Title Slide

|| Welcome to the spoken tutorial on '''Wet waste management composting.'''

|-
|| 
|| In this tutorial, we will discuss another method of treating municipal solid waste called composting.

|| Follow this simple step-by-step guide for home composting.


'''Step 1'''

Select any large container (basket/ earthen pot/ bin) with a height of not more than 3 feet, with a suitable width.

Suitable to fit sufficient amount of wet waste generated by the family.


It is assumed that a family of 4 generates 600-700 gms of wet waste per day. 


Compost takes about 30 days to be created in home-composting conditions.

|| '''Step 2'''

Ensure that it has proper aeration. 


If not, drill suitable-sized holes on the sides, bottom, and the lid of the container.

|-

|| '''Step 3 '''

Add dry leaves/lump-free old compost/ loose soil/ loose coconut husk at the bottom of the container.

|| '''Step 4'''

* Add your kitchen waste to the compost bin.
* Ensure that you put the kitchen waste in lightly, without pressing down hard. 
* Strain as much water as possible from any leftover food item before adding it into the compost bin.
* Try to make small pieces (not paste) of the waste before adding it in.

|| '''Step 5'''

Sprinkle a few drops of buttermilk (if desired) and some garden soil on top to ensure the waste is fully covered.

|-

|| '''Step 6'''

Properly cover the bin with a lid from the top.

|| '''Step 7'''
* Repeat this process daily. 
* Every day prior to adding the waste, check the contents for moisture/smell. 
* Wipe any water droplets off the cover.
|-
|| Image

[[Image:]]
|| '''Step 8'''

* Start the same process with another container, once the first container is about 80% full. 
* For a family of 3-4 people, generally 2 containers are sufficient.
* Keep a record of start and end dates for every container.

|| '''Home Composting FAQs'''

FAQ 1: My compost bin is smelling unpleasant. What should I do?


The reasons could be 
# too much moisture/watery contents
# less/no aeration, lumpy contents or 
# improper addition of waste
|-
|| Image

[[Image:]] as per narration 

||Solution: Try one/more of these steps:


# Churn the contents
# Try to cut long stems into pieces of about 1-2 inches
# Loosen the waste while adding and don’t press down after adding
# If more waste is to be added on the same day, make alternate layers of waste and dry leaves/loose soil
# Add more soil/ dry leaves/ cocopeat/ shredded paper
# Keep the bin open for some time for moisture to escape
# If you are using a plastic bin/ bucket, try to add more holes/perforations
# Try to dry the wet waste before adding

|| FAQ 2: 

My composting process seems to be going slowly. What can I do?


Explanation: The reason could be that the contents are too wet. 

There needs to be additional dry components added to the compost to enable an efficient process.


Items such as egg shells/ dry leaves/ old soil/ hard stems of vegetables can be added as the dry component.
|-
||[[Image:]] as per narration 
||Solutions:
# Sprinkle (don’t pour) water on top
# Try to add more green waste
# Try to shred the hard contents to as small a size as possible prior to adding it to the compost bin
# Sometimes adding a different source of bacterium helps. 

For eg: buttermilk, EM solution, old compost

|| FAQ 3: What ‘culture’ is to be used for ‘fast’ composting?


Explanation: Culture is a mixture of microbes used to speed up or aid the composting process. 


A culture is not essential for composting to start.
|-
||[[Image:]] as per narration 
||Solution: the following things can be used as culture

A slurry of 

* Cow dung, 
* Buttermilk, 
* A handful of old compost
* Garden soil 
* Jeevamrut or EM solutions which are easily available in the market, can also be used.

|| FAQ 4: What should I do if there are maggots/slugs in the compost bin?


Explanation: Maggots/ slugs don’t harm the compost or you.
|-
||[[Image:]] as per narration 
||Solution: Can be avoided by putting netting on the bigger holes in the compost bin


Additionally, always cover the bin contents with dry leaves as the top layer.

|| FAQ 5: What organic waste should not be added to the compost bin?


Solution: Although anything that comes from the earth can go back to it, there are some exceptions. 


All organic matter take different times to decompose. 
|-
||[[Image:]] as per narration 
||Items like coconut shells, chicken/ fish bones, etc. take a very long time in the home compost bin.


They need to be shredded or broken into tiny pieces to decompose faster.

|| FAQ 6: How do I know the compost is ready? What to do with the compost after it is ready?


Ready compost is black, soil-like matter with an earthy smell.
|-
||[[Image:]] as per narration 
||Sieving might be required to remove any non-composted parts.


It can be used in the home garden/pots, along with soil and coconut husk to grow fresh plants.
|-
||[[Image:]] as per narration 
||Compost should be properly dried before storing it.
