Executive Summary
The future of humankind depends very much on our ability to change our lifestyles and
agree to follow a low consumption pattern of living in terms of resources taken from the
globe and return to a sustainable development path at the earliest. The opportunity
window for restoring nature to its prolonged state of hosting life forms to flourish under
its caring environs is according to scientists, very short and lasting only up to 2030.
Within this time, with the willing actions of every citizen wherever they are, coordinated
and directed actions should start and continue thereafter till a balancing stage is
reached where moderate use of resources and mitigation actions for healing the hurts
already inflicted, balance positively to a sustainable nature.
Eco campus is a concept implemented in many educational institutions, all over the
world to make them sustainable because of their mass resource utilization and waste
discharge in to the environment. PIT College believes that there is an urgent need to
address these fundamental environmental problems and reverse the trends. The
purpose of the audit was to ensure that the practices followed in the campus are in
accordance with the Green Policy adopted by the institution.
Green Auditing of a Higher Education Institution is required as a part of Criterion VII (of
the 7 criteria prescribed) under the Guidelines for Submission of the mandatory annual
Internal Quality Assurance Report (IQAR) by Accredited Institutions.
It works on the several facets of Green Campus including Water Conservation, Tree
Plantation, Waste Management, Paperless Work, and Alternative Energy. With this in
mind, the specific objectives of the audit was to evaluate the adequacy of the
management control framework of environment sustainability as well as the degree to
which the Departments are in compliance with the applicable regulations, policies and
standards.
Initially a questionnaire survey was conducted to know about the existing resources of
the campus and resource consumption pattern of the students and staff in the college.
In order to assess the quality of water and soil, water and soil samples were collected
from different locations of the college campus and analysed for its parameters.
Collected data was grouped, tabulated and analyzed. Finally a report pertaining
environmental management plan with strength, weakness and suggestion on the
environmental issue of campus is documented.

Introduction
Environmental audit or Green audit reflects evaluations that help us to identify
environmental compliance and management system, implementation gaps, along with
related corrective actions. Green audit is a useful tool to determine how and where the
most energy or water resources are being used, the type and volume of waste
generated and can then considerations be given on how to implement changes and
make savings. It can create health consciousness and promote environmental
awareness, values and ethics. Overall, it plays a vital role in imparting a better
understanding of Green impact on campus to staff and students.
Need for green audit
As environmental sustainability is becoming an increasingly important issue for the
nation, the role of higher educational institutions in relation to environmental
sustainability is more prevalent. In this context, it becomes imperative to adopt the
system of the Green Campus for the Institutes which will lead to sustainable
development. Besides, it also reduces a sizable amount of atmospheric carbon dioxide
from the environment.
Green Audit is assigned to the Criteria 7 of NAAC, National Assessment and
Accreditation Council which is a self-governing organization of India that accredits the
institution according to the scores assigned at the time of accreditation. NAAC has
made it mandatory that all Higher Educational Institutions should submit an annual
Green Audit Report. Moreover, it is part of Social Responsibility of the Higher
Educational Institutions to ensure that they contribute towards the reduction of global
warming through Carbon Footprint reduction measures.
Objectives of the audit
● Understanding the current practices of sustainability with regard to the use of
water and energy, generation of wastes, transportation,purchase of goods,
etc;

Biogas Plant
In PIT, kitchen waste is used to generate thermal energy for cooking and heating. The
bio-gas produced from food waste, decomposable organic material and kitchen waste,
consisting of methane and a little amount of carbon dioxide is an alternative fuel for
cooking gas (LPG).
The college has made proper MoU with Panimalar Medical college Hospital & Research
Institute (PMCH&RI) for generating alternative fuel from kitchen waste. Day to day
kitchen waste is send to PMCH&RI for processing, where the Kitchen waste is
processed and moistened to produce a suspension that subsequently undergoes a
fermentation process. Fermentation produces biogas – a valuable energy source – that
is desulphurised by biological means. Also, the waste materials can be disposed off
efficiently without any odour or flies and the digested slurry from the bio- gas unit can be
used as organic manure in the garden. The major components of the bio-gas plant are
a digester tank, an inlet for feeding the kitchen waste, gas holder tank, an outlet for the
digested slurry and the gas delivery system for taking out and utilizing the produced
gas.
The PMCH&RI Campus is Equipped With Bio Gas Plant to Promote the Alternate
Energy Resources Method, generated fuel is collected in cylinder which is used inside
the PIT kitchen
Eco-friendly technology allows for the production of renewable natural gas in the form
of biomethane. The facility processes about 500kg of kitchen waste every day and Gas
Volume 40cu m – mainly the contents of organic waste from College Hostels, as well as
leftover food from Campus canteens and expired food.
