MedClean Technologies, Inc. Approved in New Jersey

Garden State Hospitals Can Now Enjoy MedClean Guaranteed Saving Program

Approval Follows Joint Authorization Process by NJ Department of Environmental Protection and NJ Department of Health and Senior Services

BETHEL, Conn., May 12 /PRNewswire-FirstCall/ — MedClean Technologies, Inc. (OTC Bulletin Board: MCLN), a provider of innovative technology and services for onsite treatment and disposal of regulated medical waste (RMW), today announced that it has been approved to proceed with sales and installation efforts in N.J. following a joint authorization issued by the state Department of Environmental Protection and Department of Health and Senior Services.

The authorization was the culmination of an extensive review process during which MedClean executives and industry consultants collaborated closely with senior members of both N.J. departments. The approval enables Garden State hospitals to enjoy MedClean’s program of guaranteed savings on costs for off-site hauling and treatment of regulated medical waste (RMW), sharps and HIPAA-compliant confidential document destruction. The state of New Jersey has one of the most rigorous review processes and this is the first such approval for an on-site hospital system granted since 2005.

“With the opening of MedClean’s N.J. office in Scotch Plains last year, we are poised to deliver proven savings and safe, compliant services to the state’s hospitals,” said Scott Grisanti, President and CEO of MedClean Technologies, Inc. “MedClean’s strong value proposition is built on expense reduction, risk mitigation, and environmental protection for host communities. We look forward to implementing the MedClean On-Demand Series of turnkey containerized systems, along with traditional in-house systems, to hospitals that desire efficacious, reliable, cost effective solutions for on-site treatment of RMW and HIPAA-compliant confidential document destruction.”

Mr. Grisanti continued, “As a lifelong resident of N.J., I am grateful for the opportunity to serve our state’s healthcare community and am thankful for the thorough and thoughtful process employed by the Department of Environmental Protection and the Department of Health and Senior Services.”
