1. Biogas use in hospitals. A win-win for disposing medical waste with bio-digestion
Getting rid of infectious organic waste in hospitals through low-tech, sustainable biogesters not only captures methane gas and turns it into low-cost biogas, but it also reduces air pollution and its impact on climate change.
There has been so much focus over the years on how to treat infectious waste from hospitals and other healthcare facilities, but far less attention when it comes to organic waste produced there. This can pose a serious health hazard.
If not properly disposed of, infectious organic waste – which includes kitchen waste and pathological waste such as placentas – can attract flies, rats and feral animals. They are all capable of spreading disease. It smells terrible as it decomposes, and generates methane, a powerful greenhouse gas. In many countries, there are laws that force medical facilities to incinerate placentas and other wastes.
It doesn’t have to be this way. In fact, there is a safer and more sustainable, as well as low-cost and low-tech, way to dispose of this waste. It provides environmental benefits when it comes to energy use with less reliance on fossil fuels. That way is through bio-digestion.

2. Biogas plant at K.R. Hospital
1.2 kg cooking gas from 2 kg kitchen wastes a day
For the urbanites facing energy crisis, producing renewable energy is the only solution. This can be done by producing biogas using kitchen wastes. they solve two other major problems — overcoming the scarcity of LPG and disposal of solid wastes.
With merely two kgs of kitchen waste a day, your biogas unit, installed at a very affordable cost, can produce enough biogas for cooking at least for three hours a day. Thus, you have not only saved the trouble of disposing the wastes but also have reduced LPG consumption. Moreover, the kitchen waste slurry released after producing biogas can be used as manure for your kitchen garden. The quantum of production and its profits are directly proportional to the capacity of biogas plant. If installed in institutions where the quantity of organic wastes is more, the unit will prove to be more beneficial. Take for example the Biogas Unit newly- installed at K.R. Hospital at a cost of Rs. 1.20 lakh. It uses kitchen wastes of Nursing Students’ Hostel.
The unit, installed by National College of Engineering’s Centre for Renewable Energy and Sustainable Technologies (NIE-CREST), is the first of its kind in city at an institutional level. ”
K.R. Hospital project is an initiative undertaken by its Medical Superintendent Dr. Geetha Avadhani, assisted by Prof. Jagannath of ATI. It is supported by the Karnataka State Urban and Rural Development Pro-gramme with technical know-how provided by engineer Shamsundar. Cost of annual maintenance (to ensure that organic wastes are segregated from non-biodegradable wastes) is sponsored by R.N. Murthy of Rangarao & Sons.

3. Holy Family Hospital starts Rs 13-lakh biogas plant
To convert kitchen waste into gas for cooking purposes
Taking a step towards going green, the Holy Family Hospital in Bandra on Saturday inaugurated a plant to convert over 120 kg of kitchen waste — produced daily — into biogas and liquid organic fertilizers. The plant will require 20 minutes to feed kitchen waste and generate one cylinder of gas, which will be used for cooking. Also, the hospital plans to use the liquid organic fertilizer to maintain its plants.
The 286-bedded private hospital follows Bhabha Hospital, which was the first government hospital to produce biogas for energy conservation. In Dr R N Cooper Hospital, waste water is recycled for garden and bathrooms.
Felix Fernandes, the finance director at Holy Family, said the plant — which covers an area of over 1,000 sq ft — has been set up at a cost of Rs 13 lakh.
4. Hospital produces energy from waste in Nuwakot
Biogas use in hospital in Nuwakot
The Trishuli Hospital in Nuwakot has started producing energy from the waste generated by the hospital. The bio-degradable waste from the hospital has been used to produce energy (methane gas) through a biogas plant.
Chief of the Nuwakot hospital Dr Dipendra Pandey said a biogas plant with a capacity of 40 cubic meters has been put into operation with the help of the Bagmati provincial government. The plant cost Rs 800,000. Placenta from the delivery room, human body parts during surgery, food waste from patients and visitors, etc., have been disposed of in a plant built in the hospital premises.
The fuel produced by the plant has been enough to be used for cooking 15 people living in the doctor’s quarter.
Chairperson of the Hospital Development and Management Committee Raju Pandit said that the operation of the plant has solved the problem of disposing of hospital-related waste. It also controls the communicable diseases that may be caused by waste while fuel production has saved the hospital’s expenses. The goal is now to increase the range of energy production and sell it to the hospital’s canteen, he added.
