At HNL, Pollution Control is an integral part of production. In tune with National priorities and social obligations, HNL has adopted a policy of reciprocating the gifts of nature.

HNL has Electro Static Precipitators (ESP) and Dust Collectors to control atmospheric pollution and to preserve the lush green vegetation of over 30,000 trees around the plant. This is no small achievement, for the United Nations Environmental Programme (UNEP) has selected HNL as the model paper mill in the Asia Pacific Region under its NIEM programme. Besides, HNL has bagged the Kerala State Pollution Control awards in 1997-98, 1999-2000 and 2002 for the best pollution control measures and processes adopted in the mill.
