FLSmidth system to be installed in New Zealand

As authorities struggle to find effective disposal solutions, the piling up of car tyres is becoming a growing problem for many countries. By burning tyres and other solid materials, heating and power plants can help to solve this problem, creating energy for use in households and industry – including cement production.

With New Zealand currently throwing away more than 5 million tyres every year, Hon Eugenie Sage, New Zealand’s Associate Minister for the Environment, has recently signalled that the government’s priority work programme for waste will include a greater focus on product stewardship for end-of-life vehicle tyres.

The cement industry is well-positioned to make an impact. Around the world, many cement producers have been successfully replacing fossil fuels with alternative solid fuels (including vehicle tyres) as an energy source. This has the effect of both minimising energy costs and reducing a plant’s carbon footprint.

Reducing environmental footprint

One of New Zealand’s largest companies, Fletcher Building, is participating in the programme. The company will install a FLSmidth HOTDISC® Combustion Device at its Golden Bay Cement plant in Portland, North New Zealand.

It has been reported by local media that substituting rubber biofuels for coal will reduce CO2 emissions by 13 000 tpy, or the equivalent of emissions from 6000 cars. Once fully operational, the system will enable the kiln to consume up to 3.1 million shredded tyres each year. This will replace the need for more than 15 000 tpy of coal.

Cement production process boost

The installation of the system at Golden Bay Cement points to growing demand. It has been noted that the system is experiencing a boom in many parts of the world, but especially in China.

“Whereas we previously experienced market demand of one of two units a year, we are now projecting the sale of 10 units in 2019,” said Carsten Damslund Jensen, Global Product Line Manager at FLSmidth. “It is not only a good business case for cement producers and other energy hungry industries, but also good news for the environment.”
