Recycling
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 from the pressing of fruit kernels for several types of representative carbon materials used for water depollution. Physical-chemical characterization is provided as ultimate analysis. The quality parameters of the renewable biopolymers in the case of obtaining different types of carbon materials precursors.
To select the most appropriate waste to be used for targeted application, the potential for improving their characteristics was analyzed by applying a metric that consists in calculating the distance between two points belonging to the same vegetable waste for both stages (waste and char). Thus, for each type of waste, a distance was calculated for the carbon and nitrogen content, for the carbon and hydrogen content, respectively for the carbon and oxygen content. The results of the analysis indicate a ranking of the waste to be used in recycling technology.
