Abstract

A method of recycling carpet into structural beams or sheet materials having a laminated structure (10), the method comprising the steps of stacking at least two sheets of carpet (16) on top of each other to form a stack and bonding the faces of adjacent sheets of carpet in the stack to one another using an adhesive (16), the said adhesive (16) comprising any one or more of the group comprising: PVA; an emulsifier; and polyurethane and, once cured, cutting (28) the resulting laminate to desired dimensions. The resulting laminated material can be used as a substitute for building materials such as MDF sheeting, wooden beams and the like. Optionally, a relatively open, shock-absorbing laminate (40) can be manufactured having a non-slip surface (46), which may be suitable for use as an equine walkway.
