Method for Zero-Waste Circular Economy Using Worms for Plastic Agriculture: Augmenting Polystyrene Consumption and Plant Growth

Urban Farm DB summary

This study investigated using mealworms and superworms to consume polystyrene (PS) and their frass as plant fertilizer. Researchers found that small amounts of sucrose and bran increased PS consumption by the worms. Superworm frass, in particular, supported better growth and rooting of dragon fruit cacti over a fortnight compared to mealworm frass and control media. These findings suggest worms could offer a zero-waste solution for plastic degradation and urban farming.
