GW 10 – Commercial and Industrial waste

Commercial and Industrial waste is also not defined by the Waste Act, 2008. The composition of commercial and industrial waste is related to the type and scale of industries prevalent in a specific region. A large portion of this waste stream is collected as part of the municipal waste stream and contains mainly mainline recyclables from offices and organic waste. It should however be noted, that pre-consumer recyclables from industrial sources are not collected as part of the municipal waste stream.

The best sources of information on commercial waste are municipal service providers and the relevant industry associations for industrial waste. It should however be noted that not all industries are affiliated to industry associations. Therefore, data obtainable from industry associations are limited to their membership.
Data on general waste from commercial and industrial sources was obtained from the Chemical and Allied Industries Association (CAIA), some IWMPs and national government reports. The data was however not sufficient to allow accurate estimates. Therefore, this waste stream is reported as a portion of the municipal waste based on the assumptions as explained in section 2.2 of the main report.
It may be worth investigating whether commercial and industrial waste data can be related to GDP, in a manner that is consistent with historical data. One example could be to use an elasticity approach in the following manner:
Extrapolated waste = (initial waste)*(expected GDP)^(elasticity)
This type of approach would require historical waste and GDP data, in order to estimate the elasticity (using regression). In addition, it would require a projection of future GDP values (possibly from National Treasury) in order to obtain extrapolated waste data. Naturally, this approach operates under the assumption that the elasticity remains unchanged over the period of extrapolation. Otherwise stated, this method assumes that the overall mechanism which produces the waste remains the same (i.e. there are no structural changes).
