Utilize Heavy Metal-Contaminated Farmland to Develop Bioenergy

摘要

Currently, the World confronts with several major problems, including environment pollution and energy shortage. To utilize metal-contaminated soils safely and to solve the problem of shortage of farmland for bioenergy development, we have postulated a new strategy of cultivating energy plants in Cd-contaminated soils for bioenergy production, and this can also be combined with phytoremediation. Here, we focus on the advantage and feasibility of this approach by a review of recent developments in basic and applied research relevant. It is concluded that cultivation of energy plants in metal-contaminated land for bioenergy production is a high beneficial, environment-friendly technique that is also technically feasible. It might not only cover the shortages of phytoremediation and bioenergy production, but also makes the metal-contaminated land fully utilized and productive, and this is benefited for both agriculture and farmers.
