This research shows how waste products from biogas production can be recycled to grow more nutritious mushrooms. The scientists found that adding processed biogas waste to wheat straw significantly improved both mushroom yields and their nutritional content. This sustainable approach helps manage waste while producing healthy food. Impacts on everyday life: – Provides a way to produce more nutritious mushrooms for consumption – Helps reduce environmental waste by recycling biogas byproducts – Creates more sustainable and efficient food production methods – Improves the economic value of agricultural waste products – Demonstrates practical applications of circular economy principles
