Reports of New Mechanisms Feasibility Studies: FY2011

Title of Feasibility Study (FS)New Mechanism Feasibility Study for CO2 Abatement through Utilisation of Blast Furnace Slags as Blending Material for Cement in Viet Nam
FYFY 2011
Main Implementing EntityMitsubishi Research Institute, Inc.
FS PartnerThe contractor, Mitsubishi Research Institute Inc. has solicited the cooperation of the following companies:
Nghi Son Cement Corporation, Vietnam National Cement Association (VNCA), Vietnam Institute for Building Materials(VIBM), Nippon Steel Corporation, JFE Steel Corporation, Kobe Steel Group, Sumitomo Metal Industries, Ltd, Nisshin Steel Co. Ltd, Taiheiyo Cement Co. Ltd.
Location of Project ActivityViet Nam
Category of Project ActivityOthers
Summary of FS ReportPDF (544KB)
Description of Project/ ActivityExport of Ground Granulated Blast Furnace Slag (GGBFS) to Vietnam, to be blended with cement clinkers to produce GGBFS blended cement.
Reference Scenario and Project/ Activity BoundaryTo be selected from the following:
    A: No change in existing facility (substitute cement in the market)
    B: Will use other blending material
    C: Will construct a new clinker production line
    D: No change in existing facility (substitute cement of existing facility)
Monitoring Methods and PlanFor scenarios A and C, MRV methodology incorporates various default factors so that consumption data of GGBFS alone will yield emission reduction.
For scenario B, the MRV methodology is not applicable.
For scenario D, the data of the project site is usable according to the provisions of ACM0005.
GHG Emissions and ReductionsBase case: 396,505tCO2 (according to sensitivity analysis, expected to yield more than 350,000tCO2 in most cases)
MRV System for GHG ReductionsA simplified MRV methodology is developed, whereby GHG reduction can be calculated by minimal monitoring (by consumption of GGBFS)
Analysis of Environmental, Socioeconomic and other Impacts (including Securement of Environmental Integrity)Limited positive and negative impact besides considerable GHG reduction and energy / resource conservation.
However, the project is expected to contribute to SO2 reduction.
Financial PlanningTotal cost is expected to be about 4 billion JPY.
Introduction of Japanese TechnologyJapanese technology on slag grinding and mixing is expected to be technologically superior, though high cost is a possible problem.
GGBFS itself is a Japanese product, and is considered to possess superior quality.
(i.e. Improvement of Local Environmental Problems)
Considerable energy conservation results in reduction of SO2. The project will also contribute to conservation of materials such as limestone.
Contribution to Sustainable Development in Host CountryGGBFS blended cement, with its high resistance against sulfuric acid, is expected to suit the needs of infrastructure development in Vietnam. Furthermore, GGBFS blended cement emits less heat during hardening, which makes it suitable for use in massive quantities often required for infrastructure projects.
