Effective Methods to Process Organic Waste in india -Organic wastes are those wastes which can be decomposed and if cultivated properly can be very useful resource.
Organic waste includes
- Kitchen waste: Egg peels, Fruits and vegetables, Leftover food etc.
- Garden waste: Dead plants and fallen flowers
- Agricultural waste: Wastes produced during various farm activities such as seed growing, dairy farming, livestock breeding, land grazing,
- Forest waste remains of animal bodies in forests
Sadly, these organic wastes are often misused by dumping them in landfills and further they undergo a lot of chemical and biological decomposition and then over time, finally produce methane gas which is harmful greenhouse gases.
But there is also and another side to use this waste.
The process in which biodegradable food waste is converted into manure full of nutrients and biogas is also generated
The process of anaerobic digestion includes:
Food waste is collected in big tanks without oxygen and then micro organisms gets to work breaking these wastes and creating fertilizers which can be used in farming and biogas which can be used to create heat and electricity
The whole process is called food recycling.
Out of the above organic waste, we will talk about kitchen waste.
Not all kitchen waste is bio degradable. So kitchen wastes are further divided into wet waste and dry waste. The main reason for segregation of dry waste and wet waste is recycling. The mix waste hampers the process of recycling and when dry waste comes in contact with wet waste it becomes difficult to recycle it.
Dry waste includes plastic bags, wrappers, kitchen tools of no use etc.
So the main two effective methods to process organic waste are:
1) Anaerobic digestion where waste is collected manually
2) Garbage disposers: where waste is segregated from household itself and no need for collection and with collaborative efforts of government and households there will be no landfill in near future.
The government also, has come up with the solution and Effective Methods to Process Organic Waste Eg- to make two different bin for segregation of dry waste and wet waste. Green Bin indicates wet waste and Blue bin indicates dry waste. Though the process looks easy but sometimes segregation is difficult and it’s a tedious job. And people don’t understand the concepts and don’t separate the waste. The problem remains the same in spite of government policies and fines.
There is also another way to deal with the small amount of our own household kitchen wet waste and that is installing garbage disposal unit.
Food wastes can also be managed by using a machine called Food Waste Crusher or a garbage disposal unit which is an electrically operated instrument used for crushing food wastes and also shreds wet waste in less than 2-3mm size and which directly goes in drains, thereby avoiding drain chokes caused by these food waste particles. These units can be fitted in various places like hotels, hostels, kitchen, restaurants, etc.
In countries like Britain some local authorities have subsidized the price of garbage waste disposal to decrease the amount of landfill.
Countries like Sweden encourages the installation of garbage waste disposer to increase the amount of biogas production.
Still in developing countries like India, it’s not as popular as in the developed countries. But many new Indian companies are coming up with this product.
The main benefits of this machine is now no more need of two bins for wet waste and dry waste and no more left over’s. And yes, it also helps to keep kitchen pest free and hygienic and it helps in maintaining the landfills and additional benefit in process of segregation; if planted at biogas station which in turn increases the production of biogas. It can be counted as an additional help in whole process of anaerobic digestion which is the need of the time.
The benefits of which are not limited to but are enlisted as below:
- It chews away the food leftovers and ensures hygiene in the kitchen
- It eliminated the foul smell caused by the leftovers
- It helps prevent the pipes from chocking.
- It paces up the cleaning process.
