Cultivation of Energy Crops in Constructed Wetlands for Wastewater Treatment: An Overview

Detalhes bibliográficos
Resumo:The need for sustainable, clean, and secure energy sources is a current issue for all nations. All kinds of vegetal biomass can be used as energy-source or as raw material for biofuel production, but some species are commonly classified as energy crops. This work evaluates the energy potential of 35 species of energy crops when produced in constructed wetlands (CW). Producing energy crops in CW is a route to link wastewater treatment to energy production, avoiding the abstraction of freshwater for crop irrigation, and simultaneously avoiding the use of arable land. However, for most of the energy crops, there are no data available in the literature about biomass productivity in CWs. Although 20 of the 35 crops have been tested as CW vegetation, the biomass productivity in CWs was only found for 13 species. Reported biomass productivity in CW is similar to or even higher than the productivity reported for conventional production, but most reported data is for pilot-scale CW, which points to the need for future work in full-scale systems. From the combination of biomass productivity and the biomass calorific value, Arundo donax, Miscanthus x giganteus, Cynodon dactylon, Phragmites australis, and Typha latifolia show higher ranges up to 3064 MJ/ha year for Arundo donax. Future works on CW design can be focused on the potential of using energy crops as vegetation.
