Fecha de publicación: 16/11/2015 Última actualización: 20/02/2016 Descripción 1,2 El ácido levulínico (también conocido como ácido 4-oxopentanoico o ácido γ-cetovalérico) es un compuesto orgánico con fórmula química C 5 H 8 O 3 . Es un sólido cristalino soluble en agua y en disolventes orgánicos polares. Contiene un grupo cetona y un grupo carboxilo cuya presencia posibilita patrones reactivos interesantes. Es uno de los “ Biobased Chemical Building Blocks ” más reconocidos, precursor de un amplio número de compuestos (véase el apartado Aplicaciones más abajo). De hecho, fue reconocido por el DoE como una de las principales moléculas plataforma del futuro y puede cubrir de manera eficaz muchas de las atribuciones de productos químicos y materiales procedentes del petróleo. Tecnologías de proceso 1,3,4,5 La degradación controlada de azúcares C6 mediante ácidos es el proceso más usado para preparar ácido levulínico a partir de biomasa lignocelulósica. Se han estu

Versión en Español Section: BIOBASED PLASTICS Series: Biobased Vinyl Polymers. - Biobased Polyethylene (bio-PE). Biobased Polyethylene (bio-PE) / Green Polyethylene / Renewable Polyethylene - Its biobased carbon content can reach 100%. - Renewable resource . It is produced from renewable biomass feedstocks as sugars or vegetable oils. - It reduces GHG emissions. Each ton produced captures and sequesters CO 2 from the atmosphere. - 100% drop-in . Chemically identical to its petrochemical counterpart. It has the same processing characteristics as fossil PE, therefore, it can be processed in the same equipment. - Non-biodegradable . It cannot be composted or biodegraded. - Thermoplastic . It can be molten and remoulded into the desired shape. - It can be recycled and processed into new bio-PE products using conventional technologies without requiring additional investments. - Building block or monomer: biobased ethylene .

Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 05/05/2021. Last update: 05/05/2021. Description - Organic acid with 3 carbon atoms. - It is a clear, colourless, corrosive liquid with a characteristic acrid or tart smell. - Other names: prop-2-enoic acid. Applications - Formation of homopolymers or copolymers which are used in the manufacture of various adhesives, coatings, diapers, detergents, paints, plastics and textiles. The main use of crude acrylic acid is the generation of acrylate esters, followed by the production of polyacrylic acid, used mostly in superabsorbent polymers. - Chemical intermediate in multiple industrial processes. Conventional petrochemical route - Cracking of fossil naphtha to produce propylene / Oxidation of propylene. Main biobased routes - [3-HPA via] Fermentation of sugars to produce 3-hydroxypropionic acid (3-HPA) / Dehydration of 3-HPA. - [Biobased naphtha via] Cracking of biobased naphth

Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 25/05/2021. Last update: 25/05/2021. Description - C6 aliphatic dicarboxylic acid. - White crystalline powder. - Other names: hexanedioic acid; 1,4-butanedicarbocylic acid. Applications - Monomer for the production of nylon 6,6. - Monomer for the production of polyurethane. - Manufacture of plasticizers and lubricants. - Gelling and acidulant agent (food grade). Conventional petrochemical route - Oxidation of cyclohexane to produce KA oil (cyclohexanone and cyclohexanol) / Nitric acid oxidation of KA oil. During the final reaction, the highly potent GHG nitrous oxide (N2O, 300 times more potent than carbon dioxide) is formed. It has been estimated that replacing the current petrochemical-based process with one employing renewable precursors will reduce greenhouse gas emissions by up to 95%, depending on the process used (1). Main biobased routes - [Muconic acid via] Fermentatio

IKEA is switching from fossil-based to bio-based glues

By
Type of post: NEWS IN BRIEF. IKEA is switching from fossil-based to bio-based glues. Today, 5% of the climate footprint of the total IKEA value chain is connected to the use of glue in board materials. With this change, the goal is to reduce fossil-based glue use by 40% and greenhouse gas emissions from glue by 30% by FY30. Press release: " IKEA to use bio-based glue for reduced climate footprint ", 01/03/2023. Finding new glue solutions is one of the main approaches to reducing the IKEA climate footprint, and most glue consumption is used in board production. As a result of innovation and several years of trials, IKEA is now switching to bio-based alternatives to reduce fossil-based glue usage by 40% and the climate footprint from glue by 30%. Switching from fossil-based to bio-based glue solutions will be a stepwise approach, and the goal is to have most board-producing factories in the IKEA supply chain using glues that have lower climate footprints by FY30.
