Researcher Finds New Ways To Combat Global Warming


A KwaZulu-Natal researcher believes recycling human hair is one way to combat global warming.

Ntwanano Malepfane has found human hair can be used as a fertiliser.

She’s a Soil Science Masters student at the University of KwaZulu-Natal.

Malepfane has sampled hair from three ethnic groups — African, Indian and Caucasians.

She analysed them for traces of heavy metals as well as nitrogen, sulphur, phosphorus and potassium.

The 24-year-old then incubated the hair for about a month.

The results indicate that the hair released enough nitrogen to grow spinach.

But Malepfane also says human hair can sometimes be toxic to the environment if it’s not thrown away correctly.
