A thought:

~ Ankit

We must cut down millions of trees or we wont be able to read the daily news paper;
We must destroy the ozone layer or we wont be able to use hairspray.
We must pollute the  rivers to an extent of irreparable damage or we cannot afford the luxuries.
And finally we must deny that we are doing this.

E-waste Management: IIT Bombay going green

E-waste Management: IIT Bombay going green

~Gyalpo, Shalini

IIT Bombay being a technology institute procures and disposes a huge amount of electronic items every year. The computer desktops and allied accessories, which form a major chunk, & other electronic wastes such as discarded CD-ROMs, printer cartages and so on, are being disposed-off amounting upto 1000 tons or more annually.

These electronic wastes or commonly known as e-wastes, primarily generate from the Computer Centre, the Administration section, and other Departments. The electronic equipments used in the departmental labs also add to the e-waste volumes disposed. To add on, the frequent hardware up-gradations in the market propel the departments to phase-off the older, yet in working conditions, for the latest hardware. The obsolete ones are then either accommodated in some low profile vacancies or are sold to IITB’s staff members. However, the cascading up-gradation effect, ultimately leads the obsolete products to the disposal in the form of e-waste.    

With the growing concern about the hazards of e-Wastes, The Earth Club has taken up the task of identifying a safe disposal channel and put-in place a disposal mechanism, so as to ensure an environmentally friendly and safe exit of the harmful e-wastes from the campus.

As of now IIT Bombay doesn’t have any policy regulations for the disposal of e-waste as such. All kinds of wastes, irrespective of its salvage value or impact on environment are sold or written off through the same channel of the Central Stores, which is finally tendered to some traditional scrap vendors, with no credibility and expertise of handling e-wastes.

Therefore, the club is working towards setting up a safe disposal mechanism, which will ensure the involvement of only the certified e-waste recyclers, with prerequisite infrastructure for the safe electronic disposal.

In this regards, a new E-waste policy report has already been framed by the club, in consultation with the institute authorities like the Computer Centre, Estate Office, Departments, Hostel Control Unit, and Central Stores. The Electronic-waste policy drafted by The Earth Club, IITB members, has already been submitted to the Director’s office, and expected to be passed by the month end; following which, a pilot project will be carried out to study the operational feasibility and economic viability of the E-waste disposal process by the Club.

Biogas – Fuel for Food

~Ankit Mittal with Inputs from Samarth Kudalkar

The privatization of the hostel mess facilities has definitely started delivering on its promises in terms of freedom of choice to the students, ease of management to the institute authorities or better deals to the mess contractors. Apart from these, earth club has observed a sublime benefit of the privatization of messes, in the students’ community.

It has not only granted them the freedom of choice, but also the realization of responsibility.

And the students have received them very well by thinking & acting about the mess issues like hygiene, accountability and transparency. One of such major students’ concerns is to reduce the monthly mess bills by employing Biomass plants in hostels.

Currently Hostel-7 has taken up the task to set up a Biogas plant which would utilize the kitchen waste to produce Biogas and replace the LPG as the cooking fuel, thereby saving the expenses on the cooking fuel.

In this regard, a company providing waste management solutions was consulted. They have designed a Biogas plant which uses waste food and other bio-degradable wastes as feedstock to produce Biogas. On a rough estimate a 40 m3 plant consuming 200 kg of waste per day would produce biogas that would be sufficient to replace 17 kg of equivalent LPG per day. The biogas produced will be sold to the private contractor of the Hostel Mess to recover the initial capital cost incurred. The cost of the plant will be approx. Rs. 500,000. Therefore the payback period will be around 2 years since its installation. (Price of LPG used per day-Rs 800/- approx).

The H-7 students have identified couple of challenges that could impinge this project & one of most prominent is handling the slurry—the left over—generated during the biogas generation process. One solution could be, since the slurry contains high amount of NPK, it can be used as a fertilizer. Also the current stoves have to be studied for their compatibility with the biogas fuel. The availability of water can be yet another issue since the Biomass process requires a large amount of water to the tune of almost 12 liters per kg waste.
