This book is the result of remarkable contribution from the experts of interdisciplinary fields of Science with comprehensive, in-depth and up-to-date research and reviews. It describes the applications of date palm for food, medicine and the environmental sectors. Date palm is one of the oldest cultivated trees and its fruit has been a dietary staple around the world for many centuries. Date pulps contain dietary fibers and easily digestible sugars (70%), mainly glucose, sucrose and fructose. They also contain vitamins like biotin, thiamine, riboflavin, ascorbic and folic acid that are important for our body. The date palm fruit has been used in folk remedies for the treatment of various infectious diseases, cancer and immuno-modulatory activity. Date stones and date palm leaves are freely and abundantly available biomass. Therefore, the renovation of agricultural biomass wastes into activated carbons for drinking water purification, wastewater treatment, treatment of dyes, and metal-ions from aqueous solution would add value to agricultural commodities which offer a solution to environmental problems as well as reduce the cost of waste disposal.
