Customer Sustainability

Sustainable Solutions for Every Environment

In the ocean, on the road and inside mine sites, Caterpillar teams are responding to customer needs for increased efficiency and decreased GHG emissions. Recent technological innovations are helping our customers become more sustainable in unexpected ways.

Enabling the Green Ship

Electric power plants with multiple engines on board sea-going vessels are not typically integrated, leading to unnecessary expense and fuel use. The new Marine Multi-Engine Optimizer (MEO) software determines not only what is the best quantity of engines to run, but also the optimal combinations of load factors for running engines. The system provides up to 20 percent fuel savings and up to 50 percent NOx reduction, depending on load variation, and allows Caterpillar to set the industry standard for vessel optimization. While MEO was designed for marine applications, it may be adapted for electric power and even drilling operations.

Shifting the Future of Hauling Transmissions

The Energy Technology Institute (ETI) is instrumental to the UK’s carbon reduction efforts. When ETI partnered with Caterpillar to develop heavy-duty machines with a lower carbon footprint, the result was more impressive than they could have expected. Within 24 months, the team became the first to successfully demonstrate a hydro mechanical continuously variable transmission (CVT) in a hauling product. The technology offers fuel savings and will be leveraged across other Caterpillar machines.

A Clean Air Solution for Australia’s Olympic Dam

When the Olympic Dam Mine in Australia wanted its diesel powered underground fleet to meet Tier 4 final emission standards, CavPower, a Cat® dealer for South Australia, approached the Hard Rock Vehicles product group for help. Space is extremely tight on underground machines. It was one thing to come up with a solution that met the customer’s need to reduce emissions and quite another to fit the solution into the machines. To solve for both, the team developed an electronically monitored, fully integrated hyper-efficient diesel particulate filter system. The system reduces emissions below Tier 4 final requirements without the need to replace all equipment. Now, the miners at Olympic Dam are breathing cleaner air, and their employer is working smarter, more profitably and mining more sustainably by using Cat equipment.

Circular Resource Use Hits the Road

There are more than 2.6 million miles of paved roads in the United States according to the American Road & Transportation Builders Association, and more than 94 percent of them are surfaced in asphalt. So its no wonder that asphalt is a major industry, employing directly or indirectly 300,000 workers at 4,000 mixing plants at the National Asphalt Pavement Association’s (NAPA’s) last count. Asphalt pavement is also the most recycled material in the country according to NAPA, and acceptance of its recycling and reuse is growing. Asphalt mixes that include recycled materials, such as reclaimed asphalt pavement (RAP), offer equal or better quality than pavements with virgin materials and make more efficient use of resources. With significant investment in our cold planer and rotary mixer product lines, Cat Paving is providing expanded offerings and solutions that allow customers to engage in sustainable infrastructure development.

The Next Generation has arrived

In 2017, Caterpillar announced three Next Generation 20-ton size class excavators –the 320 GC, 320 and 323. These excavators increase operating efficiency, lower fuel and maintenance costs, and improve operator comfort compared to previous models. The new excavators offer unique combinations of purpose-built features designed to match customers’ productivity and cost targets.
