Interface has expanded its CQUEST backings line to include new styles. CQuestBioX, when combined with specialty yarns and proprietary tufting processes, results in a cradle-to-gate carbon-negative carpet tile. CQuestGB’s construction includes post-consumer recycled content from carpet tiles, bio-based additives, and preconsumer recycled materials. CQuestBio is a non-vinyl biocomposite backing made with bio-based and recycled fillers.
