  1. WORK PACKAGE 5BIOLOGICAL TREATMENT

  2. PROCESSES / EQUIPMENTSC - Composting plantTube – Tube (Dano type)AD - Anaerobic digestion plant (?) MWS – Mixed waste sppliting plantMT - Mechanical treatment PT - Post-treatment

  3. Composting (C)Biological process for the treatment of the biodegradable fraction of waste, based essentially on the action of an aerobic microbial population. The material should pass through a thermophilic phase, where there is a high release of CO2, water and heat. In the end, the process should lead to the production of stabilised organic matter (compost).

  4. Anaerobic Digestion (AD)Biological process for the treatment of the biodegradable fraction of waste, based on the action of an anaerobic microbial population. Organic matter is stabilised and biogas, which contains high concentrations of CO2 and CH4, is produced. The AD process is usually followed by a C process for maturation purposes.

  5. Inputs - Mixed waste - Biowaste SC - Organic waste CP - Organic waste CO - Fraction for BT from MWS plants - Air * - Water - Supplies (Energy)

  6. Outputs- Compost - Digestate - Rejected materials - Off gas - (CO2, CH4, H2O, NH3, NOx, H2S) - Leachate - Energy

  7. Destinies for Outputs 1. Compost (C) - Agriculture - Other uses (final landfill cover, landscape restoration in old and disused quarries and mines, anti-noise barriers, road construction, golf courses, ski slopes, football pitches) - Landfilling - Incineration (?)

  8. 2. Digestate (AD)- Agriculture- Composting3. Rejected materials - Recycling- Landfilling - Incineration

  9. 4. Off gas: C - Biofilters  environment AD - Burnt (energy recovery or not)  environment5. Leachate (C) - WWTP  environment - Recirculated6. Energy (AD) - TIBS

  10. CASE STUDIES1. INPUT MATERIALS - MSW - Biowaste - Green waste (?)2. COMPOSTING PLANTS - Koch - Siloda3. TUBE - BRS

  11. 4. ANAEROBIC DIGESTION PLANT ???5. MECHANICAL TREATMENT/ WASTE SPLITTING - Trommel - Overband - Selector conveyor (after tube) 6. POST TREATMENT - Trommel - Selector conveyor - Densimetric table

  12. CASE STUDIES CONFIGURATION

  13. OR

  14. MEASUREMENTS AND ANALYSES TO BE CARRIED OUT1. Dry Modecom Procedure2. Measurements in situ(composting park)- temperature - O2, CO2 and CH4

  15. 3. Composting material and final compost- moisture - volatile solids (organic matter) - inerts - heavy metals - synthetic and non-synthetic organic matter - total N - SOUR

  16. 4. Final compost - self-heating test - phytotoxicity assay (germination test) - Salmonella, E.coli - P, K, Ca, Mg, Na, Cl, pH, electrical conductivity, humic compounds

  17. CASE STUDY ALREADY PERFORMEDTratolixo Plant

  18. TRATOLIXO

  19. WET MATTER BALANCE - FLUXES

  20. WET MATTER BALANCE - COEFFICIENTS

  21. WET MATTER BALANCE - SUMMARY(values relative to total input of MSW)

  22. ORGANIC NON SYNTHETIC MATTER BALANCE - FLUXES

  23. ORGANIC NON SYNTHETIC MATTER BALANCE - COEFFICIENTS

  24. NON SYNTHETIC ORGANIC MATTER BALANCE - SUMMARY

  25. NEXT 6 MONTHS1. Biowaste composting plant2. Measurements for the Tratolixo composting park- in situ: temperature, oxygen, carbon dioxide- SOUR3. Study of individual equipments for MSW / MT and PT (3)
