Long term performance of 'vermireactors' in which paper waste was converted to vermicasts by the anecic earthworm Lampito mauritii Kinberg has been assessed. The study focussed on four aspects: (a) recovery of vermicasts in digesters fed with paper blended with cowdung in 4:1, 5:1, and 6:1 ratios (by weight), (b) reproduction/mortality of earthworms in the reactors, (c) growth of earthworms in terms of increase in zoomass, and (d) the effect of digester volume on the three aforementioned factors. These studies are a sequel to the work reported earlier(2) where four of epigeic and anecic earthworms were screened for their efficiency and sustainability in processing waste paper. The studies had indicated L. mauritii and Eudrilus eugeniae Kinberg to be the most efficient producers of vermicasts, with L. mauritii a shade above E. eugeniae. As L. mauritii is an indigenous species whereas E. eugeniae is an exotic in the Indian context, it seems that the former may adapt better ecologically, hence is more resilient than the latter.
