1 6.1 UNFCCC – NAI SOFTWARE Sector: Waste Practical Aspects and Exercises CGE Greenhouse Gas Inventory Hands-on Training Workshop

2 6.2 CONTENT Details on use of the UNFCCC-NAI Software to calculate and report GHG emissions in the Waste sector. Practical exercises (to be solved by the participants after the presentation).

3 6.3 BACKGROUND The decision trees in the IPCC good practice guidance (GPG2000) are used to choose a good practice method that suits national circumstances. The UNFCCC-NAI Software contains, basically, the methods of lesser complexity that countries can use to prepare their inventories. However, in principle, the software can be used to report the estimated emissions independently of the complexity of method used (Tier 2, 3, etc).

4 6.4 SECTOR: WASTE

5 6.5 SECTOR: WASTE CH 4 Emissions from Solid Waste Disposal

6 6.6 SECTOR: WASTE CH 4 Emissions from Solid Waste Disposal

7 6.7 SECTOR: WASTE CH 4 Emissions from Solid Waste Disposal

8 6.8 SECTOR: WASTE CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling

9 6.9 SECTOR: WASTE CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling

10 6.10 SECTOR: WASTE Exercise 6.1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (I) Country A: Year: 2000. Worksheets 6-2s1 to 6-2s4 Data The National Statistics Office has provided the information included in the following table. Population (1000 persons) Degradable organic component Fraction of DOC removed as sludge Methane recovered 18 250.515 330 kg BOD/1000 persons/yr 05 000 tonne

11 6.11 SECTOR: WASTE Exercise 6.1: CH 4 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) 0.020.8 Not specified 0.050.75 Uncollected (treated on site) Latrines and septic systems 0.30.15 With regular sediment removal

12 6.12 SECTOR: WASTE Exercise 6.1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (III) Tasks Using the UNFCCC-NAI Software: 1.Calculate net CH 4 emissions. 2.Verify the emissions report in the Sectoral and Summary Tables. 3.Fill Table 8A (Overview Table) for the self evaluation of quality and completeness. 4.Print the worksheet used, the Sectoral Summary Table and the Overview Table (8A).

13 6.13 SECTOR: WASTE Exercise 6.1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (IV) Steps 1.Open the software and select in the Waste sector Worksheet 6-2s1 Estimation of Organic Wastewater and Sludge. 2.Specify in column 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.

14 6.14 SECTOR: WASTE Exercise 6.1: CH 4 Emissions from Domestic and Commercial Wastewater and Sludge Handling (V) Steps 5.Go to Worksheet 6-2s2 and specify in column A the Wastewater Handling Systems used in the country. 6.Enter in column 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 EF. 7.Go to Worksheet 6-2s4 and enter in D the Methane Recovered. The software calculates Net CH 4 emissions.

15 6.15 ESTIMATION OF ORGANIC WASTEWATER

16 6.16 ESTIMATION OF EMISSION FACTOR

17 6.17 CH4 EMISSIONS FROM DOMESTIC AND COMMERCIAL WASTEWATER HANDLING

18 6.18 CH4 EMISSIONS FROM DOMESTICA AND COMMERCIAL WASTEWATER HANDLING IN THE SECTORAL REPORT TABLE

19 6.19 CH4 EMISSIONS FROM DOMESTIC AND COMMERCIAL WASTEWATER HANDLING IN THE SUMMARY REPORT TABLE

20 6.20 SECTOR: WASTE CH 4 Emissions from Industrial Wastewater and Sludge Handling

21 6.21 SECTOR: WASTE CH 4 Emissions from Industrial Wastewater and Sludge Handling

22 SECTOR: WASTE Indirect N 2 O Emissions from Human Sewage

23 6.23 SECTOR: WASTE Emissions from Waste Incineration

24 6.24 NEW WORSHEET 6-5S1 INCLUDED IN THE UNFCCC – NAI SOFTWARE FOR CALCULATING EMISSIONS FROM WASTE INCINERATION

25 6.25 SECTOR: WASTE Exercise for self evaluation 1: CH 4 from Solid Waste Disposal on Land (I) Country A: Year: 2000. Data  The Environment Ministry provided data on solid waste disposal in the country during the year 2000. It also provided results from studies carried out on solid waste characterization.  Determine the CH 4 emissions from the disposition of solid waste on land using the UNFCCC-NAI Software.  Verify in the Sectoral Report Table and the Summary Tables of the Inventory the report of results obtained.

26 6.26 SECTOR: WASTE Exercise for self evaluation 1: CH 4 from Solid Waste Disposal on Land (II) COUNTRY A: YEAR 2000. DATA RELATED WITH SOLID WASTES DISPOSAL Urban population of the country8 666 744 persons MSW generation rate0.68 kg/capita/day Fraction of MSW disposed to SWDSs1 Proportion of waste for each type of SWDSs Managed0.7 Unmanaged-shallow0.3 Fraction of DOC in MSW0.18 Recovered methane per year (Gg)0

27 6.27 SECTOR: WASTE Exercise for self evaluation 1: CH 4 from Solid Waste Disposal on Land (III) RESULTS CH 4 emissions from solid waste disposal on land113.73 Gg CH 4
