Is TJL PLA biopolymer edible?

TJL biopolymer is commonly used for cups, cutlery and containers. It is not recommended ingesting any plastics items such as these. While TJL biopolymer obtained SGS food standard and well-suited for a variety of packaging applications, it is not recommended for human consumption.


Does TJL biopolymer cost more than PET?

The high cost of crude oil continues to reinforce the growing need for renewable-resource-based alternatives. The cost of TJL biopolymer is comparable to other conventional plastics materials. Longer term, TJL biopolymer has the potential to even be cost advantaged compared to oil-based resins.


 

When and where will TJL biopolymer degrade?

TJL biopolymer offers the most landfill waste diversion options globally of any current commercially available plastic material. It can be physically recycled, industrially composted, incinerated, chemically converted back to lactic acid through hydrolysis (feedstock recovery) or landfilled.

TJL biopolymer is compostable in industrial composting facilities where available throughout the world. Under industrial composting facility conditions the temperature and humidity in typical sites will cause TJL biopolymer to lose molecular weight and become biodegradable to naturally occurring microorganisms.


 

Will TJL biopolymer degrade if thrown by the side of a road?

If not disposed properly, TJL biopolymer will not reach the typical composting humidity and temperature required and thus will maintain its product integrity in the near term.


 

Does TJL biopolymer degrade during usage?

No, TJL biopolymer is similar to other natural structures used for packaging, such as paper, which maintains product integrity during use.


 

Will TJL biopolymer degrade on store shelves?

TJL biopolymer will not degrade on retail shelves. TJL biopolymer is similar to other natural structures used for packaging, such as paper, which maintains product integrity during us.


 

Does TJL biopolymer emit methane when landfilled?

TJL biopolymer goes through a two-step degradation; the first step is hydrolysis where the material is reduced down to a low molecular weight (<10,000) before becoming biodegradable. At that point the molecule is a food source for naturally occurring microorganisms.

This reaction is temperature and humidity dependent. If there were typical sub-surface temperatures (>3-4 feet) and humidity, it would take decades before the polymer would degrade even to its half-life of 40,000 molecular weight. Methane is produced by organisms during the anaerobic phase of metabolism using food waste as a source in a typical landfill environment. TJL biopolymer cannot be a source of methane unless it becomes biodegradable.


 

Can I throw TJL biopolymer into my backyard compost?

TJL biopolymer should be composted in industrial compost facilities, which contain the right managed combination of temperature and moisture. Therefore, it is not recommended for use in typical backyard composting due to the lack of high temperature and inconsistent conditions.


 

Will TJL biopolymer in the recycle stream make other polymers biodegradable?

No, TJL biopolymer will not make other polymers “biodegradable.” TJL biopolymer is a base polymer and not an additive so it cannot introduce its benefits to other polymers simply by mixing them together.


 

.Will TJL biopolymer availability be impacted by the increased production of ethanol?

No, located in the heart of the “Corn Belt,” TJL biopolymer is sourced from an abundant regional supply. This supply is more than enough to meet the needs of TJL biopolymer and existing feed and ethanol production in the area.


 

Are TJL innovations only suitable for cold applications?

Although TJL biopolymer packaging is ideal for cold-fill or ambient temperature applications, such as fresh-cut produce, whole fruit, salads, fresh juice, still water and dairy products, it can also be used as an extrusion coating on paper for applications such as coffee cups. TJL biopolymer is also well suited for the film market including labels, heat-seal overlays, window films, flow wrap, twist wrap and formulations for carrier bags.


 

Can TJL biopolymer be processed (extruded, blown, injection molded, etc.) on existing conventional equipment?

Yes, TJL biopolymer can be processed in many existing operations with minimal changes. Currently, TJL biopolymer is seeing the greatest use in thermoformed, extrusion and injection stretch blow molding applications.


Are insects or rodents attracted to TJL biopolymer?

No, making TJL involves high temperatures and numerous processing steps that leaves no sugar in TJL biopolymer.  Therefore there is no food source for rodents/insects to be attracted to. In addition, similar to other polymers, after going through the multiple processing steps TJL’s physical state would not be recognized as food.
