Issue#4 August 2023
We are pleased to share our FLEXI-GREEN FUELS newsletter with you!

This issue will inform you about our progress in work package 4, which is focusing on sugar to lipid conversion and bio-hydrogen production, coordinated by Aalborg University. In the following sections you can read about results from Luleå University of Technology, Aalborg University and ENORM working on the conversion of waste biomass to lipids by Microalgae, Thraustochytrids and Black Soldier Fly Larvae, respectively. Our  review article in Energies MDPI is a great starting point for anyone interested in understanding how to use biogenic sources to produce bio-hydrogen. In the interview with Jane Lind Sam and Dr. Tanmay Chaturvedi you will read what surprised them the most, their motivation, vision for the future and challenges of the project. Last but not least, we will inform you about our latest news: the upcoming project meeting at GreenLab.

Production of lipids by Oleaginous Microalgae and Thraustochytrids
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…
How are Black Soldier Fly Larvae responding to the inclusion of glucose to the feed?
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…
Upcycling of Municipal Solid Waste with Hermetia illucens (L.)
This study aimed to investigate the potential of using Hermetia illucens (L.) commonly called as Black Soldier fly larvae (BSFL) to upcycle organic fraction of municipal solid waste (OFMSW) into lipids, protein, and chitin. BSFL…

Jane Lind Sam, COO from ENORM Biofactory on the potential of Black Soldier Fly Larvae
"I first heard about Black Soldier Fly Larvae production about 10 years ago. I was amazed of the simplicity of growing larvae. No expensive lights, no advanced bioreactor. Just a box of feedstock and baby larvae. It turned out to be not so simple..."
Dr. Tanmay Chaturvedi from team AAU on the topic Lipid production by Black Soldier Fly Larvae.
"The feed conversion ratio shows the efficiency of converting dry feed into larvae biomass. A lower feed conversion ratio value indicates greater feed efficiency, meaning that less feed is required to produce a unit of weight gain..."

Upcoming consortium meeting at GreenLab
FLEXI-GREEN FUELS will spent 2 days in September at Greenlab in Skive to exchanging ideas and working closely together.

The H2020 EU-funded FLEXI-GREEN FUELS project aims to create a very flexible biofuels process capable of treating lignocellulosic biomass residues and organic fraction of municipal solid waste and produce a range of marketable shipping and aviation drop-in biofuel poducts and valuable by-products.
