1 for selected small-scale CDM project activit categories TY III - OTHER PROJECT ACTIVITIES Project participants shall take into account the general guidance to the methodologies information on additionalit abbreviations and general guidance on leakage provided at III.V. Decrease of coke consumption in blast furnace b installing dust/sludge reccling sstem in steel works Technolog/Measure: 1. This methodolog comprises project activities which decrease coke consumption in a blast furnace of steel works b feeding direct reduced iron (DRI) pellet into the blast furnace. The DRI pellet is produced b dust/sludge-reccling sstem from dust/sludge 1 which is not currentl utilized inside the works but sold outside and/or land filled; 2. The technolog/measure covered b the methodolog is dust/sludge-reccling sstem which produces DRI pellet from dust/sludge. The sstem enables steel works to utilize the dust/sludge which currentl cannot be utilized inside the works. The examples of the sstem are Rotar Hearth urnace (RH) Waelz and Primus; 3. This methodolog is applicable under the condition that Alternative Material 2 that can be used b the Outside User 3 instead of the dust/sludge is abundant in the countr/region demonstrated according to the following procedures: Step 1: A list of possible Alternative Materials is prepared based on the historic and or present usage of materials b the outside user relevant literature and interview with experts. Step 2: The suppl situation for each tpe of possible Alternative Material k is assessed and the abundance of availabilit is demonstrated using one of the approaches below: Approach 1: Demonstrate that there is alternative material in the region of the project activit which is not full utilized. or this purpose demonstrate that the quantit of material is at least 25% larger than the quantit of dust/sludge that is being sold outside; Approach 2: Demonstrate that suppliers of Alternative Material in the region of the project activit are not able to sell all of their Alternative Materials. or this purpose project participants shall demonstrate that a representative sample of suppliers of the Alternative Material in the region had a surplus of Alternative Material (e.g. at the end of the period during which Alternative Material is sold) which the could not sell and which is not utilized. 1 Dust/sludge is material which is generated from steel making processes (e.g. coke oven blast furnace and converter). 2 Alternative Material is defined as the material that can be used b the Outside User instead of dust/sludge after the project implementation. 3 Outside User is defined as the entit which bus the dust/sludge from the steel works in the baseline. 1/10

This methodolog is onl applicable to the project activit implemented in existing steel works. 5. Measures are limited to those that result in emission reductions of less than or equal to 60 ktco 2 equivalent annuall. Project Boundar 6. The project boundar is the phsical geographical site of the steel works where dust/sludge is generated and dust/sludge-reccling sstem is to be installed. Baseline Emissions 7. The baseline scenario for the project activit is the situation where in the absence of the project activit no dust/sludge reccling sstem would be installed in the steel works and the dust/sludge which currentl cannot be utilized inside the works would continue to be sold to outside user and/or land-filled. 8. Project participants shall appl steps 1-3 of the latest version of Combined tool for identification of baseline scenario and demonstrate of additionalit to identif the baseline scenario. The methodolog is onl applicable if the identified baseline scenario is the continuation of current practice. The plausible alternative scenarios shall include but not limited to: AS 1: Continuation of current practice (i.e. dust/sludge which is not currentl utilized inside the works is sold to outside users and/or land filled) AS 2: All the dust/sludge is reccled inside the steel works with dust/sludge reccling sstem (the proposed project activit undertaken without being registered as a CDM project activit) AS 3: The dust/sludge is reccled inside the steel works without dust/sludge reccling sstem 9. The emission source in the baseline scenario is coke consumption in blast furnace. The project activit results in the decrease of coke consumption. The baseline emissions are determined as follows: BE = BE coke (1) BE Baseline emission in ear (tco 2 /ear) BE coke CO 2 emission associated with decreased coke consumption in the blast furnace due to the input of DRI pellet produced b the project activit in ear (tco 2 /ear) 10.

The emission sources in the project activit consist of CO 2 emission from electricit and fuel consumption b dust/sludge reccling sstem. In case the project activit utilizes the dust/sludge that would have been landfilled in the absence of the project activit CO 2 emission from the carbon contained in the dust/sludge should also be included in the project emission calculations. ele + fuel + DS = (7) Project emission in ear (tco 2 /ear) ele CO 2 emission associated with electricit consumption b dust/sludge reccling sstem (tco 2 /ear) fuel CO 2 emission associated with fuel consumption b dust/sludge reccling sstem (tco 2 /ear) DS CO 2 emission associated with the carbon contained in the dust/sludge which would have been landfilled in the absence of the project activit (tco 2 /ear) 16. ele is calculated based on the latest version of the Tool to calculate baseline project and/or leakage emissions from electricit consumption. 17. fuel is calculated from the following methods: (a) (b) If the fuel used b the dust/sludge reccling sstem is fossil fuel the latest version of Tool to calculate project or leakage CO 2 emissions from fossil fuel combustion is used to determine the CO 2 emissions; If the fuel used b the dust/sludge reccling sstem is off gas generated from the steel making process such as coke oven gas (COG) and blast furnace gas (BG) the CO 2 emission is determined as follows: (i) In case the dust/sludge reccling sstem uses the off gas which would not be used for an purpose but be flared in the absence of the project activit is zero; fuel 5/10

DS is calculated from the formula below: = * CC *44/12 (9) DS DS L DS DS L uantit of the dust/sludge which would be landfilled in the absence of the project activit in ear on a dr weight basis (t-dr-ds /ear). This is calculated based on the procedure described in the paragraph 19 CC Carbon content of the dust/sludge which would be landfilled in the absence of the DS project activit on a dr weight basis (t-c/t-dr-ds). This should be determined as the average of the carbon content of the dust/sludge which was landfilled for the most recent three ears prior to the implementation of the project activit 19. DS L is determined conservativel as the maximum of the two values below under 19(a) and 19(b): (a) The average of the historical annual quantit of the dust/sludge which was landfilled for the most recent three ears prior to the implementation of the project activit; ( + )/ 3 (10) = + DS L DS L n DS L n 1 DS L n 2 4 It is assumed here that the consumption of the off gas b the project activit results in increased fossil fuel consumption b existing steel making process which currentl uses the off gas as a fuel. 6/10

If the equipment of dust/sludge reccling sstem is transferred from another activit or if the existing equipment is transferred to another activit leakage is to be considered. 21. If the dust/sludge is sold to Outside User for thermal application the use of alternative material to replace the dust/sludge b the Outside User after the project implementation will lead to CO 2 emission as the dust/sludge contains carbon. This CO 2 emission needs to be considered as leakage. The amount of leakage emission can be assumed to be the same as the amount of CO 2 which would have been emitted from the dust/sludge in the absence of the project activit. 22. Even if the dust/sludge is sold to Outside User as an iron source in the case that the alternative material identified in accordance with the approach stipulated in the paragraph 3 contains certain amount of carbon the CO 2 emission due to the use of the alternative material b Outside User needs to be considered as leakage. Emission reductions 23. Emission reductions are calculated as follows: ER = BE LE (12) 7/10
