    The ABF programme addresses one of today’s major societal challenges, how to achieve a sustainable and inclusive biobased economy, with high-level scientific research on the thin lines between food and non-food, commodities and waste products, livelihood opportunities and risks, and local and global economy. This book provides insights into the main issues and key questions relating to the biobased economy, reflects on the objectives of the ABF programme, and offers policy recommendations. It summarises the projects conducted within the three major clusters at the heart of the programme: migration and forest transformation, breakthroughs in biofuel production technology, and the commoditisation of an alternative biofuel crop. The book ends with a number of lessons learned from the ABF programme on interdisciplinary programming

    No full text
    A method has been developed for the preparation of samples for radiocarbon (14C) measurements of carbonyl compounds in the atmosphere. Sampling on 25 mL 2,4-dinitrophenylhydrazine (DNPH) coated silica gel cartridges can be carried out with up to 10.000 L of ambient air with no adverse effects on sample integrity. Methods for the selective clean-up of the extracts have been investigated.JRC.(EI)-Environment Institut
