REC Group claims least expensive carbon impact for silicon
- Tiny polysilicon producer REC Solar Norway has actually asserted a carbon footprint of 11.2 kg CO2-eq per kg silicon, which was validated by EPD Norway and released Environmental Product Declarations (EPDs) for solar grade silicon and for multicrystalline silicon blocks made by REC.
REC Solar Norway, formerly Elkem Solar and also a subsidiary of REC Group, is stated to have an annual production capacity of greater than 8,000 MT, relating to around 2.5 GW of PV module production.
The company uses a specific metallurgical filtration approach to generate polysilicon that is asserted to minimize energy consumption by 75%, contrasted to the Siemens process. The 'modified' Siemens procedure likewise decreases product wastage and also boosted power usage, while Fluidized Bed Reactor (FBR) technology additionally decreases energy usage over the changed Siemens procedure.
REC's EPDs are created according to Product Category Rules (NPCR 029-- v1.1) handled by EPD Norway as well as are produced based upon a Life Cycle Evaluation (LCA), which is in turn accomplished in accordance with appropriate ISO criteria and standards, according to REC Group.
In General, REC Group claimed that its polysilicon had the most affordable environment effect of any kind of solar quality silicon product being created today.
