King of Prussia, Pa. – (April 21, 2022) – Clean Earth, a division of Harsco Corporation and a leading provider in environmental and regulated waste management services, announces that it has succeeded in recycling more than 8 billion pounds of waste last year, including several hard-to-treat specialty wastes, such as hazardous and non-hazardous waste, contaminated soil, dredge material, universal and e-waste. This recycled waste makes up 93 percent of the waste Clean Earth processed throughout 2021 and represents continued progress toward the goal of deriving 90 percent of Harsco Corporation’s revenue from environmental solutions.

Specifically, Clean Earth recycled:

  • 362 million pounds of hazardous waste

“Every day, we develop and implement innovative solutions to turn the world’s largest waste streams into recycling opportunities that positively impact our planet and the people who inhabit it,” said David Stanton, President of Clean Earth. “We are proud of our sustainability achievements in 2021 and look forward to continuing to strengthen and grow our capabilities.”

In 2021, Clean Earth expanded its service offerings in the hospitality and convenience store sectors, which will further increase the proportion of Harsco Corporation’s total revenue that comes from environmental solutions. With a broad range of environmentally responsible, flexible, and cost-effective solutions for customers in the hospitality and convenience store industries, Clean Earth is poised for further progress.
