Implementation plans:

- Establishment of the energy management board

- Preliminary assessment of energy consumption in the

Company

- General staff meeting and announcement of commitments

to undertake measures to reduce energy consumption.

- Sending for energy audit institution

- Assessment of the solutions and opportunities after audit

- Development of plans to implement the recommendations

made by the audit in phases and by annual and 5-year work

plans.

Assessment of baseline data

Consumption levels in 2008:

+ Coal: 422 kg of coal/ton of boiled noodles

+ Electricity: no monitoring

Consumption levels monitored daily since Feb. – May, 2009, after internal management

+ Coal: 400 - 420 kg of coal/ton of boiled noodles

+ Electricity: 69KWh/ton of boiled noodles at the boiler area

Consumption levels according to monthly sales records in May 2009

+ Coal: 430kg kg of coal/ton of boiled noodles

+ Electricity: monitoring gauge

Baseline data BEFORE IMPLEMENTATION OF THE MEASURES

+ Coal: 423 kg of coal/ton of boiled noodles

Assessment after audit

• Identification of assessment focus

– Reduction of pollution (wastewater, exhaust gas)

– Reduction of water consumption

– Reduction of energy consumption

• Installation of gauges, monitoring consumption

levels to identify baseline values

• Assessment of water consumption

• Assessment of energy consumption (electricity,

coal)

Assessment and technical recommendations

Boiler efficiency: 65%

Reasons:

+ Abundant of oxygen (15 – 16%)

+ Use of mechanical damper for air supply

Solution 1 and 2: improving boiler efficiency

+ To reduce abundant oxygen to 7 - 8% by connecting a

sensor for abundant oxygen with the variator of suction/exhaust

fans.

Expected results: increasing boiler efficiency to 80%

Measurement: installation of gauge for daily boiler efficiency
