August 21, 2024: Italian lead recycler and engineering firm STC has been selected to supply its mechanical vapour recompression (MVR) energy recovery technology to Estonian used lead battery recycler Ecometal.
STC confirmed to Batteries International on August 16 that is has been contracted to transform Ecometal’s existing system used for the crystallization of sodium sulfate solution obtained from the desulfurization of lead paste.
Upgrading the system to utilize MVR technology will result in a combined annual saving on natural gas consumption of about 5 million cubic metres and a reduction in CO2 emissions of about 3,000 tonnes annually, STC said.
Ecometal said the estimated cost of the project, set to be completed by August 2026, is €1 million ($1.1 million), for which it has received a grant of more than €394,000 from the European Regional Development Fund.
STC has installed MVR systems in separate projects in recent years including at all Monbat Recycling sodium sulphate crystallization plants in Bulgaria, Romania and Serbia.
