American city builds roads from recycled dunnies


Recycled toilets have been flushing away the costs of new roads in Colorado Springs for the past eight years, with the porcelain material being reused as an aggregate for road base.

Aggregates from old toilets are being recycled into new roads for Colorado Springs, USA.

Colorado Springs Utilities has repurposed almost 50,000 toilets into road base since 2012.

Porcelain from the toilets is crushed down into aggregate that supplements the gravel that is laid down before the roads are paved.

Colorado Springs Utilities operations supervisor Sean Evans told the material is considered to be one of the best recycled aggregates, compared to recycled concrete and asphalt.

“It’s got great compaction qualities as a recycled product,” Evans said.

Despite an estimated 1.27 million kilograms of toilet porcelain salvaged, it only represented a small amount of the aggregates used by Colorado Springs annually.

Residents are being encouraged to drop off porcelain products, such as sinks and toilets, to the county’s hazardous waste facility.

“We want the community to know they can change out those high use water fixtures and not have to worry,” Evans said. “Bring that toilet to us and we’ll put it back into the infrastructure.”


From quarry to human dung hole

Co-Pilot program keeps up production, safety via touch display


Volvo Construction Equipment has developed Volvo Co-Pilot, an intelligently-designed interactive display that offers real time insight into work performed by select Volvo machines, ensuring the highest standard of efficiency and accuracy in any application.

The high definition touchscreen is the operator’s partner in the cab, providing unrestricted access to all the integrated functionality required to unlock a Volvo machine’s full performance potential. Delivering a range of productivity, fuel efficiency, uptime and safety solutions, the industry-leading 254mm (10”) display gives the operator and owner all of the information they need to ensure a highly productive – and profitable – operation.

Whether digging trenches or loading heavy-duty material, Volvo Co-Pilot offers more control, accuracy and uptime across a variety of applications and machines. However, Volvo Co-Pilot doesn’t work alone. The interactive display works simultaneously with Volvo Assist, which comprises of Dig Assist for excavators, Load Assist for wheel loaders, Haul Assist for articulated haulers and Pave Assist for pavers. Volvo Co-Pilot is designed to work seamlessly with each application, providing real time operational data for a responsive, harmonious and efficient operating experience.

With Volvo Co-Pilot, the operator has easy access to all the unified functionalities of Volvo Assist. With machine, job and material information at their fingertips, operators can do more work per litre of fuel, maximising fuel efficiency and productivity.

In addition to providing precise performance, the heavy-duty display is designed to keep production running – at capacity and to deadline, regardless of the job. Volvo Co-Pilot, and its total synchronisation with Volvo Assist, helps the operator and the machine to achieve greater uptime to keep the job on schedule and the business profitable.

The ergonomically-positioned display reduces operator interaction with fewer on-screen menus, 

helping to keep the focus on the task at hand.


Not only does Volvo Co-Pilot make light work of heavy-duty jobs, it minimises interruptions in the workflow for greater on-site safety. The ergonomically-positioned display reduces operator interaction with fewer on-screen menus, helping to keep the focus on the task at hand. When pre-set operating limits are met, Volvo Co-Pilot alerts the operator through audio and visual signals. Thanks to this intelligent technology, movement around the machine is eliminated as well as the need for additional on-site personnel, improving safety and operator autonomy.

With Volvo Co-Pilot, the operator can quickly and independently manage all operations with ease. The on-board display is intuitive enough to operate with minimal training and provides on-screen tips, optimising ease of operation and uptime. Operators can also customise functions and targets in seconds and easily monitor the progress of their work with greater independence and confidence.

With a 14-gigabyte internal hard drive, Volvo Co-Pilot provides approximately seven months of space to store ample detail of the machine’s performance and productivity. This information enables aggregate producers to analyse machine usage and identify areas for improvement.

When ordering one of the optional Volvo Assist solutions, producers will automatically receive the Volvo Co-Pilot, which is constantly being improved by Volvo engineers. Committed to ongoing and future support, Volvo is developing the Volvo Co-Pilot to provide extended functionalities focused solely on producers’ needs.

It has been more than 25 years since Volvo CE first partnered with CJD Equipment. This successful partnership has supplied Australia’s construction and earthmoving industries with Volvo’s world-class products, along with after-market service and support right across the country.
