    Europese alternatieve bron voor natuurrubber
    Meer, I.M. van der - \ 2018
    Topsector Tuinbouw en Uitgangsmaterialen - 2 p.
    biobased economy - biomass - biobased materials - rubber - taraxacum officinale
    Natuurrubber is onmisbaar voor de samenleving. De toekomstige vraag zal echter veel groter zijn dan het huidige aanbod. Bijna al het rubber is bovendien afkomstig van, kwetsbare, plantages uit Zuidoost-Azië. In dit project werken we aan een veelbelovend Europees alternatief voor de productie van natuurrubber: de Russische paardenbloem.
    A New Value Chain for Rubber and Inulin Production in the European BioEconomy
    Hingsamer, Maria ; Beerman, M. ; Jungmeier, Gerfried ; Meer, I.M. van der; Dijk, P. van; Muylle, Hilde ; Kirschner, Jan ; Kappen, F.H.J. ; Gevers, N. - \ 2017
    biobased economy - biobased materials - biomass - rubber - taraxacum kok-saghyz - inulin
    DRIVE4EU - ‘Dandelion Rubber and Inulin Valorization and Exploitation for Europe’, a European demonstration project sets up a European chain for the production and processing of natural rubber and inulin from Taraxacum koksaghyz (TKS, Rubber dandelion) to become less dependent on the import of natural rubber. Natural rubber is a sustainable material that is used for more than 40,000 products, e.g. natural rubber is applied in construction (adhesives, sealants), medicine (gloves, tubing) and transportation (matting, tyres) industries. Because of the specific quality aspects of natural rubber in many products it cannot be replaced by synthetic rubber. At the moment natural rubber is exclusively harvested from the rubber tree (Hevea brasiliensis) of which about 90% is grown in South East Asia.

    Eind augustus presenteerde bandenfabrikant Vredestein een racefietsband van rubber uit de wortels van Russische paardenbloemen. Wageningen deed veel onderzoek voor deze innovatie.

    Biobased Economy: Paardenbloem als rubberleverancier

    rubber - taraxacum kok-saghyz - inuline - materialen uit biologische grondstoffen - biobased economy - rubber - taraxacum kok-saghyz - inulin - biobased materials - biobased economy
    Natuurrubber is een onmisbaar bestanddeel in tienduizenden toepassingen, van auto- en vliegtuigband tot condooms en medische apparatuur. De Russische paardenbloem kan het Europese alternatief zijn voor natuurrubber van de rubberboomplantages in Azië en kwalitatief minder goede synthetische rubber, dat van aardolie wordt gemaakt. Ingrid van der Meer van Wageningen University & Research vertelt er alles over.

    Dandelion Rubber and Inulin
    Valorization and Exploitation for Europe',
    a demonstration project, that supports the
    development of the production chain of natural
    rubber and inulin from Russian dandelion. The
    objective of the project is to set up a European
    chain for the production and processing of
    natural rubber and inulin. This will enable the
    EU to become less dependent on the import of
    natural rubber and at the same time to respond
    to the threat of a global rubber shortage.
    Biorefinery of proteins from rubber plantation residues
    Widyarani, R. - \ 2016
    Wageningen University. Promotor(en): Johan Sanders, co-promotor(en): Marieke Bruins; E. Ratnaningsih. - Wageningen : Wageningen University - ISBN 9789462576643 - 236

    Biorefinery of rubber tree side streams could add economic value and income for farmers, who already grow the trees for latex production. The objective of this research was to design a process for the recovery of proteinaceous fractions from rubber tree. The aimed applications were expected to be suitable for local use, particularly in Indonesia, being one of the world’s largest rubber producers. Rubber seed was selected as a model biomass based on its availability (21-144 kg-protein/ha) and its oil content that enables the combination of protein and biodiesel productions within a biorefinery framework. Experimental works were focused on three parts: separation of protein and oil from rubber seed kernel, enzymatic hydrolysis of rubber seed protein into amino acids, and separation of amino acids from hydrolysate. Using alkaline extraction, up to 80% protein from the total original amount of protein in the kernel could be recovered in the extract, comparable to protein recoveries from other oilseeds and oilseed cakes. Seed type and pre-treatment had the most influence on protein recovery. Following protein extraction, the extracted proteins were recovered via isoelectric precipitation, resulting in rubber seed protein concentrate that can be used as such or can be processed further. Different protease combinations were used to hydrolyse rubber seed protein concentrate. After 24 h hydrolysis of rubber seed protein, up to 53% degree of hydrolysis and 35% protein recovery as free amino acids could be achieved. Combination of Pronase + Peptidase R resulted in the highest recovery and concentration of hydrophobic amino acids (phenylalanine, leucine, isoleucine, tyrosine, tryptophan, valine, methionine, and proline) in the hydrolysate. Some hydrophobic amino acids are essential in human and farm animal diets, therefore they can potentially be applied as a group in food and feed. Ethanol was used as an anti-solvent for selective precipitation of amino acids. Ethanol was able to selectively increase the hydrophobic amino acid fraction in rubber seed protein hydrolysate from 59% (mol/mol) in the starting material to 76% in the supernatant. Leucine and valine contributed most to this increase. The results of this study show that rubber seed proteins can be applied locally as animal feed or in industries for technical applications.

    High-performance inhoudsstoffen vinden hun weg naar de markt

    High-performance inhoudsstoffen uit biomassa ontstijgen de onderzoekslaboratoria en duiken op in proefprojecten met bedrijven en concrete toepassingen in eindproducten. Het tempo waarmee dit gebeurt en de onderliggende markt drivers verschillen per productgebied, zo blijkt uit een rondje langs biobased projecten op het gebied van kleurstoffen, farmaceutische producten/functional foods, gewasbescherming en natuurrubber.

    From a chemical perspective, nearly all building blocks for plastics can be made using renewable raw materials. However, not every process is commercially feasible. Processes often remain inefficient, products have insufficient purity or the raw materials are simply too expensive. This publication provides more insight into the processes that are currently under development and the companies involved, as well as the current development stage (from R&D to commercial production).

    A new generation of car tyres is being made with a list of intriguing ingredients. Peter Snel, group head of R&D at Dutch tyre specialist Apollo Tyres, detailed some of the differences: “We have a tyre here where we have some Guayule rubber in the tyre, instead of the normal natural rubber that we use as standard in our tyres. Here we have a tyre where we have dandelion latex in the tyre instead of the normal natural rubber.”
    Groene bouwstenen voor biobased plastics : biobased routes en marktontwikkeling

    Chemisch gezien kunnen vrijwel alle bouwstenen voor plastics uit hernieuwbare grondstoffen worden gemaakt, maar niet elke route is commercieel haalbaar. Processen zijn vaak (nog) niet efficiënt genoeg, producten hebben een te lage zuiverheid of de grondstoffen zijn te duur. Deze uitgave geeft meer inzicht in de routes waar momenteel aan gewerkt wordt en door welk bedrijf, en in welk ontwikkelingsstadium de processen momenteel zijn (van R&D tot commerciële productie).
