This research demonstrates an innovative approach to sustainable farming by connecting mushroom and lettuce production in a circular system. The study shows how waste material from mushroom growing can be repurposed for lettuce cultivation, creating an efficient and environmentally friendly farming method. Impacts on everyday life: • Provides small farmers with a cost-effective way to grow both mushrooms and vegetables • Reduces agricultural waste by recycling mushroom growing materials • Offers a sustainable method for producing healthy food locally • Demonstrates how circular farming practices can benefit small-scale agriculture • Shows potential for reducing dependency on commercial fertilizers
