Versión en Español Type of post: NEWS. A large-scale demonstration converting biocrude to renewable diesel fuel has passed a significant test, operating for more than 2,000 hours continuously without losing effectiveness. Scientists and engineers led by the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) conducted the research to show that the process is robust enough to handle many kinds of raw material without failing. Press release: “ Biocrude Passes the 2,000-hour Catalyst Stability Test ”, 25/03/2021. Figure 1. Basic flow diagram of the whole process (Illustration by Michael Perkins, PNNL) The initial step in the process is called hydrothermal liquefaction. Wet wastes from sewage treatment and discarded food can provide the raw materials for this innovative process, which converts and concentrates carbon-containing molecules into a liquid biocrude. Just as crude oil from petroleum sources must be refined to be used in vehicles, this biocrude needs

English version Tipo de entrada: NOTICIA. Una demostración a gran escala que convierte biocrudo en combustible diésel renovable ha superado una prueba significativa, funcionando durante más de 2.000 horas de forma continua sin perder eficacia. Científicos e ingenieros dirigidos por el Laboratorio Nacional del Noroeste del Pacífico (PNNL) del Departamento de Energía de EEUU realizaron la investigación para demostrar que el proceso es lo suficientemente robusto como para manejar muchos tipos de materia prima sin fallar. Nota de prensa: “ Biocrude Passes the 2,000-hour Catalyst Stability Test ”, 25/03/2021 . Figura 1. Diagrama de flujo básico del proceso completo (Ilustración de Michael Perkins, PNNL) El paso inicial del proceso se llama licuefacción hidrotermal. Los residuos húmedos del tratamiento de aguas residuales y desechos de alimentos pueden proporcionar la materia prima para este proceso innovador, que convierte y concentra moléculas que contienen carbono en un biocrudo l

Versión en Español Type of post: NEWS IN BRIEF. Repsol plans to build Spain's first chemical polyurethane foam recycling plant at its Puertollano Industrial Complex. It will be capable of processing over 2,000 metric tons of waste per year. Press release: “ Repsol to build Spain's first polyurethane foam recycling plant in Puertollano ”, 18/03/2021. Figure 1. Repsol to build chemical recycling plant for polyurethane foam in Puertollano The polyurethane foam is the main component of mattresses, sofas and vehicle seats. At the end of its useful life, polyurethane foam is one of the most difficult plastics to process. The new recycling facility is expected to be completed by the end of 2022 and will entail an investment of approximately 12 M€. Once operational, the plant will be capable of processing around 2,000 metric tons of polyurethane foam per year. Repsol plans on using this circular economy project to produce circular polyols from recycled polyurethane foam. Polyols ar
