Texas Recycling Plant Saves Water with Air-Cooled Air Compressors

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

There are multiple compressed air applications in a waste management facility. This new recycling center uses laser-guided optical sorters to divide waste, with no human involvement on the sorting line. Laser optics determine what type of material each scrap is, then compressed air jets maneuver each piece to its collection area. Compressed air also powers handheld blow guns used for cleaning, as well as the bundling and packaging system.

Brewing a More Sustainable Future at Tröegs

By Brooke Jones, Compressed Air Best Practices® Magazine 

Beer manufacturing creates three byproducts: heat, CO2 and alcohol. The CO2 vents back into the atmosphere, but soon Tröegs will be able to put it into a collection system and reuse it.

Atlas Copco Compressors Enables Sustainability-Based Production

By Mike Grennier, Compressed Air Best Practices® Magazine

The U.S. air compressor market has a compressed air installed base of at least 15 million horsepower. Further, it evaluated various air audits across different customer types, sizes and segments and determined U.S. manufacturers stand to save around 13 billion kilowatt hours (kWh) annually in electricity associated with compressed air. That translates to a savings of $1 billion in energy costs per year, which would remove nine million metric tons of CO2 annually. That equates to more annual energy usage of more than 1 million homes in the United States.

Don’t Assume Compressed Air Demand Reductions Provide Proportional Energy Savings

By Paul Edwards, President, Compressed Air Consultants

The purpose of this article is to show there isn’t always a proportionally linear relationship between what happens with flow reductions on the demand side of a compressed air system - and what happens with the energy consumption in the air compressor room. Optimizing an entire compressed air system requires precise knowledge of the supply side, how compressed air is used in the process itself and how those two relate together.

Tetra Pak Solutions Conserve Water & Energy for Food & Beverage Sector

By Mike Grennier, Compressed Air Best Practices® Magazine

“Our view is always from the perspective of the value chain from the raw materials to the end product,” Wellendorph said. “How do we work with our suppliers who supply us? How do we look at our own manufacturing to avoid waste? Then, how can our equipment minimize the amount of energy or water it uses when processing and packaging customers products? It’s more than just focusing on ourselves.”

Air Compressor-Chiller Combination Saves Glassware Manufacturer $9 Million Monthly

By Aggreko

A large manufacturer of consumer glassware products in the North East sought a solution for injecting cold compressed air into its refractory furnace. Doing so would minimize the internal corrosion thereby extending the life of the furnace lining and their annual maintenance interval. The manufacturer opted for a unique solution from Aggreko Engineering featuring a rental, oil-free rotary screw air compressor combined with a heat exchanger and chiller. Installed in 2019, the solution is expected to save the company \$9 million monthly given the ability to maintain extend furnace maintenance from one year to two years – and boost plant uptime.

TE Connectivity’s Focus on ROI Drives Sustainability Success and Compressed Air Savings

By Mike Grennier, Compressed Air Best Practices® Magazine

The company is succeeding with sustainability at many operations, including its manufacturing plant in Lickdale, Pennsylvania. In fall 2019, officials from the Department of Energy’s Better Plants program joined company officials there to celebrate the plant’s energy achievements – including an 11% reduction in compressed air energy costs. Its ability to reduce the cost of compressed air to the tune of \$223,000 per year is a prime example how many TE Connectivity operations have fully embraced sustainability.

Winpak Reduces Demand by 33% and Switches to Oil-Free Air Compressors

By Ron Marshall, Marshall Compressed Air Consulting

By making changes primarily focused on compressed air uses, Winpak, an international plastics products manufacturer based in Winnipeg, Manitoba, Canada, increased compressed air production capacity and reduced annual energy consumption by 33%. These benefits have been accomplished while the company was making the switch to lubricant-free compressed air to support product quality goals. This article discusses some of these changes and addresses measures that could be implemented in any compressed air system.

Better Plants® Partners Get a Leg up in the Battle for Energy and Water Efficiency

By Mike Grennier, Compressed Air Best Practices® Magazine

In 2019, more than 230 Better Plants partners took advantage of the program to gain considerable ground in their sustainability efforts. In so doing, they cumulatively saved more than \$6.7 billion in energy costs and more than 1.3 quadrillion British Thermal Units (BTUs). These same companies have more than 3,200 facilities and represent approximately 12% of the U.S. manufacturing energy footprint. In addition to energy, partners are excelling at projects to improve water efficiency.
