abstract = {Sugarcane bagasse is commonly combusted to generate energy.
Unfortunately, recycling strategies rarely consider the
resulting ash as a potential fertilizer. To evaluate this
recycling strategy for a sustainable circular economy, we
characterized bagasse ash as a fertilizer and measured the
effects of co-gasification and co-combustion of bagasse with
either chicken manure or sewage sludge: on the phosphorus
(P) mass fraction, P-extractability, and mineral P phases.
Furthermore, we investigated the ashes as fertilizer for
soybeans under greenhouse conditions. All methods in
combination are reliable indicators helping to assess and
predict P availability from ashes to soybeans. The
fertilizer efficiency of pure bagasse ash increased with the
ash amount supplied to the substrate. Nevertheless, it was
not as effective as fertilization with triple-superphosphate
and K2SO4, which we attributed to lower P availability.
Co-gasification and co-combustion increased the P mass
fraction in all bagasse-based ashes, but its extractability
and availability to soybeans increased only when
co-processed with chicken manure, because it enabled the
formation of readily available Ca-alkali phosphates.
Therefore, we recommend co-combusting biomass with
alkali-rich residues to increase the availability of P from
the ash to plants.},
