INTRODUCTION
Background
St. Aloysius College, Elthuruth, is a first grade college affiliated to the University of
Calicut. The journey of St. Aloysius began on 1 June 1968 with a vision and mission of St.
Chavara Kuriakose Elias “to mould intellectually competent, morally upright, socially
committed and spiritually inspired individuals”. Starting with Pre-degree courses in 1968, St.
Aloysius had its first extension with the laying of foundation stone by late Rev. Dr. Clemens,
then Provincial and later Bishop of Sagar. It is run by Fathers who belong to the congregation of
Carmelites of Mary Immaculate (CMI) founded by St. Chavara Kuriakose Elias.
Today, the college has 16 UG and 8 PG courses along with English as Research Centre. The
campus has strength of 2004 students and 105 teaching faculty. The campus includes a Main
Block, Jubilee Block, Canteen, Bishop Clemens Block, C-Block, a Central Library, Auditorium,
Laboratories and Computer Labs. The college also has Women’s Hostel off the campus with 70
students residing in it. The major water source is wells. Electricity power needs for the entire
campus is met through On-grid solar power supported by KSEB and generators.
The motto of the college reveals the telling vision the pioneers had in establishing this
institution. The College motto, Sursum Corda, ‘Lift up Your Hearts’ is built on an analogous
phrase in the Bible, ‘lift up the soul’.

Green Audit
Green audit is the process of assessing the environmental impact of an organization, process,
project, product etc. Green Audit can be defined as a basic management tool comprising a
systematic, documented, periodic and objective evaluation of how well environmental
organisations, management systems and equipment are performing. The aim of the audit is to
facilitate management control on environmental practices and to enable the organization to
assess compliance with its policies including meeting regulatory requirement.
Methodology
Key components of Green audit conducted at St. Aloysius College, Elthuruth included:
i. Pre-audit planning
a) Preliminary literature review of concepts and methodologies related to green audit.
b) Discussion with the management staff on various systems installed in the campus.
c) Awareness creation and interaction with the staff and student on the concept of green audit.
d) Walk through the entire campus to understand the nature of water use, energy use and waste
management systems in the campus.
Fig 1.2 Green audit inauguration at St. Aloysius College, Elthuruth
A green audit was started at St. Aloysius College, Elthuruth by SCMS Water Institute (SWI),
SCMS School of Engineering and Technology, Karukutty. The pre- auditing function was
inaugurated by Ms. Mary Thomas, President, Thrissur District Panchayath on 20th
June 2018.
ii. Data collection
a) Development of questionnaire format to identify all water/energy using fixtures/ equipment
and examine water or energy use patterns for individual buildings in the campus.
b) Collection of secondary data from compilation of electricity bills, collecting records of
pumps, generators, water quality analysis reports, civil and electrical drawings etc.
c) Semi-structured interview with maintenance manager, technicians, plumber and housekeeping
staff on current situation and the past trends in water consumption, electricity consumption,
waste management, waste generation etc.
iii. Data Processing and analysis
The existing trends and patterns in water usage, energy usage and waste generation and
management is analysed in this step from the data collected from the previous step.
iv. Audit Recommendations and reporting:
Based on the understanding from the green audit, recommendations are given to improve the
existing environmental performance of the campus and are documented in a report format.
WATER AUDIT
A water audit is a systematic review of a site to identify opportunities to improve its water use
efficiency. The site may be a public water utility, facility (institutional or commercial properties
like malls, office, schools etc.) or a household. Audit recommendations are developed based on
surveys and assessments of water-using hardware, fixtures, equipment, landscaping, and
management practices at the site. Water audit involves tracking, assessing and validating all
components of flow from the site of withdrawal or treatment through the water distribution
system and into the consumer’s properties. Water auditing examines the major areas of water
use, including human consumption, personal hygiene & sanitation, washing, cleaning, laundry,
gardening etc. Water auditing is an on-going process and rarely stays consistent in a site or
system over time. Therefore, in order to gauge progress from adopted water conservation and
cutbacks, water audit should be performed on a regular basis. In addition, it provides convincing
overview of the water use trends, effectiveness of conservation measures and potential cost and
water savings.
Water supply
Around 32.658 kilo litres of water is used in the campus daily. Source of water for the entire
campus is wells. There are two wells in the campus. The well next to the main block provides
water supply to the main block, as well as the canteen and the Maths block. The well next to the
Jubilee block provides water to Jubilee block. The girl’s hostel has a separate well to meet its
water supply. Moreover, around 2000 litres of mineral water is used daily for drinking purpose
in the academic blocks.
The college has a well recharging system, using this system rainwater from roof tops is
recharged into the well after filtration (figure 2.1). Table 2.1 shows the characteristics of water
from the well of the campus.

