Recycling of Biomass Ashes - Current Technologies and Future Research Needs -- Phosphorus Fertilizing Effects of Biomass Ashes -- Mixtures of Bottom Wood Ash and Meat and Bone Meal as NPK Fertilizer -- Wood Ash Effects on Soil Fauna and Interactions with Carbohydrate Supply: A Mini-Review -- Characterization of Olive Waste Ashes as Fertilizers -- Effects of Ash Applications on Soil Status, Nutrition and Growth of Pinus radiata D. Don Plantations -- Possible Use of Wood Ash and Compost for Improving Acid Tropical Soils -- Ash from Combustion of Cacao Residues for Nutrient Recycling: A Case Study -- The Use of Biomass Combustion Ashes in Brick Making -- Reuse of Woody Biomass Fly Ash in Cement-based Materials: Leaching Tests -- The Swedish Ash Programme with Focus on Bio-ashes. Ashes are a Resource in a Sustainable Society. The use of renewable bioenergy is increasing, and so is the production of associated wastes: biomass ashes. This book presents eleven chapters on the options for recycling such biomass ashes, ranging from their use as fertilizer in agriculture and forestry to their application as a supplement for the production of cement-based materials or bricks. The book also examines the pros and cons for each of the different uses of biomass ashes.
