Midland Resource Recovery (MRR) is North America’s leading specialist in natural gas odorization and mercaptan handling. Since 1996, MRR has supported utilities, pipeline operators, and renewable natural gas (RNG) developers with the technical expertise required to safely design, install, operate, and maintain odorization systems.

Our work focuses on one of the most critical elements of gas infrastructure: ensuring that natural gas is safely detectable and that odorant systems operate reliably and in full regulatory compliance. From greenfield RNG projects to legacy natural gas infrastructure, MRR provides both field services and engineered solutions that help operators manage risk, maintain compliance, and ensure consistent odorization performance.

MRR’s capabilities include pipeline conditioning (pickling), odorizer installation and commissioning, temporary odorization systems, mercaptan handling and transfer, system maintenance, equipment decommissioning, and emergency spill response. We also supply specialized products such as odorization equipment, activated carbon filtration systems, and odor control solutions designed specifically for gas utility and RNG applications.

With facilities across north America, MRR supports clients across North America. Our team is recognized for its deep technical knowledge, strong safety culture, and practical field experience working with complex odorization systems.

For RNG developers and operators, MRR provides reliable odorization solutions that integrate seamlessly with biogas upgrading systems and pipeline injection infrastructure, helping projects meet safety, compliance, and operational requirements from commissioning through long-term operation.
