Annex B – Raw data on occurrence of HMF in bee feed
<p>HMF_raw_occurrence_zenodo.CSV contains the raw occurrence dataset on hydroxymethylfurfural (HMF) contaminant as extracted from EFSA DWH in August 2021 on 219 samples of bee feed presented in the opinion as described in its section <em>3.2.1. Occurrence data submitted to EFSA</em>. The data is provided in .csv format. This dataset is compliant with EFSA SSD model and contains two additional columns documenting issues identified in the cleaning process (column: issue) and the action taken (column: outcome) to address the issue (e.g. delete record or update values in specific fields).</p>

Data from: Comparative LCA studies of simulated HMF-biorefineries from maize and miscanthus as an example of first- and second-generation biomass as a tool for process development
<p class="MsoNormal"><span>5-Hydroxymethylfurfural (HMF) is a versatile platform chemical for a fossil free, bio-based chemical industry. HMF can be produced by using fructose as a feedstock. Using edible, first-generation biomass to produce chemicals has been questioned in terms of potential competition with food supply. Second-generation biomass like miscanthus could be an alternative. However, there is a lack of information if second-generation lignocellulosic biomass is a more sustainable feedstock to produce HMF. Therefore, a life cycle assessment was performed in this study to determine the environmental impacts of HMF production from miscanthus and to compare it with HMF from high fructose corn syrup (HFCS). HFCS from either Hungary or Baden-Württemberg (Germany) was considered. Compared to the HFCS biorefineries the miscanthus concept is producing less emissions in all impact categories studied, except land occupation. Overall, the production and usage of second-generation biomass could be especially beneficial in areas where the use of N-fertilizers is restricted. Besides, conclusions for the further development of the on-farm-biorefinery concept were elaborated. For this purpose, process simulations from a previous study were used. Results of the previous study in terms of TEA and the current LCA study in terms of environmental sustainability indicate that the lignin depolymerization unit in the miscanthus biorefinery has to be improved. The scenario without lignin depolymerization performs better in all impact categories. The authors recommend to not further convert the lignin to products like phenol and other aromatic compounds. The results of the contribution analyses show that the major impact in the HMF production is caused by the auxiliary materials in the separation units and the required heat. Further technical development should focus on efficient heat as well as solvent use and solvent recovery. At this point further optimizations will lead to reduced emissions and costs at the same time. The presented data set is the used inventory to model the environmental impacts. </span></p>

Dataset for chemorheological and rheokinetic analysis of carbohydrate-HMF-amine adhesives
<p>The work consists of primary and analysed data from rheological measurements of carbohydrate-hydroxymethylfurfural-amine adhesives. The studied adhesives are a bio-based alternative to conventional wood adhesives. The rheological properties were studied at different temperatures in isothermal (80, 90, 95 °C) and non-isothermal (20–120 °C) oscillatory measurements. Non-isothermal rheological measurements were used for the determination of the activation energy based on Vyazovskin's isoconversional method. The viscosity profile of the adhesives, determined from isothermal measurements, was fitted by an empirical model. The viscosity kinetic constant can be obtained from this empirical model and used in further rheokinetic analysis.</p> <p>Data from density and swelling experiments was measured for the characterization of the adhesive network. The determined polymer-solvent interaction parameter is included in the collected data.</p> <p>The provided datasets were used in the investigation of the reactivity and curing reaction of the studied adhesives. A discussion and interpretation of the data can be found in the previous publication Catherine Thoma, Pia Solt-Rindler, Wilfried Sailer-Kronlachner, Thomas Rosenau, Antje Potthast, Johannes Konnerth, Alessandro Pellis, Hendrikus W.G. van Herwijnen, Carbohydrate-hydroxymethylfurfural-amine adhesives: Chemorheological analysis and rheokinetic study, Polymer, Volume 231, 2021,<br> 124128, ISSN 0032-3861, https://doi.org/10.1016/j.polymer.2021.124128.<br> (https://www.sciencedirect.com/science/article/pii/S0032386121007515). Abstract: Carbohydrates as a component in adhesive formulations have been reported for many years. A rapid cure at moderate temperatures is a remaining challenge in the development of renewable adhesives. Rheology provides insight into all stages of structure formation of a cured polymer. This work analyses the curing of carbohydrate-amine adhesives with and without the addition of 5-hydroxymethylfurfural (HMF) as a biomass-derived key reactant in adhesives. Isothermal and non-isothermal rheological measurements were performed to characterize i) the rheology of the prepolymer, ii) the initial stages of curing, iii) the sol-gel transition, and iv) general rheokinetics. The viscosity profile was described by empirical models and showed a deviation from homogeneous curing. Rheokinetic analysis using isoconversional methods and Arrhenius plots showed that HMF reduces the activation energy of the curing reaction. The addition of 5 mol.-% HMF (based on starting fructose content) increases the reactivity by lowering the activation energy of the curing.<br> Keywords: Hydroxymethylfurfural; Curing; Rheology; Rheokinetics carbohydrates; Adhesives</p>
