Dear Tabrika Ilyass, I would suggest starting by procuring the governmental statistics from Morrocco and then follow with Spain, Algeria, Italy and Greece, Turkey and Egypt. This would give you a very good snap shot of the panorama. It comes to mind that wine grape wastes would be significant in Spain, Italy and Greece. Tomatoes that are processed should have significant waste which might recoverable. Other crop wastes which could be concentrated for recovery is olive wastes. Country statistics might be available through the Agricultural departments of the respective countries under the production statistic.
