Flexible Packaging – Lightweight. Less Waste. Less Energy Consumption.
As a whole, the technology and innovations of the flexible packaging industry have led to package minimization, waste reduction, and reduced energy consumption.
Glenroy considers environmental awareness and conservation a priority. 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, quite simply, a better living and working environment for everyone.
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.
Air 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.
- 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.
- We have reduced manufacturing process waste by 40%.
- Of our recycled press wash solvent, 80% is processed into reusable fuel.
- We recycle 70% of the solvents used in our printing processes.
- We Recycle
- between 40 and 50 tons of packaging trim scrap every two weeks.
- approximately two tons of paper every two months.
- approximately six 55-gallon drums of aluminum cans, plastic bottles, and glass containers every six weeks.
- approximately 300,000 pounds of wood pallets, sideboard, and packaging every year.
Through our recycling programs, more than 3 million pounds of materials are kept out of landfills and kept in the materials cycle every year.
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, and contributes less to landfill waste (even when including recycling rates of other packaging formats).
According to a life-cycle assessment study (LCA) by the Natural Marketing Institute (NMI), inverted pouches greatly reduce environmental impact when compared to glass bottles. The results of this assessment show that STANDCAP inverted pouches:
- Reduce fossil fuel usage by 65%
- Reduce greenhouse emissions by 77.8%
- Reduce overall water usage by 80.6%
*Pouches also eliminate the need for a separate label or shrink sleeve.
- This convenient, lightweight 24-oz pouch weighs 20 g (sprayer not included) as opposed to 51 g for a typical 24-oz plastic bottle.
- One truckload of pouches holds 364,000 packages while the same quantity of like-sized rigid bottles would require nine truckloads.
- The additional eight truckloads traveling 1,000 miles will require an additional 2,000 gal of fuel and emit nine times the amount of greenhouse gases.
Unlike typical plastic bottles, which can waste about 14% of ultrasound gel left on the bottom, this lightweight flexible package design requires less energy to manufacture & transport and allows for up to 99.5% evacuation of the product, reducing the number of units consumed each year.
As a result, 1.5 million fewer containers and 800,000 less pounds of gel will end up in landfills. This reduced waste contributes to a yearly savings of $1.9 million for the industry.

Flexible Packaging Association
The Flexible Packaging Association (FPA) has served as the voice of the flexible packaging industry since 1950. The FPA is currently leading an industry effort to better understand all aspects of packaging sustainability, end-of-packaging-life programs, and resource recovery alternatives.
Sustainable Packaging Coalition
The Sustainable Packaging Coalition (SPC) is a membership-based collaborative that believes in the power of industry to make packaging more sustainable. The SPC is the leading voice on sustainable packaging and is passionate about creating packaging that is good for people and the environment.
