| CLEANER
PRODUCTION OPTIONS FOR PULP AND PAPER INDUSTRY |
ACTIVITIES FOR FUTURE :
Sincere
efforts should be made in future to make cleaner production the production culture
not only in the pulp and paper mills but in other industries as well. In India,
the other industrial sectors, such as sugar, textile and tannery, are also facing
considerable problems related to pollution. It is necessary that the UNEP should
take up these industrial sectors on priority for implementation of cleaner production
concepts in India and other NIEM participating countries. However, some of the
cleaner production measures require huge funds for implementation and, therefore,
for implementing such CP options, assistance in the form of grant of soft loan
through agencies like the Asian Development Bank, the World Bank among others
will further serve the cause of cleaner production in industries and environmental
protection.
