Sadiq Mohammed, Charles Mulenga and Russel Morkel (not in the photo) successfully completed their PhD studies despite the interruption caused by Covid-19 and the difficulties that followed, and graduated in December 2022. Sadiq Mohammed investigated the feasibility of manufacturing wood plastic composites from invasive trees and recycled plastic to be used as building materials in the Reconstruction and Development Programme (RDP) houses. Charles Mulenga analysed the effect that mining pollution has on the growth characteristics of indigenous trees in the Copperbelt area. Russel Morkel determined the moisture loss of wood logs during rail transport from the plantation to the mill. Well done guys – we are proud of you! ​
