The use of bio-cultures in waste management (India)

Bioremediation is an environment-friendly technique used for separating organic soil and recyclables from the municipal solid waste. Bioremediation is an alternate method to manage or to degrade municipal solid wastes which renders the environment free from pollutants with help of environmentally friendly micro-organisms. Bioremediation involves stimulating the growth of micro- organisms and degrading the pollutants without the use of any toxic chemicals to alter the environmental conditions in dumpsites. The present project work is an in-situ bioremediation being carried out at “AL Waste Bioremediation LLP” (project of Greater Noida industrial development authority) in Greater Noida. The facility at AL Waste Bioremediation LLP is a municipal solid waste dumpsite which is the source of municipal solid waste used for the study. These municipal solid wastes are bioremediated with commercially available bio-cultures over a predefined duration under atmospheric conditions of pressure and temperature. The aim of this thesis is to investigate the effect of different bio-cultures on fresh waste and legacy waste in implementation of bio-remediation of process under optimal conditions for different bio-cultures. The work also evaluates the effects of bio-cultures on bioremediation of fresh waste and legacy waste and its impact on the final bioremediated waste materials. The work further segregates refuse derived fuel and bio compost from bioremediated fresh waste and legacy waste. The work further involves characterization of refuse derived fuel and bio compost for various parameters.
