Study Report

Note: JCM proposed methodology, and calculation sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM.
Description of Project/ActivityThis project implements significant GHG reduction for furnaces at glass manufacturing factory which consume exceedingly much energy by introducing energy efficiency technology such as combustion control system which optimizes air capacity, and decreasing fuel and electricity consumption. The diffusion of the implementing technology in Asian countries including the host country is not yet sufficient, this project is hopefully an opportunity to come into wide use all over the Asian countries.
JCM MethodologyEligibility CriteriaCriterion 1 All of core technologies and two or more of the following other technologies are introduced in implementing the project.
- Core technologies: Automatic fuel-air ratio control system, Furnace pressure control system, Glass level control system
- Other technologies: Tertiary air inflow prevention burner, Cullet preheating system, Electric boosting system, Rapid heating system, Plant engineering (design, supervise of construction, maintenance) by companies with high technologies
Criterion 2 The applicable furnace include manufacturing of glass products.
Criterion 3 No drastic changes are made in manufacturing process and products before the project implementation and after the project period.
Criterion 4 Fossil fuel and grid electricity consumptions including production of products are measureable one (1) year before and after the project implementation.
Default ValuesGHG emission original unit of fossil fuel: Utilize IPCC default values
Electricity emission factors: Utilize values published by Vietnamese government
Discount rate of emission reduction: Calculate by the difference of the operating ratio of general technology and high technology. Use for calculation of emission reduction.
Calculation of Reference EmissionsAutomatic fuel-air ratio control system (herein referred as general technology) is diffused above a certain ratio in Vietnam. The reference scenario is set as it is introduced.
Monitoring Method
    ž Electricity consumption(kWh): Record the meter of each furnace every day, compare and match with receipt at the end of month
    ž Heavy oil inflow(kL): Record the value (L) of flowmeter of each furnace on ledger every day, compare and match with receipt at the end of month
    ž Production volume(t-Glass): Standard weight x cut frequency (number of revolutions of cutter) for fluorescent light. Standard weight x amount of gob for light bulb. Record these values every day on ledger, and conclude them at the end of month.

GHG Emission ReductionsEmission reduction= (Reference emission - Project emission) x Emission reduction discount rate 疝och (provisional figure: 8%)
Reference emission: 10,279 t-CO2/year
Project emission: 5,854 t-CO2/year
Reduction amount: 354 t-CO2/year
Environmental ImpactsThis project is not subject to EIA.
Air pollutant decreases as fossil fuel combustion amount declines.
Promotion of Japanese TechnologiesWhen in comparison of capability and price with technologies from abroad, Chinese is competitive being superior in price. Initial cost for Chinese facility is as half as Japanese that we need some sort of incentives in price and so on in order to promote Japanese technology.
Sustainable Development in Host CountryGlass production volume focusing on plate glass has been increasing currently in Vietnam. Further demand for extension and renovation of glass furnace is expected with current rise of architectural demand and production volume expansion of items with display. Japanese glass furnace has exceedingly high energy efficiency for technical accumulation of many years. Thus transferring these technologies contributes to the host country in decreasing energy consumption for long term and promoting and upgrading of energy efficiency technology.
Development and Deployment of Similar ProjectsMore diffusion of energy efficiency for glass furnace is expected with the sudden rise of energy price, regulation by energy efficiency policy, and extension of glass product market.
Especially Thailand, where there is regulation by energy efficiency policy and energy price is rising, is a promising market and there are in fact many energy efficiency furnace inquiries.
