A technology integration approach for optimising biohydrogen production from food waste
Published in Frontiers in Fuels
Dark fermentation of food waste for biohydrogen production is a progressive technology that can contribute to low-cost solutions to the global clean energy need. As dark fermentation research progresses, it is important to evaluate opportunities for real-life application such as integration into existing anaerobic digestion systems. The present stu...
Potential for improving nutrient use efficiencies of human food systems with a circular economy of organic wastes and fe...
Published in Environmental Research Letters
Waste from the human food system includes a large quantity of nutrients that pose environmental and human health risks. If these nutrients can be captured and repurposed, they could potentially offset synthetic fertilizer demands. This study reviews several technologies—including anaerobic digestion, hydrothermal carbonization (HTC), and composting...
Exploration of Optimum Configurations of Electro-Assisted Anaerobic Digester for Sulfate-Reducing Conditions: Significan...
Sulfides generated from sulfate reduction commonly act as inhibitors in anaerobic digestion (AD). This study examined the performance of three configurations of microbial electrolysis cell-assisted anaerobic digestion (MEC-AD) systems: single-chamber, dual-chamber with an anion exchange membrane (AEM), and dual-chamber with a cation exchange membra...
Occurrence of 40 sanitary indicators in French digestates derived from different anaerobic digestion processes and raw o...

Published in Frontiers in Microbiology
This study investigated the sanitary quality of digestates resulting from the mesophilic anaerobic digestion (AD) of urban and agricultural organic wastes (OWs). 40 sanitary indicators, including pathogenic bacteria, antimicrobial resistance genes, virulence factor genes, and mobile genetic elements were evaluated using real-time PCR and/or droplet...

Vil2Bio: Combining village-scale biogas production with pyrolysis in biomass stoves for off-grid sustainable clean cooki...
...
Future sustainable energy systems should be affordable and adapted to the local context, while also preserving natural resources such as forests, water and soil. The Vil2Bio project aims at integrating low-cost biochar, biogas, and solar photovoltaic technologies into a village-scale off-grid hybrid energy system providing energy for cooking, while...
Multicriteria analysis of sustainable agri-food waste management for an agroecosystem in Finland
Published in Frontiers in Sustainable Food Systems
Introduction The reliance on fossil inputs of agricultural practices has led to maximizing yields and profitability, even at the expense of environmental sustainability. Implementing circular waste management solutions could help align the economic and environmental goals of farmers while reducing their reliance on fossil inputs. The co-application...

Impacts on water quality of producing biogas on pig farms as a function of the associated agricultural practices
Published in Environmental Research Communications
The aim of this study was to assess positive or negative impacts of anaerobic digestion (AD) on water quality using a systemic approach. To this end, we used the agro-hydrological model Topography-based Nitrogen Transfer and Transformation (TNT2), a spatially explicit model that simulates nitrogen and water flows at the watershed scale on a daily t...
