Öppen föreläsning: Biochar - for sustainable use of organic waste in agriculture and forest ecosystems

Post doc forskare Ali Muhammadi vid Karlstad universitet undersöker miljöeffekterna och vilka ekonomiska möjligheter som finns med att använda fast avfall från massa- och pappersbruken för att producera biokol och bioenergiprodukter som alternativt användningsområde för biomassan.

Biochar produced from waste are enriched with ash and some minerals in a pelletized form. Then, the enriched biochar pellets would be applied in forest ecosystems as an organic fertiliser.

Ali received his PhD from University of New England (Australia) in 2017. His PhD project focused on biochar-bioenergy systems, mainly assessing the environmental performance of biochar production for application to paddy fields as a soil amendment. He has modelled pyrolysis technologies which generate recoverable energy as well as biochar, at different scales ranging from small household units to large bioenergy power plants. His work found that converting biomass into biochar and mixing it with soil significantly mitigates the climate-change effect of rice cropping systems through carbon sequestration and suppression of soil greenhouse gas emissions compared with baseline scenarios. These results could improve understanding of biochar as an effective strategy to reduce global warming by its recalcitrant carbon storage in soil.
