Livestock waste dumped in public places -- a civic problem Dead animals and Birds are thrown into water bodies, rivers and streams Carcass on Highway sides –Pollute—attract Dogs and carnivores accidents Animal parts carried by crows and carnivores spreads pathogens
On farm disposal
of Livestock waste in Kerala
Burial (labour intensive, carelessness attract carnivores) Incineration (need an incinerator ,costly, labour intensive) Pit disposal (carnivores dig it out, pollute water bodies ) Sanitary land fill(seepage, attract public protest ,carnivores) Composting (Existing methods not user friendly)
Aerobic Vs. Anaerobic Composting Aerobic Composting
Anaerobic Composting
Oxygen present
Oxygen absent
Low methane emission
High methane emission
No bad smell
Disagreeable odour
High heat generated
Less heat generated
Rapid decomposition
Slow decomposition
Lower salinity
Higher salinity.
Aerobic composting Vs Vermi composting
• Less labour needed • High layer temperature • Less time required
• Labour intensive • No temperature rise • More time for composting • Worms care and sustainability a must
Why Thumburmuzhy Composting? Environment friendly No disagreeable odours Organic waste converted to a value added product Improves soil stability and fertility Less area requirement Less expensive
Pathogens free
Select an ideal space. roof in monsoon
3 models were researched for economic feasibility at CBF
Floor can be Ferro cement slabs
Aerobic composting takes place in the presence of ample oxygen.
.
Temperature rises rapidly in the waste. This peak temperature kills the pathogens and weed seeds
.
Every waste in the farm can be utilized as a raw material
By the time the composting is completed the material become dark brown in colour.
Layers of Dung carbon source and organic waste
Cow dung + Carbon source + Organic waste + moisture C:N ratio = 20:1 Moisture content = 60% Temperature to be checked fortnightly
.90 days for composting in Thumburmuzhy model at Kerala agro climatic conditions
The Thumburmuzhy fodder grown organically
Thumburmuzhy Model aerobic compost
No fly menace or odour due to high temperature High temperature retained for about one week Decomposed wastes settle down No seepage Manure can be taken within 12-15 weeks Manure can be priced about Rs. 5 / kg
A new layering system for Kerala Agro zones
New cost effective construction technique
Suitable for composting the animal waste and carcass
Not labour intensive
Minimum care needed
Less methane and carbon dioxide so Ecofriendly
Harvested compost
