Abstract: 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.

Abstract: Various embodiments of a system for coating removal are provided. In one embodiment, a system for removing a coating material from another material is provided, the system comprising: a staging hopper; a second elevator operatively connecting the staging hopper to the decoating mill; a decoating mill having a decoating mill tank and at least one rotary blade oriented within the decoating mill tank, wherein the at least one rotary blade can translate horizontally and vertically; a screen station having a dump hopper and a recovery tank; a washer; a dryer; an aspirator; a large waste water filter press; at least one process water filter press; a sanitary water filter; a staging tank; a water heater; and a process chemical feed system.
