The potential of Jatropha curcas L. seed cake after oil extraction (expelling of seeds followed by hexane extraction) as a raw material for binderless boards was investigated. The composition of the de-oiled seed cake was investigated using a range of techniques (proximate-, ultimate analyses, TG/DG, SEM). The effects of pressing conditions like th...
This report gives a technological description of the four common collection and recycling schemes that have been tested in the Netherlands as part of the pilot beverage cartons in 2013. During this pilot the collection and recycling of beverage cartons was tested in 37 different municipalities, with various separate collection systems and 2 recover...
The emerging biobased economy is causing shifts from mineral fossil oil based resources towards renewable resources. Because of market mechanisms, current and new industries utilising renewable commodities, will attempt to secure their supply of resources. Cellulose is among these commodities, where large scale competition can be expected and alrea...
Het doel van het project “Tomaten verpakken in tomatenblad” is om een verpakking op basis van tomatenblad te ontwikkelen. Het project bestaat uit 2 fasen: fase 1 is gericht op te technologisch ontwikkeling en fase 2 op de productie van prototypes en het testen van de ontwikkelde verpakkingen onder ketenrealistische omstandigheden (ketensimulaties)....
Doelstelling van de eerste fase van het onderzoek was ‘het verkennen van kleinschalige keten(s) voor de raffinage van bietenblad’, met aandacht voor de technologische en economische haalbaarheid. Deze verkenning vormt de basis voor de volgende fase, waarin kansrijke opties verder worden uitgewerkt en openstaande vragen worden beantwoord. De eerste...

Food & Biobased Research werkt vaak aan het ontwikkelen van nieuwe technologie. Het is de vraag of en zo ja hoe de Reflexief Interactief Ontwerpen (RIO) methode toegepast zou kunnen worden binnen projecten van Food & Biobased Research. Om deze vraag te onderzoeken is gekozen voor het analyseren van de mogelijkheden voor RIO binnen een biobased voor...
RIO (Reflexief Interactief Ontwerpen) bestaat uit drie hoofdonderdelen: de (systeem)analysefase, de ontwerpfase en de verankeringsfase. RIO is ontstaan in een veehouderijcontext. Die context heeft een aantal specifieke eigenschappen, die toepassing van RIO in andere sectoren niet volledig vanzelfsprekend maakt. In een drietal projecten in de tuinbo...
Vanwege de grote diversiteit van potentiële cellulose bronnen en de grote verschillen in kwalitatieve eigenschappen en samenstelling van deze cellulose types is het van belang in kaart te brengen voor welke toepassingen de verschillende grondstoffen het meest geschikt zijn. Voor het opstellen van een dergelijke “cellulose matrix” dient aandacht te...
The invention relates to a process for refining a biomass from empty fruit bunches of oil palm with a dry matter content of 5-95 wt.%, based on the total wt. of the biomass, where the process comprises the subsequent stages of (a) water extn. under atm. pressure conditions and at pH of 5-7, (b) pre hydrolysis with water, steam or a their mixt. at 1...
De Europese import van soja voor diervoeding kan met maximaal dertig procent omlaag. Tenminste, als de technologie waar Edwin Keijsers van het Instituut Food & Biobased Research aan werkt in de nabije toekomst een succes wordt. Dan komen die eiwitten gewoon uit gras.
“Ecocoboards” is the acronym for Ecological and Economical production of coconut-based boards.
For production of compression moulded boards from whole coconut husk the auto-adhesive properties are derived from the intrinsic high lignin content. Since the properties of manufactured boards for a large part will depend on the input husk material these properties are studied here. Husks of different varieties and maturity have been investigated...
The invention relates to a method for making a biodegradable moulding and to a moulding obtainable according to the invention. In a method according to the invention a moulding is made from fibre particles, such as bran or bran-like material, which particles are subjected to a pre-treatment in order to improve the manufacturing process and/or the q...
Sulphur-free lignin coming from a novel alkaline-pulping process called NovaFiber, which has been developed by KIRAM AB, has been characterised and evaluated for potential applications. A Kraft lignin has been used for comparison. Considering the characterisation results of a NovaFiber softwood and Kraft lignin, it can be concluded that these ligni...
Coconuts are typically growing in coastal areas of tropical countries. The husk is abundantly available as cheap residue from coconut production in many areas, which is known to yield the coarse coir fibre. In this project a simple and efficient technology has been developed to produce high strength-high density board materials from whole coconut h...
Coconuts are abundantly growing in coastal areas of tropical countries. The coconut husk is available in large quantities as residue from coconut production in many areas, which is yielding the coarse coir fibre. The husk comprises ca. 30 wt.% coir fibres and 70 wt.% pith. Both fibre and pith are extremely high in lignin and phenolic content. The l...

In this study the switchgrass (Panicum virgatumL.), a biomass crop being developed in North America and Europe, was tested as a stiffening and reinforcing agent in polypropylene (PP) composites with and without maleic anhydride grafted PP (MAPP) as a compatibiliser and to evaluate the effect of pulping and different sources of switchgrass on compos...
Pretreatment methods for the production of fermentable substrates from Miscanthus, a lignocellulosic biomass, were investigated. Results demonstrated an inverse relationship between lignin content and the efficiency of enzymatic hydrolysis of polysaccharides. High delignification values were obtained by the combination of mechanical, i.e. extrusion...
