Biochar urinals use biochar to capture nitrogen from animal and human urine. The biochar absorbs nitrogen which can then be used as fertilizer for plants. These urinals provide an environmentally friendly way to capture nutrients from waste and produce biochar bricks that can be used in green building materials.
