Using Outside Air to Keep Data Cool


Caterpillar's main data center has improved greenhouse gas emissions by about 2,500 metric tons of CO2e annually, the equivalent of removing nearly 500 cars from roads. This has been achieved by efficiency improvements to the building's air conditioning system, which runs continuously. Improvements include an automation system that uses more efficient motors for the existing air handlers and equipment that takes advantage of outside air to cool the office during cooler months.

Revamped Scrap Recycling in Piracicaba


A team at Caterpillar Brasil Ltd. (CBL) in Piracicaba, Brazil, has improved its recycling index through a number of improvements to its scrap disposal program. The name of the recycling area has been changed to Byproduct Central to better identify it as an area for materials that can be a source of revenue. The team also has found a new receiver for scrap, consolidated and organized the area where recyclables are stored, and identified additional materials that can be recycled rather than thrown away.

Technical Center Turns Water Use Around


Our Technical Center in Mossville, Ill., has implemented cooling tower efficiency improvements that have resulted in more than 100 million gallons (380,000 cubic meters) of water recycled annually, delivering a 30 percent reduction in process cooling water consumption. Another project focused on process water softener rebuilds and control strategy enhancements saved an additional 35 million gallons (130,000 cubic meters) of water per year. These and other upgrades have resulted in a 58 percent improvement in water consumption over the baseline year of 2008.

Computer Aided Earthmoving for Landfill Efficiency


Caterpillar's Computer Aided Earthmoving System (CAES) enables the re-engineering of landfill site planning and production processes from the machine cab. CAES is available on compactors and track-type tractors for use in landfills. When installed on a compactor, the system indicates to the operator when effective compaction has been achieved. Operators of track-type tractors receive real-time grade and slope information to better utilize cover soil, minimize airspace consumption and work more efficiently with the site plan to reduce costs.

Motor Graders Deliver Efficiency and Performance


The Cat® M series 2 motor graders, equipped with an ACERT™ engine and Cat Clean Emissions Module, deliver the performance and efficiency customers demand, while meeting EU Stage IIIB and Tier 4 Interim emissions standards. Integrated machine systems and technologies improve productivity for greater accuracy, lower fuel use and reduced machine wear. Decreases in fuel consumption result in a decrease of combustion of carbon, reducing greenhouse gases.

CCMC Reduces Greenhouse Gas Emissions


A project team at Caterpillar China Machinery Components (CCMC) in Wuxi, China, set a goal to reduce energy, water and steam use at the plant in order to bring down costs and reduce greenhouse gas emissions. The team's suggestions included upgrading air compressors and switching from metal halide to LED lamps in the plant. These two projects have provided a total reduction of approximately 200 metric tons of CO2e annually.

Investment in Cogeneration in Illinois


Caterpillar's Global Purchasing Division acquired the 51.5 MW cogeneration plant adjoining the Mossville, Ill., Caterpillar campus in 2012. Cogeneration is an energy-efficient means of producing multiple output streams from a single fuel source, in this case, electricity, steam and chilled water from natural gas. For Caterpillar, the plant acquisition:

Proximity Awareness Delivers Mine Safety


Proximity Awareness, part of the Cat® MineStar™ System, delivers a new level of mine safety by providing information to equipment operators and mine administrators about the environment surrounding mobile equipment. Global Navigation Satellite System receivers and data radios on site equipment continually report machine positions to each other and to a central office, allowing every operator to know the real-time position of all other reporting machines.

Safer Fixtures for a Safer Facility


A new process has reduced assembly time and improved safety in Caterpillar's facility in Elkader, Iowa. A project team created a safer and faster positioning process for the production and welding of large u-blade and bracket assemblies. The team decided to place the assemblies in a positioner that would hold them for the welds. An unused turn fixture was recruited, and a saddle was created for the u-blade to sit in when placed in the fixture. A second turn fixture was adapted to hold the bracket assembly.
