RadTech Releases Findings on Compostability of UV/EB Cured Coatings on Compostable Substrates

Press release submitted on behalf of RadTech.

RadTech, Chevy Chase, Maryland, the association for UV & EB Technology, shared the results of its comprehensive compostability study, conducted with the Composting Manufacturing Alliance (CMA). The report examines the impact of ultraviolet (UV) and electron beam (EB) curing coatings on certified compostable substrates. The study provides key insights into how these technologies influence the end-of-life outcomes of coated and printed materials in industrial composting environments.

Kelly Williams of Green Key Group notes:

  • EB Technology Consistently Passes Compostability Screening: EB-cured coatings and inks demonstrated strong compatibility with industrial composting conditions, reinforcing their potential for use in compostable packaging applications.
  • Further Research Required for UV Systems: The study revealed that UV-cured materials exhibit varied disintegration results, indicating the need for deeper investigation into their biodegradation properties and formulation improvements.
  • The Future of Sustainable UV and EB Systems: Ideally, we are developing UV and EB systems from natural materials that can be wholly or partially assimilated versus hoping that synthetic options do not negatively impact the End-of-Life outcome.
