Pyrolysis liquids from lignocellulosic biomass have the potential to be used as a feed for aromatics such as benzene, toluene, and xylenes (BTX) using catalytic upgrading with zeolites. We here report an experimental study on the conversion of various pyrolysis oil fractions to determine the most suitable one for BTX synthesis. For this purpose, the pyrolysis liquid was fractionated using several extraction/distillation steps to give four fractions with different chemical compositions. The fractions were analyzed in detail using nuclear magnetic resonance spectroscopy, elemental analysis, gas chromatography-mass spectroscopy, thermogravimetric analysis, Karl-Fischer titration, and gel permeation chromatography. Catalytic pyrolysis experiments were carried out using a tandem microreactor with H-ZSM-5 (23) as the catalyst. The highest BTX yield of 24% (on a carbon and dry basis) was obtained using the fractions enriched in phenolics, whereas all others gave far lower yields (4.4-9%, on a carbon and dry basis). Correlations were established between the chemical composition of the feed fraction and the BTX yield. These findings support the concept of a pyrolysis biorefinery, where the pyrolysis liquid is separated into well-defined fractions before further dedicated catalytic conversions to biobased chemicals and biofuels using tailored catalysts.
Plant Breeders Rights were granted to Vandinter Semo BV on 29th December 2020 for the Andean Lupin variety COTOPAXI. COTOPAXI is result of cooperation between Vandinter Semo, Hanze University of Applied Sciences and the H2020 BBI-JU European research project LIBBIO. Andean Lupin (Lupinus mutabilis) has its origin in South America and is one of the four lupin species for human consumption. Andean Lupin is a sustainable alternative for soybean because of its comparable oil and protein content and its contribution to biodiversity and soil improvement. COTOPAXI is the first Andean Lupin variety in Europe that has been granted with Plant Breeder Rights. Andean lupin oil has excellent fatty acid composition and is therefore suited for food applications like margarines and mayonnaises and also for cosmetic applications, especially hair care products, lipsticks and nourishing anti-aging skin care products. Andean Lupin bean is also rich in proteins, oligosaccharides, alkaloids and bioactive components. Andean lupin proteins can be used as functional food ingredients and as animal feed. Oligosaccharides have functional food applications because of their fermentative (prebiotic) potential in the human large intestine. Alkaloids are of interest because of their medical potential as anti-cancer medicine and as biodegradable natural crop protection agents. Andean lupin bioactives are suited as ingredients in anti-aging cosmetics and in functional foods. Andean lupin contributes to the plant-based protein transition and to EU policy becoming more independent from foreign protein imports. Rob van Haren, Professor Transition Bioeconomy at Hanze University of Applied Sciences, says: “Andean Lupin is one of the “lost crops of the Incas” like quinoa and chia. Andean lupin grows in the same agro-ecozone as potato and has therefore a great areal potential. Andean lupin oil and protein contents are comparable with soybean and hence its business case has the same potential as well.” Rob van Haren together with other partners initiated in 2015 the H2020 research project LIBBIO for developing the Andean lupin supply chain and its biorefinery processing. This was made possible by an Andean lupin pre-breeding collection established by Kiemkracht, the innovation alliance from Product Board Arable Products and the Innovation Network of the Ministry of Agriculture. Bert-Jan van Dinter, director Vandinter Semo, says: “We have been active in plant breeding for more than a century, our company started in 1914. Our focus is to breed new varieties for soil improvement and soil health. We also breed for double-target crops for yield and soil improvement. We started our cooperation in 2008 first with Kiemkracht and later with Hanze UAS within the H2020 project LIBBIO. Obtaining Plant Breeder Rights in Europe within 5 years of research is unique. COTOPAXI is the first variety emerging from our new breeding program. In coming years we intend to breed for properties like sweetness (low alkaloids), earliness and crop yield”. The Andean lupin COTOPAXI contributes to farmer income, sustainable and circular agriculture, profitable processing and biorefinery and sustainable natural products for European consumers.
