Circular Economy in the Management of Wastewater Treatment Plant: A Business Model Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT The water and wastewater management sector faces many challenges related to the implementation of a circular economy (CE). To date, sectoral CE solutions have focused mainly on technological innovations, with limited attention paid to social and economic aspects.

Sustainable Phosphorus and Protein Recovery from Different Organic Wastes: Process Optimization and Struvite Precipitation Potential

Agronomy
Currently, researchers are exploring alternative phosphorus sources for agricultural production that are more sustainable than rock phosphate. In this context, the recovery of phosphorus from organic wastes as struvite can constitute an important tool ...

Nutrient recovery from deammonification effluent in a pilot study using two-step reject water treatment technology

Water Resources and Industry, 2021
The aim of this study was to assess the possibility of phosphorus and nitrogen recovery from the liquid fraction of digestates (reject water) pilot study using a two-step technology, where the precipitation of biogenic compounds in the form of magnesium ...

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

Sustainable Development, EarlyView.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Nutrient Removal and Recovery: Hazenite Precipitation From Livestock Manure Wastewater

Water Environment Research, Volume 98, Issue 8, August 2026.
This study presents an optimized precipitation process for complex livestock wastewater, achieving > 90% concurrent removal of phosphorus, magnesium, and ammoniacal nitrogen. The system successfully drives targeted Hazenite (KNaMg2(PO4)2.14H2O) crystallization, recovering essential nutrients into a high‐value, slow‐release agricultural fertilizer ...

Simulations and Laboratory Tests for Assessing Phosphorus Recovery Efficiency from Sewage Sludge

Resources, 2018
Phosphorus is a potential environmental pollutant, which could lead to the eutrophication of water bodies. For this reason, wastewater treatment plants worldwide are often designed and operated to eliminate phosphorous from effluents, at substantial cost.

Phosphate Recovery from Swine Wastewater by a Struvite Precipitation Electrolyzer [PDF]

Scientific Reports, 2019
AbstractStruvite precipitation electrolyzers are interesting environmental electrochemical reactors with potential applications for efficient phosphate recovery from wastewater, such as swine wastewater. In this paper, effects of phosphate concentration and pH on the struvite precipitation reaction rate were investigated.
