In India, cassava cultivation is confined in South India. In Tamil Nadu, tubers
are used as raw material for starch and sago industry. About 8–10 largescale
starch factories and 150–200 small-scale starch and sago production
units are generating nearly 40–60 tonnes of solid waste (thippi) per annum
creating serious environmental pollution. A study undertaken to manage it
through composting to a nutrient-rich organic manure revealed thippi as
acidic with low major and micronutrient concentration, high water-holding
capacity, good porosity, low bulk density, high starch, fiber, low protein,
and cyanide. Composting of thippi with different combinations of raw
materials, microbial cultures, and earthworms indicated that thippi enriched
with gliricida and cassava leaves and composted with earthworm had the
highest nutrient concentration with narrow carbon to nitrogen (C:N) ratio.
The mean concentrations of N, phosphorus (P), potassium (K) calcium (Ca)
and magnesium (Mg), iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn)
in thippi compost were 1.32, 3.82, 0.40, 2.18, 0.96, 1.11, 0.08%, 11.23, and
89.93 mg/kg, respectively, which is 3.5, 49,7, 32.5, 8, 185, 100, 2.5, and 12
times than thippi. Thippi compost had low bulk density, starch, without
fiber and cyanide but high protein suggesting this protocol as a possible
alternative for the management of thippi.
