In the kitchen (and sometimes outside it) we produce a lot of organic waste. When we mix this waste with plastics, metal, chemical waste and send it to a landfill, it not only creates a lot of pollution but also makes it difficult to separate and recycle waste. All the smell from the dustbins/landfills are caused due to this organic waste from kitchen, mostly.
So can we do anything about it?
Yes. We can collect organic waste (food waste, vegetable peels, fruit leftovers, cooked meal leftovers, etc.) and inorganic waste (plastic, metal, etc.) in separate dustbins and deposit only the inorganic waste in the dustbins/dumps.
But what do we do with the Organic waste?
Turn it into money! You can generate both biogas for cooking and compost for plants in the garden if you deposit the organic waste into a biogas digester plant.
But aren't the biogas digester plants very big & require a lot of space?
Some are, not all. There are small biogas digester units for homes/families too. For example, a 1m3 (one meter cube) biogas digester plant requires a space of 4 x 5 feet only. It generates 1m3 of biogas when 6 - 10 Kgs of organic waste is digested by it, which gives a continuous flame for 2 hours. The biogas stove/burner is separate from (but similar to) the normal LPG stove/burner and requires simple piping system for carrying the gas. It may not replace LPG cylinders but can reduce the no. of LPG cylinders required for a family.
What about Compost?
After organic material is digested, compost will come out of the digester (as a byproduct) which is mixed with water and can be used as manure for home/kitchen garden. Note that this byproduct may induce some smell and hence need to be stored in closed containers. However, there will be no smell coming from the main unit unless there is a leak. There is no need to buy or make compost for your garden/kitchen garden if you have this system.
Can I Install it in my House?
Yes, if you have some space - preferably open space exposed to sunlight - you can install this unit in your house/terrace.
Of course, there are separate (larger) biogas plants for organizations like eateries, hotels, etc. that generate a lot of organic waste.
If you live in Chennai, have a look at B-Sustain who offer Biogas Digester plants in varying capacities. Or you can contact Vibrant Marketing if you have any sales enquiries.
