Industrial biomass: source of chemicals, materials, and energy!: implications and limitations of the use of biomass as a source for food, chemicals, materials and energy Ghent University

Erick Vandamme, Tom Anthonis, Sofie Dobbelaere, Philippe Bourdeau, Dirk Carrez, Derrick Gosseling, François Huyghe, Jan Kretzschmar, Erik Meers, Leo Michiels, et al.
Biomass seemed a very promising resource for substituting fossil hydrocarbons as a renewable source of energy and as a sustainable raw material for various industrial sectors. However, during the first decade of the 21st century, competition between the use of biomass for food and feed on the one hand, and for energy and industrial applications on the other hand, became a big issue. Dramatic food price rises in the first half of 2008 were blamed ...

Chlorella vulgaris as a green biofuel factory : comparison between biodiesel, biogas and combustible biomass production Ghent University

Myrsini Sakarika, Michael Kornaros
Biofuels are viewed as the answer to safeguard the currently challenged energy security. To this end, the present study provides a comparison between approaches regarding microalgal biomass conversion to bioenergy, with a view on sustainable implementation. The energetic valorization of Chlorella vulgaris biomass cultivated under heterotrophic, sulfur-limited conditions was investigated through the biofuels biodiesel, biogas (biomethane) and ...

Biomass of annual forage crops for biogas production Research Institute for Agriculture, Fisheries and Food

Alex De Vliegher, Chris Van Waes, Joost Baert, Steven Van Hulle, Hilde Muylle
In Merelbeke (Flanders) a monoculture of maize (+ rye as a catch crop) and a 3 year crop rotation of maize, Italian ryegrass (IR, Lolium multiflorum), 1 cut IR + sorghum (+ rye as a catch crop) were compared in terms of biomass production (organic matter yield) (OM) for methane production. Two N- fertilizer regimes were conducted for the annual crops: a moderate and extensive N-regime (i.e. moderate x 0.6). During a period of 3 years there was ...

Study of the potential valorisation of heavy metal contaminated biomass via phytoremediation by fast pyrolysis: Part I. Influence of temperature, biomass species and solid heat carrier on the behaviour of heavy metals Hasselt University

Caroline LIEVENS, Jan YPERMAN, Jaco VANGRONSVELD, Robert CARLEER
Presently, little or no information of implementing fast pyrolysis for looking into the potential valorisation of heavy metal contaminated biomass is available. Fast pyrolysis of heavy metal contaminated biomass (birch and sunflower), containing high amounts of Cd, Cu, Pb and Zn, resulting from phytoremediation, is investigated. The effect of the pyrolysis temperature (623, 673, 773 and 873 K) and the type of solid heat carrier (sand and fumed ...

Combining woody biomass for combustion with green waste composting: effect of removal of woody biomass on compost quality Research Institute for Agriculture, Fisheries and Food

Bart Vandecasteele, Christophe Boogaerts, Elke Vandaele
The question was tackled on how the green waste compost industry can optimally apply the available biomass resources for producing both bioenergy by combustion of the woody fraction, and high quality soil improvers as renewable sources of carbon and nutrients. Compost trials with removal of woody biomass before or after composting were run at 9 compost facilities during 3 seasons to include seasonal variability of feedstock. The project focused ...
