In 2016 the biogas and biodiesel project were the main focus as the team investigated the feasibility of using biodigesters for energy by building digesters as well as the use of waste cooking oil to produces biodiesel. One successful digester lies in Muldersdrift, west of Johannesburg where a small scale farmer uses biogas from cow dung for cooking, lighting, and to run a geyser and generator. Another biogas project is in its starting phase in Joe Slovo community in Port Elizabeth. In 2016 Ewb projects continued to monitor the biodigesters installed in 2015 and also embarked on a biodiesel project using waste cooking oil. The project is complete and is ready to be implemented at community level. Some of the projects including the biogas and biodiesel projects have also been used to assist students with Work Intergrated Learning. The team also attended the Scifest and Sasol expos to try and showcase what they are doing in communities. EWB-Unisa is still working on the essential oils projects where we are still trying to extract more oils form essential leaves via simple extractive distillation.
