A key sustainability challenge for anyone involved in commissioning, designing or manufacturing wayfinding signs, is to think well beyond day one. To future -proof and lengthen the operational life of the information, by really exploring what the likely requirements will be in 2, 5 or 10 years’ time and factoring these into the design. All the while recognising that at some point, the scheme will have outlived its useful life and designing sign forms so that component materials can be easily recovered to be recycled or repurposed.
