## 1. Importance of Metal Crushers in Kerala
1.1 Role in Construction & Infrastructure
Metal crushers produce raw materials necessary for:
– Road construction
– Building foundations
– Concrete manufacturing
– Railway ballast
Given Kerala’s rapid urbanization and infrastructure projects like highways and metro rail expansions, demand for crushed stone remains high.
1.2 Employment Generation
The industry provides direct employment to thousands of workers in quarrying, crushing units, transportation, and sales. Indirectly, it supports allied sectors such as logistics and machinery manufacturing.
1.3 Contribution to State Economy
Metal crushers contribute significantly to Kerala’s GDP by supplying raw materials at competitive prices compared to imports from neighboring states.

## 2. Regulatory Framework Governing Metal Crushers
2.1 Licensing & Permissions
Operating a metal crusher unit requires multiple approvals:
– Consent from the Kerala State Pollution Control Board (KSPCB)
– Mining license from the Department of Mining & Geology
– Clearance under the Air (Prevention & Control of Pollution) Act
– Compliance with Noise Pollution Regulations
2.2 Environmental Guidelines
Due to concerns over dust pollution and groundwater contamination:
– Crushers must install dust suppression systems (water sprinklers).
– Units should be located at least 500 meters from residential areas.
– Periodic environmental audits are mandatory..jpg)
2.3 Recent Policy Changes
The Kerala government has introduced stricter norms:
– Ban on illegal quarrying near ecologically sensitive zones (Western Ghats).
– Mandatory use of noise barriers in densely populated regions.

## 3. Environmental Concerns & Mitigation Measures
3.1 Dust Pollution
Crushing operations generate fine particulate matter (PM10 & PM2.5), affecting air quality.
# *Solutions:*
– Wet crushing methods
– Enclosed crushing chambers
– Green belts around units
