15. CONCLUSION
• Safe and effective management of bio-medical waste is
not only a legal necessity but also a Social
Responsibility.
• Bio-Medical Waste Management cannot successfully
be implemented without the willingness, devotion,
self-motivation, cooperation and participation of all
sections of employees of any health care establishment.
• If we want to protect our environment and health of the
community we must see ourselves to this important
issue not only in the interest of health managers but
also in the interest of community.
