We at Naandi pride ourselves on the fact that we have designed our community to be “grid free”. What does that mean?, well, we produce our own resources for sustenance – food, water and energy and we dispose our wastes at site only. Basically we have created an eco system that absorbs the wastes in itself after safe, eco friendly waste management.
We designed this seemingly large task by breaking it down into parts and handling them and then tacking each part on its own. Every part is then tied up to the larger eco system of food and energy to complete the cycle.
Handling Farm wastes
Farm wastes are equivalent to Gold for the farming community as they contain a lot of organic content that augment growth in plants. Just like how nature designed this cycle of ‘farm wastes to animals and animal wastes to farm’, we at Organo try to mimic this cycle to use our resources efficiently. Especially when we do not use any chemicals – pesticides or fertilizers, or any kind of medicines/hormones – that meddle with the natural processes – the waste from our animal husbandry unit acts as good manure to the farm.
To consider the amount of compost and power that is produced per day at Naandi we would have to look at the figures below –
Handling community wastes
Handling Household waste
An average household in India produces 500 Grams per person. This amounts to 175 kilos across 70 families at the rate of 5 people per family. This is composed of –
The Orgnic content of this waste goes into the bio gas digestor while the Plastics, Paper, Metal, Wastes and Textiles go into recycling. Especially today when the cyclic system is a well established process for many manufacturers such as this –
Today handling municipal wastes has become an issue at the national level wholly because “segregation at the source” does not happen. This mammoth sized problem of ‘waste’ can be handled well once we can efficiently segregate the waste at the source. To cultivate this behavior in the residents we have introduced an incentive based policy at the Naandi commune – the credit system. The credit system earns indirect rewards to the community members if the waste is disposed to the community after segregating.
Handling sewage wastes
The sewage at the Naandi community is handled by centralized SBR based technology – Sequential batch Reactor technology. This technology expedites the process of treatment as each of the bio film carriers which cause the treatment are in continuous motion. Also, in terms of Operation and Maintenance the SBR technology is self-maintained and can be increased in capacity very easily within the same tanks. This assures us of the efficiency of the treatment plant during seasons of high occupancy or low occupancy. The water treated in the plant is nutrient rich and can be used for agricultural irrigation. The solid waste that forms the sludge is again is connected to the food cycle of the farm as farm manure.
The base requirement of the cycle keeps the pressure on all the parts of the cycle and acts as a check point for all. This way Naandi is maintained without disposing any “wastes” into the environments, waste is almost considered as a precious in the community as one process provides the raw material for another.
