An Ammann Asphalt-Mixing Plant helped to create new infrastructure for a sensitive national park in Indonesia while minimising the project’s environmental impact.
Way Kambas National Park in the Lampung province of Indonesia is home to Sumatran tigers, elephants, rhinoceroses and rare birds.
The park also attracts many visitors, who provide the funds needed to preserve the rare wildlife. The roads that support the tourism – which in turn enables the retention of the sensitive habitat – was in need of replacement and expansion.
Way Kambas is one of about 50 ASEAN Heritage Parks worldwide. The goal of such designated parks is to preserve particularly sensitive areas of biodiversity. The park is focused on saving the critically endangered birds and animals that reside there.
Ammann customer PT. Usaha Remaja Mandiri used an Ammann ABA 240 UniBatch Asphalt-Mixing Plant to produce mix for the project.
The ABA UniBatch is the highest capacity plant operating in Indonesia. It is the first plant with a 3.3-tonne mixer. The plant is productive, too, with output of 210 tonnes per hour – essential as the mix had to cover 50 hectares (500,000 m2).
Among the environmental benefits of the plant that were noted by PT. Usaha Remaja Mandiri staff are:
- The plant was equipped with sensors that alerted operators to potential issues early, improving efficiency and safety.
- Only white steam was visible from the chimney. “There was no dust,” an operator said, echoing Widodo’s observation.
- Fuel efficiency was exceptional.
- The mix retained heat for long periods. Only about 5º C was lost during 2 to 3 hours of transport. This heat retention enabled mix to be produced at lower temperatures, reducing fuel burn and emissions.
One of the operators also praised the ease of control. “The plant is very user friendly, and the automatic settings are very accurate,” he said.
“The use of the ABA UniBatch and its baghouse filter enabled the plant to work without dust,” said Hengki Widodo, President Director at PT. Usaha Remaja Mandiri. “The hot-mix product from the ABA UniBatch is cleaner, and the quality is better. The mix even looks different – it looks more shiny.”
