1. Exergy and emergy: complementary tools for assessing the environmental sustainability use of biosolids generated in wastewater-treatment plant for energy-production
Taking advantage of the energy contained in the biosolids generated in a wastewater treatment plant (WWTP) is one of the processes of greatest interest due to the opportunity to obtain an energy resources from a waste. The aim of this research was to analyze the environmental sustainability use of biosolids generated in a wastewater-treatment plant for energ

2. Mapping of areas suitable for the application of biosolids in the Quadrilátero Ferrífero region, Minas Gerais, Brazil
Abstract The recovery of degraded areas is imperative for the sustainability of mining activities. The main action implemented to improve the chemical, physical and biological conditions of soils, tailings and sterile deposits is the incorporation of organic material. Biosolids (hygienized sewage sludge) are among the organic materials that can be applied. H

3. Leaching of Heavy Metals in Soils Conditioned with Biosolids from Sewage Sludge
ABSTRACT A promising use of biosolids is as organic fertilizer in agricultural and forestry activities. However, its composition might contain several pollutants, especially heavy metals, which may result in an increase in the concentrations of these elements in the soil and the risk of groundwater contamination. This study aimed to determine the leaching le

6. Economic and Financial Analysis of Tree Seedling Production Using Composted Biosolids Substrate
ABSTRACT The aim of this study was to evaluate production profitability of Croton urucurana and Cytharexyllum myrianthum seedlings produced in substrates composed of mixtures of composted biosolids and carbonized rice husk in different concentrations of nutrient solution. Seedlings were subjected to three doses of fertigation solutions. In order to check qua

7. Influence of film coefficient during multicomponent diffusion – KCl/NaCl in biosolid for static and agitated system using 3D computational simulation
Abstract The influence of film coefficient formed during the diffusion of inorganic salts (NaCl and KCl) in biosolids was studied using a 3D computer modeling by Finite Elements Method (FEM) in COMSOL Multiphysics® software combined with SOM-type Artificial Neural Networks (ANN). Such tools have shown that the influence of the film formed in the biosolid/s

9. Effectiveness of Five Biosolids as Nitrogen Sources to Produce Single and Cumulative Ryegrass Harvests in Two Australian Soils
ABSTRACT Biosolids have been produced by various stabilization processes of sewage sludge, but little attention has been given to the effects of such treatments on their effectiveness to supply nitrogen for plant growth. Here, we investigated these effects by cultivating Lolium perenne (ryegrass) in two Australian soils, a sandy Spodosol and a clayey Oxisol.

11. Evaluación de la mineralización de biosólidos de plantas de tratamiento de aguas residuales domésticas
The biosolids from wastewater Treatment plants have high potential of agricultural application due to the contents of organic matter and nutrients. The mineralization of biosolids from the Cañaveralejo Wastewater Treatment Plant, Cali-Colombia, was evaluated by fitting regression models. The content of NH4+, NO3- and NO2- were monitored during 126 days for

12. The efficiency of concentration methods used to detect enteric viruses in anaerobically digested sludge
The presence of enteric viruses in biosolids can be underestimated due to the inefficient methods (mainly molecular methods) used to recover the viruses from these matrices. Therefore, the goal of this study was to evaluate the different methods used to recover adenoviruses (AdV), rotavirus species A (RVA), norovirus genogroup II (NoV GII) and the hepatitis