MULTIFILE
The LIBBIO project is about researching the potential of Andes Lupin for breeding cropping and biorefinery. 14 partners from 8 different EU countries cooperate together. Hanze University of Applied Sciences is technical-scientific coordinator of this 5 mio€ project. Project duration is from 2016 to 2020
De eiwittransitie slaat aan en zeewier, eendenkroos en reststromen van landbouwgewassen vormen een deel van de voedselbronnen van de toekomst. De kennis over de smaak van eiwitten en aminozuren is groeiende, maar de relatie tussen chemische structuur en smaak verdient aandacht en dat kan door te focussen op kleine peptiden en losse aminozuren. Het project “Aahminozuren!” maakt dat mogelijk. Met deze KIEM aanvraag willen de hogescholen Inholland (Delft, Amsterdam) en HZ University of Applied Sciences (Vlissingen) samen met het bedrijf Biorefinery Solutions (Raalte) verkennend onderzoek doen in een samenwerking met een helder lange termijnperspectief. Doelstelling is tot methoden te komen die het mogelijk maken om enkele kleine eiwitten - en de aminozuren waaruit die zijn opgebouwd – chemisch te karakteriseren en op een doelmatige wijze sensorisch te beoordelen. De deelnemende opleidingen zijn complementair qua expertise en hebben een gezamenlijke affiniteit voor de productie van nieuwe voedingscomponenten uit alternatieve plantaardige bronnen. Daarbij staat smaak voorop. Het langetermijnperspectief is om uit zeewier, eendenkroos en reststromen van landbouwgewassen waardevolle componenten te kunnen isoleren met een toegevoegde waarde op het gebied van smaak. De onderliggende kennis die de relaties tussen structuur en smaak verklaren zal zo kunnen worden gegenereerd, en academische kennis wordt rijp gemaakt voor toepassingen. Doel is ook om ons onderwijs met die kennis en onderzoeksmethoden te verrijken. Studenten hebben in dit project een grote rol. In juni 2021 hopen we met hen en met hun begeleiders een basis te hebben gelegd voor een verdergaande onderzoeksagenda.
By transitioning from a fossil-based economy to a circular and bio-based economy, the industry has an opportunity to reduce its overall CO2 emission. Necessary conditions for effective and significant reductions of CO2-emissions are that effective processing routes are developed that make the available carbon in the renewable sources accessible at an acceptable price and in process chains that produce valuable products that may replace fossil based products. To match the growing industrial carbon demand with sufficient carbon sources, all available circular, and renewable feedstock sources must be considered. A major challenge for greening chemistry is to find suitable sustainable carbon that is not fossil (petroleum, natural gas, coal), but also does not compete with the food or feed demand. Therefore, in this proposal, we omit the use of first generation substrates such as sugary crops (sugar beets), or starch-containing biomasses (maize, cereals).
Micro and macro algae are a rich source of lipids, proteins and carbohydrates, but also of secondary metabolites like phytosterols. Phytosterols have important health effects such as prevention of cardiovascular diseases. Global phytosterol market size was estimated at USD 709.7 million in 2019 and is expected to grow with a CAGR of 8.7% until 2027. Growing adoption of healthy lifestyle has bolstered demand for nutraceutical products. This is expected to be a major factor driving demand for phytosterols.Residues from algae are found in algae farming and processing, are found as beachings and are pruning residues from underwater Giant Kelp forests. Large amounts of brown seaweed beaches in the province of Zeeland and are discarded as waste. Pruning residues from Giant Kelp Forests harvests for the Namibian coast provide large amounts of biomass. ALGOL project considers all these biomass residues as raw material for added value creation.The ALGOL feasibility project will develop and evaluate green technologies for phytosterol extraction from algae biomass in a biocascading approach. Fucosterol is chosen because of its high added value, whereas lipids, protein and carbohydrates are lower in value and will hence be evaluated in follow-up projects. ALGOL will develop subcritical water, supercritical CO2 with modifiers and ethanol extraction technologies and compare these with conventional petroleum-based extractions and asses its technical, economic and environmental feasibility. Prototype nutraceutical/cosmeceutical products will be developed to demonstrate possible applications with fucosterol.A network of Dutch and African partners will supply micro and macro algae biomass, evaluate developed technologies and will prototype products with it, which are relevant to their own business interests. ALGOL project will create added value by taking a biocascading approach where first high-interest components are processed into high added value products as nutraceutical or cosmeceutical.
