Why Use External Salad Greens?

These external leaves serve as the plant’s natural wrapping, guarding the delicate inner leaves. While composting produce scraps is a basic sustainable practice, finding new uses for these parts is additionally impactful. Turning surplus food into rich soil prevents dump buildup, where it may release greenhouse gases, a potent climate concern.

This is rather innovative if you consider over it: produce rots and transforms into that ideal soil to nourish further crops, thus closing the loop and respecting the process of growth.

Yet, with more than 30% surplus produce getting made compared to required, consuming valuable resources wisely is crucial. Minimizing waste not only saves money but also promotes the increasingly eco-friendly lifestyle.
