Study shows PLA does not produce persistent microplastics

In the Netherlands, a new meta-study report commissioned by Holland Bioplastics, an association advancing bioplastics knowledge worldwide, concludes that the fundamental characteristics of polylactic acid (PLA), a biobased polymer made entirely from fermented plant sugars, and the hydrolysis process indicate that PLA does not produce persistent microplastics. The literature research, completed by HYDRA Marine Sciences, a research laboratory, shows that unlike non-biodegradable polymers, which will persist and permanently accumulate as nano- or microplastics in the environment, PLA will hydrolyze into molecules of ever-smaller size, becoming soluble in water and eventually fully biodegraded.

The report’s findings were drawn from an initial scan of over 30,000 reports, of which 500 were identified by HYDRA as relevant and of sufficient quality for deeper review. The research confirmed that the environmental degradation of PLA is mainly driven by hydrolysis, an abiotic process that occurs in the presence of moisture or humidity. As long as these conditions prevail, the molecular weight and size of any PLA objects or fragments will continually decrease via hydrolysis, at a rate determined by temperature, until the polymer chains are so short that the material becomes soluble in water. These soluble substances, oligomers and lactic acid monomers, will subsequently be biodegraded by microorganisms into biomass, water, and carbon dioxide.

Today's KNOWLEDGE Share : External Lubricant

Today's KNOWLEDGE Share

Some molding compounds contain a so-called "external lubricant". It is essentially a second immiscible polymeric material with a much lower viscosity.

What happens when you mold such materials ?

In extrusion things are quite obvious.The hydrodynamic forces push the dispersed lubricant to the surface of the die where they can act as expected and promote slip of the major phase polymer.

In Injection Molding the combination of the Fountain flow, moving inner flow layers to the very edge, and the presence of a frozen skin, create a more complex situation.

The high shear layer where lubricant will accumulate is INSIDE the frozen skin ! While this can still help to reduce the pressure to fill, this situation will also induce a serious risk of blistering/delamination.

This delamination was well known for instance in the Xenoy grade made of PC/PBT. But other compounds, containing for instance a silicon based lubricant, will produce the same result, as reported by some of my customers.

So, keep in mind that the lubricant (possibly necessary at the outer surface of the molded part if the intention is to control friction coefficient) doesn't quite go where you'd hope to see it.

Note that this delamination can also occasionally be observed in pure HDPE if the molecular weight is high enough. In this case the low molecular tail (waxes) will accumulate at the frozen skin interface, promoting delamination.

NOKIAN TYRES AND UPM PARTNER TO INTRODUCE THE FIRST CONCEPT TIRE MADE WITH A NEW RENEWABLE MATERIAL WITH THE POTENTIAL TO REPLACE CARBON BLACK IN TIRES

Nokian Tyres, a leading developer and manufacturer of premium tires, and UPM, a leading biomaterials production expert, are partnering to further increase sustainability in the tire industry by introducing the first concept tire made with a new renewable material with the potential to replace a significant part of the carbon black currently used in tire production.

The innovative material, called UPM BioMotion™ RFF is a promising fully renewable lignin-based alternative for traditional carbon black, reducing the need for fossil materials and lowering carbon emissions in tire manufacturing.

Nokian Tyres has long been innovating to use the material and has registered a patent for using the material in tire applications. Nokian Tyres is now licensing its patent to UPM, which enables UPM to provide the raw material to the tire industry. UPM will produce the material at its soon to be ready biochemicals biorefinery in Leuna, Germany.

“Our partnership with Nokian Tyres marks the exciting entry of our Renewable Functional Fillers into the global tire markets. In successfully demonstrating their application value, it helps us to lay the groundwork for scaling our biorefinery business so that we can make a significant contribution to the sustainable transformation of the mobility sector and beyond,” says Michael Duetsch, Vice President Biochemicals at UPM.

Nokian Tyres Green Step Ligna - the first ever concept tire made with the fully renewable lignin raw material UPM BioMotion™ RFF

Nokian Tyres Green Step Ligna concept tire is the first ever tire made with UPM BioMotion™ RFF, a fully renewable wood-based lignin raw material produced by UPM. In the concept tire all fossil carbon black in the tire’s sidewalls is replaced by the new raw material.

“With the concept tire we demonstrate the usability of the groundbreaking new raw material in tires. Our concept tire marks a leap towards the use of renewable materials not only for us, but the whole tire industry. By prototyping this renewable material in our tires, we aim to set new standards for environmental responsibility,” says Teemu Soini, VP, Innovations & Development at Nokian Tyres.

Features superior to carbon black:

“We are constantly working on innovations that advance us towards our target of increasing the share of recycled or renewable raw materials in tires to 50 percent by 2030. Since 2022 a portion of the carbon black used by Nokian Tyres has been from recycled materials. We see lignin as a promising renewable alternative to traditional carbon black, and in the future, we hope to see that lignin based renewable filler materials would find their way to tires as well complementing an increasing share of recycled content.
