Abstract - Marble industry is one of the most
was 12 billion tons in the year 2002 which 11 billion tons were industrial wastes and 1.6 which 11 billion tons were industrial wastes and 1.6 billion tons were municipal solid wastes (MSW). About 19 billion tons of solid wastes are expected to be generated annually by the year 2025 [4]. Annually, Asia alone generates _4.4 billion tons of solid wastes and MSW comprise 790 million tones (MT) of which about 48(_6%) MT are generated in India [4, 5]. By the year 2047, MSW generation in India, is expected to reach 300 MT and land requirement for disposal of this waste would be 169.6km2 as against which only 20.2km2 were occupied in 1997 for management of 48MT [5]. Fig. 1 shows the details on current status of solid waste (non-hazardous and hazardous waste) generation from different sources in India [2, 6]. As can be seen from Fig. 1 that apart from municipal wastes, the organic wastes from agricultural alone contribute more than 350 MT per year However, it is reported that about 600 MT of wastes have been generated in India from agricultural sources alone [7].
environmentally unfriendly industries, cutting the stones produces heat, slurry, rock fragments and dust. Although marble waste, in generally, includes non- radioactive byproducts and thus it does not induce climate changes .It destroys plant life. The dust particles usually contains CaCo 3 resulting in visual pollution Therefore very harmful to the road users. In this way it is very necessary to understand the behavior of marble slurry and dust and to use in this way that it becomes a useful thing for environment and highway users.
Key Words:
Marble dust, non- radioactive, CaCo3 (calcium carbonate), visual pollution.
1.INTRODUCTION Due to continuous increasing demands of housing for increasing population, there is need for constructional material increases. Similarly for housing we need connectivity through public roads and transport. In our country India, in every city there is very fast development of roads and highways and new colonies in the outer areas of all the cities .There is also liking of the new materials. Now a day’s granite and marble is very popular for the flooring and in other building constructions. Materials obtained by conventional method is not sufficient to cope up with the demands of the society. In addition with the cuttings marble slurry and wastes is also developing and creating problems to the public and nuisance for the road user’s .Now although improved version of machineries is being used but lot of waste material is being collected either in the fields or on road sides. Creating lot of problems to the highway users or spoiling the agricultural lands. Every year a large quantities of recycling materials is disposed of in landfills or arbitrarily discharged to the environment.
1.1 Marble slurry environment
and
their
impacts
The major quantity of wastes generated from agricultural sources are sugarcane baggage, paddy and wheat straw and husk, wastes of vegetables, food products, tea, oil production jute fiber, groundnut shell, wooden mill waste, coconut husk, cotton stalk etc., [2,6,8]. The major industrial non-hazardous inorganic solid wastes are coal combustion residues, bauxite red mud, tailings from aluminum, iron, copper and zinc primary extraction processes. Generation of all these inorganic industrial wastes in India is estimated to be _290 MT per annum [6, 9]. In India, _4.5 MT of hazardous wastes are being generated annually during different industrial process like electroplating, various metal extraction processes, galvanizing, refinery, petrochemical industries, pharmaceutical and pesticide industries [7,10]. However, it is envisaged that the total solid wastes from municipal, agricultural, nonhazardous and hazardous wastes generated from different industrial processes in India seem to be even higher than the reported data. Already accumulated solid wastes and their increasing annual production are a major source of pollution. Due to environmental degradation, energy

Solid wastes has been increased due to rise in living standards, technical innovations, industrial and mining wastes. Globally the estimated quantity of wastes generation
