There are three, and only three, options to source fossil free carbon-based materials: using biomass, applying CO 2 capture and utilisation technologies, and using recycled content/materials. In our discussions with colleagues and other stakeholder we realised that it is difficult to grasp the differences and similarities between these three feedst...
This booklet is the second piece of the big puzzle called circular fashion.
For the textile industry to become sustainable, knowledge of the origin and production of resources is an important theme. It is expected that recycled feedstock will form a significant part of future resources to be used. Textile recycling (especially post-consumer waste) is still in its infancy and will be a major challenge in the coming years. T...
People have three elementary needs in order to stay alive: food, shelter and clothing. Feeding the world is gaining a lot of attention all over the world, and studies show that the food demand, even with a growing population, can be met by diet changes and crop-yield improvements. The way we shelter ourselves is slowly changing, as we are more awar...
This introductory chapter provides an overview of seaweed biorefinery opportunities, providing basis for multiple value chains, contributing to nutrition and health of a growing global population, to local job generation and development, to ecosystem services, and not the least to climate change mitigation and adaptation. A unique and rich diversit...

The use of algae for biofuel production is expected to play an important role in securing an alternative energy source in the near future, particularly in light of depleting fossil fuel reserves and the adverse environmental impact of fossil fuels. Algae presents a viable altern...
Lignin as feedstock for green chemicals and materials
Noord-Nederland (de drie noordelijke provincies) kan een grootschalige producent en leverancier worden van hernieuwbare grondstoffen voor de regionale productie van ‘groene’ chemicaliën, kunststoffen en veevoeder eiwit. Door nauwe samenwerking met het Duitse Weser-Emsgebied kan de voorziening van biomassagrondstoffen van ‘eigen bodem’ worden verste...
The goal of this booklet is to raise awareness of the concept of artificial photosynthesis and its potential to become an additional and significant new option in our longer-term energy future.
Seaweeds (also called macroalgae) are considered a potential biomass feedstock for biorefineries for production of energy and chemicals. In this study, a biorefinery strategy for the brown seaweed Saccharina latissima is described. Fresh S. latissima harvested at the Irish coast contained glucose and mannitol as most abundant fermentable sugars. Th...
Within the Biorefinery-program, Wageningen UR Food and Biobased Research creates technologies and know-how on sustainable biomass production, pretreatment, and conversion to a wide range of biobased products.
In the research area of seaweed, Food and Biobased Research is developing new seaweed biorefinery technologies for optimal usage of the seaw...
Suiker speelt een belangrijke rol in de biobased economy. Voor de chemische industrie kan suiker
als vervanging dienen van fossiele grondstoffen voor de productie van chemicaliën en materialen
zoals bioplastics. Door zeer veel partijen wordt er momenteel gewerkt aan de verdere
ontwikkeling van een scala aan chemicaliën en materialen uit suikers. Di...
In this paper we investigate the possible routes to produce the most commonly used polymers from biomass. This includes vinyl polymers, polyesters, polyamides, polyurethanes, and synthetic rubbers. Also the most promising newly developed polymers that can be produced from biomass are investigated. Approximately 80% by weight of all chemicals produc...

The breakdown of biomass in pretreatment facilitates enzymatic hydrolysis by disrupting cell wall structures, driving lignin into solution or modification of the lignin structure, and reducing cellulose crystallinity and chain length, while preventing hydrolysis of cellulose. In an ideal situation the pretreatment leads to high yields of fermentabl...
Dit onderzoek richt zich op het potentieel van zeewier productie in de Noordzee, als een duurzaam uitgangsmateriaal voor productie in diervoeders en andere non-food toepassingen. Zeewier kan geteeld worden in zogenaamde multi-use platforms at sea (MUPS). Het onderzoek geeft een overzicht van kennis over zeewier productie en toepassingen. Resultaten...
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 wor...
Barley straw, sugarcane bagasse and empty fruit bunches were pretreated under acid- and alkaline conditions. Solid phase was separated from the liquid phase and the concentration of dissolved monomeric sugars, organic acids and furanics was determined. Acid hydrolysis yielded monomeric xylose concentrations (max 20 g/l) whereas for alkaline hydroly...
De kweek van microalgen kan een belangrijke rol spelen in milieuvriendelijke productie van grondstoffen voor biodiesel. Daarnaast leveren algen tal van andere nuttige stoffen voor de levensmiddelen- en chemische industrie. Dit boekje brengt de huidige stand van zaken omtrent algenkweek in kaart. Daarnaast analyseert het de mogelijkheden van economi...
The cultivation of microalgae can play an important role in environmentalfriendly production of raw materials for biodiesel. In addition, algae offer several other useful materials for the food and chemical industry. This booklet describes the possibilities for economically viable large scale algae cultivation for the production of valuable product...
De studie beschreven in dit rapport heeft tot doel om de melkzuurketen meer in detail uit te werken, waarbij de productieketen bestaat uit de volgende onderdelen: conversie biomassa tot fermenteerbare suikers; conversie fermenteerbare suikers tot melkzuur; polymerisatie van melkzuur tot PLA. De prijzen van fermenteerbare suikers uit in Nederland be...
Dit boekje is geschreven met als doel bioraffinage meer bekendheid te geven. In hoofdstuk 1 is de Biobased Economy beschreven en de sleutelrol die bioraffinage daarin speelt, met een focus op Nederland. Bioraffinage is een zeer brede term en een classificatiesysteem is noodzakelijk; dit is beschreven in hoofdstuk 2. In de hoofdstukken 3 en 4 wordt...
Het onderzoek van Paulien Harmsen van het instituut Food & Biobased Research laat zien dat er meer mogelijk is met stro.
This report was produced to give an overview of present and future market for biorefinery products based on carbohydrates. Various studies show that there is a wealth of possible molecules and products that can be produced from carbohydrates. Carbohydrates already find significant application in starch products and cellulose plastics and fibres. Ho...
Different pretreatment technologies published in public literature are described in terms of the mechanisms involved, advantages and disadvantages, and economic assessment. Pretreatment technologies for lignocellulosic biomass include biological, mechanical, chemical methods and various combinations thereof. The choice of the optimum pretreatment p...
De centrale kennisvraag van deze studie is hoe het Nederlandse overheidsbeleid beter kan bijdragen aan de totstandkoming van de biobased economy (BBE) in Nederland. Om deze vraag te beantwoorden is het noodzakelijk om ontwikkelingen te schetsen die nodig zijn om de productieketens in de BBE tot volledige commerciële ontwikkeling te brengen, en hoe...

Proteins have unique material properties, which make them attractive for several applications including microencapsulation [1–7]. Actually, the first reported microencapsulation process, over 50 years ago, was the manufacture of microcapsules based on gelatin, intended for the development of carbonless copy paper [8]. Relevant protein properties fo...
So far, limited research is performed on technical applications of pea proteins and no applications have yet been reported. At ATO, three technical applications were investigated: surfactants, films, and microspheres as encapsulation matrices. Pea protein hydrolysates are surfactants with good emulsifying and foaming properties. By variation of enz...
Alkyl-poly(ethylene oxide) (PEO) surfactants containing a terminal hydroxyl, sulfate, or carboxylate group were grafted at the surface of poly(ethylene) (PE) samples to improve their blood compatibility. Grafting was achieved by immobilizing PEO surfactants on PE using an argon plasma treatment. The sulfate group containing PEO surfactant was synth...
