As urbanisation increases, so does the challenge of meeting water, sanitation and food requirements in urban areas. In particular, the management of human excreta from on-site sanitation facilities remains a challenge and continues to endanger public health and degrades the environment through soil and water pollution. Yet much of the excreta consi...
