Part 1:
WHAT and WHY of
COMPOSTING

z
WHAT is Composting? – Wet waste and
segregation
Wet waste is practically our kitchen and
garden waste
Waste segregation is the first step to
composting

z
WHAT is Composting?
Mostly aerobic: Greens (small size) +
Browns (shredded) + Microbes + Moisture +
Aeration; Heat generated that also kills
weeds and pathogens
Composting is recycling of organic matter ;
it is natural process but speeds up in an
ideal environment

z
WHY Do We Do Composting? Three
reasons
Wet waste
management
Soil natural
fertilization and
conditioning
Mitigating
climate
change

z
Diseases
due to
sanitation
issues
Choked
drains
Threat to
animals
Tourism
losses
WHY Do We Do Composting? Resolving
waste-related issues
COMPOSTING VESTS POWER IN OUR HANDS
TO MANAGE 50% OF OUR WASTE 

z
WHY Do We Do Composting? Soil
conditioning and enrichment
Improves root penetration by loosening the
soil
Improves water holding capacity
Protects surface soil from erosion
Makes soil stable
Increases aeration

z
WHY Do We Do Composting? Soil
conditioning and enrichment
Increases soil temperature by its dark color
Mulching effect helps moderate soil
temperature
Adds nutrients like N, P, K, Cu, Zn, etc. and
increasing nutrient-holding capacity of soil
Provides active agents for germinating
plants
Provides food for growth of beneficial
microbes and earthworms

z
Wet waste dumps release Methane (a
potent greenhouse gas which causes
climate change), accounting for 1.5% of
human-origin carbon emissions
Aerobic composting takes care of that
Wet waste is mostly food waste; so food
waste reduction critical and we will have
lesser waste to compost
WHY Do We Do Composting? Climate
Change Mitigation

Part 2: HOW to do
COMPOSTING correctly

z
HOW To Do Composting Correctly – Types
of Composting
Aerobic – Managed (also called HOT
composting)
Anerobic – Managed (in home settings with
anerobic bins) or unmanaged as in pits
(also called COLD composting)

z
HOW To Do Composting Correctly – Types
of Composting - Bokashi
Anerobic fermentation – yields a pre-
compost; pickled waste which is mixed
with cocopeat (provided with bins); time
taken 1.5 months; no odor; very easy
Bokashi Bins and bran (with specially
selected microbes); does NOT release
methane due to lowered pH
For ALL types of kitchen waste

z
HOW To Do Composting Correctly –
Aerobic - Basics
Greens: Nitrogen-rich food waste
Browns: Carbon-rich dry materials
Air by turning waste
Greens + Browns + Air + Moisture +
Microbes (Soil or compost or buttermilk or
commercial product)

z
HOW To Do Composting Correctly –
Aerobic in basic settings
GREENS
• General food
waste
• Coffee grounds
and tea leaves
• Grass clippings
• Fruit scraps and
peels
• Veg scraps
• Egg shells
BROWNS
• Dry leaves
• Twigs & branches
• Dead and dried
plants
• Saw dust and
wood chips
• Paper/cardboard

z
How To Do Composting Correctly – Which
method to use
Way of composting depends on what we
want to compost, at what level (individual
or community) , and with what level of
investment
Focus will be on home composting
(apartment and independent homes)

z
Basic Home Composting – Issues and
Solutions
Fruit flies – layer waste with Newspaper or
muslin cloth
Odor (mostly methane and hydrogen
sulfide or else ammonia) – If methane, then
turn; if ammonia, spread out and add
browns

z
Solutions
Bugs, small white worms (larvae of
shoulder fly) and white fungus – Normal; ;
make a moat for maggots
Appropriate temperature mgmt. by aeration
and moisturization

z
Solutions
Courtesy :Daily Dump Learning

z
Identifying Completely Done Compost,
Harvesting and Storage
Well-done compost is soil like, dark, crumbly
with earthly smell with no large chunks
It is neutral pH
For Daily Dump products, keep compost for
maturing for 1 month or more
Store in an airy, moisturized set up in any bin
or jute sack (for any period of time)

z
Using Compost Correctly
Either crumble in surface (top coat the soil)
Or
Till it in soil
Pots: 2-3 parts of top soil to 1 part of
compost

z
Using Compost Correctly
New Garden: 2” compost layer for 12” soil
Existing Garden: 2” addition yearly to
annual flower and vegetable gardens
Using ONLY compost as medium : less structural
support and excess of certain nutrients and
intervention in nutritional uptake and microbial
action
