Biobased fertilisers from fishery side-streams: an environmentally friendly alternative to mineral fertilisers? 

ReLEAF partners FiBL and ISQ have published a new study examining whether bio-based fertilisers produced from fishery side-streams can provide an environmentally preferable alternative to mineral fertilisers. The study assessed three fertilisers made from different fishery residues: pellets produced from fish sludge, a solid fertiliser made from fish frames and heads, and a liquid fertiliser derived from fish viscera. Their environmental impacts were compared with those of mineral fertilisers using Life Cycle […]

ReLEAF pilot in Vienna explores how food waste can become bio-based fertiliser 

As part of the ReLEAF project, partner AERIS has recently installed a pilot bioreactor at the project’s technical demonstration site in Vienna, the Kleine Stadtfarm. The installation marks an important step in testing how locally generated food waste can be transformed into bio-based fertilisers directly where it is produced.  The bioreactor, developed by AERIS, will be used to test a process based on solid-state fermentation […]
