Do some of your holiday lights need to be replaced? Please consider purchasing LED lights. They use 95% less energy than conventional lights - and they last longer! Oh - and remember that the old lights that don't work anymore need to be thrown out in the garbage. Sorry, they aren't recyclable (regardless of what the packaging indicates).
The reason why is because they become tangled in the sorter. Everything stops while workers tackle the tangled mess. This makes recycling slower and more expensive. So, when in doubt - throw it out!
