Heartwood Partners is pleased to announce that The Amlon Group (“Amlon” or “the Company”) has acquired Mastermelt America LLC. The facility, now operating as Amlon Sweetwater, specializes in processing and treating complex industrial waste streams, serving the chemical, pharmaceutical, electronics, aerospace, and power generation industries from its Sweetwater, Tennessee location. The transaction closed in May 2025.
“The Mastermelt acquisition is a game changer for our business,” said Mark Wayne, CEO & President of The Amlon Group. “This facility brings critical capabilities in thermal processing and chemical dissolution of complex industrial materials. While our existing facilities excel at hazardous waste treatment and disposal, Sweetwater adds specialized processing capabilities for spent catalysts, electronic components, and aerospace materials – waste streams that require metallurgical and engineering expertise. This positions Amlon as a more comprehensive environmental solutions provider for our customers across multiple industries.”
Wayne continued, “Beyond the capabilities expansion, Sweetwater strengthens our geographic footprint in the Southeast, complementing our existing Texas and Louisiana operations. The facility’s advanced thermal processing and chemical dissolution capabilities, together with the team’s expertise in industrial waste streams, create immediate value for customers who need comprehensive waste processing solutions.”
“We’re excited to support Mark and the entire Amlon team in this strategic chapter of growth,” said Demetrios Dounis, Managing Partner, Heartwood Partners. “The Sweetwater acquisition demonstrates Amlon’s continued evolution from a pure-play waste treatment company into a platform that delivers comprehensive environmental solutions – expanding their processing capabilities to handle the most complex industrial waste streams across multiple industries. This acquisition aligns perfectly with our thesis that customers increasingly demand integrated environmental solutions from partners who can serve as their single-source provider for specialized waste treatment. We see significant runway for Amlon to build on this foundation and continue serving as the partner of choice for manufacturers who take their environmental compliance and sustainability commitments seriously.”
