Sustainable Remediation in Action

Every day, we address environmental conditions to strengthen sites and reduce negative impacts. Each project is more than a job — it’s our opportunity to support sustainable remediation through green technologies and applications.

Focused goals, real results

Setting goals is the first step toward sustainability, but real results come with action. From strategy to execution, we measure our progress to drive continual improvement.

Goal: More efficient technology.

Action: Implement sustainable and green remediation technology at our project sites nationally.

Progress: We continue to adopt smart and sustainable technologies nationwide.

  • Remote monitoring systems
  • Mobile offices and virtual meeting platforms
  • New equipment, including tier 4 and exhaust scrubbers
  • In-situ or onsite containment solutions to reduce materials transport
  • Solar units and solar or battery-powered systems
  • Transport monitoring applications
  • Use of recycled products or reuse of onsite materials.
  • Electric-powered heavy equipment

Goal: Smarter systems for Carbon Reduction.

Action: Upgrade and innovate our working systems and processes to reduce carbon output.

Progress: We continue to update how we work to support sustainable remediation.

  • More efficient transport routes to minimize idling
  • Journey Management Plans to identify shortest haul routes
  • Increased use of ultra low sulfur diesel or biodiesel fuel
  • Utilization of rail or barge transport versus truck transport
  • More efficient and timelier remediation.
  • Encouragement of ridesharing, carpooling and public transit use among employees
  • Use of alternatives to carbon-intensive materials
  • Utilization of weigh-scale equipped excavators to ensure maximum capacity on load export trucks
  • Sourcing of local resources/subcontractors
  • Efficiency planning of machinery across projects
  • Purchase of renewable energy credits
  • Energy audits

Reducing carbon emissions for clients

In partnership with our clients — and in support of carbon reduction strategies — we design and implement projects that reduce both emissions and our environmental footprint.
ENTACT works with sustainability organizations to stay current on sustainable practices and identify state of the art technologies/practices capable of reducing carbon emissions.
