“…The surface of the sample was analyzed before and after the recycling process [21]. Every sample was pressed against the diamond with a force ranging from 75-80 N to assure that there was an adequate contact between the sample and the ATR crystal [22]. A peak height method was employed to identify absorption bands that were collected and contrasted to absorption bands reported from several reli-able/credible references.…”

The global plastic production of 400 million tons/year has caused major catastrophes in marine environments. The current study, therefore, aimed to mitigate this challenge through the dissolution–reprecipitation method of eradicating impurities and contaminants from marine plastic debris. The results revealed that the rate of the dissolution of polyethylene (PE) outweighed polypropylene (PP) at lower temperatures. HDPE (high density polyethylene) and PP had optimal dissolution temperatures of 75 °C and 90 °C at 20 and 30 min, respectively, resulting in recovery percentages of 96.67% and 87.35% when applied to actual marine waste samples. Overall, this recycling method conserved the plastic quality and properties, making it a viable alternative for virgin plastics. The life cycle assessment (LCA) revealed that the drying stage demonstrated the greatest environmental impact within the system. The overall process, however, yielded a lower environmental impact in comparison with established findings. Conclusively, the current study has successfully restored marine plastic waste with high recovery rates and minimum chemical alterations, yielding a low environmental footprint.

“…In the future, it will be quite common to process alternative materials that will completely or partially (coprocessing) replace existing petroleum raw materials. , In this regard, it will be very important to control the quality of the obtained products, not only by existing methods according to EN 590 . Moreover, the following advanced analytical techniques were used for characterization and determination of fuel, described in previous papers: two-dimensional gas chromatography with sulfur chemiluminescence detection (GCxGC–SCD), gas chromatography with flame ionization detector (GCxGC-FID), Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR), and Raman spectroscopy. − The use of these advanced analytical methods should play a significant role in the quality control of products containing alternative materials.…”

Nowadays, sustainable biofuel production is a hot topic. However, studying the processing of new alternative materials on an industrial scale is very expensive. According to this fact, testing on pilot plants is a suitable method for studying the effects of alternative feedstocks on catalyst activity or product quality parameters. The present work deals with the effect of coprocessing used cooking oil (5−30 wt %) with refinery petroleum fractions on product properties and hydrotreating catalyst activity. The experiment was performed on a pilot unit at industrial operating conditions (5.5 MPa, WHSV 1.1 h −1 , H 2 /feed ratio 327 Nl•l −1 ) using a commercial NiMo/γ-Al 2 O 3 catalyst. Operating temperature (341−352 °C) played the most significant role in catalyst activity to get products with 10 mg•kg −1 sulfur content. The obtained products were evaluated based on the standard analytical methods specified in the EN 590 standard. Furthermore, the following advanced analytical methods were chosen for qualitative and quantitative analyses: GCxGC-FID, GCxGC-SCD, Fourier transform infrared spectroscopy with attenuated total reflectance FTIR-ATR, and Raman spectroscopy. The increase of used cooking oil (UCO) on the feed during coprocessing increased nC 15 −nC 18 alkanes with the consequent changes in the product properties such as density at 15 °C and cetane index. The increase in light gases (C 1 −C 4 ) and CO 2 indicates the promotion of the decarboxylation pathway during coprocessing. Overall, our results indicate the necessary changes in the operating conditions during coprocessing to get the EN 590 requirements with up to 30 wt % of UCO in the feed, which is the line of future advances for biofuel production at the industrial scale.
