“…Summarizing, improvements in environmental performance of bio-based epoxy resins would have a highly positive impact not only on plastics market, but also to energy market by decreasing the dependency on fossil sources, thus, potentially contributing to other indirect environmental benefits by shifting from fossil fuels to biobased fuels, where algae applications for energy purposes are showing to be a potential source for variety of application such as biofuels [53], [54], biogas [55]- [57] and biomethane [58], [59]. Bechstrom et al 2020 [51] concluded that there are already economically competitive pathways for production of algae-based biopolymers.…”

Epoxy resins are widely used polymers from which a variety of products are derived and applied in many industries. Most epoxy resins are still obtained from mainly fossil feedstocks, such as epichlorohydrin and bisphenol A, which are also highly toxic. Additionally, fossil derived epoxy resin products are forming non-biodegradable waste at their end of life. Recently the number of studies aiming to find solutions and other raw materials for the replacement of fossil derived epoxy resins has increased, showing that bio-based epoxy resins are a promising alternative. An interesting alternative raw material for bio-based epoxy resins is epoxides derived from microorganisms, such as epoxidized microbial oil. This review article explores and compares the latest solutions for the use of microbial oils in the production of bio-based epoxides, outlines the prospects for their future use and points out the shortcomings of these solutions.

“…Processing of marine macroalgae through a biorefinery approach could enable the generation of cost-effective products and a sustainable valorisation with minimal waste or even the fulfilment of the zero-waste concept [ 10 , 11 , 12 , 13 ]. The amount of easily degradable carbohydrates in macroalgae typically ranges between 25 and 60% dry wt [ 5 ].…”

Characterization and Bioactivity of Polysaccharides Separated through a (Sequential) Biorefinery Process from Fucus spiralis Brown Macroalgae

et al. 2022

Marine macroalgae biomass is a valuable renewable resource that can be used for the development of bioeconomy through the valorisation of valuable compounds. The aim of the current study is separate macroalgal polysaccharides with bioactive properties from brown macroalgae Fucus spiralis based on a designed biocascading biorefinery approach. Thus, we applied an integrated processing method for the separation of fucoidan and alginate, in addition to characterization through IR spectroscopy and 1H NMR. The bioactivity potential (antioxidant activity using superoxide anion and DPPH radical scavenging analysis) of the two polysaccharides was evaluated, together with DNA binding studies performed though voltametric techniques and electronic spectroscopy titration. In terms of results, functional groups S=O (1226 cm−1), N=S=O (1136 cm−1) and C-O-SO3 (1024 cm−1), which are characteristic of fucoidan, were identified in the first polysaccharidic extract, whereas guluronic units (G) (1017 cm−1) and mannuronic units (M) (872 and 812 cm−1) confirmed the separation of alginate. The DNA binding studies of the isolated polysaccharides revealed an electrostatic and an intercalation interaction of DNA with fucoidan and alginate, respectively. Both antioxidant activity assays revealed improved antioxidant activity for both fucoidan and alginate compared to the standard α-tocopherol.
