If Asian companies are going to succeed as global players, they essentially have to also address a global market place in which the issue of environmental sustainability is an increasingly important one. We at SPV do incorporate environmental considerations into our business strategy and we are clearly outperforming our competitors in our industry here in Indonesia as well as all over Asia.
These two major investments the Waste Water Treatment plant expansion and the Waste Gas Treatment plant are another milestone in our endeavor to progress in environmental sustainability.
SPV had taken a decision last year to expand its current Waste Water Treatment plant with an additional tertiary step in the form of Biological Treatment expansion to meet the stringent local as well as international standards. This project entailed an investment of US$ 2.0 million and is fully commissioned in May-07.
SPV has selected world-class “Invent Hyper Classic Aeration design” which is a unique mixing & aeration system that provides excellent suspension of solids & homogenization. The new facilities with a treatment capacity of 24,000 m3 per day consist of new aeration tanks & secondary clarifier with its associated equipment along with Programmable Logic Controller based system.
The Chemical Oxygen Demand of the treated effluent will be lower than 150 mg/l and all other targets specified in the standard will be met.
Waste Gas Treatment plant is High-Tech plant, first of its kind in Asia, where the recovered gases from spinning is treated using vapor phase adsorption / desorption process to recover carbon disulphide (CS2).
The CS2 molecules are desorbed from the Activated carbon using steam as heating medium. The product CS2 is separated from steam and is pumped to storage tank, while the treated air free from pollutants is discharged to the atmosphere.
The capacity of the plant is 8000 Tons Per Annum of pure CS2 product. CS2 is captively used in viscose production process. This plant has been built with technical know-how from SPV's parent company Lenzing AG (Austria) with an investment of about US$ 12 million.
The plant has state-of-the-art safety & Distributed Control System and the commissioning trials are currently in the final phase.
