Song Lam Paper Joint Stock Company
19/02/2012
Song Lam Paper Joint Stock Company was established in 1976 with a capacity of 1,000 tons product/year. In 2008, a Kraft paper production line with capacity of 7.000 - 10.000 tons/year was put into operation. With the total labor of 150 people, the company specializes in many kinds of paper and carton for the local demand and domestic demand.
Before applying cleaner production, the company had to face the problem of waste water and air emission pollutions. The waste water derived from grinding, wiring, digesting, and washing processes contained COD content many times higher than that in Vietnamese Standard. Also, the air emission derived from coal burning at the boiler polluted the surrounding environment. To solve these problems, in 2008, the company accessed the component of Cleaner Production in Industries of Ministry of Industry and Trade.
With the support from the Nghe An Department of Industry and Trade and from Vietnam Cleaner Production Center, in 2008, the factory started to carry out the cleaner production assessment. In stage 1 (from June to September 2008), the company established the cleaner production team led by Mr. Hoang Phung - Director of the company– and other 7 members to carry out the cleaner production assessment on the whole of the production line. The assessment of the production lines, the determination of waste streams, the balance of materials and energy were worked out. Then all data collected were used for analyzing to find out the cleaner production options for each production process.
After the assessment and the determination of improving solution options, the factory conducted some house keeping options which required low cost and no cost with the total investment of 1 billion dong. In stage 2 (from October 2008), the company took the initiative in big investment solutions to thoroughly solve the environmental problems, viz. investigating 9.6 billion to make the cover for input material store(OCC), to make the cover for pulp store; Build synchronous system of pulp recovering in waste water; building coal storage, and Increasing the recovery efficiency of black liquor . These solutions brought in 1.7 billion dong profit as reducing the material and fuel consumption, environmental pollution and energy saving.
Benefits brought in to the company are briefly described as follows:

| Reducing 9 – 15.5% of input paper | Saving 990 million - 2.5 billion dong | |
| Reducing 13.5% of specific NaOH consumption | Saving 1.2 -1.9 billion dong | |
| Reducing 15.5% of specific alum | Saving 138 -215 million dong | |
| Reducing 16.7% specific coal consumption (2009) | Saving 656 million dong (2009) | |
| Reducing 11.7% of specific electricity consumption (in 2009) | Saving 244 million dong (2009) | |
Typical cleaner production options of the factory are briefly described as follows:
| No. | Option | Investment | Performance | CP technique |
| 1 | Replace catgut forming net by stainless forming net | 78 million dong | Saving 50 million dong Reducing halt time of machines, reducing emissions to the environment; rarely need replaced by new ones | EC |
| 2 | Replace catgut forming net by stainless forming net (in 2 recovering tanks) | 175 million dong | Saving 40kg of coal/ton of porduct | OR |
| 3 | Use smaller pipe with higher pressure | 15 million dong | Reducing 25m3/ton of product | EC |
| 4 | Maintaining pipes | 15 million dong | Reducing gas loss, reducing leaking, electricity saving | GH |
| 5 | Closing leaking points | 12 million dong | EOP | |
| 6 | Insulate cooking tank | 63 million dong | GH-EC | |

Being aware of the benefits from the cleaner production, the company decided to maintain the operation of the cleaner production team, and put the cleaner production activities into the general management system of the company. To do this, a simple environment management system was established. Also, the company made an environmental policy which stipulates the strict implementation of the Law of Environmental Protection and regulations to ensure the sustainable development and minimize the causes of waste. Besides, the company integrated the production management system and the environmental management system so that the consumption of materials and energy were controlled by monitoring the criteria in wastestreams. A system of sampling and legal procedure was also built to be applied in collecting, checking, and analyzing environmental data.
An environmental monitoring plan has been conducted. It aimes to monitor the considerable improvements brought in by the cleaner production options, and to adjust them incase some environmental benefits are reduced. The environmental monitoring system comprises air monitoring and wastewater monitoring.
Cleaner Production not only brings in benefits from energy saving, emission reduction, water consumption reduction, but also helps the company to develop production, improve product quality, and affirm the company reputation. The cleaner production options which have been implemented at the company are typical examples for kraft paper production companies in Vietnam./.
