Designing for Circularity with SpunMelt PLA – Sustainability Without Compromise
In air filtration systems, SpunMelt multilayer structures are commonly used, where spunbond layers provide mechanical strength and meltblown layers deliver fine filtration performance. Traditionally, this functionality comes with a trade-off: the use of different materials for different layers, making the structure difficult to recycle.
What if we could deliver the same high performance using just one material
without compromising recyclability, and with a significantly carbon footprint reduction?
Now we can. At TotalEnergies Corbion, we're proud to introduce a mono-material PLA solution using:
- Luminy® L130 for the spunbond layers
- Newly introduced Luminy® L040 for the meltblown layer
Together, they enable:
- High-performance SpunMelt nonwovens for air filtration
- 100% biobased, industrially compostable, and recyclable structures
- Up to 85% carbon footprint reduction compared to conventional plastics — even carbon-neutral or negative when using Luminy® rPLA
This is design for circularity in action — transforming complex, multi-material systems into recyclable mono-material solutions that deliver on both performance and sustainability.
