Biorefinery of inorganics [electronic resource] : recovering mineral nutrients from biomass and organic waste / edited by Erik Meers ... [et al.].

館藏資訊

Nutrient Recycling provides a comprehensive overview of the potential for mineral recovery from wastes, addressing technological issues as well as economic, ecological and agronomic / full-scale field assessments. In the introduction, the concept of using anaerobic digestion as a biorefinery for production of an energy carrier (biomethane) in addition to mineral secondary resources is explained, and subsequent chapters discuss the current state of mineral fertilizer use throughout the world, presenting an overview of the current resource availability and energy intensity. Technical aspects of mineral recovery organic (waste-)streams is explained, reviewing state-of-the-art and emerging technologies as well as (standardized) analytical characterization of biobased secondary resources and full-scale validation of biobased mineral products as substitutes for fossil-based counterparts. Later chapters go on to discuss regulatory aspects, the economics involved and ecological assessment in detail, and the book concludes with consideration of future perspectives and emerging trends. Nutrient Recycling will serve as a comprehensive reference work for experts in the field as well as providing teaching material for future experts specializing in environmental technology sectors.

摘要註

"As part of the move towards a bio-based economy, it is important to recycle the valuable nutrients that currently end up in waste streams. Nutrient resources are depleting and significant amounts of fossil energy are required for the production of synthetic fertilizers, but waste streams including agricultural waste, wastewater/sewage and municipal waste are significant sources of nutrients. The production of biogas through anaerobic digestion also produces nutrient-rich digestates, which have the potential for use as green fertilizers in agriculture"--
