The Saigon-Hanoi Beer Joint Stock Company based in Tu Liem Industrial Park for Small and Medium Enterprises, unlike other beer companies, does not suffer from the typical smell of brewer's yeast. The company is surrounded by green trees and an energy-efficient lighting system. The road leading to the company looks very clean. Nguyen Van Bien, the company's deputy director in charge of technical management, said, "The company has paid great attention to applying modern technology in production and improving worker awareness of the need to save input materials in order to reduce production costs and enhance competitiveness."
The company has taken the initiative in applying energy conservation methods and using modern equipment to reduce material and fuel consumption. In the past, it used water to clean the floor, but now the company has made a shift to dry cleaning, which helps it save water. An inverter has been installed on all kinds of electrical equipment to reduce power consumption. The houblon boiler consumes much electricity and water during the beer production process. The company has bought a set of heating equipment to make use of the steam that comes from the houblon boiler to generate heat, which allows the company to save a considerable amount of fuel oil. Instead of building a separate water supply system for the steamer, the company makes use of the steam that comes out during the production process to provide water for the steamer. Doing this way, it can reduce water consumption.
Regarding the company's wastewater treatment system, Nguyen Van Bien said, "Before it is treated, wastewater will undergo the anaerobic fermentation process and create gas. The Saigon-Hanoi Beer Joint Stock Company makes use of this gas to fuel the steamer and generate steam for heating the boiler and cleaning cans and bottles. The amount of gas created by wastewater during the anaerobic fermentation process is sufficient for the steamer to operate 24 hours a day, which can replace about 10 percent of the required amount of coal and fuel oil. The utilization of waste gas also helps prevent environmental pollution. All trees around the wastewater treatment system of the company grow well."
Investment in the wastewater treatment system accounts for 10 percent of total investment in the company's brewery. Nguyen Van Bien said, "Although this was a costly investment, it allows us to create a safe working environment for our employees, promoting the company's long-term development and increasing its reputation."
In the past, the company used high-pressure lamps which consumed large amounts of electricity. When power supply was resumed after a sudden cut-off, it took the lamps about 15 minutes to provide proper light again, interrupting production. In response, the company has replaced all high-pressure lamps with T8 compact lamps to save about 10 percent of power consumption. All the outdoor lamps have been replaced with headlamps which consume only about 20 percent of the amount of electricity consumed by the old lamps.
These solutions have helped the Saigon-Hanoi Beer Joint Stock Company to reduce power, fuel oil and water consumption by 10 percent. Specifically, fuel oil consumption has decreased from 33kg per 1,000 liters of beer to about 30.05kg, power consumption from 110kW to 108kW, water consumption from 6.2cu.m to 5.1cu.m. These solutions have allowed the company to save several hundred million dong each year. "In the future, the company will continue to research and apply new methods to save more energy, reduce production costs and increase its reputation on the market," Nguyen Van Bien said./.
