Livelihood and long-term sustainability
RETTEW specializes in helping our clients understand and keep track of all the various applications, permits, reporting, legal requirements, and processes for environmental compliance. But we don’t just hand you the paperwork and walk away. We help build a management system to set up your company’s environmental standards and sustainability processes, including monitoring, reporting, recordkeeping, and training.
You’re busy running your business, not keeping abreast of the latest policies and regulations. That’s our job. The myriad of federal, state, and municipal codes can be confusing to navigate, and is continually evolving and changing. The experts at RETTEW help you understand and manage the regulatory requirements that are applicable to your operation.
Staying compliant

With 30-plus years of experience in environmental compliance, we are well-versed in on-site investigations, assessments, and remediation. We work with a variety of industries, including pharmaceutical, chemical, primary and secondary metals, and food and beverage.
Beyond that, RETTEW’s environmental, health, and safety (EHS) experts know that any good business plan includes compliance standards – training, risk management, auditing, and performance goals. We regularly develop custom templates for environmental improvement and sustainability across single and multi-site client facilities – addressing concerns from energy efficiency and waste minimization to water conservation and greenhouse gas emission reduction.
Environmental Compliance in practice
RETTEW helps organizations manage their EHS risks by developing and implementing systems tailored to each client. Many of these management systems are ultimately certified to international standards such as ISO 14001 and ISO 45001. So, when one large food provider needed help with their environmental compliance system, they called us. Because EHS can get complicated really quickly, and some things can easily slip through the cracks, we provided a gap analysis. This gave the company’s leadership a comprehensive glimpse inside each area and helped prioritize improvements. The gap analysis also showed the need for change management around health and safety. We worked to change the mindset and culture around compliance to make it a forethought rather than an afterthought.
Many of our clients have multiple facilities in various states and sometimes other countries. RETTEW’s experts have assisted these clients in setting up management systems that provide a consistent framework for managing EHS compliance and risks while also continually improving EHS performance across the entire organization.
A large but niche pharmaceutical company asked for RETTEW’s help in navigating the ins and outs of their carbon footprint, including robust energy use, wastewater, manufacturing pollutants, sterilization waste, hazardous lab wastes, air emissions, and vehicle emissions. Similarly, a nearby bourbon manufacturing company turned to RETTEW for help in planning their water use, residual waste, barrel disposal, flammable waste, and air emissions. Both clients relied on our expertise, experience, and relationships to act as a third-party inspector, and to complete permitting work and more.
