How to use the food waste !!!

[Ideas for Innovation]

In our company daily we generate more than 500 kg food waste, so how to use the food waste in proper way??

Vermi composting or bio gas or .....???

If anyone interested to use the food waste  means contact me ([e-mail]).

If you know any vermicomposting vendor or bio gas vendor available means, kindly tell the address ..

thanks,

Yasotharan.

You can also go for Organic Waste Converter. We are using it in our Company. It is very easy to install and cost wise it is very inexpensive and easy to maintenance. It consist of one digester and water curing system. As a raw material it uses kitchen waste and little amount of saw dust to absorb the moisture present in the Food waste. Overall Time to get the organic manure is of 10 days. On tenth day you can apply the manure in plantation activities.

It is manufactured by Excel Industries Limited.

It's cost vary from Rs. 3,50,000 to 5,00,000, depending on capacity of OWC. you will also need shredder with it for shredding of food wastes. It's cost is additional. YOu may find out the name of the company, to get quotation.

I agree with Subhajit, it is a good systm and insted of saw dust we are using lawn moved grass which is giving good results for last five years.

Hi Yasotharan,

This is Saurav from GreenBandhu and Earthima Technologies. We are a pioneer in solid-waste management. We can help you with your requirement, it all depends on the type of food-waste you are talking about. Composting is a very simple and cost-effective solution.

We manufacture systems - Chipy Chopy Organic Waste Crushers/Shredders that will crush, and shred your waste and finally treat it naturally in - RoliMoli Composters - with controlled aeration, temperature, moisture and pH.

You would require to use a carbon-rich material to neutralize the nitrogen-rich waste. To do so you can use either saw-dust or dry, shredded leaves.

Now, my question to you is, what type of food-waste do you want to treat? Is it cooked food, left-over food - after cooking? or vegetable peels, fruit peels - before cooking?

Lot of people do not understand the difference, that is reason they do not succeed in making the compost easily or sustainably.

For cooked, left-over food waste, very large in quantity, composting is not a good way because it costs a lot to maintain the pH value of the waste by using compost enhancer, saw-dust etc. There is an operational cost greater than the value of compost you make thus defeating the purpose. People will never tell you all these because they want to sell their machines.

We have a solution that will help you manage the cooked food, left-over waste economically. Do you have a STP?

The peels / pre-cooking waste can be easily composted.

Another thing that you should be aware of is the infrastructure requirement for setting up these machines such as does it require a room-setup, what space, electrical connection, water requirement, worker need etc.

We specialize in space-efficient, low energy requirement, no skilled labour type of systems.

I am attaching a pdf file for your perusal. Also, below is a list of some YouTube Videos of our work..

The method chosen to handle food waste depends on 2 important factors.

1) water content,

2) C/N ratio.

Generally, the material with lesser moisture, such as vegetable cuttings, spices and so on, can be simply fed for aerobic or vermicomposting. This can also be used for mulching in low quantities, over plant beds.

The material with more water/oil content is well handled by a anaerobic digester to draw methane. The output slurry of this one can be stabilised over an oxidation tank to kill all odour.

One cannot select a method in general, as there is no single best method. 

The best method is hybrid and that which caters to the variable nature of the material.

Biogas, vermicomposting, aerobic composting, STP, anaerobic digestion are just means that need to be studied and applied uniquely for each situation.

Fancy machines such as shredders and OWC are simply tools that have a commercial value as they draw attention and divert some budget. Compost has been made for millions of years without shredders and OWC.

Hi Yasotharan.

I think the biogas is the best solution for canteen waste management. For 500 kg food waste give u gas   daily around  equivalent to 20 kg LPG. After that also the slurry of biogas use a fertilizer.

It should be biogas+vermi. Produce gas and use slurry for Vermi and get both.

[Saurav Bardhan]

Point #3) pH. Aerobic Bacterias do not like acidic substrate / waste also acidic waste give rise to maggot problems and other vermins that most people do not like to see.

Machines are required for efficient management of huge quantities of waste. However, that does not mean unreasonable cost.

Finally, the way cities are growing today, there is very little space for managing waste. Thus, our systems are built in such a manner that they can be put up on the terrace as well or any little space available.

We have setup many systems all over India in cities like Delhi, Gurgaon, Chennai, Bangalore, Hyderabad, Pune, etc. in societies, corporates, schools, colleges, factories, and even in rural setup.

It is important to innovate as per need.

Thanks, Saurav

Biogas plants and vermi-composting plants have not been very successful due to inherent problems such as leakage, corrosion, maintenance, red worms are very expensive to buy and maintain and weather conditions are not very conducive at times. Finally, space requirement and cost of these setups are in my mind unreasonably high. Thanks, Saurav

Thank You Sir,

Your information is very valuable for us. We are also using incinerated paper ash instead of saw dust during emergency, when we do not have any saw dust. This also gives excellent NPK values to the compost.

Subhajit

can u tell me please the cost of the organic converter capacity space requirement etc i will be grateful

[Mrs. Lata Jha]

Biogas -to - electricity plants are running successfully, only thing it requires a good quantity of bio waste. 4 to 5 ton is good to run about 400 street lights.

Whereas for small quantity of SW the OWC - daily composting machines (drum composter) are available in capacity of 50 kg. onwards. Recently we have implemented 13 numbers in Navi Mumbai in housing societies to treat the waste at source. Total 2650 kg. SW will be converted into rich compost. These machines are totally automatic, require minimum electricity, single man power - only to dump waste into machine. Keep a bin to collect compost at outlet.
