Why composting is necessary?

• The rejected biological materials contain complex chemical compounds such as lignin, cellulose, hemicellulose, polysaccharides, proteins, lipids etc.
• These complex materials cannot be used as such as resource materials.
• The complex materials should be converted into simple inorganic element as available nutrient.
• The material put into soil without conversion will undergo conversion inside the soil.
• This conversion process take away all energy and available nutrients from the soil affecting the crop.
• Hence conversion period is mandatory.
