Environmental Audit is intended to quantify environmental performance and environmental position of an industry. Environmental audit report ideally contains a statement of environmental performance and position but may also aim to define what needs to be done to improve upon indicators of such performance and position. Present study is related to environmental audit of a distillery unit located near Kolhapur in Maharashtra. The environmental audit identified the various waste streams, waste minimization and treatment options in the distillery industry. The paper aims to substantiate the intension that the use of environmental audit practices help the industry to increase its productivity, and at the same time maintaining the environment.Keywords

Activated carbon was prepared from coconut leaves by using chemical activation method, using phosphoric acid as dehydrating agent and at slow pyrolysis of 400°C in inert atmosphere. The present study, explored the feasibility of using waste coconut leaves (CL) based carbon as adsorbent for the removal of lead under different temperature conditions from waste solution. BET surface area of CL3 found 1060.57 m2/g greater than CL1 and CL2. The batch sorption study experiments were conducted with respect to solute concentration (2.8-110 mg/L) and solution temperature (40-70°C). The Langmuir Isotherm, Freundlich Isotherm and Temkin Isotherm studies were conducted and applied to the experimental equilibrium data, and isotherm constants are calculated. A comparison of kinetic models was applied to the adsorption of lead ion. Coconut leaves carbon was evaluated for the, Elovich, intraparticle diffusion and Bangham's kinetic models. The experimental data fitted very well for the pseudo first-order and pseudo second-order. The results show that the sorption capacity increases with an increase in solution temperature from 40°C, 50°C, 60°C and 70°C. The results have established good potentiality for the carbon particles to be used as a sorbent for the removal of lead from wastewater.Keywords
