Abstract
Tannins are a group of highly polar phenolic compounds present in natural extracts of plants. Due to their polar nature, tannins are easily extracted into industrial process wastewaters by simple contact of water with tannin rich agroindustrial feedstocks. Once present in industrial effluents, tannins can be regarded as environmental pollutants due to their highly toxic characteristics and in some cases they are persistent against biological degradation. Unlike other environmental pollutants biodegradation is not the sole route available for remediation since tannins are readily polymerized to nontoxic humic compounds that are essentially harmless to the environment.
