US Patent 11851813 Surface coverings including carbon sequestering materials and methods of making

Floor coverings, such as modular panels or tiles, for installation on interior surfaces include one or more layers, for example, an upper wear layer and a backing layer, where at least one layer includes a filler that includes a carbon negative material, such as concentrated carbon. The carbon negative material can sequester carbon such that the resulting floor covering has a negative carbon footprint when subjected to a Life Cycle Assessment.
