Green Initiatives

For decades, Glenroy has been dedicated to preserving the environment through air emissions control, energy conservation, and recycling initiatives. Good stewardship of resources has been a principle of Glenroy, Inc. since our company was founded in 1965.

Our culture promotes continuous improvement, and environmental awareness is one of the areas where we have made great strides.

LeavesAir Emissions Control

  • We have significantly reduced our VOC emissions by switching our flexographic printing from an open-air decking system to a closed central-impression system. This prevents VOC’s from escaping into the ambient environment.
  • Since 1989, we have destroyed over 98% of captured VOC emissions through the use of catalytic and regenerative thermal oxidizers. Our regenerative thermal oxidizers utilize high-efficiency heat exchangers to thermally destroy HAP’s and VOC’s.

Light BulbEnergy Conservation

  • By installing energy efficient lighting in our manufacturing facilities, we have reduced energy consumption of lighting by 26%.
  • Our electricity consumption has been significantly reduced in winter months through the utilization of a free cooling loop on our process chilled water system.

RecycleRecycling Initiatives

  • We have reduced manufacturing process waste by 40%.
  • Of our recycled press wash solvent, 70% is processed into reusable fuel.
  • We recycle 70% of the solvents used in our printing processes.
  • We Recycle
    • between 20 and 22 tons of packaging trim scrap every two weeks.
    • approximately one ton of paper every two months.
    • approximately four 55-gallon drums of aluminum cans, plastic bottles, and glass containers every six weeks.
    • approximately 250,000 pounds of wood pallets, sideboard, and packaging every year.

Through our recycling programs, more than 100,000 pounds of materials are kept out of landfills and kept in the materials cycle every month.

FibreForm® – The New Sustainable Alternative to Rigid Plastics

Glenroy and BillerudKorsnäs have teamed up to bring you FibreForm®-an innovative new packaging material that is changing the shape of the packaging industry. FibreForm® is an all-natural FSC-certified paper with proprietary forming capabilities and extremely high stretch characteristics. This revolutionary packaging material allows your packages to feature sculpted effects previously unattainable with paper packaging, including deep, tactile embossing and unique thermoformed shapes.

FibreForm is available with biodegradable coatings such as polylactic acid (a renewable material derived from corn), or with various other coatings to provide desired barrier and/or sealing properties.

Flexible Packaging – Less Waste in the First Place

As a whole, the technology and innovations of the flexible packaging industry have led to package minimization, waste reduction, and reduced energy consumption.

When compared to other packaging formats, flexible packaging generally:

  • weighs less – resulting in less waste.
  • has a better product-to-package ratio.
  • consumes less energy in manufacturing and transport
  • generates less greenhouse gas emissions.
  • contributes less to landfill waste (even when including recycling rates of other packaging formats).

The flexible packaging industry continues to devote resources to developing products that are sustainable and safe for the environment.

Our organization has a dedicated team of professionals committed to looking for new ways to reduce our impact on the environment. Through our efforts, the employees of our companies and the communities in which we operate benefit through reductions in energy use, preservation of air quality, landfill waste reduction, and a better living and working environment.
