STATUS OF SOLID WASTE MANAGEMENT IN BANGALORE & REVIEW OF SOLID WASTE TECHNIQ...Dr. Naveen BP
Municipal Solid Waste (MSW) management is one of the vital issues in the
contemporary urban environment, more particularly in developing countries. Municipal solid
waste generation consists of organic and inorganic waste materials generated by various
activities of the society. Improper disposal of solid wastes can pollute all vital components of the
environment (i.e., air, land and water). This paper addresses the status of waste management
practice in Bangalore city, the state capital of Karnataka (which is one of the fastest developing
cities in Asia) and a review of waste treatment technologies adopted to keep in the trends of
waste management practice over time. The Bangalore metropolitan (BBMP) area covers an area
of 1258 sq km and with a population of about 9.0 million generates around 4000 MT/day of
municipal solid waste (MSW) at an average of 0.27 kg/day/per capita. Presently, Bangalore city
faced with the problems with such high quantities of solid waste continuously and it is planning
to upgrade its management system. The major issues in Bangalore city is open dumping without
a liner and without a leachate management facility and the threat of ground water pollution, as
well as saturation of an existing landfill site are the most pressing problems for the city today.
This paper describes the current practices of waste technologies for composting. The importance
of participatory process of each sector of society to enable waste management socio
economically sustainable and ultimately provide an environmentally sustainable solid waste
management system. The major problems in MSW management at Bangalore are due to the lack
of waste segregation at source, low operational efficiency of waste transport system with old
vehicles, low collection efficiency in newly added residential and industrial areas, and an
inefficient and informal recycling system. As per the MSW Rules, the wet waste can be collected
door-to-door in an ideally bin-less city and sent for composting, while the dry waste can be left
to the informal sector like rag pickers and kabadiwalas for recycling. The MSW Rules make it
mandatory for biodegradable urban wastes for composting / vermicomposting, etc, and bans the
burning of garbage and the dry leaves. Bangalore city might need to focus for a better solution of
waste disposal considering unavailability of landfill sites. In this context a review of solid waste
techniques adopted within India and elsewhere will be reviewed and summarized with
recommendations.

CHARACTERISTICS OF THE LEACHATE FROM MSW LANDFILL,BANGALORE Dr. Naveen BP
Bangalore city generates about 4,500 metric tons of municipal solid waste every day in that 75% is disposed in the landfill. The landfill leachate discharge may lead to serious environmental problems. Leachate may percolate through landfill liners and subsoil causing pollution of ground water and surface waters resources. The aim of this research study is to identify the characteristics of the leachate from landfill in Mavallipura. Landfill leachate contains various pollutants that can be categorized into four groups such as dissolved organic matter, inorganic macrocomponents, heavy metals, and organic compounds. The pH of the leachate is considered as alkaline as the pH is 7.6 in Mavallipura landfill leachate. The results showed that the highest metal concentration that exists in the leachate was Iron which is about of 12 ppm. BOD
and COD of the leachate are 1500 mg/L and 10400 mg/L, respectively. The leachate characteristics indicate favourable growth of algae in natural water contaminated with leachate with the alkaline condition and with the presence of magnesium as nutrient, which has been confirmed in the nearby surface pond.
CHARACTERIZATION OF LEACHATE FROM MUNCIPAL LANDFILL AND ITS EFFECT ON SURROUN...Dr. Naveen BP
Percolating water passing through waste becomes contaminated and will have dissolved soluble organic and inorganic compounds as well as suspended particles. Also the pore fluid of the waste is often released and mixes with this water. The entire contaminated fluid is called leachate. There are many factors that affect leachate production like annual precipitation, runoff, infiltration, evaporation, transpiration, and freezing, mean ambient temperature, waste composition, waste density, initial moisture content, and depth of the waste fill. The production of leachate reduces when a landfill is closed. The decomposition of waste in presence of water can be separated into two different phases of degradation viz., initial aerobic and subsequent anaerobic. Generally, the leachate undergoes natural chemical changes over time that reduces its toxicity. Some of the soluble contaminants enrich the water table, or the saturated zone. Some of remaining molecules naturally adsorbed to the clay liner particles. The paper discusses the characteristics of leachate generated from municipal solid waste landfill and its effect on surrounding water bodies near Mavallipura landfill area in Bangalore. Two samples of water from the nearby pond and well were collected from downstream of Mavallipura landfill site. Physico-chemical characterization of leachate has shown that the leachate contains high concentrations of organic and inorganic constituents beyond the permissible limits. While the heavy metals concentration was in traces as the waste is dumped in the landfill is mainly domestic in nature. The pH of the leachate is marginally alkaline as the pH is 7.4. The results also showed that the highest metal concentration that exists in the leachate was Iron which is about of 11.16 ppm. BOD5 and COD of the leachate are 1500 mg/l and 10400 mg/l, respectively. The leachate characteristics indicate favorable growth of algae in natural water contaminated with leachate with the alkaline condition and with the presence of magnesium as nutrient, which has been confirmed in the nearby surface pond. Knowledge of leachate quality will be useful in planning and providing remedial measures to protect surface and ground water quality in the area.
