“…For example, during the processing of paper or fibre-based materials, adhesives may be applied to improve strength and cohesion, and, as stated above, surfaces may be coated with polymers or waxes to provide a water barrier [ 34 ]. Wrona et al [ 35 ] demonstrated how some dishes made of bamboo, palm leaf, wood and wheat pulp contained volatile compounds that exceeded the estimated daily intake limits set by the European Union. Due to the potential negative impact exceeding daily intake limits can have on human health, as well as nature upon exposure through littering, it would be beneficial to have fully bio-based packaging solutions as demonstrated in this study, which do not require adhesives to attain the required strength or barrier properties needed for certain food applications.…”

Due to environmental concerns regarding single-use plastic materials, major efforts are being made to develop new material concepts based on biodegradable and renewable resources, e.g., wood pulp. In this study, we assessed two types of wood pulp fibres, i.e., thermomechanical pulp (TMP) and Kraft pulp fibres, and tested the performance of the fibres in wet-moulding and thermopressing trials. Kraft pulp fibres appeared to retain more water than TMP, increasing the dewatering time during wet-moulding and apparently increasing the compression resistance of the pulp during thermoforming. Additionally, cellulose nanofibres (CNF) were added to the pulps, which improved the mechanical properties of the final thermopressed specimens. However, the addition of CNF to the pulps (from 2 to 6%) had a further decrease in the dewatering efficiency in the wet-moulding process, and this effect was more pronounced in the Kraft pulp specimens. The mechanical performance of the thermoformed specimens was in the same range as the plastic materials that are conventionally used in food packaging, i.e., modulus 0.6–1.2 GPa, strength 49 MPa and elongation 6–9%. Finally, this study demonstrates the potential of wood pulps to form three-dimensional thermoformed products.

“…Song et al used LC–IMS–QTOF, together with RT and CCS prediction tools, to develop a workflow for the identification of nonvolatile compounds migrating from plastic food contact materials; the authors stated that the use of predicted RT and CCS values can reduce the number of false positives in SSA. Wrona and co-workers used a LC–IMS–QTOF platform to study dishes made from biomaterials . They discovered plasticizers, lubricants, and oligomers in the dishes that most likely originated from the adhesives used in the manufacture of the bio-based dishes.…”

Ion mobility spectrometry (IMS) is a rapid gas-phase separation technique, which can distinguish ions on the basis of their size, shape, and charge. The IMS-derived collision cross section (CCS) can serve as additional identification evidence for the screening of environmental organic micropollutants (OMPs). In this work, we summarize the published experimental CCS values of environmental OMPs, introduce the current CCS prediction tools, summarize the use of IMS and CCS in the analysis of environmental OMPs, and finally discussed the benefits of IMS and CCS in environmental analysis. An up-to-date CCS compendium for environmental contaminants was produced by combining CCS databases and data sets of particular types of environmental OMPs, including pesticides, drugs, mycotoxins, steroids, plastic additives, per- and polyfluoroalkyl substances (PFAS), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs), as well as their well-known transformation products. A total of 9407 experimental CCS values from 4170 OMPs were retrieved from 23 publications, which contain both drift tube CCS in nitrogen ( DT CCS N 2 ) and traveling wave CCS in nitrogen ( TW CCS N 2 ). A selection of publicly accessible and in-house CCS prediction tools were also investigated; the chemical space covered by the training set and the quality of CCS measurements seem to be vital factors affecting the CCS prediction accuracy. Then, the applications of IMS and the derived CCS in the screening of various OMPs were summarized, and the benefits of IMS and CCS, including increased peak capacity, the elimination of interfering ions, the separation of isomers, and the reduction of false positives and false negatives, were discussed in detail. With the improvement of the resolving power of IMS and enhancements of experimental CCS databases, the practicability of IMS in the analysis of environmental OMPs will continue to improve.
