This document discusses sand mining and the use of manufactured sand (M-sand) as an alternative. It outlines the drawbacks of sand mining, such as riverbank collapse and increased erosion. M-sand is introduced as a substitute made from crushed stone that has advantages like reduced costs and greater durability. The conclusion recommends regulating sand mining and rehabilitating mined areas, while using M-sand can help address the scarcity of river sand and prevent environmental problems from excessive mining.

3. INTRODUCTION
Sand Mining is a coastal activity referring to the
process of the actual removal of sand from the
foreshore including rivers, streams and lakes.
Sand is mined from beaches and inland dunes and
dredged from ocean beds and river beds.

4. DRAWBACKS OF SAND MINING
Collapse of river bank.
Loss of adjacent land or structure
Alteration River bed
Risk to aquatic habitat
Force the river to change course
Lead to flooding
Reduced light penetration
Increase erosion
Increase Turbidity
Loss of agriculture land

5. Factor affecting effective supply
chain management
Environmental Uncertainty
Information technology
Supply chain relationship
Manufacturing
Supply chain management performance
Business management
Customer satisfaction

6. Introduction of M-sand
M sand is a form of artificial sand, manufactured
by crushing large hard stones, mainly rocks or
granite, into fine particles, which is then washed
and finely graded. It is widely used as a substitute
for river sand for construction purposes, mostly in
the production of concrete and mortar mix.

7. Advantages of using M-sand &
Marketing Strategy
Reduce transportation cost
Less processing cost
Easily available
Decrease transportation time
Greater Durability
Eco-friendly
High strength of concrete
Better workability of concrete

8. Supply Chain Management Strategy
1. Place buffers along the supply chain
2. Diversify your manufacturing and sourcing network
3. Invest in demand forecasting
4. Standardize your processes

9. Conclusion
 The large-scale mining of rivers and below the existing streambed level has adverse
impacts on the existing environment.
 It is therefore concluded that the mining of sand should be subjected to a strict
regulatory regime and should be carried out based on the approved framework of
the mining plan. Also, it should provide rehabilitation and reclamation of the mined-
out zones in the future.
 So far, the inherent deficiencies of natural river sand are extensively used for the
modification of concrete properties by incorporating manufactured sand as a partial
replacement for river sand.
 It can also be concluded that the M-sand can be utilized as an efficient fine aggregate
in concrete in order to meet the global scarcity of river sand in the future.
 The use of M-sand eliminates the global scarcity of river sand, and it prevents
associated environmental problems such as indiscriminate sand mining and soil
erosion, thereby enhancing and contributing to environmental sustainability.
