US Department of Energy recognition for the heat-retention contribution of the patented hexagonal floating cover, validating its energy-efficiency case on hot wells and digesters.
DOE recognition refers to US Department of Energy acknowledgement of the patented hexagonal floating cover’s heat-retention contribution. The cover reduces surface heat loss by 60–80%, delivering measurable energy savings on hot wells, mesophilic anaerobic digesters, and warm process water storage. DOE recognition is part of the validation history that distinguishes the original patented product.
