step closer to separating waste at source
Municipalities across South Africa are considering implementing
separation of recyclable waste at source. A number of municipalities across
South Africa used the first version of a CSIR-developed support tool to
assess and compare the costs and benefits of different options for collecting
source-separated recyclables, based on each municipality's unique context.
Separation at source refers to the segregation of solid
waste at the location where it is generated, such as a household or
A second iteration of
the tool that will focus on socio-economic and environmental impacts, thereby
delivering more holistic results that empower municipalities in implementing
waste separation at source, has been developed.
This second iteration
of the model provides for the consideration of the impacts on employment and
livelihoods, landfill airspace savings and increased lifespan, amongst others.
These impacts are monetised to accommodate them within the economic
cost-benefit framework of the model. Thus, municipalities are able to assess the
trade-offs between financial, socio-economic and environmental impacts easily,
using a common metric. This empowers municipalities to make more informed
decisions in identifying the most appropriate option for implementing
separation at source.
suggest that the case for separation at source improves significantly when
socio-economic and environmental impacts are considered.