The various blocks of St. Aloysius campus such as main block, Jubilee block, C- Block, canteen,
Bishop Clemens block and auditorium were surveyed in this study with the questionnaire
developed based on literature review and observations and discussions during the pre-audit
phase (Annexure 1). Figure 2.5 shows the water usage by various activities of St. Aloysius
campus based on the survey (figures 2.2, 2.3 and 2.4). It can be seen that toilet flushing (55%),
wash basin (19%),
washing clothes (10%) and drinking (6%) are the activities that dominates water usage. Figure
2.6 shows the water consumption by different blocks of the campus. Leakages of taps were
found in the ladies hostel.

2.3 Water Circuit Diagram
Water circuit diagram shows how the water flows from the source to the consumers. Based on
the walk through surveys, discussions with staff and managing committee a water circuit
diagram was prepared as shown in Figure 2.7. Source of water is two wells. The water from the
well next to the main block is pumped to two tanks placed above the main block that have
capacities 20000 litres and 2000 litres. These tanks supply water to the canteen, main block, and
maths block.
The water from the well next to the Jubilee block is pumped and sent to two tanks placed above
the Jubilee block that have capacities of 5000 litres and 20000 litres (figure 2.8). From the 5000
litres tank, 2000 litres of water is sent to a reverse osmosis (RO) type water purifier having a
capacity of 500L/H (figure 2.9). The water after purification is used for drinking purposes. The
rest of the water from the tanks is sent to bathrooms.

ENERGY AUDIT
An energy audit is an inspection, survey and analysis of energy flow for energy conservation in
a building, process or system to reduce the amount of energy input into the system without
negatively affecting the output. Reducing energy consumption while maintaining or improving
human comfort, health and safety are of primary concern. The primary objective of energy audit
is to determine ways to reduce energy consumption per unit of product output or to lower
operating cost. Energy audit provides a "benchmark"(Reference point) for managing energy in
the organization and also provides the basis for planning a more effective use of energy
throughout the organization.
General description about energy consuming appurtenances /activities in
the campus
Basically there is a Main block, Bishop Clements block, C - Block & an Auditorium cum
canteen block incorporating Jubilee Block, various science laboratories, library, computer labs,

SOLID WASTE AUDIT
Scope of Waste Audit
Waste audit encompasses the entire spectrum of waste collection, segregation, reuse,
recycle and landfill. Appropriate suggestions and justifications would be put forth to improve
the efficiency of the system as a whole.
Waste Generation in the Campus
Waste generated in the campus varies from paper, plastic, cloth, glass, food, and sanitary items.
Their sources include academic blocks, hostels, office, canteen and kitchen. The waste that is
generated from all these sources if not handled properly may pose a serious health and
environmental hazards. The wastes generated from various activities in the campus are
mentioned below.
CANTEEN
Food waste of 15 kg is generated daily from the college canteen, which is taken to a
vermicompost plant. Other wastes including paper, plastic, ice cream cups etc are generated
daily.
MAIN BLOCK AND ACADEMIC BLOCKS
2 kg of paper waste and 1 kg of plastic waste is being produced daily. It is collected weekly.
The plastic waste, which includes items like plastic bottles, are given to the municipality
waste collection units. Mixed paper wastes including answer sheets, question papers, office
papers, used notebooks, packaging wastes etc. are collected, sorted and given to waste
collection units.
HOSTELS
Wastes including paper, plastic, sanitary items, bags etc. weighing around 6 kg are collected
daily and burned. Food waste from the hostel weighing around 2 kg are buried in pits.
E-WASTE
E-waste generated in the campus, which is around 209 kg per year, is stored in a room and
given to E- waste scrap dealers.
Methodology
St. Aloysius campus includes a main block, Jubilee block, laboratories, Bishop Clemens block
and a canteen. To evaluate the trends of waste generation and waste management techniques
adopted at campus, interviews were conducted with the cleaning staffs, main officers and
students. The amount of waste generated, major sources of waste and frequency of waste
collection were enquired from the cleaning staffs. The details about the sources of waste
generation in the campus are shown in Table 4.1.

