The following timelapse video (and appropriate musical accompaniment) produced by Jon Emmerich details the installation of marmoluem flooring in the form of interlocking tiles. According to Forbo, a leading manufacturer of marmoleum, this type of flooring is comprised of 97 percent natural materials, 72 percent of which are renewable within 10 years. Of the total content, 43 percent is recycled. Marmoleum is also 100 percent non-toxic and biodegradable.
