Production of clean agro-pellet commodities (CAPCOM) from Agro-residues

Large quantities of biomass will be needed to feed the biobased economy. Use of crops and wood may cause (indirect) land use change related greenhouse gas emissions. Agro-residues could be an interesting alternative. However, several issues are hindering efficient application: high potassium and chlorine content and low bulk density are the most...

Evaluation of Steam-Exploded Wood Pellets Storage and Handling Safety in a Coal-Designed Power Plant

Solid biofuels are currently used in increasing volumes to replace fossil equivalents. Next to the traditional wood derived fuels, the advancement of biomass upgrading technologies like steam explosion (SE), followed by pelleting, further broadens the variety of materials on the market. This thermochemical and mechanical upgrading improves...

Mutagenicity- and pollutant-emission factors of pellet-fueled gasifier cookstoves Comparison with other combustion sources

Pneumatic transport of torrefied biomass in dilute and dense phase

Pulverized coal combustion and entrained flow gasification are two of the main technologies worldwide that use coal as feedstock. In a coal-fired power plant the pulverized fuel is transported pneumatically with air in dilute phase to the boiler whereas in the second case the coal is ientrained into the gasifier in dense phase. Biomass could be...

Impacts of controlling biomass burning emissions on wintertime carbonaceous aerosol in Europe

We use a 3-D regional chemical transport model, with the latest advancements in the organic aerosol (OA) treatment, and an updated emission inventory for wood combustion to study the organic aerosol change in response to the replacement of current residential wood combustion technologies with pellet stoves. Simulations show a large decrease of...

Unlocking Streptomyces spp. for use as sustainable industrial production platforms by morphological engineering

Filamentous actinomycetes are commercially widely used as producers of natural products (in particular antibiotics) and of industrial enzymes. However, the mycelial lifestyle of actinomycetes, resulting in highly viscous broths and unfavorable pellet formation, has been a major bottleneck in their commercialization. Here we describe the...
