New report highlights the potential of large-scale implementation of biorefineries in Sweden

By -


Type of post: NEWS IN BRIEF.

A new report prepared by researchers from Institute for Applied Systems Analysis (IIASA), Luleå University of Technology (LTU) and RISE Research Institutes of Sweden summarizes the results of a project focused on studying the possibilities for large-scale implementation of biorefineries in Sweden, applying an holistic multidisciplinary approach (see press release, 5/7/2018).

Figure 1. Cover of the report “Large-scale implementation of biorefineries”

The synopsis of the project can be summarised in seven highlights:
1. An increased biofuel production will not affect the production of wood products.
2. Increased biofuel targets will introduce fringe feedstocks to the fuel mix.
3. Increased biofuel targets will, in general, have limited price effects on woody feedstocks.
4. We can reach biofuel targets using many technologies and localisation options with reasonable costs.
5. Projected price effects will not affect the profitability of investments in large-scale biorefineries
6. Geography matters.
7. Centralised supply chains are preferable compared to distributed supply chains.

 The report is available online: Large-scale implementation of biorefineries. The research project has been funded by the Swedish research council Formas (dnr 213-2014-184) and was carried out between June 2015 and May 2018.

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...

Versión en Español Type of post: NEWS IN BRIEF.  Novozymes has launched Fiberex, a comprehensive platform based on novel enzymes and yeast strains to convert corn fiber into ethanol.  Press release: “ New biological platform converts corn fiber into ethanol ”, 16/09/2020.  Website: Fiberex® platform - Reimagining ethanol .  Related posts: “ Corn fiber ethanol – Examining 1.5G technologies ”, 26/4/2017. Figure 1. Fiberex platform (taken from the company website)  Typically, the starch in a corn kernel is converted into ethanol while the rest of the kernel ends up as low-value animal feed. In this remaining part of the kernel, there is a high amount of corn fiber with little to no value to the animals. Corn fiber is made up of similar building blocks as starch but is tough to break down and convert into something more useful. Fiberex is specifically aimed at breaking down tough fibers in the corn, providing producers with greater operational flexibility. ...

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: HVO - Hidrotratamiento (HVO) – Conceptos, materias primas y especificaciones - Hidrotratamiento(HVO) – Ventajas sobre el biodiesel convencional y propiedades - Biorrefinerías de Aceites Vegetales Hidrotatados (HVO) – El auge del diésel renovable - Entradas: HVO                El acrónimo HVO significa en inglés “ Hydrotreated Vegetable Oils ” (“Aceites Vegetales Hidrotratados”) o ” Hydrogenated Vegetable Oils ” (“Aceites Vegetales Hidrogenados”). Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propieda...

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...

Publication date: 15/06/2017 Last update: 24/01/2018 Introduction 1,2,3,4,5 2,5-Furandicarboxylic acid (FDCA), also known as dehydromucic acid and pyromucic acid, is an organic compound that was first detected in human urine. In fact, a healthy human produces 3-5 mg/day. It is a very stable compound. Some of its physical properties, such as insolubility in most of common solvents and a very high melting point (it melts at 342 °C), seem to indicate intermolecular hydrogen bonding. FDCA has two carboxylic acid groups, which makes it a suitable monomer for polycondensation reactions with diols or diamines. It is one of the top 12 value-added biobased chemicals listed by the US DoE in 2004. The list was updated in 2010 and FDCA was included again, but this time in a group together with furfural and 5-hydroxymethylfurfural (5-HMF). Those three molecules are the main representatives of the furanics (furan derivatives) that has been referred to as “Sleeping Giants” beca...
