biosolids
UK: ˈbaɪəʊˌsɒlɪdz | US: ˈbaɪoʊˌsɑːlɪdz
n. Treated organic waste materials, often derived from sewage or agricultural byproducts, used as fertilizer or soil conditioner.
The term "biosolids" emerged in the late 20th century as an environmental science neologism, combining "bio" (highlighting the organic, life-derived nature of the material) and "solids" (emphasizing its processed, non-liquid state). This rebranding aimed to distinguish treated, safe waste products from raw sewage, reflecting advancements in waste management and recycling. The word’s construction follows modern scientific naming conventions, where Greek and Latin roots are fused for precision and neutrality.
Farmers increasingly use biosolids to enrich soil without chemical fertilizers.
The wastewater treatment plant converts sewage into stable biosolids.
Strict regulations ensure biosolids meet safety standards for agricultural use.
Critics argue that biosolids may contain trace contaminants harmful to ecosystems.
Research shows biosolids improve crop yields by enhancing soil fertility.
