Answer:
Sewage sludge is a biodegradable way of recycling human waste
Step-by-step explanation:
What distinguishes "biosolid" in its use as fertilizer made from sewage sludge is because sewage sludge is a biodegradable way of recycling human waste. Sewage sludge is known to be a semi-solid material that is produced during sewage treatment. Biosolids are actually used as fertilizers due to the treatment the sewage sludge has undergone in order to make it fit for land use. In the process of manufacturing biosolids, certain processes are carried out in order to make it meet pathogen requirements for land application and surface disposal. These biosolid are biodegradable and that's one of the reasons why they are suitable as fertilizers.
