Sand mining has environmental impacts such as river bank collapse, loss of aquatic habitat, and increased erosion. M-sand is presented as an alternative to river sand for construction. M-sand is manufactured by crushing rocks and stones and offers benefits like reduced costs and a more eco-friendly alternative. To improve the sustainability and resilience of construction supply chains, strategies are recommended like implementing buffers, diversifying networks, investing in demand forecasting, and standardizing processes. Evaluating supply chain sustainability can help managers make better decisions to integrate environmental and supply chain management practices.

3.  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.  Collapse of river bank.
 Risk to aquatic habitat
 Force the river to change course
 Reduced light penetration
 Increase erosion
 Loss of agriculture land

5.  Environmental Uncertainty
 Information technology
 Supply chain relationship
 Business management
 Customer satisfaction

6.  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.  Reduce transportation cost
 Less processing cost
 Easily available
 Eco-friendly
 High strength of concrete
 Better workability of concrete

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

9.  Construction activities are not eco-friendly and it contributes significantly to environmental
deterioration in many countries. The environmental impact of emissions, energy usage and
poisonous by-products from the production process and the end product is very immense.
 Supply chain management is a great opportunity for the construction industry primarily to
reduce cost and time, and also it improves profitability. SCM principles seem to have much
strength to integrate and smoothen the construction processes.
 The way to improve the construction supply chain delivers projects is necessary to achieve
customer fulfillment, ecological efficiency, effectiveness, adequacy and benefit. Green Supply
Chain Management improves the economic and environmental performance of an industry.
 In order to ensure the effective joining of environmental and supply chain management, it is
important to perform the evaluation of GSCM.
 Evaluating supply chain sustainability can be useful and applicable for managers to make
more informative and reliable decisions in anticipated changes of construction markets, since
the competitive and global dimensions of GSCM are important.
