Abstract: Most agricultural leftovers are secondary products which should be made useful by conversion to organic fertilizers, safe energy sources, oi manufactured, such as to sustain organic farming and environment anti-pollution protection. Cotton wood slicks arc among the most important leftovers, reaching in volume for Sharkia govcrnoralc to almost 121 thousands m.l. /year, representing nearly 10.4% of the corresponding estimate at country level. The paper targeted an estimation of both economic and environmental (returns of cotton wood s i n k s suggested variant uses, at both farm and regional levels, results should that farm returns may increase by nearly L.E. 296 /feddan through conversion to organic matter for fertilization. Conversion to compressed wood (MDF) would realize revenue of about L.E 6951/feddan and L.E 4931 /feddan for ami- fire untreated, and treated wood, respectively. Moreover, production as source of energy, where the total value may reach L.E. 32.7 million /year, as equivalent to almost 43.6 thousands m.t. of petrol. According, the study recommends projects, especially in Northern rural areas of Egypt, through provision of low interest - rate loans and application of rural environment protection research recommendations, besides establishing a TV. channel specia
