E-waste is growing faster than any other type of waste with an annual volume close to 40 million metric tons globally. Plastic accounts for roughly 23% of all e-waste. Primarily this is acrylonitrile-butadiene-styrene (ABS) plastic which contains ultraviolet inhibitors and brominated flame retardants and is virtually nonbiodegradable. Recent advances in recycling technology allow for the recycling of e-waste ABS plastic into sheeting. A significant amount of testing has been conducted on ABS recycled plastic sheeting to support the possibility for use as a traffic sign substrate. The benefits to utilizing recycled ABS plastic sheeting versus aluminum as a traffic sign substrate include the following: ABS plastic sheeting would be far less theft prone than the current aluminum signs as it has less after-market value than aluminum; recycled ABS plastic sheeting would save costs because it is 35% less expensive than aluminum; and recycled ABS plastic sheeting has one quarter the carbon footprint as aluminum.
