Circular Economy

SIERA intends to promote resource efficiency by closing material loops and reducing waste. It includes:

Landfill Technology for safe and controlled disposal
Waste to Resource Management to convert waste into valuable inputs
Remediation of Contaminated Sites to restore usability
Building Refurbishment to extend asset life sustainably
Dismantling for responsible material recovery reuse.

These approaches drive resource efficiency by closing material loops and extending the life cycle of assets sustainably.
