Ghana, a West Africa country, is deeply burdened by poverty, and relies on the production of gold for economic sustainability. The gold mining companies in the country have international origins and receive most of their requirements from international sources. The extraction of gold from the crushed ore requires sodium cyanide as a lixiviant, which is imported into Ghana from other countries in wooden intermediate bulk containers (IBC) for further distribution to the mines. A life cycle assessment was completed to determine the burden that this packaging, which includes the wooden container and polyethylene and polypropylene liners, places on the environment in Ghana when disposed of. It was found that the life cycle of the incinerated IBC impacted on the Ghanaian environment the most, due to the incineration and the transportation of the IBC. The International Organization for Standardization 14040 management standard was used as a methodological framework for the assessment. === Environmental Science === M.Sc. (Environmental Science)
