As a result of increasing water consumption by pharmaceutical industries, hospitals, and the population, large volumes of liquids discharges containing pharmaceutical compounds have been generated worldwide. Even though there is a consistent contribution on the sustainable management of these contaminants, the efforts to reduce this pollution are progressing on a rather small scale. Such pollutants can be introduced into water-receiving bodies either directly, through animal and human excretions, or through unregu...

The paper aims to investigate biopolymeric wastes that combine the quality of the raw material with the desired application to obtain carbon materials. The raw materials used to obtain products for environmental application must have a low ash content and a quality as uniform as possible. Depending on the requirements of the target products used for depollution purposes, the quality characteristics of the precursors are presented: biopolymeric waste - fruit kernels/shells of peach, olive, and walnut shells, wastes...

The European Union ?circular economy? aims to maintain the value of products, materials and resources for as long as possible, minimizing the generation of waste by recycling and reusing them [1]. The leather industry generates large amounts of waste, more than 55% of raw material (hides and skin), and over 99% are stored at the landfill [2, 3]. Part of these waste generated are untreated solid waste (hide and skin), meaning around 500-600 kg per ton of raw hides [4, 5]. A way to valorize the untreated hide and sk...
