Farmed Trees Concept
Studies have been conducted to find a special tree that best suits the bounty soil of Thailand. Fortunately, with intensive research efforts, a fast growing tree was developed. The advancement does not only benefit the company but at the same time promotes economic sustainability by providing extra income to almost 1,000,000 farmers in Thailand. These trees can be correspondingly planted with other agricultural products such as rice, cassava, and tapioca. The company gets its raw materials from these Farmed Trees unlike other paper manufacturers who deliberately exploit the natural forest.
Own Constructed Reservoir
Double A has its own constructed reservoir called "Emerald Lake". The company collects surplus water from the year round rainfall. It started its construction in 1991 and was subsequently finished for operation in 1995. The company spent 400 million bath for the construction of this gargantuan project. The reservoir measures 1,920,000 square meters and has a capacity of 36 million cubic meters.
Modern Water Treatment System
Double A uses state of the art biological treatment system called the “bacteria digestion process” in treating contaminated water. The process is said to be compatible with Scandinavian standards.
- • Preliminary process: First, foreign materials (such as wood pieces) from the waste water is removed using a golden sieve. Second, the filtered water is put into a mixing pond to adjust the alkaline content (fit for bacteria operation and pulp precipitation). Lastly, the temperature is adjusted and Urea Phosphate is added (a special compound which increases the efficiency of bacteria to digest contaminated water).
- • The filtered water from the first process is delivered to an air accumulation pond wherein the oxygen content is increased. It will then digest all the contaminated substances and exhNLst it. Lastly, dregs are separated through the sediment tanks, and thus produce clean water (with the right BOD and COD level compatible with regulated standard from the Factory BureNL) as a finished result.
Environment Friendly Water Treatment
After the treatment, it will be stored in a pond and will be used to water the factory yard. The place is equipped with mini sprinklers (12 mm-centered watering) in order to save money and consumption. In addition, the company offers water supply to all the companies in the 304 industrial zone.
Low water consumption (dry process)
The company uses a special dry process in making wood chips. It does not use the traditional practice of immersing wood to the water in order to peel off the bark.
Lowest water consumption for pulp bleaching process
With the use of modern technology, the company uses only 6-7 cubic meter per ton of pulp in its bleaching process compared to other factories who usually consumes over a hefty 60 cubic meter per ton of pulp.
Bleaching system with ECF
The Company uses the latest bleaching process that is Elementary Chlorine Free (ECF). The method is said to be Chlorine gas free and does not produce dioxin which is said to be harmful to the environment.
Waste Utilization
tWood bark, chips, used water with Lignin, and sludge is utilized as fuel to produce steam/energy. The produced electricity is supplied through the Electricity Generating NLthority of Thailand under the Small Power Producing project (SPP). Likewise, the Carbon Dioxide from the Power and Recovery Plant is transformed into PCC or Precipitated Calcium Carbonate which is used as an ingredient in producing quality (bright) paper.
Recycling system for chemical substances
In order to generate electricity from the used water, reagents from the previous processes are recycled. Likewise, Calcium Carbonate is added and used (produces limestone) to the reaction.
Quality of Air
The foul smell produced during the boiling process is eliminated by immersing limestone in the recovery boiler. Likewise, Pulp Mill 2 uses a burning process called "Quench System" wherein the smoke is transformed into Methanol (a kind of fuel). In case the Quench System is not available, the company uses the "Flare System" as an alternative option. In addition, the "Electro Static Precipitator" (ESP) decimates 99% of the dust and provides efficient 24 hour operation.
Quality of Noise
The noise produced in the Wood Chip Plant (60 decibels) is lower than the normal rate set by the Industrial Ministry. With this, the site is said to be employee/community friendly.
