Facile extraction and purification methods are needed to produce guayule latex on a commercial scale. Rubber particles are released from guayule by aqueous homogenization. Acceptable latex purity is achieved by removing non-rubber particle particulates and soluble protein and other components from the homogenate in a multistep washing process. Poly...
Chapter
Enzyme catalyzed reactions can be started, stopped, and throttled by regulating ion concentration in solution. The flow of charge through solution is related to the flow of electrons through an electric circuit using electrochemistry. However, current electrochemical methods to vary ionic concentration are largely limited to the electrode surface,...

Healthcare workers across the globe rely on medical gloves to prevent the transfer of harmful bacteria and viruses between themselves and their patients. Unfortunately, due to the lack of an in-use durability standard for medical gloves by the American Society for Testing and Materials, many of these gloves are of low quality and are easily torn or...

Production of petroleum-based synthetic rubbers (SRs) causes an enormous carbon footprint for the rubber industry. Carbon footprint would be reduced if natural rubber (NR) could take a larger market share and replace significant quantities of SR. However, some SRs have higher oil resistance than NRs, and, in applications where these properties are...

Existing natural latex radiation-attenuating gloves (RAGs) contain a high loading of radiation attenuation filler that reduces their mechanical properties to below Food and Drug Administration (FDA) medical glove requirements. RAGs are commonly formulated using Hevea natural rubber latex and lead-based fillers. The former can cause life-threatening...
Article
Natural rubber (NR) has unique properties which are unmatched by synthetic rubber and is used in over 50,000 products. The only commercial source of NR is the Para rubber tree (Hevea brasiliensis) which is insecure because of increasing demand, price instability, high labor costs, trade politics, competition with other crops, defores- tation bans...
Chapter
The rubber industry is highly dependent on nonrenewable petroleum derivatives not only to synthesize elastomers, but also for fillers and other additives. Environmental concerns have driven a large number of efforts both in industry and academia to develop more sustainable, high-performance alternatives. Much of this research has focused on the uti...

Processing oils are rubber additives commonly u...
Chapter
Natural rubber (NR) is a polymer critical to modern economies. However, the entire global supply is produced by one tropical tree species, Hevea brasiliensis (para rubber tree), derived from perhaps 20 plants collected over a century ago. This species is grown as clones making it even more genetically uniform. Efforts to diversify rubber production...

Plastic production has outgrown most other man-made materials, with more than 90% being petroleum-based and non-biodegradable. Packaging, primarily food packaging, consumes the most plastic and is the largest contributor to municipal solid waste. In addition, its dependence on crude oil feedstock makes the plastic industry unsustainable and renders...

Large volumes of agricultural and food processing residues are generated daily around the world. Despite the various potential uses reported for this biomass, most are still treated as waste that requires disposal and negatively impacts the environmental footprint of the primary production process. Increasing attention has been paid toward the use...
Article
Full-text available
Guayule (Parthenium argentatum Gray) is an interesting alternative and renewable source of rubber/latex which has been used in the past. Guayule rubber and latex products are not available in the market largely because the raw material cost is higher than the current sources produced in South-East Asia and other tropical countries (Hevea brasiliens...

Bio-renewable, inexpensive, reinforcing fillers for rubber composites are being developed to replace nonrenewable versions, in order to reduce carbon footprint of production. In this study, bifunctionally silanized silica (BSS), a commercial synthetic filler, was partially or completely replaced by micro-sized eggshell (ES), at three different load...
Article
Incorporation of natural rubber (NR) into poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) through melt blending improves PHBV flexibility and toughness but sacrifices tensile strength, due to low NR modulus and insufficient compatibility between NR and PHBV. These unbalanced mechanical properties restrict NR/PHBV use in packaging applications....
Article
Rubber dandelion ( Taraxacum kok-saghyz , Rodin) is being developed as a temperate-zone source of rubber, but best agronomic practices must be determined before it can become a viable supplement to imported rubber produced from para rubber tree ( Hevea brasiliensis , hevea) plantations located mostly in Southeast Asia. In our study, the effect of p...

Apomixis is the ability of plants to produce asexual seeds, which are clones of the mother plant. The phenomenon of apomixis is tightly linked to ploidy, where diploids lack apomixis and reproduce sexually, while higher ploidy levels can exhibit apomixis. Taraxacum F.H.Wigg. species (dandelions) commonly exhibit apomixis; however, only limited stud...

Background Plant roots are used as an efficient target tissue for plant transformation assays. In root propagable species transformed roots are able to regenerate into whole plants without the addition of exogenous hormones, thus avoiding somaclonal variation associated with many plant transformation protocols. Plants grown in soil or soilless soli...

Biobutanol is a next-generation liquid biofuel with properties akin to those of gasoline. There is a widespread effort to commercialize biobutanol production from agricultural residues, such as corn stover, which do not compete with human and animal foods. This pursuit is backed by extensive government mandates to expand alternative energy sources....
