Trinseo styrene plant in Terneuzen receives ISCC+ mass balance certification

By -

Type of post: NEWS.

Trinseo has announced that its feedstocks plant in Terneuzen (The Netherlands) has received the International Sustainability & Carbon Certification (ISCC) for its mass balance processes used to validate its biobased styrene as sustainable.

Trinseo’s styrene plant in Terneuzen received ISCC+ certification in December 2020 and already has produced its first batch of bio-styrene. The Terneuzen plant joins three other Trinseo sites in being certified: polystyrene at Tessenderlo (Belgium), polycarbonate at Stade (Germany) and synthetic rubber at Schkopau (Germany).

The percentage of bio-content in Trinseo’s styrene can vary based on the composition of the feedstocks. For example, the first batch of bio-styrene produced had 75 % bio-content and was made from 100 % bio-benzene blended with ethylene coming from fossil-based naphtha. Trinseo uses second generation feedstocks (biowastes) ensuring that the bio-source for the styrene does not compete with food chains.

Styrene is used to produce resins such as polystyrene (PS), acrylonitrile butadiene styrene (ABS), styrene acrylonitrile (SAN), latex binders, and synthetic rubber. Trinseo tracks both bio and recycled feedstocks at the Terneuzen facility and provide customers with sustainability declarations as evidence of sustainable content claims.

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

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
