Loop Industries Announces Independent Review Confirming Effectiveness of Patented Technology - Seite 2

IV. Throughout the process, the Kemitek team took samples at key steps for subsequent analysis to confirm there was no tampering by Loop's team.

V. The final purified monomers were secured by Kemitek and sent for analysis to certified external laboratories (ISO 17025). These analyses confirm the purity of the resulting monomers.

The feedstock used throughout the verification consisted of pallets of post-consumer waste PET plastic. In appearance, it was a mix of clear, gray and colored flakes and fines with a PET content varying between 86% and 95%, as determined by a Loop-conducted analysis. Feedstock contaminants identified by external laboratories mandated by Kemitek include printed film, silicone elastomer and polystyrene.

The final report issued by Kemitek, which will be filed today as an exhibit to Loop's Form 8-K, draws the below conclusions:

"The Kemitek team was able to understand, witness and verify the execution of Loop's Gen II polyethylene terephthalate (PET) depolymerization technology from feedstock to monomers. While the verification was not intended to certify the yields or economic viability of the technology, as these were out of the scope of our mandate, our observations confirmed the production of significant quantities of dimethyl terephthalate (DMT) and monoethylene glycol (MEG) from a post-consumer waste PET feedstock at both mini-pilot and pilot scales.

Characterization of the finished products also confirmed that the quality of the primary PET plastic building blocks meet Loop's specifications for the production of PET resin and polyester fiber, achieving DMT purity ranging from 99.7% to 100.1%^[1] (w/w) and MEG purity ranging from 98.2% to 98.9% (w/w). The useful monomer content for the MEG product is greater than 99.0% (w/w). This is calculated by adding the secondary PET plastic building blocks present in the final MEG product: Dimethyl isophthalate (DMI), Dimethyl Terephthalate (DMT), Diethylene Glycol (DEG), Bis-(2-Hydroxyethyl)terephthalate (BHET), 1-(2-hydroxyethyl)4-methylterephthalate (MHET) and 1-(2-hydroxyethyl)4-methylisophthalate (MHEI). It is reasonable to expect these molecules to be integrated into the final polymer chains of the PET resin and polyester fiber.
