摘要： Methods, compositions, single-phase aqueous solutions, process mixtures, and kits are provided relating to recycling a pressure-sensitive adhesive laminate using a single-phase aqueous solution. For example, a method of recycling a pressure-sensitive adhesive laminate may include providing the single-phase aqueous solution. The single-phase aqueous solution may include water and a surfactant composition. The method may include providing the pressure-sensitive adhesive laminate. The pressure-sensitive adhesive laminate may include: a facestock including a label surface and an adhesion surface; a release liner including a release surface; and a pressure-sensitive adhesive coated on the adhesion surface of the facestock, the release surface of the release liner being laminated to the adhesion surface of the facestock through the pressure-sensitive adhesive. The method may include contacting the single-phase aqueous solution and the pressure-sensitive adhesive laminate to form a process mixture under conditions effective to provide a recycled portion of the pressure-sensitive adhesive laminate.

摘要： Methods, compositions, single phase aqueous solutions, process mixtures, and kits are provided relating to recycling a fibrous surface covering, e.g., carpet, using a single-phase aqueous solution. For example, a method of recycling a fibrous surface covering may include providing the single phase aqueous solution. The single phase aqueous solution may include water and a surfactant composition. The method may include providing the fibrous surface covering. The fibrous surface covering may include: a fibrous surface layer; a first backing coupled to the fibrous surface layer; and a binder coupled to one or more of the first backing and the fibrous surface layer. The method may include contacting the single phase aqueous solution and the fibrous surface covering to form a process mixture under conditions effective to provide a recycled portion of the fibrous surface covering.
