Are you looking to turn waste liabilities into revenue streams?
Whether you work in an industrial, municipal, or wastewater setting, the potential for renewable natural gas (RNG) is often an overlooked asset.
At RETTEW, our biogas experts partner with you to transform organic waste from an unavoidable expense into a profitable, sustainable energy source—renewable natural gas.
Transforming Organic Waste into Revenue and Resiliency
As your comprehensive biogas and RNG service provider, we help you uncover the dual benefits of biogas: producing RNG while meeting your ESG (Environmental, Social, and Governance) goals.
We’ll also collaborate with you to unlock specialized renewable gas financial opportunities with targeted carbon footprint reduction and consulting around methane capture.
Through the anaerobic digestion process, we help you manage all types of organic waste and emissions, including
- Manure
- Biosolids
- Organics
- Landfill gas
Full-Lifecycle Biogas Infrastructure Development
Your biogas project has a complex lifecycle and RETTEW partners with you from the initial budget all the way to your facility’s opening day with comprehensive EPC services.
Before committing major capital to a biogas infrastructure project, it is important to establish a structured, data-driven roadmap.
Serving as your dedicated project team, RETTEW will analyze market conditions, assess technical viability, and develop conceptual facility designs. In every project phase, our primary focus is to meet your technical specs within the parameters of your operational and financial goals.
Every biogas project has unique operational demands. During the engineering and design phase, we translate feasibility studies into fully realized plant designs.
From high-level design consulting to detailed blueprints for anaerobic digesters and processing plants, we ensure your facility has optimal energy recovery and long-term reliability.
Transitioning from the consulting, planning, and engineering phase to active construction requires reliable coordination. As your engineering, procurement, and construction (EPC) partner, we manage the entire facility build-out.
While specialized contractors will handle your physical build, we serve as your dedicated project manager from the initial bidding process and right-of-way acquisition through permitting, construction coordination, and final build inspection.
A successful facility requires more than project oversight in the build process—you need partners who can provide continuous support and strategic optimization.
In the final phase of the project, we transition from construction management to active operations, providing the continuous renewable gas infrastructure planning, management, and optimization you need to maintain quality and safety standards for years to come.
Biogas Upgrading Solutions
To maximize your return on investment, our multidisciplinary team will design the ideal gas-handling infrastructure for you based on an in-depth analysis of your facility and the economics of your local market.
Whether you need basic gas conditioning to power on-site operations or a comprehensive system to refine raw biogas into high-quality RNG for the broader market, we deliver the solutions to make it happen.
We build each gas processing system from the ground up to address your specific impurity profile, removing CO2, moisture, and hydrogen sulfide until your biogas meets pipeline-quality RNG standards.
Our specialized upgrading and renewable gas utilization services include:
- Direct pipeline injection: We design the infrastructure, interconnections, and metering systems to inject your RNG directly into the commercial natural gas grid.
- Virtual pipeline networks: When direct pipeline access is not viable, we develop the compression and transportation logistics to move your RNG to market via specialized trailers.
- On-site combined heat and power (CHP): Our team implements co-generation systems to convert raw biogas into electricity and thermal energy to power your facility and significantly reduce operational costs.
Biogas Regulatory Compliance Expertise
The current regulatory landscape is often the most complex and time-consuming part of the RNG process.
RETTEW’s team acts as your primary point of contact with local regulators to manage the intricate legal requirements and environmental approvals.
Our goal is to maintain rigorous compliance while also taking full advantage of the clean energy financial incentives currently available.
Our regulatory and compliance services include:
- Securing multi-level permitting: Managing the comprehensive documentation and submissions required to receive approvals on the local, state, and federal levels, including the Department of Environmental Protection (DEP).
- Navigating legal and environmental hurdles: Serving as your dedicated representative to eliminate regulatory roadblocks by resolving zoning issues and securing environmental clearances.
- Maximizing policy incentives: Providing decades of experience to help you monetize your renewable initiatives through Renewable Identification Numbers (RINs), the Low Carbon Fuel Standard (LCFS), and broader carbon credit markets.
- Conducting sustainability assessments: Evaluating the lifecycle of your project to ensure it remains within ESG goals and benchmarks common to your industry.
