6F.1 1 UNFCCC - NAI SOFTWARE Sector: Waste Practical Aspects and Exercises CGE Greenhouse Gas Inventory Hands – on Training Workshop for the African Region Pretoria, South Africa 18 – 22 September 2006
6F.2 2 CONTENT Specific details of the UNFCCC -NAI Software use to calculate GHG emissions in the sector Waste. Practical exercises (to be solved by the participants after the presentation).
6F.3 3 BACKGROUND The choice of a good practice method is given by the decision threes in the IPCC GPG according to national circumstances. The UNFCCC -NAI Software contains, basically, the methods of smaller complexity that can use countries for the preparation of inventories. However, in principle, the software can be used to report the estimated emissions independently of the complexity of used method (Tier 2, 3 etc).

6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Solid Waste Disposal (III) Tasks Using the UNFCCC -NAI Software: 1.Calculates Net Annual Methane Emissions from solid waste disposal. 2.Verifies the emissions report in the Sectoral and Summary Tables. 3.Fills the Table 8A (Overview Table) for the self evaluation of quality and completeness. 4.Print the used worksheet, the Sectoral Summary Table and the Overview Table (8A).
6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Solid Waste Disposal (IV) Steps 1.Open the software and select in the Waste sector the worksheet 6-1A to calculate the total annual MSW disposed to SWDSs. 2.Go to the worksheet 6-1C to calculate the Methane Correction Factor (MCF). 3.Go to the Worksheet 6-1s1 to calculate the Net Annual Methane Emissions (Gg).

6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (I) Country A: Year: Worksheet 6-2s1 to 6-2s4 Data The National Statistics Office provided the information included in the following table. Population (1000 persons) Degradable Organic Component Fraction of DOC Removed as Sludge Methane Recovered kg BOD/1000 persons/yr 00
6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (II) Other Data: Use the following values for the calculation: Wastewater Handling System Fraction of Wastewater Treated by the Handling System Methane Conversion Factor for the Handling System Collected (Sewered to plant) Lagoons (Anaerobic deep) 0,050,8 Uncollected (Treated on site) Latrines and septic systems 0,10,15 With regular sediment removal
6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (III) Tasks Using the UNFCCC -NAI Software: 1.Calculates Net CH4 emissions. 2.Verifies the emissions report in the Sectoral and Summary Tables. 3.Fills the Table 8A (Overview Table) for the self evaluation of quality and completeness. 4.Print the used worksheet, the Sectoral Summary Table and the Overview Table (8A).
6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (IV) Steps 1.Open the software and select in the Waste sector the worksheet 6-2s1 Estimation of Organic Wastewater and Sludge. 2.Specify in A that the estimation is for “all country”. 3.Enter population data in Column B, and DOC in column C. 4.Specify the Fraction of DOC removed as sludge. The software calculates the Total Domestic/Commercial Organic Wastewater (kg BOD/yr).
6F SECTOR: WASTE Exercise 6.1: CH4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (V) Steps 5.Go to the Worksheet 6-2s2 and specify in the column A the Wastewater Handling Systems used in the country. 6.Enter in B the Fraction of Wastewater Treated by the Handling Systems and in C the Methane Conversion Factor. Enter in E the Maximum Methane Producing Capacity (0,6 kg CH4/kg BOD). The software calculates the Emission Factor for Wastewater Handling System.. 7.Go to the Worksheet 6-2s4 and enter in D the Methane Recovered. The software calculates the Net CH4 emissions.
