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

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
