Indonesian cement maker uses waste rubber to generate power

Semen Padang, Indoensian state cement maker, is developing the use of waste materials to replace coal in generating power.

Abusyamsari, a member of Semen Padang’s innovation team, said the cement maker had been using waste rubber since 2011. The company was also developing alternative fuels using sawdust.

“In addition to helping the government in reducing waste, the use of waste rubber can also save production costs,” he told The Jakarta Post.

“With an assumption that we use 100 tons of waste from rubber producers, we can reduce production costs by up to Rp 1.7 billion [US$185,412] per year.”

He added that another benefit was that it was environmentally friendly and reduced CO2 emissions.

“Such environmentally-friendly innovations could save up to Rp 1.3 trillion in production costs in the next five years,” he said.
