Abstract— The high generation rate of medical
waste is a proof that medical waste management is
problematic. Base on a case study undertaken at
different health institutes. This research looks in to
the various issues in the field of medical waste
management. The research explores the staff’s
perception towards the medical waste management.
The study aims to examine the knowledge level and
attitude and role of health care workers towards the
medical waste management.
Here we study quality index and environmental index
of two health care centres one is private hospital and
another one is government hospital and compare
these two indexes in respect to each other by
questionnaire survey.
To produce a more environmental friendly services,
the customers, and environmental criteria must be
taken into account during the decision making
process, and the Green Quality Function Deployment
(G-QFD) provides a very useful methodology to fulfill
this objective.
Keywords— waste management, G-QFD.
I. INTRODUCTION
The main objective of the eco-design is to create
services for a sustainable society that will not only
reduce the impact on the environment, but also,
take into account the expectations of the customer
and the economic reality of the services. From this
perspective, the Green-QFD methodology is a
useful technique for that, not only from traditional
viewpoints regarding costs or customers, but also
from the environmental perspectives Definition and
Classification of Medical Waste
All the wastes generated by medical activities come
under Health-care waste. They are involved in
diagnostic activities and preventive, curative and
palliative treatments.
There are two types of health care waste:
1) Hazardous waste
Clinical/Infectious/medical waste, cytotoxic and
cytostatic medicines, batteries, health are chemicals
and hazardous properties, radioactive substances, X
ray photo chemicals.
2) Non- Hazardous waste.
ISSN: 2231-5381
Offensive / hygiene waste, non cyto-toxic and cytostatic medicines, domestic waste, packaging waste,
recyclable waste food waste.
II. LITERATURE REVIEW
Different versions of the Green-QFD help to select
the best alternative services taking into account the
environmental, customer and cost requirements.
Cristofari et al. (1996) combines Quality Function
Deployment (QFD) and Green-QFD, Mehta and
Wang (2001) utilizes the Eco- Indicator’99 method
(Goedkoop and Spriensma, 1999) for quantifying
the environmental impact of the product in GreenQFD III. Finally, Dong et al. (2002) includes fuzzy
multi-attribute utility theory to estimate the life
cycle cost in Green- QFD IV.
III. METHODOLOGY
From each independent viewpoint, each alternative
receives punctuation. In order to obtain the best
conceptual design that integrates all these criteria
simultaneously, selection of the best conceptual
design.
A. Steps of methodology
1) Selection of two hospitals, hospital A [private]
and hospital B [government].
2) Identification of medical waste
3) Preparation of questionnaire for survey In
hospital A and hospital B.
4) Data collection, in this study we select group of
50 peoples (patient) and there attenders from
hospital A and B.
And after doing survey from these peoples we
frame quality house of A and B.
5) Development of quality house for hospital A and
B from the customer demand and questionnaire
Economical, hospital transportation, hygiene of
hospital, qualification of doctors, attitude of
hospital staff, location of hospital, advance
technology.

VI. CONCLUSION
On studying various aspects of customer
demand and environmental factor in hospital
A and hospital B through green QFD it is
concluded that quality and waste management
system is better in hospital A than hospital B.
Suggestions for improvement in quality and
waste management system in hospital B are:
1) Recruitment of specialist doctors and skilled
paramedical staff.
2) Need of more conscious regarding waste
management system by using advance and
safe method.
