  • Clean Earth appears on Engineering News-Record’s (ENR) annual Top 200 Environmental Firms list for 11th consecutive year, ranking in the Top 30 for the first time.
  • Harsco Environmental makes list for the second year in a row, ranking #27.

CAMP HILL, Pa. – (July 27, 2021) -  Harsco Corporation (NYSE: HSC), a global market leading provider of environmental solutions for industrial and specialty waste streams, today announced that its Clean Earth and Harsco Environmental divisions have been named to the Engineering News-Record (ENR) annual Top 200 Environmental Firms list, both ranking in the Top 30.

Clean Earth, one of the largest specialty waste processing companies in the U.S., placed #29 on the Top 200 list (jumping 19 spots from 2020) with more than $619 million in 2020 environmental revenue, and #7 on the Top 20 Hazardous Waste Firms ranking (up from #16 in 2020). Additional rankings include:

  • Top 10 Firms by Type of Work: Clean Earth placed #9 for Construction/Remediation, the first time the Company has been listed in the category.
  • Top 30 All-Environmental Firms: Clean Earth ranked as #8 for the first time.

In 2020, Harsco completed its largest acquisition, acquiring Stericycle’s Environmental Solutions business and integrating it with Clean Earth to create a leading U.S. hazardous waste treatment, disposal and recycling company. Harsco aims to make it easy for customers to properly and sustainably manage their difficult-to-treat waste, a task easier said than done. To address this gap in the market, Harsco’s Clean Earth division recently launched the Fullcircle™ Advanced Waste Lifecycle Program, a concierge service that carefully and strategically analyzes waste before it even happens.

Harsco Environmental, a premier provider of material processing and environmental services to the global steel and metals industries, placed #27 on the Top 200 list with $674 million in 2020 environmental revenue. ENR’s list is also broken down into multiple notable subcategories, where Harsco Environmental ranks #10 in the Top 20 Firms Working in Non-U.S. Locations and #5 on the Top 20 Hazardous Waste Firms ranking.

“We are incredibly proud to have two divisions named to this prestigious industry list,” said Harsco Chairman and CEO Nick Grasberger. “Harsco’s corporate vision is to be a global leader of environmental solutions by solving the biggest waste challenges of today. The accomplishments of Clean Earth and Harsco Environmental further support our pursuit of this goal every day, and our path towards providing customers with more sustainable solutions.”
