Case studies

Independently verified results from floating cover deployments across the EU and beyond.

• biogas · Netherlands (anonymised — biogas operator named under NDA) · 1,800 m² (digestate storage; digester core under continuous membrane)

  31% reduction in mesophilic digester heating input over winter operating period

  “We expected the cover to help with odor on the digestate storage. We didn't expect the digester heating budget to fall as much as it did — the warm digestate radiating into the storage shed had been a much bigger heat-loss path than we'd modelled.”

• mining · Chile (anonymised — operator named under NDA) · 22,000 m²

  92% evaporation reduction measured over 12 months

  “The covers paid back within 18 months on water savings alone, and the dust complaints we'd received for years simply stopped after the first deployment week.”

• wastewater · Germany (anonymised — Stadtwerke named under NDA) · 8,500 m²

  91% odor (H₂S) reduction measured at boundary sensors over 6 months

  “Community complaints went from 47 in the prior 12 months to zero in the 6 months after deployment. The covers paid for themselves in regulatory headroom alone.”
