Solid Waste

Expertise

You’re responsible for systems that most people never think about but communities rely on every day. Whether you’re navigating stricter regulations, planning new capacity, improving diversion, or upgrading aging infrastructure, solid waste decisions carry enormous operational, environmental, and financial impacts. You need a partner who understands how all the pieces fit together and can help you plan for today’s needs and tomorrow’s demands.

RESPEC supports clients across the full life cycle of solid waste management with engineering, operational insight, and environmental expertise. From permitting and facility design to monitoring, resource recovery, and renewable energy solutions, we help you build systems that run sustainably, meet regulatory requirements, and deliver long-term value to the communities you serve.

Turning Challenges Into Sustainable Solutions

Design & Permitting

Every successful facility starts with the right foundation. RESPEC guides clients through feasibility studies, site assessments, permitting, and design for landfills, transfer stations, recovery facilities, organics management, beneficial reuse and waste-to-energy projects. Our designs align with client budgets, regulations, and market needs while reducing risk and optimizing performance.

Leachate Treatment Solutions

Leachate is one of the industry’s toughest challenges. RESPEC engineers custom treatment systems using biological, chemical, and physical processes tailored to each site’s conditions. From pilot testing to full-scale implementation, we design solutions that reduce costs, meet compliance requirements, and protect surrounding water resources.

Conversion & Diversion

With zero-waste mandates and corporate environmental, social, and governance commitments on the rise, we help clients recover value from waste. Our expertise in material recovery, organics processing, composting, and alternative fuel production supports profitable diversion strategies that align with sustainability goals.

Monitoring & Reporting

Solid waste facilities face some of the most rigorous regulatory oversight. We deliver groundwater, surface water, and landfill gas monitoring programs backed by advanced data analysis and reporting tools. Our approach helps our clients remain compliant while giving them confidence in performance and transparency.

Facility Construction & Operations Support

We provide full life-cycle support—from predesign and contractor management to construction quality assurance and postclosure planning. Whether managing leachate systems, optimizing airspace, or supporting compliance reporting, RESPEC partners with clients to help facilities operate efficiently and profitably.

Biogas & Renewable Natural Gas (RNG)

Landfills are a major source of methane emissions—and also a renewable energy opportunity. We design systems that maximize gas capture, improve efficiency, and deliver clean energy through RNG projects. Our solutions help clients reduce emissions, generate revenue, and meet ambitious sustainability goals.
