Type of post: NEWS IN BRIEF.

Circa Group AS and OQEMA AG have signed a supply and capacity reservation agreement for the sale of Cyrene™ into Europe. The agreement is for the market development and supply of several thousand tonnes of Cyrene™ per annum. This brings reservation commitments for Cyrene™ volumes to over 5,000 tonnes per annum, which will be supplied by Circa’s ReSolute™ plant, and the following FC6 plant, now at planning stage.

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

Publication date: 16/11/2015 Last update: 20/02/2016 Description 1,2 Levulinic acid (also known as 4-oxopentanoic acid or γ-ketovaleric acid) is an organic compound with chemical formula C 5 H 8 O 3 . It is a white crystalline solid soluble in water and polar organic solvents. It contains ketone and a carboxylic group whose presence results in interesting reactivity patterns. It is one of the more recognized Biobased Chemical Building Blocks , a starting material for a wide number of compounds (see Applications below). In fact, it was recognized by the US DoE as one of the top biobased platform chemicals of the future and it can successfully address many performance-related issues attributed to petroleum-based chemicals and materials. Process technologies 1,3,4,5 The controlled degradation of C6-sugars by acids is the most widely used approach to prepare levulinic acid from lignocellulosic biomass. Other methods have also been studied, for instance, the hydroly...
