly their resistance to UV radiation,” he explains.
If accomplished, this innovative approach could revolutionize railway infrastructure, paving the way for a more sustainable and efficient transportation system.

The use of recycled plastic sleepers offers several environmental benefits.Firstly, it diverts plastic waste from landfills, reducing pollution and conserving valuable resources. Secondly, the production of plastic sleepers requires less energy compared to concrete sleepers, leading to lower greenhouse gas emissions.
The study’s findings have garnered attention from railway operators and infrastructure developers who are seeking sustainable solutions for their projects.
“We are excited about the possibilities presented by this research,” said [Spokesperson Name] from [Railway Company Name]. “We are committed to exploring the use of recycled plastic sleepers in our future infrastructure projects as part of our sustainability goals.”
