Following on from our first article about the EU Salt Association Conference 2019, this one focuses on the two remaining areas:
Circularity and Salt
With increasing awareness and action being taken to arrest climate change and environmental damage, the role of salt in the circular economy was discussed at the conference. A frequent topic for discussion at previous conferences, the salt industry and British Salt has a strong track record of resource efficiency. British Salt re-uses 95% of the water used in the production of salt and tops up with rain-water collected at the production facility. Producing salt via the vacuum method uses heat and pressure generated using gas fired boilers. The six-stage evaporation process then re-uses the steam and pressure in each phase, meaning little of the energy used to generate the steam is wasted. British Salt also re-uses carbon dioxide produced when generating steam as an input to the production process in order to reduce the corrosive effects of brine on the production equipment by inhibiting rusting.
Two areas stood out in this part of the conference for Richard Diggle, Business Development Manager for British Salt. Firstly, a series of presentations on why the benefits of a low salt diet have been overstated for people other than those who suffer from hypertension. This goes against the grain of some health recommendations, but there is a growing body of evidence to support this position.
Secondly, salt has been used as an iodine delivery method to help treat iodine deficiency globally for many years. Despite this, there is a need to harmonise iodine concentrations on salt across Europe so that producers can supply the EU markets with compliant products across the continent. The recent Krakow Declaration was made by the EU Salt Association to promote harmonisation, so presentations on this topic followed the actions taken to date.
We’re already looking forward to the 2020 conference, if you’ve any questions about the two articles, please do get in touch!
