Plastic recycling has lightened some of the environmental burden of disposal, but the majority of plastics are landfilled or incinerated after a single use; the US plastic-bottle recycling rate is less than 25 percent, according to the American Plastics Council. Even if we raised that percentage, recycling plastic isn’t an ideal solution; the plastic we recycle doesn’t turn into more of the same kind plastic we tossed into the bin, but has to become lower-quality plastic that has limited applications, such as plastic lumber.
