TAILIEUCHUNG - DEVELOPMENT OF STANDARDS OF AOX FOR SMALL SCALE PULP AND PAPER MILLS

The semichemical process SAICA (Lora & Escudero 2000) and chemi- mechanical Bivis process (Westenbroek & van Roekel 1996, Roberts 2000, Westenbroek 2004) have also been used for mill-scale non-wood pulp production. The chemical consumption of these processes is lower than in chemical processes, nevertheless the spent liquor must be incinerated or treated biologically. Some mills in China have used the neutral sulphite semichemical (NSSC) process (Nassar 2004, Savcor Indufor 2006, Pöyry 2006) for containerboard production. Environmental issues are a problem with this process as well. . | PROGRAMME OBJECTIVE SERIES PROBES 104 2006-2007 DEVELOPMENT OF STANDARDS OF AOX FOR SMALL SCALE PULP AND PAPER MILLS CENTRAL POLLUTION CONTROL BOARD Ministry of Environment Forests Govt of India Parivesh Bhawan East Arjun Nagar Delhi- 110 032 Website e-mail cpcb@ Pra -OT HT7 ì r cf R ẽH TTTCh Mi í HU xyq 7TH H5ĩĩẽrq ŨL HÌ.

MAUSKAR IAS Chairman Central Pollution Control Board A Govt of India Organisation Ministry of Environment Forests Phone 22304948 22307233 FOREWORD Generation of toxic organo-chloro-compounds IS a serious issue in small pulp paper industries due to use of molecular chlorine and chlorine based bleaching chemicals. These small pulp paper mills are unable to go for cleaner technologies basically due to its higher cost. At present there is no legislative control for AOX generation for this category of pulp paper industries. In view of these facts .therefore. Central Pollution Control Board CPCB has taken-up the project to develop standards for Adsorbable Organic Halides AOX and entrusted the project to Central Pulp Paper Research Institute CPPRI Saharanpur. The in-depth studies in selected small pulp paper industries and preparation of basic document in development of standards in pulp paper industries were accordingly carried-out by CPPRI. Shri . SEE. Sh. . Gupta EE and Mrs. Hima Jwala SRF have co-ordinated project activites and prepared the present Report under the guidance of Sh. . Ansari Additional Director and Dr. B. Sengupta. Member Secretary of Central Pollution Control Board. I trust the document will be useful to all those interested in pollution control in the pulp paper industry. .
