Acts prescribes limits on the emission and stack height and in addition to it covers noise pollution with it .Various countries have different values . We would cover Indian Standards.

Bigger plants with more than two or three production line of Bread or Biscuit ovens with six or seven zones can emit considerable amount of flue gases which consists of carbon monoxides, Sulphur Oxides ,Nitrogen oxides which are dangerous for health and if not monitored can result in polluting neighbourhood .

Finally UB ( United Biscuits ) ,UK has bought a SSFI unit in Himachal Pradesh to launch its product in India . Earlier in my blog I have reported news on United Biscuits moving into India and launching its product . It has been busy with building a team and time has come to translate into manufacturing .UB has got popular brands like McVities Hoola Hoops and Jacobs Cream Cracker .
United biscuit would test launch its product from this facility in first quarter of 2010 . The brands it would go in for world famous Digestive biscuit McVities . The Indian operations is headed by Jayant Kapare . For last year it has been scouting for manufacturing unit and now its has finally taken oven this biscuit manufacturing plant in Himachal Pradesh .
UB would have to face tough competition from already entrenched players like Britannia , Parle and ITC . UB has to work it out a recipe compatible with Indian taste and to market aggressively for brand recall.As history shows that Foreign brands could not make much headway in Indian biscuit market .
Product like Britannia Digestive , Marie Gold , Nutri Choice and ITC s Marie lite would give to tough competition . Indian biscuit market is worth Rs 6000.00 crore and fiercely competitive with dozens of local players apart from the BIG 3 ,namely Cremica , Priya gold , Dukes and Bisk farm.It would be interesting to see how Indian players respond to UB s McVities.

United Biscuits is owned by private global investment firm Blackstone and European private equity firm PAI .
