Up to half a billion plastic plant pots are ending up in landfill or incineration plants every year, even though councils have been instructed to collect them for recycling.
A study by Horticulture Week found only nine out of 75 local authorities sampled had a recycling scheme for plastic garden waste in place. Guidelines state that all plant pots, except the non-recyclable black variety, should be picked up in roadside collection.
This means millions of pots are likely to be left to decompose in waste sites. On average, it takes around 450 years for single-use plastic items, like bottles and nappies, to biodegrade in landfill – that’s five times the life expectancy of the average person. And black plastic is one of the worst culprits because it’s dyed with carbon inks that cannot easily be broken down.