The St. Aloysius campus serves as a living laboratory of sustainable practices by
integrating academia, student life and campus operations, researching new solutions through
campus practices for sustainable waste management. Students have played a vital role in
encouraging environmental consideration in every functional facet of the institution. An
efficient management of waste starts with regular collection of waste generated. This task has
been made easier by placement of dustbins at appropriate places. Dustbins are placed at
canteens, each corridor of all the buildings, etc. Campus wastes dominantly paper, plastic,
thermocol, sanitary, ceramic, etc. which can neither be reused nor recycled and other
combustible wastes from each building are collected by the cleaning staffs of the campus and
burnt in an incinerator.
The St. Aloysius campus is now making a conscious effort to establish the campus as a ‘zero
waste’ zone, through a slew of scientific and environment-friendly measures. A number of
initiatives have been put in place to promote the concept of ‘reduce, reuse and recycle’ and
contribute mite to protecting the environment.
Fig 4.2 Data collection by students for understanding waste management in St. Aloysius
campus
A) Management of Paper Waste
Papers are segregated based on the following basic paper grade categories:
Magazines
Mixed Paper
Old Newspapers
Carton
Mixed paper is a broad category that often includes items such as discarded mail, telephone
books, paperboard and catalogues. High grade deinked paper is made of high grade paper such
as letterhead, copier paper, envelopes, and printer and convertor scrap that has gone through the
printing process.
B) Management of Food Waste.
Food wastes and all other organic wastes from canteen are taken to a vermicomposting
plant (figure 4.3). The food waste from the hostel is buried in a pit. The amount of organic
matter being retained at the campus is nil.

C) Management of Combustible Waste
An incinerator is installed at the campus in which the combustible wastes like paper,
plastic, wrappers, gunny bags, paper bags, clothes, sanitary waste etc. are burnt in an incinerator
(figure 4.4). The ashes and residues from the incinerator are removed and used for gardening.
No fuel is used for burning the waste.

D) Management of Recyclable Waste
Wastes including plastic bottles, glass bottles etc. are collected and given to the
municipal waste collection units. E-wastes from the campus like monitors, keyboards, mouse,
motherboard, hard discs, switch ports, UPS, CD’s, LCD projectors, printers, battery etc. are
presently stored in a room in the main block (figure 4.5) and given to E-waste scrap dealers.

SUMMARY OF FINDINGS AND RECOMMENDATIONS
Audit recommendations for potential water saving
Based on the information collected and observations, the following can be recommended to
reduce water use and increase its efficiency
Control quantity of water in Flush cistern in toilets: Currently the college is using flush
cistern toilets. Buckets are also used to collect water. It is observed that there is no
proper control over the quantity of water being used per use. Hence, it is suggested to
regulate the quantity of water in flushing cisterns in all the toilets to regulate
consumption of water.
Establish a water budget for the building and monitor performance criteria in due course
of time.
Install sensors to avoid the overflow from overhead tanks.
Awareness to the students and staff regarding the importance of conservation of water.
Incentives for those who consumes less water in the hostel.
The waste water is reuse it for gardening and agriculture.
Expand the present well recharging system to collect rainwater from all rooftops.
Audit recommendations for potential Energy saving
All air conditioned rooms can be provided with doors having automatic closing
mechanism and windows with tinted glass to reduce load on the air conditioning system.
Currently most of the classrooms are having window curtains. Avoid using curtains to
facilitate entry of sunlight and to avoid the use of tube lights and minimize the use of
ceiling fans at high speed.
It is recommended that tube lights may be replaced with CFL or LED light at the end of
utility period of currently installed tube lights as it consumes much less energy compared
to fluorescent lamps.
Use air conditioners only during summer.
Switch off the printers at the main outlet itself when not in use or in other words machine
should not be kept in stand by and sleep mode which consumes power.
Reduce wastage of water and thereby the power required to pump up the water can be cut
down.
Switch off the fridge at peak hours rather than working it for 24hrs daily.
Make sure the chargers are unplugged after charging, continues charging even after full
charge consume more energy.
Audit recommendations for waste reduction
Maximum reduction of burning waste materials is required by adopting recycling
methods.
The organic waste produced is currently sent to a vermicompost plant. As an add-on,
biogas plant can be utilised to decompose organic waste. This will not only decompose
the waste, but will also provide biogas that can be used as fuel for cooking purposes.
The used water from laboratories is disposed in proper method without making
environment pollution.
Hazardous and toxic waste generated from laboratories should be stored separately and
handled as per the standard rules.
Provide more dustbins in gardens, corridors, roadsides, and canteen and make students
more aware of using it effectively.
Sell waste paper, plastic waste and E-waste to recycling companies other than burning.
A number of initiatives to be put forward, to promote the concept of ‘reduce, reuse and
recycle’ and to make the campus a 'zero waste' zone.
