Investigation of Agricultural and Industrial Waste for Laterite Soil Stabilization

Abstract

Solid waste must be disposed which are the result of various human activities which include industrial, building, medical and agricultural waste.The building waste is the waste due to demolition, rehabilitation, repair and removal of existing structures and installations. The commonly found waste in garbage include sand,glass,stone, gravel, tiles, ceramic, marble, wood, paints, pipes, electric parts, asbestos, steel etc. The Nashik municipal corporation daily collects 300-350 tons of municipal solid waste (MSW). As per the report the 37.8% consist of easily compostable materials, 19.50% contains hard lignite’sand other material that biodegrade slowly. The 16.20 % consists of non-food items such as textiles, plastics, rubber which are non-biodegradable, which is a big concern for disposal. To solve this disposal problem new techniques should be considered to achieve a long term solution of landfill management. The use of waste material in road embankment can reduced the cost of construction of road by 10 to 20%. The flyash is the waste product of coal which is available inat electricity power plant. The transportation cost of waste material and laying cost of waste material need to be considered when considering it as a fill material. Laterite soil is week in stabilization due to its less molecular attraction between the soil particles
