“…Regarding diterpenes, more than one million tons a year [ 147 ] of residue is produced after steam distillation of pine resin to recover the volatile fraction called turpentine. The consequent by-product is the gum rosin, which is a mixture of resin acids (90–95%) and other neutral compounds.…”

Plant Secondary Metabolites: An Opportunity for Circular Economy

et al. 2021

Moving toward a more sustainable development, a pivotal role is played by circular economy and a smarter waste management. Industrial wastes from plants offer a wide spectrum of possibilities for their valorization, still being enriched in high added-value molecules, such as secondary metabolites (SMs). The current review provides an overview of the most common SM classes (chemical structures, classification, biological activities) present in different plant waste/by-products and their potential use in various fields. A bibliographic survey was carried out, taking into account 99 research articles (from 2006 to 2020), summarizing all the information about waste type, its plant source, industrial sector of provenience, contained SMs, reported bioactivities, and proposals for its valorization. This survey highlighted that a great deal of the current publications are focused on the exploitation of plant wastes in human healthcare and food (including cosmetic, pharmaceutical, nutraceutical and food additives). However, as summarized in this review, plant SMs also possess an enormous potential for further uses. Accordingly, an increasing number of investigations on neglected plant matrices and their use in areas such as veterinary science or agriculture are expected, considering also the need to implement “greener” practices in the latter sector.

“…Such a trend stems not only from the urgent need to replace some of the most worldwide used petro-derived polymers (such as PET, the third most produced polymer worldwide) with alternative eco-friendly materials, but also from the need to find new enhancement patterns for biomass and biowaste. [1][2][3][4][5][6][7] By way of example, great efforts are applied today, supported by major research centres and big companies, such as Danone, Coca Cola, and Pepsi Cola, to produce poly(ethylene terephthalate) from renewable resources (bio-PET for bio/plant-bottles) or to develop analogous bio-based polymers. 6,[8][9][10][11][12][13] Within this field of research, new aromatic and bio-based monomers have been identified as potential substitutes of terephthalic acid.…”

“…In addition to the direct use as monomers in condensation polymerizations, these compounds can be converted into, for example, corresponding di(meth)acrylate, divinyl, diallyl, and diepoxide derivatives, which can be polymerized to form a wide variety of different materials. 5 Rigid bioderived diol monomers are required for polymers with high glass-transition temperatures ( T g ’s). In this respect, bicyclic isosorbide is one of the most accessible ones and has therefore been extensively investigated in polymer science.…”

Chemically Recyclable Poly(β-thioether ester)s Based on Rigid Spirocyclic Ketal Diols Derived from Citric Acid

et al. 2022

Incorporating rigid cyclic acetal and ketal units into polymer structures is an important strategy toward recyclable high-performance materials from renewable resources. In the present work, citric acid, a widely used platform chemical derived from biomass, has been efficiently converted into di- and tricyclic diketones. Ketalization with glycerol or trimethylolpropane afforded rigid spirodiols, which were obtained as complex mixtures of isomers. After a comprehensive NMR analysis, the spirodiols were converted into the respective di(meth)acrylates and utilized in thiol–ene polymerizations in combination with different dithiols. The resulting poly(β-thioether ester ketal)s were thermally stable up to 300 °C and showed glass-transition temperatures in a range of −7 to 40 °C, depending on monomer composition. The polymers were stable in aqueous acids and bases, but in a mixture of 1 M aqueous HCl and acetone, the ketal functional groups were cleanly hydrolyzed, opening the pathway for potential chemical recycling of these materials. We envision that these novel bioderived spirodiols have a great potential to become valuable and versatile bio-based building blocks for several different kinds of polymer materials.
