The novelty of the BiAR process lays the complete conversion by solvolysis at moderate temperatures of ash-rich biomass and wastes to high-value ash-free pellets for energetic use. This is the only cost-efficient process able to separate inorganic from organics compounds at large scale.
Nowadays, the only method economically viable at industrial level to separate the inorganic compounds from organic compounds is burning. New emerging techniques are arising to reduce the biomass ash content; however, they are at an experimental stage. Due to the low percentages of separation, these techniques are not the solution for the efficient removal of ashes from biomass feedstocks. Moreover, none of these techniques are applicable to the range of biomass waste and residues types such as sludge and agro-forestry residues. As a result, ash-rich biomasses are currently being used ineffectively or still largely disposed. BiAR is the only economically viable process able to convert low value biomass waste and residues into highly value biomass for energetic use and with the lowest environmental impact.
