Biogas production transforms organic matter into methane, carbon dioxide and ammonia (NH3). The aim of this study was reducing NH3 emissions from liquid effluents of agricultural anaerobic digesters. An alternative to classic nitrification-denitrification ...
Sustainable development is an issue that is gaining more and more relevance in all areas of society, though specifically in industry. In order to move towards the goal of sustainability, life cycle thinking is an essential element. For the implementation o ...
Composting (aerobic treatment of organic wastes) and digestion (anaerobic treatment of organic wastes combined with biogas production) are important waste management strategies with increasing significance in the European Union and Switzerland. Most of the ...
Material flow management has become an increasingly important paradigm in waste management. An essential goal of this paradigm is prioritizing waste reduction over reuse and recycling, and the latter waste management processes over secure disposal of waste ...
In Europe, 9.3 x 10(6) t(dry weight ( dw)) of compost and digestate are produced per year. Most of this is applied to agricultural land, which can lead to considerable inputs of organic pollutants, such as polychlorinated biphenyls ( PCB) and polycyclic ar ...
Justification In Sub-Saharan Africa, excreta and wastewater disposal is characterised primarily by on-site sanitation systems. This sanitation option is more likely to increase as governments, municipalities, communities, private operators and donor agenci ...
This study is the first thorough method optimisation for accelerated solvent extraction (ASE) of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from chemically dried compost. For PCBs, optimised solvent composition, temperatur ...
This study compares six wastewater sludge treatment scenarios applied to a 300,000 equivalent-inhabitant (eq. inh) wastewater treatment plant: agricultural spreading, fluidised bed incineration, wet oxidation, pyrolysis, incineration in cement kilns and la ...
Compost and digestate are important recycling fertilizers and have beneficial effects on soil parameters. However, they can contain significant amounts of organic pollutants. Here, the first comprehensive data set on dibenzo-p-dioxins and -furans ( PCDD/F) ...
Aerobic granular sludge-based reactors represent an attractive alternative to conventional activated sludge systems due to their small footprint and their low energy consumption and excess sludge production. The granules developed in such systems have high ...
