Rapid development and urbanization Constant change in consumption pattern Social behaviour and uncivil attitude
Average daily per capita generation comes to 0.178 kg
0.034 kg for Koothuparamba to 0.707 kg for Thalassery (CESS, 2001; Padmalal & Maya, 2002; Varma &Dileepkumar, 2004).
MSW of 0.5 kg/capita/day in large cities (NEERI, 1996).
MSW generation varies between 0.21-0.35 kg/capita/day in the urban centres

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)
Traditional Composting (Existing methods not user friendly)

COMPOSTING
“Composting is the natural process of 'rotting' or decomposition of organic matter by microorganisms under controlled conditions. ”

Aerobic Vs. Anaerobic Composting
Aerobic CompostingOxygen present
Low methane emission
No bad smell
High heat generated
Rapid decomposition
Lower salinity
Anaerobic CompostingOxygen absent
High methane emission
Disagreeable odour
Less heat generated
Slow decomposition
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

Aerobic composting takes place in the presence of ample oxygen.
Temperature rises rapidly in the waste. In this process the temperature rises to 70 to
80° C. This peak temperature kills the pathogens and weed seeds.
Every waste in the farm can be utilized as a raw material for the compost making and
every material are put in the compost with the layers of dung.
By the time the composting is completed the material become dark brown in color.
70 to 75 degrees Celsius
