Montauk Renewables Announces Filing of Provisional
Patent Application for New Acid Neutralization Technology


PITTSBURGH, July 29, 2022 — Montauk Renewables, Inc. (“Montauk” or “the Company”) (NASDAQ:
MNTK), a renewable energy company specializing in the management, recovery and conversion of
biogas into renewable natural gas (“RNG”), today announced the Company has filed a provisional patent
application with the U.S. Patent and Trademark Office (USPTO) pertaining to a combustion based
oxygen removal condensate neutralization technology.

The patent application is directed to a new acid neutralization technology that is a critical and integral
component in eliminating the harmful acidic condensate that is produced when wastewater is removed
from the biogas conversion process. Without a mitigating measure, high acidity can result in expenses of
hundreds of thousands of dollars in damage associated with the processing facility components as well as
downtime for equipment replacement and troubleshooting. The Company has identified a successful
demonstration of a reduction in unfavourable pH condensate through the considerable testing that has
been completed to-date. The filing of this provisional patent application aligns to Montauk’s continued
efforts to deploy technology within the Company’s existing portfolio for landfill biogas recovery.

“We are excited to announce the provisional patent application for our innovative acid neutralization
technology,” said Sean McClain, Montauk Renewables CEO. “The patent application reflects Montauk’s
on-going commitment to technological innovation to stay ahead of market competitors and we are excited
about the advantages associated with this technology.”
