600 pet bottles are bought and thrown all across our campus every day !

These bottles are collected and thrown in to a large concrete bins and are then burnt.

Burning plastic causes SO2 emissions and harmful gases

Leads to health problems and pollution.

Our proposal is to collect Pet bottles from the students using incentives like paying 5 rupees per 10 Bottles.

Using a granulator and washing we are going to produce Medium quality PET Flakes which can be sold for about Rs.60 per kg.

The initial investment is high but low maintenance cost and high returns by selling PET flakes we can make up cost

Collecting PET bottles from Students

Grind/ Granulate Plastic Bottles using Granulator

Float Sink Tank will lead to segregation of the heavier PET Flakes and light PVC

Segregating, removing PVC, caps and Labels

Heavier PET Flakes are washed with solar heated

water

The PET flakes are dried using the Sun

Cleaned PET flakes are then sold

5 HP granulator produces approximately 3.7 KW to 4 KW

Granulator has consumption of 100 kg per hour maximum.

Basic Assumptions by survey and observation : 600 plastic bottles per day. Each empty bottle on average 52 grams of

plastic. Rs. 60 per Kg of PET Flakes (Standard price) With 20% efficiency we have effective 120 bottles

per day.

NSI finds the need to make NITK’s campus clean and more visually appealing extremely acute - Aesthetic

To facilitate this and spread awareness regarding the collection & the segregation of waste NSI plans to give society a structured & easy to follow method of collection – Organize

Create PODs, which are basically units that focus on the collection of a particular variety of waste – Elementary

The waste collected will be converted into a simple product for everyday use – Salvage

In addition to the conventional use, the product is a green symbol – Icon

After surveying the students of NITK we found that:

Around 50% the average student’s waste produced is non-kitchen waste. This comes out to 0.3-0.4 kg of waste NSI can use - Opportunity

Inculcate a green culture in the student’s psyche, increasing the accountability and responsibility of every student associated with NSI – Inception

Every variety of waste would have its own pod; one for tetra packs, one for CDs, one for paper, etc. For example, The ChipsBag Pod – Multiplicity

Every POD is a specialized division that collects only one type of waste as explained above. This makes it easier for the members of PODs to continue carrying out their responsibility as the task is now simplified – Straightforward

The incentives for POD membership and collection include:

1. The Brand value of being a POD member, i.e. the showcase of one’s social consciousness – Fashionable

2. Free NSI products - Complimentary 3. On campus store credits (Co-op,

confectionaries, etc.) – Gratitude4. Members of PODs will have the option of designing their own product, i.e. the material used and layout of the product – Customization

The collection of the material from POD members is done by the NSI team once every week. The NSI team then delivers the material to the production team which comprises the local SHG (Self Help Group) Prakriti - Bridge

Total Outflow: Rs. 43,000Total Inflow: Rs. 70,000Profit = Rs. 27,000

The maximum waste to be collected by a member of the POD is projected by NSI to be 0.4 kg.

The above figure would mean that every POD member works at 100% efficiency, i.e. a POD member would have to make sure that all the waste of his POD type is collected.

Considering a 20% efficiency of collection and an initial number of 500 POD members, NSI projects the total amount of waste to be collected @ 280kg

Area of storage room = 3X2.5 metre

Test product: Tetra pack bag - 800 gmTherefore, 350 bags per week

Time to make one bag – 30 minutes for 3 people.

With a test group of 3 people and a work day of 8 hours: 80 bags can be produced per week

We’d need 5 groups of 3 to meet our demand of 350 bags.

CT IDEA

The NITK campus has 2 major sources of bio waste – Vegetable waste and plants

There are over 6000 students residing on the NITK campus each of who generate over 200 grams of vegetable waste in a day

NITK is a host to a variety of fauna

It has over 8000 trees ranging from teak to sandalwood to jatrophas.

Also observes abundant growth of weeds and grass

Over 10 tonnes of these plants and the leaves shed by these trees are burnt on a quarterly basis

Hence we could effectively procure over 1.2 tonnes of biomass in a day from vegetable waste

DIGESTER

The slurry is fed into the biogas unit where it is acted upon by the microbes

CONVERSION TO SLURRY

The heap of waste is mixed to a slurry.(1:1 ratio with water)

SEGREGATION OF WASTE

Removal of undesired wastes and heaping the required biomass

UTILTY

The bio gas is consumed as cooking fuel

COLLECTION OF BIOGAS

The biogas is collected after production at regular intervals

COLLECTION OF WASTE

Kitchen wastes from hostel block gathered by the mess workers

PROJECT

DESIGN

PROJECT

DESIGN

COLLECTION POINTS

The vegetable waste are collected once in two days from the mess workers. This includes 8 specific points on campus.

The waste concentration is as follows : 30 % MEGA BLOCK 15% GIRLS BLOCK 15% 3RD BLOCK 10% 5 other BLOCKS The weeds on campus are cut on a quarterly basis and heaped along with the

scattered leaves

THE WASTE  There are over 6000 students in campus contributing to approximately 1.2 tonnes

of waste in a day

FINANCIAL ASSESSMENT We require a total of 100 mini bio gas plant unit set up spanning the 8 hostel blocks

CAPITAL :Each unit costs Rs. 3500. Total set up cost including labour = 4,00,000 Tubing of Bio gas including stove = Rs2400 per initial total = 36000 OPERATIVE COST : 15 mess workers given an extra salary of Rs. 1000 a month amounting to 15000.

THE RESULT

Each unit work on 10 kg’s of biowaste to produce 8 metre cube of biogas.

Hence we obtain a total of 800 metre cube of bio gas a day

Can be used to produce 60,78,123 kcal of energy which saves 25% of the LPG demands

FINANCE

ANDSTATISTICS

BENEFITS Clean & aesthetic surroundings - Healthy

No need for dustbins in the cycle - Preventive

No change in composition of the products raw material, hence we save energy – Economical

Creation of employment for self-help groups– Fringe benefit

Revenue generated from selling this PET Flakes will sustain all required money for wages, maintenance and investments

TEAM AND ORGANIZATION

Our Campus being next to the beach and having a lot of forest area within it should be responsible for these ecosystems, and not only the authorities but even the students should take the initiative in making our Campus “greener” and “smarter”.

WHAT WE HAVE DONE?

A dedicated team of 25 members spanning all branches and all years was formed, the only common goal being to ‘engineer the change’

Faculty appreciated our idea and an organization “NITK Sustainability Initiative“ was setup to bring about the change

With the help of industry experts and mentors, we wish to implement various green initiatives on campus in the coming years.

To reduce NITK’s dependence on fossil fuels by half by the year 2020.

To become a ‘Zero Waste Campus’ by 2015.

Promote awareness on Green Living among the students in campus. Try to prevent habits which cause wastage of energy and food resources.

Promote energy conservation methods in the locality as well as nearby schools.

Be an example for local colleges in the area of sustainability.

Undertake technical projects in campus which improve energy efficiency, reduce wastage of water and reduce production of waste.
