Eurotec concrete batching plant sets the standard for dust free operation in Malaysia

Kuala Lumpur, Malaysia, saw a Eurotec MZP200 ready mix concrete batching plant installed within an enclosed warehouse in the Chan Sow Lin district as part of a sustainability drive in 2014. It was a design idea that proved so successful, other companies in the country adopted the design, leading to significant improvements in local air quality.

“Seven years ago, this was the only plant in Malaysia with the enclosed design, but it quickly caught the attention of the local construction industry who were all impressed with the reductions in noise and dust emission levels it delivered,” said R. Sakthi, CEO at Lintec & Linnhoff Concrete Pte Ltd. “This greatly improved air quality and helped the Malaysian industry take another step towards more sustainable infrastructure development.”

Similar to the other readymix concrete plants in the MZ series, the Eurotec MZP200 features a modularised structure for easy and quick installation and maintenance. The project in Chan Sow Lin was completed inside an almost totally enclosed warehouse, with the plant’s six aggregate bins, multiple tall cement silos, centre-discharge conveying system and static aggregate ground-feeding conveying system all assembled within the giant structure. This way dust and cement are contained within the compound, rather than polluting the external environment and nearby residential areas.

Production volume up; audible volume down

The cement batch plants worked for 10 hours per day, producing up to 4.5m3 per batch or up to 200 m3/hour of readymix concrete for construction and infrastructure projects in Kuala Lumpur and the Klang Valley. Despite this, the Eurotec MZP200 concrete batch plant was notable for the reduced noise and dust.

By March 2015, the plant achieved another milestone when it was awarded SIRIM QAS International Sdn Bhd’s ISO 14001:2004 certification in the Manufacturing of Ready Mix Concrete category.

“Our engineering detail allows the MZ batching plant model to fully reclaim returned concrete by separating the sand, aggregates and water, and then recycle them back into the batching process,” said R. Sakthi.

The combination of an enclosed warehouse for the concrete plant, plus an operational capacity to fully reclaim returned concrete is a perfect design for urban locations. Increasingly in Asia there is greater attention being paid to delivering better air quality, with the Asian Development Bank even launching a Clean Air for Livable Cities series to support the initiative. At the same time, demand for greener construction continues to rise, and interestingly this is being supported by end users, with recent research showing that most Asia-Pacific companies would pay higher rent to lease a building with stronger green credentials.

As this trend continues, contractors will increasingly look for innovative designs and advanced technology in their mission of producing good quality concrete that can help them deliver more sustainability-certified buildings.

Customisable design to suit local needs

With an extensive range of customisation options to suit the requirements of any major project, the Eurotec MZ series can be designed with one mixer and two discharge chutes to reduce the waiting time of mixer trucks, thereby increasing productivity and reducing fuel use. The energy consumption – along with wear and maintenance costs – of the batch plant is also reduced via the use of computer-controlled twin-shaft mixers that ensure high accuracy. Operating at high torque, their three-dimensional mixing motions generate a higher consistency of concrete.

“This project showed that it is entirely possible for concrete batching plants and local residents to co-exist peacefully, as long as proper attention in detail is paid to the environmental impact,” concluded R. Sakthi. “Now the enclosed Ready Mix Concrete plant has become popular and other jobsites have started adopting it to reduce pollution. This is one early design inn
