The effluents of an unhairing-liming workshop of a craft tannery in North Cameroon are exposed to a gliding arc discharge for various exposure times in a cold plasma reactor. The highly basic effluent is rich in concentrated organic wastes which are degraded by the oxidizing species formed in the discharge. Total Organic Carbon (TOC) and Biological Oxygen Demand (BOD5) abatements by 95% and more than 90% respectively result from one hour treatment in batch conditions. Simultaneously pH trends to acid. Bacterial inactivation was also found successful for short exposures t*<10 min. The feasibility of the plasma technique is then confirmed in case of actual effluents at the laboratory scale and may be developed in view of industrial applications by valuable improvements.
