Abstract

Worldwide trends in the area under coca crops cultivation have been primarily motivated by illegal advances in Colombia around cocaine production. Thus, alternative ways for the final disposal of cocaine are needed and the evaluation of their possible economic and environmental advantages. This work aimed to compare incineration and biological degradation of cocaine by considering techno-economic and environmental aspects. There was a cocaine removal efficiency of 99.7% when bacterial C1T consortium was grown using cocaine as the sole carbon source. The biological degradation process exhibited a specific energy consumption and total potential environmental impact, 5 and 10 fold lower than the incineration process, respectively. The biological degradation process can also reach similar disposition unit prices as the incineration process (i.e., 1.00 USD/kg).
