Heritage-Crystal Clean, Allonnia, Revive Environmental, and EPOC Enviro Launch 4never™, the First Full-Scale Closed-Loop PFAS Solution in the Market

This collaboration brings an end-to-end solution to separate, concentrate, transport, and
annihilate PFAS contamination from landfill and industrial waste management sites  

Hoffman Estates, IL, January 31, 2023 – Heritage-Crystal Clean Inc. (Nasdaq: HCCI), through its
wholly-owned subsidiary, a leading provider of environmental and industrial services, today
announces a new partnership with Allonnia, Revive Environmental, and EPOC Enviro to launch
4never™, the first closed-loop PFAS remediation solution, to the landfill and industrial waste
management markets.

PFAS, or per- and polyfluoroalkyl substances, is a group of chemicals known as “forever
chemicals” that have been used in a wide range of consumer and industrial products. Research
has shown that they have become pervasive in the environment and pose a health risk when
accumulated in the body, creating a need to safely destroy these contaminates while leaving no
harmful byproducts.

4never™ unites the PFAS remediation steps of separation, concentration, transportation, and
destruction to provide an effective and environmentally responsible solution for landfill
operators and the industrial market.

4never™ combines the power of Surface Active Foam Fractionation (SAFF®) technology,
exclusively distributed by Allonnia in North America and manufactured by EPOC Enviro, with
Revive Environmental’s PFAS Annihilator™ to provide a complete PFAS elimination process.
Heritage-Crystal Clean (“Crystal Clean”) is the exclusive distributor and operator of the 4never™
solution to the private landfill and industrial waste treatment markets, serving clients through
its nationwide network of branches and waste treatment facilities.

“Our joint vision begins with protecting the Earth’s resources. Providing a solution which
addresses a problem as pervasive as PFAS is a powerful execution of this vision,” said Crystal
Clean’s President & CEO, Brian Recatto. “The 4never™ solution offers landfill operators and
manufacturers a cost effective and compliant approach to managing PFAS contaminated
leachate and wastewaters.”

“Allonnia is proud to work with Crystal Clean and our technology partners, combining SAFF®
and PFAS Annihilator™, to create a solution for the North American market that permanently
destroys what has been labeled a forever chemical,” said CEO of Allonnia, Nicole Richards. “It is
impressive how the landfill market has embraced the PFAS removal challenge, and it’s been
incredible to work with other innovators passionate about solving our most challenging
environmental problems.” 

4never™ helps landfill operators and manufacturers improve their sustainability footprint by
removing and destroying PFAS prior to discharge to their local municipal wastewater treatment

The hub-and-spoke model begins with a SAFF® unit at the generating source. Crystal Clean will
provide, operate, and service the SAFF® unit, which separates and concentrates PFAS
contaminants from waste streams. Crystal Clean will then transport the separated PFAS hyper-
concentrate to one of its wastewater treatment facilities, where Revive Environmental’s PFAS
Annihilator™ unit will destroy the PFAS.

“Revive Environmental is excited to bring its patented, enabling technology to this partnership,”
said Revive Environmental President and CEO David Trueba. “The PFAS Annihilator™ is the
culmination of years of development and the leading way to completely destroy PFAS with the
confidence that can only be realized through world-class scientific research.”

Crystal Clean will also implement the SAFF® technology at its own commercial wastewater
treatment facilities to further concentrate other PFAS contaminated waste streams prior to
destruction using the PFAS Annihilator™. 4never™, the first of its kind, full scale, closed-loop
PFAS treatment solution will be offered by the consortium as a service, where customers will
pay a fixed cost per gallon.
