UTILISATION OF GREEN WASTE FROM MINE OVERBURDEN THROUGH BIO-ELECTROCHEMICAL SYSTEMS

Abstract

ABSTRACT. Proper management of overburden materials can reduce the environmental impact and increase the benefits of mining activities. It is important to consider the specific composition of the overburden and local needs when selecting the most appropriate recovery method. And while much of the overburden material can be used in construction, reclamation, cement production and more, the green waste problem has not been sufficiently solved. In the present publication, the possibilities of generating energy from the green waste from the overburden through bio-electrochemical systems are investigated. The possibilities of generating energy from grass, wood chips and leaves have been studied. The best results were achieved in grass utilisation, generating a power density of 107,58 mW/m2.
