In the framework of the FLEXI-GREEN FUELS project the activities of BHV focused on two closely related fields of application. Therefore, promising separation sequences were conceptualized based upon the topological analysis of the feed stream compositions produced in WP5 (the upstream work package). In a second step, attractive schemes were rigorously modelled and simulated by…
Lignin valorization is one of the key challenges for the development of economically sustainable biorefineries and fast pyrolysis holds great potential for converting lignin into high-value products. However, there are still significant challenges to overcome regarding difficulties in continuous feeding and processing of lignin in fluidized bed reactors, due to melting and agglomeration of issues.…
The main objectives of WP5 are the thermochemical/catalytic upgrading of lignin and its pyrolysis bio-oil, hemicellulose and lipids streams towards aviation and/or bunker type fuels. More specifically, AUTH research focuses on the catalytic hydrodeoxygenation of the light fraction of lignin pyrolysis bio-oil towards (alkyl)cyclohexanes which can be utilized as drop-in aviation biofuels. Furthermore, mild hydrotreatment…
There is a growing demand for sustainable alternatives to fossil fuels for shipping and aviation purposes[1]. Our research within the FLEXI-GREEN FUELS project partially centers around the utilization of lipid oil sourced from black soldier fly larvae (BSFL), fed with sugars derived from municipal solid waste, for producing an alternative bio-fuel. The BSFL is a…
The main objective has been the production of lipids using oleaginous microorganisms (microalgae and thraustochytrids) as biological conversion tools of sugar streams. To maximize the sugar to lipid conversion the growth conditions for each species were optimized using commercial glucose as the carbon source. Specifically, the growth of two microalgal strains (Auxenochlorella protothecoides (AP) and…
The objective of this pilot trial was to determine the tolerance level of pure glucose in feed for Black Soldier Fly Larvae (BSFL). The results from the tolerance test will provide information on how large the glucose fraction can be when mixing cellulose from lignocellulosic biomass with municipal solid waste. The trial ran for 5…
