Closing the loop on responsible production

Saft operates the only plant in the world that produces nickel-cadmium batteries incorporating metals that have been reclaimed on site from spent batteries, reducing their eco-footprint.  Recycling Ni-Cd batteries is a complex process that involves separating the nickel, cobalt and cadmium from the electrodes, a process perfected by Saft’s plant in Oskarshamn, Sweden – the only one worldwide involved in both the recycling and manufacturing of Ni-Cd batteries and incorporating recycled metals.

Saft operates a network of over 30 bring back points worldwide that receive spent Ni-Cd batteries produced at Saft factories, as well as those made by its competitors. The bring back point located in northern Europe brings these used batteries back to Oskarshamn, minimizing transportation. Other bring back points work with other fully permitted recycling partners selected by Saft to ensure that the recovery rates mandated imposed by the EU battery directive are met.

Awards

Saft was awarded a top rating in 2021 by Ecovadis, a Corporate Social Responsibility (CSR) rating organization for sustainable development performance, scoring in the 96th percentile on: environment, labor and human rights, ethics, and sustainable procurement.

The new and enhanced Sunica.plus is a perfect example of Saft’s commitment to supporting sustainability through innovative approaches to effective and reliable renewable energy schemes. We have now taken Sunica.plus to the next level with four important improvements:

1. The number of capacity steps is extended to 36, so it now covers the range from 50 Ah up to 1830 Ah.
2. The interval for topping-up with water is increased to 6 years (at 1.50 V).
3. Higher cycling capability, up to 10000 cycles at 15% of Depth Of Discharge during the 20-year service life.
4. There is a significant impro-vement in charge efficiency that makes more capacity available for each daily cycle – now up to 95% when the capacity is stabilized.

Effective energy storage for standalone installations: A wide variety of remote safety critical installations worldwide rely increasingly on solar PV systems for cost-effective and environmentally responsible power.
