The disposal of waste presents an increasing challenge to the administrative bodies of megacities.

A Composting unit over a drain may seem a little bit of a surprise for many. But, welcome to Borda in the jurisdiction of Margao Municipal Council where a composting unit is presently under construction on a water nullah.
While work on the composting unit has raised many an eyebrows, the Margao Municipal council has denied that work on the unit is being carried out by the Civic body.

Composting of leaf litter using the epigeic, exotic earthworm Eisenia fetida and the microbial kinetize (Quikompost) was carried out in order to compare their efficacies in waste management. The quantity of leaf litter composted and the biomass (earthworm/microbial) recovered after composting were increased with increasing the quantity of earthworm/microbial kinetizer.

The nitrogen enriched phosphocompost was prepared utilizing the abundantly available green biomass of Lantana camara and supplemented with 12.5 and 25.0 per cent levels of rock phosphate, 1.0% fertilizer nitrogen (urea), 5.0 and 10.0 per cent pyrite or by inoculation with Azotobacter chroococcum and Aspergillus awamori.
