Holcim Indonesia: Co-processing cut tires, a first in Southeast Asia

Geocycle Indonesia is the first Holcim operation in Southeast Asia to obtain the necessary permits to import cut waste tires. With their high calorific value, the tires provide an excellent source of alternate energy for Holcim Indonesia cement kilns, and reduce the reliance on fossil fuels.

Holcim Indonesia's Clean Development Mechanism target is to reduce CO2 emissions. The use of alternate fuel contributes towards this, in particular the use of energy rich alternates such as cut tires, which contain one and half times the calorific value of coal.

The process of obtaining the required permits from the Indonesian Ministry of Environment began in 2007; with permits for a trial burn being received in mid 2008.
In April 2008, Geocycle received 1,500 tonnes of tires in 71 containers from Reunion, a tiny French dependency in the Indian Ocean, 5,769 km from Indonesia. Upon receipt, the tires were analysed with x-ray technology to determine sulphur levels and calorific content.
During the first trial burn, the imported waste tires were manually-loaded and co-processed at a rate of 1.5 tonnes an hour over 10 hours. The progress and results of this and the subsequent trials were monitored and assessed until an optimum co-processing rate was achieved.

The Reunion consignment, with its high calorific value, makes an ideal alternative fuel.

Geocycle Indonesia is a business unit and integral part of Holcim Indonesia, focusing on providing waste management solutions for customers. Energy and mineral components in waste are recovered by co-processing it in our cement kilns. Co-processing waste is an environmental friendly solution to waste problems.
