“…Our LCA model consists of two main stages: making (1) ESS, and (2) ESS-based composites. We built the ESS model based on the primary data from a 10 kg pilot-scale production of ESS [15]. For the biocomposite production stage, we examined a case of ESS used in a biocomposite where it is reinforced with flax fiber to functionally replace commercially available BPA-based resins [8].…”

Biocomposites can be both environmentally and economically beneficial: during their life cycle they generally use and generate less petroleum-based carbon, and when produced from the byproduct of another industry or recycled back to the manufacturing process, they will bring additional economic benefits through contributing to a circular economy. Here we investigate and compare the environmental performance of a biocomposite composed of a soybean oil-based resin (epoxidized sucrose soyate) and flax-based reinforcement using life cycle assessment (LCA) methodology. We evaluate the main environmental impacts that are generated during the production of the bio-based resin used in the biocomposite, as well as the biocomposite itself. We compare the life cycle impacts of the proposed biocomposite to a functionally similar petroleum-based resin and flax fiber reinforced composite, to identify tradeoffs between the environmental performance of the two products. We demonstrate that the bio-based resin (epoxidized sucrose soyate) compared to a conventional (bisphenol A-based) resin shows lower negative environmental impacts in most studied categories. When comparing the biocomposite to the fossil fuel derived composite, it is demonstrated that using epoxidized sucrose soyate versus a bisphenol A (BPA)-based epoxy resin can improve the environmental performance of the composite in most categories except eutrophication and ozone layer depletion. For future designs, considering an alternative cross-linker to facilitate the bond between the bio-based resin and the flax fiber, may help improve the overall environmental performance of the biocomposite. An uncertainty analysis was also performed to evaluate the effect of variation in LCA model inputs on the environmental results for both the biocomposite and composite. The findings show a better overall carbon footprint for the biocomposite compared to the BPA-based composite at almost all times, demonstrating a good potential for marketability especially in the presence of incentives or regulations that address reducing the carbon intensity of products. This analysis allowed us to pinpoint hotspots in the biocomposite’s supply chain and recommend future modifications to improve the product’s sustainability.

Please cite this article as: Adlina Paramarta, Dean C. Webster, Bio-based high performance epoxy-anhydride thermosets for structural composites: The effect of composition variables, (2016), AbstractThe structure-property relationships of a designed series of anhydride-cured epoxidized sucrose soyate (ESS) thermosets were studied. Epoxidized sucrose soyate is a novel bio-based epoxy resin derived from sucrose and soybean oil fatty acids, and it contains an average of 12 epoxy functional groups per molecule. This epoxy resin was crosslinked with methyl hexahydrophthalic anhydride to form polyester thermosets with high crosslink density, and a zinc-complex catalyst was used. In this study, the impact of composition variables-anhydrideto-epoxy molar ratio and catalyst amount-on the chemical, mechanical, and thermal properties of the thermosets were examined. All of the thermoset samples had very high gel fraction, which indicated excellent network connectivity. Samples made using an equimolar ratio of anhydrideto-epoxy groups had lower conversion of functional groups as shown by the somewhat lower gel fraction and higher moisture absorption. Analysis of the thermomechanical and tensile properties of the thermosets suggests that there is a factor interaction between anhydride-toepoxy molar ratio and catalyst amount. Furthermore, the results suggest that the molecular networks of the thermoset samples are fairly complex due to the simultaneous competing reactions between catalyst-initiated epoxy-anhydride, hydroxyl-initiated epoxy-anhydride, and epoxy homopolymerization.

There is a growing need to produce epoxidized sucrose soyate (ESS) at an industrial scale for large-scale applications in coatings and material science. Industrial scale production of ESS requires optimization of the process conditions to minimize cost without compromising resin quality. Therefore, a robust model was developed that predicts the conversion of double bonds to oxirane under different process scenarios. Data for the model were obtained by epoxidizing 30 g batches of sucrose soyate at three reactor temperatures (55, 60, and 65°C), three molar ratios of acetic acid to oil unsaturation (0.25:1, 0.375:1, and 0.5:1), three molar ratios of H 2 O 2 to oil unsaturation (1:1, 1.5:1, and 2:1), three catalyst amounts (1.5, 3.75, and 6 g), and three reaction times (3.5, 4.5, and 5.5 h). The model was highly significant with an adjusted R 2 of 97.6% and predicted R 2 of 96.8%. The root-mean-square errors (RMSE) of 0.54 showed that the model was a good fit in predicting optimal epoxidation conditions at different process levels. ESS samples epoxidized at 60−65°C for 4.5−5 h had conversion greater than 98% even when reagent amounts were reduced by 18−20%. A similar resin quality was also attained when one of the optimal conditions was scaled-up 100 fold to a 3 kg batch. Therefore, this model can be used to determine appropriate processing conditions for epoxidizing vegetable oil-based compounds at any scale with sufficient mixing and temperature control.
