Rajasthan produces around 50% of the world's marble and generates millions of tons of waste from marble mining and processing each year. This waste comes from quarrying overburden and undersized material, and from cutting, polishing, and grinding during processing. Exposure of this waste can cause environmental problems like air and water pollution, damage to vegetation, and visual impacts. Proper management of marble waste is necessary to mitigate these problems and conserve resources. Some ways marble waste is being managed include using it to replace other materials in concrete and bricks, which increases strength while reducing costs.

1. Introduction
Rajasthan has around 4000 marble mines and about 1100 marble gang
saws (processing plants). The industry involves Mines, Processing plants,
Cutters for the production of tiles for walls and floors, articles, waste
reproduction and other ancillary works
Marble ranks the largest produced natural stone in the world and it
accounts for 50% of the world's natural stone production. Around 90% of
the world's production of marble comes from India and approx 85% of
India's production is received from Rajasthan and almost all mining and
processing activities are concentrated around Udaipur. In India, million
tons of waste from marble industry is being released every year from
marble cutting, polishing, processing and grinding. Although a portion of
this waste may be utilized on-site such as for excavation pit refill.
Exposing the waste material to the environment directly can cause
environmental problems
MARBLE WASTE
Mainly there are two broad categories of the marble waste viz.
(1) Waste generated during Quarrying
(2) Waste generated during Processing
(1) Waste generated during Quarrying:
(a) Overburden
(b) Side burden
(c) Inter burden
(d) Ungraded material
(e) Undersize material

2. (2) Waste generated during Processing
(a) Dressing Waste
(b) Cutting waste
(c) Polishing waste
ENVIRONMENTAL PROBLEMS DUE TO
WASTE
(a) Conservational
The valuable national wealth is getting wasted mainly due to lack of
management and lack of technology. This waste, if recovered as useful,
can change perhaps the entire scenario of the industry. Since it is not
impacting directly on the environment the non-conversion of useful
mining product is a more grave problem in longer term than other direct
problems.
(b) Air pollution
This is the most direct and hazardous impact of the industry. Slurry
produced at almost every operation and its dumping is a great problem.
When it gets dried and airborne, it causes air pollution and related
problems.
(c) Water pollution
Like any industry, the marble industry needs water in its different
operations for cooling and flushing different discharge. In these
operations water gets contaminated. This contamination is considerable

3. and it can be said that water pollution of the region is caused by
discharging slurry.
(d) Vegetation related problems
Due to opencast nature of the mining, De-vegetation of the area is
imminent. Dried slurry deposited over plants and vegetation hampers
their growth
(e) Visual impacts
Running mines, abandoned mines, dumping sites, slurry waste sites,
deposition of dried slurry over almost every structure in surrounding
areas are a very bad sight. Hills having been excavated and dumps over
them are very unaesthetic.
(f) Scarcity of the dump sites
The production of a large amount of waste needs additional land for its
dumping and handling.
(g) Accidents due to unscientific dumping
There are a number of accidents due to unscientific dumping of mine
waste on road and quarry sites.
NECESSITY OF WASTE MANAGEMENT
Generally these wastes pollute and damage the environment due to
sawing and polishing processes.
.
DISADVANTAGE OF MARBLE WASTE
(1) Marble slurry increases the soil alkalinity.
(2) Marble slurry affects the plants.

4. (3) Marble powder affects the human body.
(4) Marble slurry or powder affect the soil fertility and reduce them.
(5) The waste is dumped on land the dust is airborne by the wind and
makes air pollution in
environment.
(6) Marble slurry increases the accident of the slip
CONCLUSIONS
Marble waste used in brick production so increasethe strength. In the
different percentage of
the addition 10, 20, 30, 40 % in which 10% marble slurry use give the
maximum strength as
compared to other.
• Use of Marble Waste in Brick results in saving of soil.
• Marble Waste Savings on difference in cost of natural soil,
besides protection of environment.
• By using Marble Waste in bricks leads to solve the dumpling
problem.
HOW WASTE SHOULD BE MANAGED/IS BEING MANAGED
(1) Marble slurry is used for replacement of other material and saves the
material.
(2) Marble slurry used in concrete so Increase the strength in concrete.
(3) Marble slurry we get in nominal or free of cost.
(4) Marble scrape is used to make attractive flooring in minimum cost.
(5) Use of the marble waste decrease the cost of construction because
replace the material by marble waste
(6) In Fly ash brick if lime is replace by marble waste so increase the
strength of brick.
(7) Binding property of marble slurry is very good
