Composting – the process of producing
compost (organic fertilizer)
from biodegradable materials
through microorganisms
(anaerobic and aerobic)
2
PrinciplesPrinciples� A Carbon to Nitrogen Ratio of 25-35:1 for materials
needed for efficient bacterial decomposition
� Moisture content of at least 40% is required
� Rate of composting is 2-24 weeks depending on
conditions
� Quality of compost depends on the materials used and
the organisms involved

The Legal Basis of CompostingThe Legal Basis of Composting
� Prohibits open dump site of waste disposal

The Legal Basis of CompostingThe Legal Basis of Composting
� Requires the segregation of solid wastes

Vermicomposting – the process of producing
vermicomposting (organic
fertilizer or soil amendment) from
biodegradable materials through
the action of microorganisms and
earthworms
Principles: The same as composting
5
Advantage of Vermicompost vs. Ordinary compostAdvantage of Vermicompost vs. Ordinary compost
� Faster to produce (2-4 weeks with earthworms as
bioreactors)
� Less labor needed – worms do the turning over
� Granular texture (fine and grainy)
� Greater microbial diversity (beneficial organisms)
� High-quality organic fertilizer (no soil present)
� Contains humic acid and plant growth regulators
� Pleasant odor and does not “heat”
� Produces earthworm biomass

Rural VermicompostingRural Vermicomposting
�The application of vermicomposting for
recycling crop residues (e.g. rice straw and
cane tops) and animal wastes (e.g. pig,
cattle and poultry manures) into
vermicompost/vermimeal for sustainable
agriculture and aquaculture

Urban VermicompostingUrban Vermicomposting
� The application of vermicomposting for
recycling of biodegradable household
and other wastes into vermicompost for
environmental sanitation, food
production and livelihood generation
