Deal Overview

MediWaste builds compact, automated treatment systems that destroy pharmaceutical compounds, chemotherapy agents, and other regulated medical waste on-site at hospitals and pharmacies. Current practice ships medical waste to distant incineration facilities—expensive, carbon-intensive, and creating chain-of-custody liability. MediWaste's systems use advanced oxidation to render waste non-hazardous in under 4 hours, reducing costs by 50% and eliminating transport risk. Installed at 120+ healthcare facilities across 22 states.

Key Highlights

  • Destroys pharma waste on-site in under 4 hours
  • 50% cost reduction vs offsite incineration
  • 120+ hospital and pharmacy installations
  • $14M ARR with 95% gross retention
