Type of post: NEWS.

Clariant and Eta Bio have announced that a license agreement for the sunliquid® technology has been signed. Eta Bio intends to build a full-scale commercial plant for the production of cellulosic ethanol from agricultural residues at a site in Northeast Bulgaria.
Press release: “Clariant and Eta Bio announce license agreement on Sunliquid cellulosic ethanol technology in Bulgaria”, 27/7/2020.

The project is comprised of a license of a sunliquid® basic engineering package, the provision of technical services, as well as the supply of starter cultures from Clariant’s proprietary enzyme and yeast platform to process Eta Bio’s feedstock into cellulosic ethanol. The agreement marks the fourth signed license deal for Clariant’s sunliquid® technology (previous agreements: Enviral in Slovakia, ORLEN Południe in Poland, Anhui Guozhen and Chemtex in China).

Figure 1. Eta Bio plans to build a cellulosic ethanol plant in Bulgaria with Clariant’s sunliquid technology

Location
Greenfield site in General Toshevo (the Northeastern region of Bulgaria). It will utilise available land, owned by the Pavlovi family, and existing infrastructure.
Feedstock and processing capacity
250,000 tons of wheat straw (abundant resource in the region).
Products and production capacity
50,000 tons of cellulosic ethanol.

Eta Bio Ltd. has been recently established by the Pavlovi family, that manages one of the largest agricultural businesses in Bulgaria, in order to extend their business into renewable energy. This project will provide it the chance to have an additional revenue stream from agricultural leftovers. By using locally sourced feedstock, greenhouse gas savings can be maximized and additional business opportunities along the entire value chain will arise. For Bulgaria, this constitutes an essential investment in green, sustainable technologies. The produced cellulosic ethanol will be used as a gasoline additive to fulfil the country’s blending mandate for advanced biofuels, as laid out in the RED II.

Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems.

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 propiedades de flujo en frío de los productos finales. Por tanto, los HVO son

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

Biorefinery platforms – Sugars

Versión en Español BIOREFINERY PLATFORMS Concept - The sugar platform is defined as any combination of C5 (5 carbon atoms; xylose, pentose and ribose are the most common pentose sugars), C6 (6 carbon atoms; glucose, fructose and galactose are the most common hexose sugars) and/or C12 sugars (molecules containing two hexose sugar units) that exists within a pathway from biomass feedstock towards final biobased products. - These simple sugars are reactive molecules that can be converted biologically or chemically into fuels, chemicals, materials. food and animal feed. - Larger molecules such as oligosaccharides and polysaccharides are not included within the sugar platform. - The traditional processes are based on utilizing sucrose (composed of glucose and fructose) derived from sugar crops (sugar beet or sugar cane) or glucose obtained after hydrolysis of starch (founded in wheat, corn barley, rye, triticale…). - In advanced biorefineries, utilizing lignocellulosic biomass as feedst
