Elastomers play an irreplaceable role in our society due to their unique properties. Natural rubber is directly obtained from plants and is widely used in tires, shoes, etc. Recently, modified natural rubbers are proposed to expand the application of natural rubber. However, these natural rubbers have a limited variety of molecular structures and may not be able to meet ever-demanding applications. Traditional synthetic elastomers have a variety of molecular structures and their properties are used in various fields, but mainly originate from fossil resources. This review deals with bio-based elastomers, and more specifically natural rubber and bio-based synthetic elastomers. Based on reprocessability, bio-based elastomers can also be divided into bio-based chemically cross-linked ones and thermoplastic ones. Compared to traditional fossil-based elastomers, bio-based ones may alleviate environmental pollution and promote the sustainable development of the elastomer industry.

“…Large amounts of two residues are produced during shrub processing: a liquid mixture of resin/low-molecular-weight rubber and a lignocellulosic bagasse . Because of the low rubber yield from guayule (5–7 wt %), the value-added use of the resin and bagasse coproducts is important for the economic feasibility of guayule rubber; selling prices of $1.00/kg and $0.10/kg for resin and bagasse, respectively, would make guayule rubber more competitive with Hevea rubber . Guayule bagasse constitutes approximately 70–80 wt % of the shrub biomass .…”

Recovery of Nitrogen from Low-Cost Plant Feedstocks Used for Bioenergy: A Review of Availability and Process Order

et al. 2021

The cost of feedstock is often a major barrier to commercialization for lignocellulosic biofuels. Much of the research on biofuel and biobased chemical production has focused on the carbohydrate, lignin, and lipid components of biomass. There are numerous opportunities for the use of lower-cost feedstocks if more attention were devoted to the recovery and utilization of the protein and other N-containing components. This review compiles data from the last two decades on nonedible/ nonpalatable agricultural residues, deoiled seedcakes, bioethanol and biogas residues, and food wastes, with a focus on the amounts and types of N-containing components. Given the challenges of removing N-containing compounds from biofuel intermediates postconversion, a case is made for the extraction and purification of proteins (and other N-containing compounds) from low-cost lignocellulosic biomass before conversion to fuel. The goal of such processes is to avoid difficult fuel upgrading steps while enhancing the opportunities for additional biorefinery products and sustainable nitrogen cycles.

“…A techno-economic study of guayule rubber showed that costs are substantially impacted by biomass yield, rubber content, and processing byproduct value. 3 During guayule rubber extraction and separation, a substantial amount (5.5− 11 wt %) of liquid resin is produced. This resin is a mixture of low-molecular-weight rubber (LWMR) and secondary metabolites and is rich in monoterpenes, sesquiterpenes, triterpenoids, and fatty acids.…”

Guayule (Parthenium argentatum) is an alternative source of natural rubber that grows well in arid and semi-arid regions. The feasibility of guayule as an industrial crop is substantially impacted by the value of the rubber extraction byproducts, resin and bagasse. In this study, guayule resin, a complex mixture of secondary plant metabolites, was tested as a bio-based insect repellent. Whole guayule resin and vacuum-distilled resin fractions were tested against Turkestan cockroaches (Blatta lateralis Walker), both immediately after application and after being allowed to evaporate for one week. All resin fractions showed good repellency in their fresh form, with two fractions performing better than the positive control (citronella Java oil). The heavier resin fractions, which contain a mixture of lipid and oxygenated sesquiterpenes, demonstrated a persistent repellent activity against Turkestan cockroach nymphs, losing only ∼3% of their repellency after 7 days. The vacuum-distilled fractions were characterized by gas chromatography–mass spectroscopy and fatty acid methyl ester analysis. Structural similarity analysis showed that the most abundant compounds in guayule resin overlap with some active ingredients in commercial repellents. Techno-economic analysis of guayule resin-based insect repellents showed that a substantial quantity would need to be produced and sold (∼8% of the U.S. active ingredient market for residential insect repellents) in order to achieve the targeted resin selling price of 1.00 USD/kg resin.
