Valorization of date seeds for preparation of bio activated carbon

Abstract

The date industry currently produces thousands of millions of metric tons of waste per year. Hence, there is an urgent need to find suitable applications for this waste which are still largely unused. The aim of this research is to value date waste and its potential application for water treatment. Three types of activated charcoal were prepared from the seeds of dates. Different essays were done for each material prepared (moisture rate and ash, pH, concentration, mass, granulometry). The Materials obtained were characterized by different methods like FTIR and BET. The results obtained indicate that the materials prepared from date seeds are low-cost activated carbon with an effective surface similar to commercial activated carbon which has an important economic advantage through the valuation of these wastes.

A Comprehensive Review of the Nutritional Composition and Toxicological Profile of Date Seed Coffee (Phoenix dactylifera)

“…In addition to food production, studies have explored other possibilities for reusing date seed waste. A recent study demonstrates that activated carbon can be produced from date seeds, which can be used for water treatment to remove waste and suspended matter [85]. The high polyphenolic content of date seeds may also be beneficial for the nutricosmetic and pharmaceutical industries [28].…”
