The health of wildlife populations is shaped by everyday environmental management decisions that take place far from national parks and conservation areas. One of these decisions concerns how organic waste from agriculture, food systems and settlements is handled. When this waste is poorly managed, it can carry disease-causing organisms into landscapes shared by livestock, wildlife and people. For this reason, waste management forms part of the broader conversation about biosecurity.
This issue has become particularly visible during recent outbreaks of Foot and Mouth Disease (FMD) in southern Africa. FMD is a viral disease that affects cloven-hoofed animals, including cattle, sheep, goats and buffaloes. It spreads through direct contact between animals, contaminated equipment and infected biological material. When organic waste from livestock operations or food processing enters open environments, it can contain microorganisms that remain viable for extended periods under certain conditions. If this material is accessible to animals or enters soil and water systems, it may contribute to the circulation of pathogens across agricultural and ecological boundaries.
In areas where livestock farming exists alongside conservation landscapes, this interaction requires careful management. South Africa’s conservation economy relies on both agriculture and wildlife tourism, and therefore, maintaining strong disease control measures remains essential for ecological stability and economic security. Waste management practices, therefore, need to consider not only environmental cleanliness but also the biological risks associated with decomposing organic material.
Enclosed in-vessel composting (IVC) has emerged as a useful technology in this context because it manages organic waste within a controlled system. Unlike open waste heaps or windrow composting, in-vessel composting processes organic material inside sealed units where temperature, aeration and moisture can be monitored. This controlled environment changes the biological conditions under which decomposition takes place.
In a BiobiN, as microorganisms break down organic material, temperatures inside the vessel typically rise to between 55°C and 70°C, which reduces many disease-causing organisms commonly present in organic waste streams, including bacteria such as Salmonella and Escherichia coli. Maintaining these temperatures for an appropriate period helps ensure that biological material is stabilised before it leaves the composting system.
Containment also plays an important role. Organic waste that decomposes in open environments can attract scavenging animals and birds, which may carry contaminated material into surrounding areas. In regions where wildlife and livestock share space, this movement can introduce pathogens into animal populations that would otherwise not encounter the waste source. Because in-vessel composting systems operate as enclosed units, they limit direct access to decomposing material and therefore reduce the likelihood of animals interacting with potentially contaminated waste.
For landscapes that support both agriculture and wildlife, these forms of containment contribute to responsible environmental management. Composting technologies that control temperature, prevent animal access and manage runoff allow organic waste to be processed safely before it returns to the soil as compost.
