Some of the obstacles and solutions for using palm date in these applications were also explored. Considering these issues and their solutions, the date palm is a favorable alternative. Despite some limited and traditional uses of these palm wastes, this review considered date palm applications and the properties' of the most important part of that tree in recent researches and related issues for future research are also spotted.
