Congress of the People MP Tshilidzi Ravhuanzwo said the party was made aware about a week ago that "piles and piles" of books were being dumped.

The books and stationery, some still in their original packaging, were being burnt and shredded.

"So many schools don't have books, and [even old books] could have been used in libraries," she said.

Ravhuanzwo said that books from the previous curriculum would still be useful to teachers and pupils because the learning content did not change.

"We really need those old books, I would have like to have stopped them [destroying the books].

Limpopo education department spokesman Pat Kgomo said the matter only came to the department's attention on Friday.

How the materials came to be dumped was under investigation, he said.

On Friday, Basic Education Minister Angie Motshekga denied blame for a delay in the delivery of textbooks to the province's schools.

"I have not considered resigning," she told reporters in Polokwane.

"The best I can do is sort out what I started. I won't jump ship."

She blamed the delay on factors including cash flow and administrative problems.

In May, the High Court in Pretoria ruled the department's failure to provide textbooks violated the Constitution. The application was brought by rights organisation Section 27.

Motshekga said her department had met with Section 27 and agreed to move the deadline to Wednesday.
