Islanders are being encouraged to reuse and recycle pumpkins after Halloween.
Guernsey Waste said a “scary amount” of waste was produced at the end of October every year.
It said the pieces of flesh removed when carving pumpkins could be used in recipes such as pumpkin lasagne, spicy pumpkin soup and autumnal pumpkin tart.
The company said the more fibrous flesh from around the seeds could be home composted or put into the food waste caddy, along with the carved pumpkin.
Waste minimisation and sustainability officer Douglas Button said islanders bought thousands of pumpkins each year to carve or for decoration.
But h said the “best – and tastiest- parts of the pumpkin” were often forgotten and ended up being thrown away.
Islanders are also being asked to think about the number of single-use plastics they consume during Halloween, from sweet wrappers to costume items.
Mr Button said decorations and costumes could be reused in following years which also helped to save money.
He added: “Through a few small steps, people can have fun at Halloween while limiting any negative impacts on the environment.
“It’s all about trying to reduce, reuse and recycle as much as we can.”
