Effect of Bisphenol-A on the Bioconversion of Tea Waste into Vermicompost by Eudrilus Eugeniae (Kinberg, 1867) at Different Intervals

Abstract

Abstract: Vermicompost has been appropriate alternative for the best hygienic and cost effective disposal of wastes. Since the vermitechnology is considered as one of the best methods, the largely available tea waste was taken to the present work to study the efficiency the Eudrilus eugeniae in the management of such waste by converting it into vermicompost. The efficiency of the conversion of Tea waste into compost in the form minerals N, P, K and Fe, Mn, Zn, Cu by Eudrilus eugeniae has been analyzed on 15 th and 30 th days. Physical characteristic were also analyzed simultaneously to understand the efficiency of earthworm in maintaining the physical status of the soil. Macro and micro nutrients were increased significantly on 15 th and 30 th days. FTIR spectrum was recorded for the control and experimental compost. The variation of spectrum was noted. The Spectrum of experimental consisted of nitrogen rich peak. The control system has no N-H stretching peak whereas tea waste spectra has N-H stretching peak. The peak at Bisphenol-A leads to large number of hydrogen group i.e., the mixture has more moisture than the control system. The tea waste has flavonoids which also exhibit the OH group at the same system. To understand the anatomy, histology of the different parts of the earthworm was studied. Histology of the tested anterior region of Earthworm reveals that the cuticle is not much damaged. The dorsal and ventral blood vessel ruined largely. The control animal of clitellar region showed intact structure of internal organs. The coelom and Blood vessels are well marked. In the experimental animal, the clitellar region showed slight modification of the anatomy. The pigment cells are prominent in the waste treatment with Bisphenol-A. In some places, the circular muscles are disorganized. In middle region, the cuticle and the epidermis are intact. The study reveals the impact of the Bisphenol on the conversion of tea waste into compost.
