Impact of Bottom Ash Addition on Pleurotus ostreatus Cultivation on Coffee Ground Substrate
This research explored using coal power plant waste (bottom ash) combined with spent coffee grounds to grow oyster mushrooms. The study found that small amounts of bottom ash (1-5%) could be safely used in mushroom cultivation while potentially improving certain nutrient levels in the mushrooms. This has several practical implications for everyday life: • Provides a new way to recycle both coffee waste and industrial ash waste • Could help create more sustainable and cost-effective mushroom cultivation methods • Offers potential solutions for improving poor quality soils using post-cultivation substrate • Demonstrates how waste materials can be transformed into valuable resources • Could lead to more environmentally friendly waste management practices in both industrial and agricultural sectors
