Pumpkin waste: three ways to stop your leftover lantern becoming a Halloween horror story

Approximately 18,000 tonnes of pumpkins will be wasted in the UK this Halloween, with half of the 30 million purchased going uneaten. This amounts to £27 million worth of edible food. The waste of pumpkins also leads to the squandering of water, energy, and labor used to grow and distribute them. Additionally, the decomposition of pumpkins in landfills emits methane, a potent greenhouse gas.
