The present invention relates to a field of chemical engineering and in particular to a method for continuously pelletizing water-soluble solids, comprising steps of: a) feeding raw material and seed particles to a pelletizing disc; b) pelletizing water-soluble solids during wetting with an aqueous phase; c) removing pelletized product from the pelletizing disc; d) drying the pelletized product from step c); e) dividing the dried pelletized product from step d) into fractions; e) removing the commercial fraction from the process, characterized in that in step e), the dried pelletized product from step d) is divided into four fractions: a commercial fraction having a pellet diameter in the range of D.sub.1 to D.sub.2; a coarse fraction having a pellet diameter>D.sub.2; a recycled fraction having a pellet diameter in the range of

[00001]$\frac{D_1+D_2}{9}$

to D.sub.1; and a fine fraction having a pellet diameter in the range of

[00002]$<\frac{D_1+D_2}{9};$

wherein the recycled fraction is fed as the seed particles to the raw material feeding step a), the coarse fraction is fed for grinding to a particle diameter in the range of

[00003]$\frac{D_1+D_2}{9}$

to D.sub.1 and then recycled to the process at the raw material feeding step a), the fine fraction is fed for grinding until there are no pellets having the size exceeding the particle size of the raw material, and also recycled to the raw material feeding step a), wherein the raw material particle diameter is

[00004]$<\frac{D_1+D_2}{44}.$

A method for capturing material extracted from biochar, the method comprising the steps of: (i) providing a biochar; (ii) contacting the biochar with a treating liquid, where the treating liquid causes the removal of solids from the pores and surface of the biochar, thereby creating a resulting solution or extract comprised of the treating liquid and removed solids; and (iii) collecting the resulting solution or extract. The method further comprises the step of apply the resulting solution or extract to soil or for use in other applications.

A system for nutrient remediation in a water environment using biologically active bioremediation units (BABUs), comprising a biologically active first compound of sodium alginate with chitosan, mixing a quantity of glomalin and lignin with Chlorella vulgaris to form a second mixture, mixing the first mixture with the second mixture, and spherifying the third mixture by dropping the third mixture into calcium chloride, creating a physical medium to contain the viable culture of the remediating organism called BABUs, and where the BABUs are used for nutrient remediation in a surface water environment where the surface water environment contains an excess of nutrients, waiting for nutrient capture by the BABUs, removing the nutrient rich BABUs from the water, and placing the BABUs in soil, wherein the BABUs release the nutrients to the soil.
