Results of Comparative LCA Study show Euro Manganese’s Battery-Grade Manganese Products have Lowest Carbon Footprint

GlobeNewswire December 8, 2022

VANCOUVER, British Columbia, Dec. 07, 2022 (GLOBE NEWSWIRE) — Euro Manganese Inc. (TSX-V and ASX: EMN; OTCQX: EUMNF; Frankfurt: E06) (the “Company” or “EMN”) is pleased to announce positive results from a Life Cycle Assessment study comparing the global warming potential (“GWP” or “carbon footprint”) of the Company’s high-purity manganese products from the Chvaletice Project (“Chvaletice” or “the Project” or “CMP”) in the Czech Republic with those produced by the incumbent industry in China ÔÇô where currently 95% of global high-purity manganese products are processed.


  • The GWP of high-purity electrolytic manganese metal (“HPEMM”) produced at Chvaletice, using 100% renewable power, is 64% lower than the estimated GWP of HPEMM produced by the incumbent industry.
  • High-purity manganese sulphate monohydrate (“HPMSM”) produced via EMM dissolution has a carbon footprint 59% lower at Chvaletice compared to HPMSM produced in China.
  • Additional Company analysis shows that Chvaletice’s high-purity manganese metal has a significantly lower carbon footprint compared to nickel and cobalt, the other NMC battery cathode metals.

Details of the Life Cycle Assessment

Euro Manganese engaged Minviro Ltd. (ÔÇ£MinviroÔÇØ), a UK-based and globally recognized sustainability and life cycle assessment consultancy, and RCS Global Ltd. (ÔÇ£RCS GlobalÔÇØ), a leading global auditor of battery material supply chains, to conduct a cradle-to-gate study to evaluate the GWP of HPEMM and HPMSM produced at the Chvaletice Project and by the incumbent industry in China. Data analyzed was from public sources for different operational manganese plants in the country. GWP processing routes using both grid mix electricity and renewable electricity were evaluated in-line with LCA best-practice and Global Battery Alliance requirements for the battery passport.

Total 17.1 13.4 6.1 5.1 4.7 2.1

Note: Totals may not add exactly due to rounding.

  • Scope 1: direct Greenhouse Gas (“GHG”) emissions.
  • Scope 2: indirect GHG emissions from imported energy (electricity, heat or steam).
  • Scope 3: any other indirect emissions. This study excludes the transport of reagents for comparative purposes; as such, Scope 3 and total GWP figures for the CMP are slightly lower in this study than those detailed in the LCA Study conducted earlier this year.

The main contributors to the estimated carbon footprint of HPEMM produced in China are the embodied emissions from the electricity grid mix. For HPMSM produced in China via EMM dissolution, the main contributor is the same: embodied emissions in the electricity grid mix.

Summary of Processing Routes analyzed in Life Cycle Assessment

  Processing Route Location Purity
(% Mn)

Se-free electrowinning (Estimate) China 99.9
Se-free electrowinning (Grid Mix) CMP 99.9
Se-free electrowinning (Renewable Mix) CMP 99.9

EMM dissolution China >32
HPEMM dissolution (Grid Mix) CMP ~32.4
HPEMM dissolution (Renewable Mix) CMP ~32.4

The purity of Chvaletice’s HPMSM exceeds the published Chinese specification, as impurities in Chvaletice’s HPMSM process are controlled to a tighter level. Chvaletice’s and Chinese HPMSM products have manganese levels above 32%, however, HPMSM produced in China contains selenium (if using EMM produced in China as feedstock) while Chvaletice’s HPMSM is selenium free. HPMSM produced in China using ore from South Africa has higher levels of trace elements of fluorine and silicon compared to Chvaletice’s HPMSM.

Additional Company analysis of the GWP for different cathode metals shows that Chvaletice manganese has the lowest kg CO2 eq. per kg of metal when compared against the Nickel Institute LCA and Cobalt Institute LCA.

Dr. Matthew James, President & CEO of Euro Manganese, commented:

ÔÇ£The results of this comparative Life Cycle Assessment confirm that high-purity manganese products from the Chvaletice Project are shown to have a significantly lower carbon footprint than the incumbent industry. These results are also lower than other manganese projects that have recently published Life Cycle Assessment results. Equally, when benchmarked against the carbon footprint of nickel and cobalt, the other battery cathode metals, manganese from Chvaletice also compares very favorably. This further supports the move to high-manganese cathode chemistries, with manganese being the most affordable and green battery metal.

With automotive manufacturers increasingly using strategic procurement to meet their targets of lower carbon emissions, and as we progress offtake discussions, the results of this comparative Life Cycle Assessment are extremely beneficial and very timely.ÔÇØ
