Pune: City colleges are taking efforts to make their campuses eco-friendly through several means. College have adopted several alternatives to keep their campus free of pollution and waste.
Bio-gas at BMCC
To make the campus environment-friendly, Brihan Maharashtra College of Commerce (BMCC) has installed a biogas plant. The plant will run using food waste generated in the boys and girls hostels and canteen. Human excreta and urine will also be used to generate 100 per cent biogas. This will eliminate the need to use two commercial cylinders that are consumed daily.
The plant has the capacity to process 22.5 kg food waste every day. “Therefore, now the food waste from the hostel will not go out, but will be used to generate fuel equal to 22 cylinders of 19 kg each per year,” said Nitin Deshpande, BMCC alumni and renowned industrialist, who has in collaboration with the organisations like Triocane, Gangotri, Vayu and GR Green Life, taken up the initiative.
The machine houses digester having 3,000 litres capacity and a Gas Storage Balloon of 3,000 litres. This machine does not need electricity and garbage can be put as it is without crushing it. It will produce a strong biological fertiliser, which will be used for the college garden.
BMCC is planning to install solar panel units on their buildings and minimise the use of electricity. The college incurs a bill of Rs 51 lakh per year for electricity, gas and water use and the plan is to bring the expenditure to zero, said Sharad Kunte, Chairman of Deccan Education Society (DES) Regulatory Board.
Water harvesting and plastic ban at IMDR and FC
The DES has planned to dig a trench alongside BMCC, Institute of Management Development and Research (IMDR) and Fergusson College wherein they will plant trees to support water harvesting on the campus. Deshpande said that since the college is situated at the foothill rainwater comes flowing down in large quantity. “The focus will be on storing that flowing water in the college premise through rainwater harvesting, eventually recharging the borewells and increasing the groundwater level,” said Deshpande. Similarly, Fergusson College (FC) has been making efforts toward complete stop of using plastic water bottles on the campus. “It has not 100 per cent stopped, but we trying to do so. For past four to five years we have started giving aways gifts in either cloth bags or paper bags and have avoided use of plastic. The hostels have solar panels,” said Ravindra Pardeshi, Principal of FC.
Green Buildings for CoEP
College of Engineering, Pune (CoEP) has been mulling on having green buildings on the campus. “We are in process to build a library of the green building. There are provisions to build such buildings like use of alternative energy, natural lighting entering the rooms and solar panel. This will keep the rooms cooler naturally. We have heritage buildings which do not have any air conditioning. However, we have them installed at computer rooms and other closed rooms where such installment is necessary,” said BB Ahuja, Director of CoEP.
CoEP has also alloted specific vehicle parking areas to avoid pollution. Students generally walk around on the campus. Specific parking lots are observed at most of the colleges in the city.
Sewage treatment plants at Symbiosis
Symbiosis International University (SIU) as 20 rainwater harvesting recharge pits and one rainwater harvest tank of capacity 240 cubic metres at the Lavale campus. It has sewage treatment plants at Kirkee, Lavale, Hinjewadi, Bengaluru and Hyderabad campuses for recycling of waste water for watering plants, lawns and gardens, flushing and washing floors. Drip irrigation system is used for garden.
It has developed a user-friendly method called ‘Nisarglaxmi’ for processing household organic waste into quality compost at household and society levels. The university campus has systems like biogas and composting units.
