Environment waste management
Gaining momentum
Pharmaceutical companies world-over
show resistance when the topic of
environment waste management comes
up. This is mostly due to the unfamiliarity
of the terrain and also because of
the inability to demark an appropriate
section, which can assume responsibility
towards environment waste management.
However, the good news is that this
perspective is slowly and steadily changing
and Indian companies are now matching
pace with the rest of the world. Read on
as Jayata Sharma takes an account of
how companies today are consciously
working towards maintaining a safe level
