Never say dye

the next seven years to Rs 25 billion. A paper prepared
by the Punjab, Haryana and Delhi Chamber of Commerce
and Industry (PHDCCI) notes that due to stiff environmental regulations of the European Community (EC),
"the dyes and dyestuffs industry is being vacated by
European industry and this will increase the demand
from developing countries".

Even at the present export level, the dye industry is
responsible for several cases of severe groundwater and
soil pollution. Near the village of Bichhri in Rajasthan,
for instance, an H-acid plant has completely polluted the
region's groundwater and soil within three years of its
existence. H-acid is a dye intermediate whose manufacture was phased out in the EC some years ago.

This is significant in the Indian context as a large
part of the dye intermediates is manufactured in the
small sector, where worker welfare is generally ignored.
