Resource caracterization and quantification General característics Potencial

Technical Viability Mechanical Recovery Pack up by manual means Before Now

Energetic viability Produced Energy Spended Energy Energy produced per ton is much higher than that consumed during material transformation, Which would be decisive to future resource profit Estilhação Mat.S/ Transf. Briquet. The most competitive process, mechanical recovery and splinter Economic viability

Atmosferic impacts CO 2 emissions from wine prunings ocurre anyway since they are burned in the vineards but:o ton. AMVDN Evita a emissão de ton CO 2 (11,7% emissions in the DNVMA Soil impacts Low variations in the soil organic mater levels Avoids disease proliferation Maintain employment levels Soil organic mater Environmental Aspects

Great available potencial at local level The great possibility to turn this residuals in a outcome and not only a single expense. This material will undoubtedly substitue fossil fuel in heating sistems, at leas at local level, becoming in the near future something useful and new Conclusions
