Dyeing of polyester fabrics is usually done at high temperatures with the use of carriers and dispersants, which are often toxic. Standard dyeing methods not only consume large amounts of energy but also contribute significantly to environmental pollution. In this work, standard and alternative methods of dyeing polyester fabric with Disperse Red 6...

The Draft Tube Spout-Fluid Bed (DTSFB) is obtained by inserting a draft tube into a bed and introducing an auxiliary gas flow for aeration in the annular region. A specific modification of this system is a hydraulic barrier, which is an extension of the column from the bottom and whose diameter is smaller than the diameter of the column. The barrie...

Agricultural waste holds significant potential as a source of nutritionally valuable components but remains largely underutilized. Oilseed crop leaves, in particular, are rich in proteins, with the enzyme RuBisCO comprising a major portion of the protein fraction. However, RuBisCO extracted using standard methods often exhibits limited solubility, ...

This study investigates the valorization of burnt IQOS cigarette waste into biochar and its subsequent activation to enhance structural porosity and surface area for environmental applications. Initiated by pyrolyzing the residual waste at high temperatures, the process yields a carbon-rich biochar, which is then subjected to a chemical activation ...
