Journal ArticleDOI
Assessing amendment and fertilizing properties of digestates from anaerobic digestion through a comparative study with digested sludge and compost
Fulvia Tambone,Barbara Scaglia,Giuliana D'Imporzano,Andrea Schievano,V. Orzi,Silvia Salati,Fabrizio Adani +6 more
TL;DR: The results showed that digestates differed from ingestates and also from compost, although the starting organic mix influenced the digestate final characteristics, and appears to be a very good candidate to replace inorganic fertilizers, also contributing, to the short-term soil organic matter turnover.
Journal ArticleDOI
Odours and volatile organic compounds emitted from municipal solid waste at different stage of decomposition and relationship with biological stability.
Barbara Scaglia,V. Orzi,Adriana Artola,Xavier Font,Enrico Davoli,Antoni Sánchez,Fabrizio Adani +6 more
TL;DR: Results obtained indicated that odours and VOCs emitted depend on the biological stability of waste measured by the dynamic respiration index (DRI) and a very good correlation were found between these parameters.
Journal ArticleDOI
Short-term experiments in using digestate products as substitutes for mineral (N) fertilizer: Agronomic performance, odours, and ammonia emission impacts.
C. Riva,V. Orzi,Marco Carozzi,Marco Acutis,G. Boccasile,S. Lonati,Fulvia Tambone,Giuliana D'Imporzano,Fabrizio Adani +8 more
TL;DR: Digestate and derived products, because of high biological stability acquired during the AD, had greatly reduced olfactometry impact, above all when they were injected into soils, and ammonia emission data indicated that the correct use of digestate andderived products required their injection into the soil avoiding, ammonia volatilization into the air and preserving fertilizer value.
Journal ArticleDOI
Solid and liquid fractionation of digestate: Mass balance, chemical characterization, and agronomic and environmental value.
TL;DR: Chemical characterization suggested that the LF can be used as a substitute for mineral N fertilizers because of its high N content, while SF can be proposed as an NP-organic fertilizer.
Journal ArticleDOI
Potential odour emission measurement in organic fraction of municipal solid waste during anaerobic digestion: Relationship with process and biological stability parameters.
V. Orzi,Erasmo Cadena,Giuliana D'Imporzano,Adriana Artola,Enrico Davoli,M. Crivelli,Fabrizio Adani +6 more
TL;DR: The results obtained indicated that the stabilization of the treated material reduces the odour impact measured by the olfactometric approach, and OD20 reduction could be used as an odour depletion indicator.
