The Chang Robotics Fund Announces Strategic Investment in REA Systems, an Innovator in Wastewater-to-Energy Technology

REA is flipping the script on brown grease, and the Chang Robotics Fund is helping convert waste into watts.

The Chang Robotics Fund is proud to announce a strategic investment in REA, a company transforming the wastewater industry by converting hazardous brown grease into a valuable, clean energy asset. This investment underscores our commitment to backing solutions that solve critical infrastructure challenges while delivering significant environmental and economic returns.

The world’s 86,000 wastewater treatment plants face a massive and costly challenge: managing the billions of gallons of fats, oils, and grease (FOG) that enter our sewer systems. This "brown grease" leads to sanitary incidents and costs municipalities over $25 billion annually to manage through environmentally harmful and inefficient methods like incineration and landfilling.

REA directly confronts this challenge with its patented Total FOG Solutions® platform. This fully automated, onsite system converts brown grease into an ASTM-grade biodiesel. The successful pilot program in Connecticut, has already proven the technology's effectiveness, demonstrating the ability to transform waste into a valuable clean energy asset that can be sold commercially or used to power the facility itself.

Our decision to invest in REA is grounded in a clear and compelling thesis:

• Unrivaled Technology & IP: REA possesses the only fully operational, patented system of its kind, creating a significant competitive moat and establishing clear market leadership.

• Transformative Financial Model: The platform converts a significant operational expense for treatment plants into a revenue-generating asset. This powerful economic incentive is a key driver for rapid adoption.

• Clear Path to Market & Exit: By solving an essential infrastructure problem, REA is an ideal acquisition target for major players in the water and energy sectors, offering a clear potential exit for investors.

• Proven Leadership: The company is led by industry veteran Al Barbarotta, whose expertise is critical for scaling operations and securing new municipal contracts.

"The CR Fund allows us to focus on the advancement and deployment of our technologies while leaning on the knowledge and skill of Chang Robotics for the development and management of our projects" — Al Barbarotta, General Manager and Founding Partner of REA

This investment will accelerate REA’s growth, funding the expansion of its technology portfolio and the development of several new wastewater projects slated for 2026.
