Thermochemolysis of winery wastewater particulates-Molecular structural implications for water reuse

► Use of pyrolysis to characterize the molecular structure of particulates. ► Desorbable components closely resemble macromolecular fragments. ► Effluent particulates enriched in lignin and microbial reworked compounds. ► No evidence found for the accumulation of anthropogenic chemicals. ► High resistance to biodegradation has disposal implications.
