Floreon FAQ's.
As Floreon is a new technology we are aware of questions that have been raised over the years. For ease we have collected the most frequently asked questions and answered them here.
FAQ SUSTAINABILITY
From what feedstock are Floreon bioplastics made from?
​
Floreon bioplastics are currently made from plant-based feedstocks, including corn and sugarcane. In the short to medium term, we have the option to source recycled PLA, albeit at a premium. Recycled grades with post-industrial and post-consumer content ranging from 30% to 100% are available. For the longer term, we are working with our upstream supply chain partners on second-generation (2G) feedstocks such as lignocellulosic biomasses derived from farm or industrial waste streams and also third-generation (3G) sources such as algae and seaweed.

What is the carbon footprint of Floreon bioplastics?
​
From cradle-to-gate, the carbon footprint of PLA is typically 0.5-0.6 kg CO2 eq per kg of polymer, which means that Floreon bioplastics have a carbon footprint up to seven times lower than traditional fossil-based plastics, such as ABS, PC, or HIPS.
What are the End of Life (EOL) options with Floreon bioplastics?
​
Recycling
Floreon® Therma-Tech and Dura-Tech can be recycled both mechanically and chemically. Floreon has conducted its own recycling study on Floreon® Therma-Tech, in collaboration with the Biorenewables Development Centre at the University of York. The study demonstrated that the majority of lactic acid can be efficiently recovered through a simple and rapid reaction, with all flame retardants and fillers removed via straightforward filtration. This recovered feedstock can then be used to regenerate polymers without downcycling. While the infrastructure for PLA recycling is not yet as advanced as that for fossil-based polymers like polyolefins, it has been shown that NIR identification and sorting of PLA from mixed plastic waste is feasible due to its unique IR fingerprint. Currently, closed-loop collection is the preferred method for PLA recycling, but as investments in plastic waste sorting continue to grow, more facilities will be able to identify and sort PLA, enabling both mechanical and chemical recycling on a broader scale.
Composting

FAQ PROCESSING
In which processes can Floreon bioplastics be used?
​
Floreon bioplastics are versatile and can be used in a wide range of processes.
Do Floreon bioplastics need to be pre-dried?
​
For optimal results, we recommend drying Floreon bioplastics at 50°C before processing to ensure the moisture content is below 0.025% (250 ppm).
What is the optimal processing temperature for Floreon bioplastics?
The recommended melt temperature range for Floreon bioplastics is between 175°C and 240°C. The mould temperature plays a critical role in determining the polymer's structure: an amorphous structure is achieved when moulding at 25°C, while a crystalline structure is attained at 95°C, with a holding time >60s. For more comprehensive information, a detailed processing guide is available. Additionally, Floreon’s Application Engineer offers hands-on technical support during initial trials to ensure optimal performance of the bioplastic.
Do Floreon bioplastics impact cycle times?
​
If a crystalline structure is required, a minimum holding time of 60 seconds is necessary. For all other processes, the cycle time remains unchanged.
Can Floreon bioplastics be used in clear/transparent applications?
​
Floreon® Dura-Tech (substitute for ABS and PC-ABC) and Floreon® Bio-Tech (substitute for HIPS) would be translucent at low thickness’s, however parts made from Floreon® Therma-Tech (halogen-free, UL94 V-0 rated flame retardant grade, substitute for FR ABS and FR PC-ABS) can only be opaque.
Can Floreon bioplastics be coloured?
​
Floreon bioplastics can be custom colour-matched and are fully compatible with both universal and PLA-based colour masterbatches, providing flexibility in achieving precise colour requirements.
​Can other functional additives such as Antimicrobial, Antistatic or UV stabiliser be used with Floreon?
​
Functional additives, including antimicrobial agents, antistatic compounds, and UV stabilisers, can be integrated into Floreon bioplastics or introduced through a masterbatch. Floreon bioplastics are compatible with both universal carriers and PLA-based carriers.
Can Floreon moulded parts / extruded sheets or films be printed or painted?
​
Floreon bioplastics exhibit low surface energy, making them highly suitable for the application of printing inks, coatings, and adhesives. This property ensures excellent adhesion and finish quality in various surface treatments.
Can Floreon moulded parts be welded?
​
Yes, parts made with Floreon bioplastics can be solvent welded (for example, dichloromethane works well) or bonded by ultra-sonic welding.
FAQ PERFORMANCE

Are Floreon bioplastics water resistant?
​
In its crystalline form, Floreon bioplastics exhibit excellent water resistance. However, in its amorphous phase—similar to traditional PLA—Floreon bioplastics are not inherently water-resistant. While the amorphous phase offers some moisture resistance, it remains biodegradable and can absorb water over time, particularly in humid environments. Prolonged exposure to water or high humidity can cause the material to weaken, swell, or warp.
Are Floreon bioplastics resistant to chemicals and/or cleaning products?
​
Compared to standard PLA, Floreon bioplastics offer improved resistance to chemicals and cleaning products. However, we recommend verifying compatibility with specific ingredients to ensure optimal performance.
Are Floreon bioplastics UV stable?
​
To achieve optimal UV stability, it's advisable to use a UV stabiliser package. Please reach out to the Floreon technical team to discuss your specific requirements, so they can recommend the appropriate UV additives for your needs.
FAQ VIABILITY
Is there enough PLA capacity around the world to meet demand?
