In the near future, sustainable and efficient biorefineries would be essential for production of commodity chemicals high-added value compounds. Therefore, in this work, six scenarios differing on delignification steps cellulose conversion routes were assessed via Life Cycle Assessment methodology order to study environmental impacts derived from an abundant agricultural residue (almond shells)...

Glass foams is an interesting option for the use of fractions glass cullet otherwise destined to landfills. As building insulation materials, obtained by conventional processes have still some drawbacks in purity starting feedstock, which can be avoided implementing alkali activation process. Using life cycle assessment methodology, research analyses potential impacts associated foam from waste...

Ordinary concrete is an indispensable construction material of modern society which used for everything from mundane road pavements to building structures. However, it often non-load-bearing applications (for instance, insulating lightweight units) where mechanical strength not a priority. This leads avoidable depletion natural aggregates could instead be replaced by alternative waste materials...

The circular economy will play an important role in the reduction of carbon emissions and poplar might be one winning choices according to sustainable development. As for agricultural crops, high-quality production is strictly related genetic variability best management practice. main objective this study was analyze different stand options quantify differences on emission environmental impacts...

In the University Hospital of Albacete (Spain), distribution Active Pharmaceutical Ingredients (APIs) was studied to estimate occurrence most prevalent analgesics and anti-inflammatories antibiotics in patients’ urines. This estimation based on consumption amounts APIs their pharmacokinetic data. Results showed that metamizole would be drug among with estimated concentrations ranging 100 – 1000...

Abstract Purpose The study aimed to identify the environmental hotspots of lab-scale preparation high purity porous Al 2 O 3 pellets with suitable feature work properly as metal layer-based deposition substrates for hydrogen separation membranes. intention was providing hints that may help designing upscaled systems, fundamental development a possible future industrial production membranes tech...

The present study examines, compares, and documents the environmental impact of five extraction techniques through Life Cycle Assessment (LCA). material used was Moringa oleifera freeze-dried leaves assessment based on their polyphenol content Three out examined are referred to in literature as “green” techniques, namely Pulsed Electric Field (PEF), Microwave-Assisted Extraction (MAE), Ultrasou...

Soybean meal, the main protein source for livestock in Italy, is associated with high environmental impact terms of land use change. Thus alternative sources are advisable. The study aimed to evaluate through a Life Cycle Assessment (LCA) approach milk production systems characterised by different diets lactating cows including soybean. Four scenarios were identified: (1) conventional soybean m...

A thorough life cycle assessment (LCA) was conducted to determine whether wood pellets were a viable substitute for non-renewable fuels like oil and gas, especially heating. To evaluate the properties of their effects on environment, study in Hazara division Khyber Pakhtunkhwa, Pakistan. few factors investigated, including carbon water footprints identification potential growth opportunities pr...

Contextualización: el Análisis de Ciclo Vida [ACV] constituye una herramienta útil para evaluar impactos potenciales ambientales un producto. Dado creciente interés en la mitigación del cambio climático y implementación prácticas productivas sostenibles, resulta interesante estudiar perfil ambiental los productos origen agrícola, con énfasis especial aceites esenciales, identificar deficiencias...
