Vertical Shaft Brick Kiln Project: • A Case Study • Workshop on • CDM: Opportunities in RajasthanJaipur 28-29 January, 2005
CONSTRUCTION SECTOR IS THE LARGEST CONTRIBUTOR TO CO2 EMISSIONS IN INDIA
60% of CO2 Emissions in Construction Sector are contributed by • Cement • Steel • Bricks
Demand Projections of Building Materials Building material demand Cement (mt) Brick billion Steel (mt) Lime (mt) Year
National Concern Majority of current technologies for burnt bricks do not meet environmental standards orSupreme Court of India directives
CDM Project • Technology and Action for Rural Advancement will facilitate installation of 100 VSBKs across 3 states • TARA will provide the technology and existing kiln owners the finance
CDM Project - Vertical Shaft Brick Kiln Technology Description Multiple Shaft VSBK with individual shafts upto 1.25m X 2m size Operation Continuous mode Production Capacity 10000 to 40,000 per day Fuel Pulverized coal, lignite pellets Greenhouse Gas Mitigation Drastic reduction in fossil fuel use (upto 60%)
Baseline • Movable Chimney Bull Trench Kilns banned by the Supreme Court • Fixed Chimney BTK is an option but involves higher capital investments • Most MCBTKs still operating due to less enforcement and lack of alternative options • Continuation with MCBTKs is therefore the baseline scenario
Energy Consumption in Brick Production Clamps = 4.5 to 8.0 MJ / Brick Movable Chimney = 4.2 MJ / Brick(BTK) VSBK = 1.80 MJ/ Brick
Baseline Calculations Energy baseline: • Specific Energy Consumption using MCBTK = 4.4 * 10-6 Tj/ brick • Total Number of bricks produced in 70 kilns = 70 kilns * 20,00,000 bricks/ kiln = 140,000,000 • Total Energy Consumption = Specific Energy Consumption * Total Bricks produced = 4.4 * 10-6 * 140,000,000 = 616 Tj • Carbon Emission Factor (CEF) for bituminous coal = 25.8 tonnes of carbon per Terajoule Emissions baseline= Total Energy Consumption * CEF = 616 Tj * 25.8 t C/ Tj = 15892.8 t C
Additionality • Identification of alternatives • Continue their existing operation with MCBTKs (not legal) • Replace MCBTKs by Clamp Kilns (not profitable) • Replace MCBTKs by Fixed Chimney BTKs • Replace MCBTKs by VSBK.
Additionality • Investment Analysis • IRR for Fixed Chimney BTK: 34% • IRR for VSBK: 24%
Additionality • Barrier Analysis • Investment Barrier : Existing kiln owners used to cash requirements of Rs. 20 lakh per annum.In VSBK double is required • Technological Barrier • Reluctance to adopt a new technology • Service infrastructure not yet in place • Require more trained manpower
Additionality • Impact of CDM Registration • Increases IRR for entrepreneues to 29% • Bridges the financing gap for TARA to undertake the project • Helps alleviating other barriers
