Turning shell waste into marine life<\/h4>\n

ReefCircular is dedicated to restoring marine ecosystems by transforming shell waste into 3D-printed artificial reef structures designed to mimic natural habitats. The ReefKasse system, a modular artificial reef tile, can be easily installed on harbour walls and underwater structures, providing an ideal surface for marine organisms to attach and grow, helping to counteract habitat loss in urban coastal areas. In Hundested, Denmark, 24 artificial reef tiles have been installed to create complex habitats for small fish, seaweed, and invertebrates on seawalls and the seafloor. The installation process is efficient, taking as little as 30 minutes and requiring no dive teams, making it an accessible solution for biodiversity restoration. The system is currently being tested in clay, which has lower CO2 emissions than concrete, and will be available in shell-based bioconcrete from 2026.[\/vc_column_text][\/vc_column][vc_column width=”1\/2″][vc_single_image media=”94565″ media_width_percent=”100″ uncode_shortcode_id=”132920″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ back_color=”color-gyho” overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ content_parallax=”0″ uncode_shortcode_id=”192115″ back_color_type=”uncode-palette”][vc_column width=”1\/2″][vc_single_image media=”94564″ caption=”yes” media_width_percent=”100″ media_ratio=”four-three” lbox_caption=”yes” uncode_shortcode_id=”210370″][\/vc_column][vc_column width=”1\/2″][vc_single_image media=”94563″ caption=”yes” media_width_percent=”100″ media_ratio=”four-three” uncode_shortcode_id=”751634″][\/vc_column][\/vc_row][vc_row row_height_percent=”0″ overlay_alpha=”50″ gutter_size=”3″ column_width_percent=”100″ shift_y=”0″ z_index=”0″ content_parallax=”0″ uncode_shortcode_id=”284875″][vc_column width=”1\/3″][\/vc_column][vc_column width=”1\/3″][vc_single_image media=”94566″ media_width_percent=”90″ uncode_shortcode_id=”409711″][\/vc_column][vc_column width=”1\/3″][\/vc_column][\/vc_row]<\/p>\n<\/div><\/span>","protected":false},"excerpt":{"rendered":"
