A collaboration between our subsidiary Sparks AS, Jacobi Group and Norwegian steel producer 7 Steel Nordic shows how a single change in air filtration can deliver measurable environmental results.<\/strong><\/p>\n Our subsidiary Sparks AS<\/a> has been featured in the latest edition of A Pure World, the industry publication of the Jacobi Group<\/a>. The article highlights a long-standing collaboration between Sparks, activated carbon manufacturer Jacobi Group, and 7 Steel Nordic<\/a> \u2014 one of the leading reinforcing steel producers in the Nordic region \u2014 that has led to an estimated annual CO\u2082 reduction of 1,000 tonnes [1].<\/p>\n 7 Steel Nordic operates a steelworks in Mo i Rana, near the Arctic Circle in northern Norway, where recycled scrap iron is converted into reinforcing steel. The facility runs on hydropower and is regarded as one of the cleanest steel production sites in the world.<\/p>\n Steel production inevitably releases harmful substances such as mercury and dioxins into the air. To capture these pollutants, the plant uses filters filled with activated carbon \u2014 a highly porous material that traps contaminants as gases pass through it. And it was exactly this part of the process where Geir Markussen, partner at Sparks AS, saw an opportunity to do things differently.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.6″ _module_preset=”default” width=”90%” custom_margin=”25px||5px||false|false” custom_padding=”0px||0px||true|false” border_color_all=”#FFE600″ global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/08\/7-steel-norwegen.webp” alt=”steel production in Norway” title_text=”7-steel-norway” show_in_lightbox=”on” use_overlay=”on” overlay_icon_color=”#FFFFFF” hover_overlay_color=”rgba(60,60,59,0.2)” hover_icon=”.||divi||400″ _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”||on||||||” text_font_size=”15px” custom_margin=”||30px||false|false” global_colors_info=”{}”]<\/p>\n 7 Steel Nordic’s steelworks in Mo i Rana is one of the cleanest steel production facilities in the world | \u00a9 7 Steel Nordic<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/08\/alter-stahl.webp” alt=”scrap iron” title_text=”scrap-iron” show_in_lightbox=”on” use_overlay=”on” overlay_icon_color=”#FFFFFF” hover_overlay_color=”rgba(60,60,59,0.2)” hover_icon=”.||divi||400″ _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”||on||||||” text_font_size=”15px” custom_margin=”||30px||false|false” global_colors_info=”{}”]<\/p>\n Scrap iron is turned into some of Europe’s most sustainable reinforcing steel | \u00a9 7 Steel Nordic<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.27.4″ _module_preset=”default” width=”90%” custom_padding=”0px||0px||true|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.7″ _module_preset=”default” custom_margin=”20px||||false|false” global_colors_info=”{}”]<\/p>\n When tightened Norwegian emission limits put pressure on 7 Steel Nordic’s existing filtration system, Sparks and Jacobi worked with the company to replace the conventional coal-based activated carbon in the filters with a coconut-based alternative. This coconut-based carbon has roughly half the carbon footprint of its coal-based counterpart, resulting in an estimated reduction of around 1,000 tonnes of CO\u2082 per year. To put that into perspective: you could drive a car for 4.35 million kilometres before emitting the same amount.<\/p>\n On top of the emissions reduction, the new material has also proven more durable in the filters, meaning fewer production shutdowns for maintenance. A significant cost saving for the steelworks.<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_2,1_2″ _builder_version=”4.27.6″ _module_preset=”default” width=”90%” custom_margin=”25px||25px||true|false” custom_padding=”0px||0px||true|false” border_color_all=”#FFE600″ global_colors_info=”{}”][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/08\/kokosnuss.webp” alt=”coconuts” title_text=”coconut” _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”||on||||||” text_font_size=”15px” custom_margin=”||30px||false|false” global_colors_info=”{}”]<\/p>\n Coconut shells \u2014 the renewable raw material behind the activated carbon used in 7 Steel Nordic’s filtration system. | \u00a9 Jacobi Group<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/08\/aktivkohle.webp” alt=”coconut-based active carbon is used in air filtration” title_text=”active carbon” _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font=”||on||||||” text_font_size=”15px” custom_margin=”||30px||false|false” global_colors_info=”{}”]<\/p>\n Coconut-based activated carbon: The porous granules trap harmful pollutants such as mercury and dioxins from the air. | \u00a9 Jacobi Group<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row admin_label=”Line” _builder_version=”4.27.4″ _module_preset=”default” width=”90%” custom_padding=”0px||0px||true|false” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.7″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n “Reducing 1,000 tonnes of CO\u2082 from a single product in our production process is significant,” says Per Johan H\u00f6gberg, Environmental Manager at 7 Steel Nordic Manufacturing.<\/p>\n Olaf Brastad, Senior Adviser at the Bellona Environmental Foundation (a Norwegian non-profit organisation dedicated to developing sustainable industry solutions) calls the achievement “a significant milestone for the entire industry” and “an excellent example of what can be achieved through targeted cooperation.”<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,1_4,1_2″ admin_label=”Line” _builder_version=”4.27.6″ _module_preset=”default” width=”90%” custom_margin=”35px||35px||true|false” custom_padding=”20px|20px|20px|20px|true|true” border_width_all=”2px” border_color_all=”#FFE600″ global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/04\/ds-icon-gelb-zahnraeder.svg” title_text=”ds-icon-gelb-zahnraeder” admin_label=”Bild” _builder_version=”4.27.6″ _module_preset=”default” max_width=”90px” module_alignment=”left” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font_size=”15px” global_colors_info=”{}”]<\/p>\n <\/p>\n Coconut shells, a renewable by-product of the coconut industry, are cleaned, dried and crushed<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/04\/ds-icon-gelb-pellets.svg” title_text=”ds-icon-gelb-pellets” _builder_version=”4.27.6″ _module_preset=”default” max_width=”90px” module_alignment=”left” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font_size=”15px” global_colors_info=”{}”]<\/p>\n <\/p>\n The shells are heated at low temperatures to remove moisture and volatile components, producing coconut shell charcoal.<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/ds-bremen.de\/wp-content\/uploads\/2026\/08\/ds-icon-gelb-dampf.svg” title_text=”ds-icon-gelb-dampf” _builder_version=”4.27.6″ _module_preset=”default” max_width=”90px” module_alignment=”left” global_colors_info=”{}”][\/et_pb_image][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” text_font_size=”15px” global_colors_info=”{}”]<\/p>\n <\/p>\n The charcoal is passed through high-temperature kilns with a controlled flow of steam.
