ReGenEarth, a company dedicated to creating and managing sustainable renewable energy and circular economy processes, is launching a £100 million Green Bond Programme in partnership with circular economy energy specialists RER. The bond programme aims to fund the implementation of innovative biochar generation technologies into existing anaerobic digestion (AD) and biomass plants in order to maximize pricing in the voluntary carbon credit markets.
The official launch of the Green Bond will take place at the Institute of Engineering & Technology in London on Tuesday, June 10 at 6pm. The event, which will feature partners BeZero and Onnu, as well as research partner Brunel University’s Chemical Engineering Department, will also discuss carbon credits, carbon capture, and Brunel’s SeaCure CO2 capture project.
This bond issuance offers investors in green bonds and sustainability opportunities an alternative to the saturated solar and wind market. By converting organic waste into renewable energy and valuable products like biochar, ReGenEarth promotes resource efficiency and environmental sustainability, contributing to a greener economy and reducing waste while also sequestering carbon in the UK.
The Bonds will be issued by RER Capital PLC, a special purpose financing vehicle (SPV) specifically created to finance businesses in the circular economy and CleanTech sectors. RER Capital PLC will direct capital towards enterprises that prioritize resource efficiency, waste reduction, and sustainable innovation, in alignment with the ICMA Green Bond Principles.
The proceeds from the Bonds will be secured against hard assets, including existing AD sites, and lent to a wholly-owned subsidiary of ReGenEarth on the date of issuance. This three-year Bond will pay a coupon of 12.5% and is due in 2030.
Biochar, a form of organic carbon, is produced through a process called pyrolysis, which heats organic matter in a low-oxygen environment. It has proven value for soil regeneration, water retention, and carbon sequestration, making it a valuable tool in mitigating climate change by reducing greenhouse gas emissions. Its porous structure also helps retain nutrients, making fertilizers more effective, and supports crop resilience by enhancing soil’s water retention capacity. Additionally, biochar fosters beneficial soil microbes, promoting ecosystem health and crop yields.
ReGenEarth is collaborating with industry pioneers in the biochar space, including Onnu, a trusted partner in the development of biochar solutions. Together, they are pioneering innovative solutions that harness the power of biomass to create cleaner, more sustainable energy.
Mickey Rooney, CEO of ReGenEarth, says, “We’re turning waste into climate wealth, making pyrolysis cool. With 12.5% returns and the ability to lock carbon away for centuries, this offers fertile ground for crop, climate, and cash generation. The question you should ask yourself is, why wouldn’t you want to be a part of it?”
