The use of single-use plastics in households has become a pariah. Many people are trying to reduce the use of single-use plastics or to recycle them.

Schalk Mouton asks Professor Herman Potgieter, the Head of the School of Chemical and Metallurgical Engineering, if ecobricks are really a good idea.
