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
