TLDR
In this paper, the authors proposed a methodological framework to assess the nitrogenous emissions by coupling technological performances of spreader and biophysical models, focusing on sewage sludge spreading in different weather and soil conditions.Abstract:
Organic waste land application generates nitrogenous emissions that have impacts on acidification, eutrophication and global warming To assess these impacts with Life Cycle Assessment, emission factors are commonly used without taking into account neither the type and performance of land application techniques nor the type of organic waste applied This paper proposes a methodological framework to assess the nitrogenous emissions by coupling technological performances of spreader and biophysical models, focusing on sewage sludge spreading in different weather and soil conditions The first step consists of creating several spreading scenarios by combining a cropping system and a “spreader/sewage sludge” couple The second step consists of testing the technological spreader performances regarding spatial distribution, application rate and soil compaction with a spreading simulator and the COMPSOIL model Nitrogenous emissions are then simulated with STICS and DEAC models for different application rates and soil bulk densities Finally, the simulated nitrogen losses from the models are linked with the real amounts of sewage sludge applied and the compacted soil due to spreader performances Our approach shows that ammonia emissions during sewage sludge spreading can be directly linked to the spreader performances whereas nitrate leaching depends more on the soil and on the weather conditions Nitrous oxide emissions mostly depend on the spreader weight and to the soil and the weather conditions This method paves the way to new approaches: integrating technological performances of machines into biophysical and agricultural models in order to assess environmental impacts of agricultural practicesread more

Sewage sludge as fertiliser - environmental assessment of storage and land application options.
TL;DR: Systems with autumn application are preferable to spring application for all impact categories but, when nitrate leaching is considered, spring application is preferable in terms of eutrophication and primary energy use and, for some SS treatments, GWP.

Environmental performances of production and land application of sludge-based phosphate fertilizers—a life cycle assessment case study
TL;DR: Assessment of whether fertilizing with sludge-based phosphate fertilizers (SBPF) can be a suitable alternative to doing so with fertilizers produced from phosphate rock highlighted that production and land application of SBPF had higher environmental impacts than those of TSP due to the large amounts of energy and reactants needed to recover P.
