Every day, human activities generate large amounts of solid waste. To ensure the quality of the environment, waste must be further treated to prevent it from accumulation in landfills. In the case of materials that cannot be recycled or reused, such as municipal solid waste, burning in waste incineration plants to generate heat or electricity appears to be the appropriate solution of such waste disposal. However, combustion processes generate residues, such as bottom or fly ash, which must be stored. Fly ash gener...

In contemporary agricultural practice, ensuring sufficient bioavailable macronutrients, particularly phosphorus, for plants in phosphorus-deficient soils remains a significant challenge.
