Influence of pressure and time on extraction process using supercritical CO2 [PDF]
The supercritical fluid extraction (SFE) by carbon dioxide (CO2) of Salvia officinalis L. was investigated. SFE by CO2 was performed at different pressure (80, 100, 150, 200 and 300 bar) and constant temperature of 40ºC (all other extraction conditions ...

Pine bio‐oil based biorefinery procedure for the production of antioxidants, acids, and sugars
Abstract In this study, a wood‐based biorefinery with Pinus halepensis biomass was developed to obtain acids, sugars, and antioxidants with high recovery yields. Pine wood residues from sustainable forest management are transformed into bio‐oil (BO) and separated into value‐added chemicals with an integrated and innovative methodology.

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

A Review of the Use of Chemical Stabilisation Methods for Lithium‐Ion Batteries
The review reveals that while chemical stabilisation techniques for recycling EOL LIBs are widely used, many studies overlook safety risks, focusing on quick, low‐cost methods. Only a few studies address the associated hazards, highlighting the need for safer, well‐understood stabilisation processes in battery recycling. ABSTRACT The increasing amounts
