When it was first produced, polylactic acid cost about $200 to make one pound. Thanks to innovations in manufacturing processes, it costs less than $1 per pound to manufacture today. Because it’s no longer cost-prohibitive, polylactic acid has the potential for massive adoption.
The most common uses include:
- 3D printing material filament
- Medical implants and devices
- Fibers (carpet, clothing)
- Packaging
In all these applications, the polylactic acid alternatives present clear advantages over traditional materials.
For example, in 3D printers, PLA filaments are one of the most popular choices. They have a lower melting point than other filament options, making them easier and safer to use. 3D printing PLA filament emits lactide, which is considered a non-toxic fume. So, unlike the filament alternatives, it prints without emitting any harmful toxins.
It also presents some clear advantages in the medical field. It’s favored because of its biocompatibility and safe degradation as polylactic acid products degrade into lactic acid. Our bodies naturally produce lactic acid, so it’s a compatible compound. Because of this, PLA is frequently used in drug delivery systems, medical implants, and tissue engineering.
In the fiber and textile world, advocates aim to replace nonrenewable polyesters with PLA fiber. Fabrics and textiles made with PLA fiber are lightweight, breathable, and recyclable.
Polylactic acid is extensively used in the packaging industry. Major companies have all begun using compostable packaging for environmental reasons.
If your businesses currently uses any of the following items and you’re passionate about sustainability and reducing your business’s carbon footprint, then polylactic acid packaging is an excellent option for:
