North Carolinians dispose approximately 2.3 million tons of packaging waste annually; and nationwide, companies and consumers dispose twice as much packaging today as just three decades ago, from 27 million tons in 1960 to over 60 million tons in 1995. This article explores the dimensions of the packaging issue, including the reasons businesses should be concerned about packaging and steps they can take to reduce the amount of packaging they generate.
Packaging: Facts and Perceptions
Paper and paperboard, the most widely used packaging materials, represent about 40 percent of all packaging used in the country. Next are glass, wood, plastics, and metals, which comprise 19, 16, 14, and 7 percent, respectively, of the packaging used. Most of these materials can be recycled, but recycling is only a partial solution. Research has shown that the major environmental impact of packaging is not in disposal but in the production of the packaging itself. In the long run, packaging systems that use less material and recycle their components will likely provide the greatest environmental and economic benefits.
Consumers Prefer Less Packaging
Compelling reasons to use less packaging come from consumers. According to a 1995 survey by Packaging Digest, more than a third of consumers would like to see simpler packaging of less material, and 19 percent want packaging made from recycled materials. The survey also indicated that "to reduce packaging waste, 7 out of 10 households buy packages that recycle easily, half buy concentrated products in smaller packages, and 3 out of 10 buy products in larger sizes. Twenty percent say they are willing to buy unpackaged products from bulk bins, and nearly 40 percent will reject products that appear to be overpackaged." A 1994 survey conducted by Packaging magazine stated this last finding even more strongly: about one-third of survey respondents said that regardless of other factors, they would "reject products that appear to be overpackaged."
Principles of Packaging Reduction
The four principles arranged below in order of priority have helped many companies achieve substantial cost savings and effective waste reduction. If all four principles cannot be applied, companies should start at the top for the greatest impact/waste reduction.
1. Eliminate unnecessary packaging
If product integrity is not jeopardized, eliminate packaging altogether, or consider eliminating one or more layers of packaging.
Target Stores eliminated about 1.5 million pounds of waste and saved $4.5 million by eliminating unnecessary layers such as individual polybags, tissue paper, cardboard inserts, pins, collar inserts, tape, and clips in its "soft lines" merchandise. All these are now banned from Target's "soft lines" shipments.
2. Reduce packaging materials
Reduce the number and amount of materials used in packaging through the following methods:
- Modify product design; i.e., make products more durable or offer them in bulk or concentrate.
- Decrease the weight of the materials used; decrease the size or volume of the package; and standardize similar boxes to reduce the number of die-cuts.
- Replace multiple materials with single types; for example, replace multiple plastic resins with a single resin.
- Use consumable packages where appropriate; for example, use water-soluble packets for a product mixed in water.
- Replace toxic constituents with non-toxic alternatives, for example, in inks.
- Alter the display packaging; for example, use one large display to hold minimally packaged, single products rather than packaging each item individually.
Several years ago, Home Depot substituted lighter weight slipsheets for wooden pallets in its internal shipping operations and requested vendors to use slipsheets also. The company eliminated 36,000 tons of waste annually and saved $2 million. Its vendors have also benefited from reduced shipping costs as slipsheets cost about one-fifth and weigh 50 pounds less than pallets.
3. Reuse packaging components.
Choose reusable or refillable packaging materials wherever possible. Reuse shipping and transport packaging when distribution distances are short, deliveries are frequent, parties/customers are few, and vehicles are company owned. These features typically occur in closed-loop distribution systems. Ensure that there is adequate indoor storage or protection from weather exposure or other adverse conditions, and consider reusing raw material packaging for shipping.
Alpine Windows worked with its glass supplier to design a system of reusable straps and tarps for shipping window glass. Previously, the glass was shipped in wood crates. With the new system which attaches to trucks specially outfitted, Alpine has eliminated 4,500 crates annually and saved $250,000.
4. Use recyclable packaging.
In packaging design, consider basic issues of recyclability. For example, make packaging components easy to separate for recycling, and do not unnecessarily combine or bind distinct materials. In addition, purchase the highest levels possible of post-consumer, recycled-content packaging materials. This choice helps sustain the markets for these recycled materials and, ultimately, lowers the price of recycled-content products.
McDonald's Corporation has directed its nearly 600 suppliers to use corrugated boxes that contain at least 35 percent recycled materials and include high levels of post-consumer content; the restaurant chain's carry-out bags contain over 50-percent post-consumer content.

By Doug Smith, Packaging Engineer, IBM Corporation, Research Triangle Park, NC
IBM Corporation develops and manufactures networking and personal computer products. Since 1989, IBM has significantly reduced its solid waste stream, largely through packaging redesign.
Packaging design is a good starting point for facilities that are committed to developing proactive environmental design processes. By concentrating on efficient use of minimum amounts of the right materials, a company can optimize packaging design. Once the design is fine tuned, reuse and recycling features can then be incorporated into the package.
But environmental packaging doesn't end with packaging engineers; it incorporates ideas from employees involved in the manufacturing process as well. Once manufactured cartons and cushion assemblies are moving through the production lines, many environmental improvement opportunities can still be identified. Here are a few basic guidelines that helped IBM reduce its waste stream and cut costs:
- Organize a team to promote communication across manufacturing areas. IBM formed a green team - a team of environmentally minded volunteers from each manufacturing area - to identify reuse and recycling opportunities in each area. The team held periodic meetings to discuss these opportunities and to evaluate their environmental, economic, and practical worth.
- Set up clear communication between packaging and manufacturing. Packaging designers need to be aware of product and package assembly problems. For this reason, manufacturing teams frequently discussed their ideas and concerns, such as assembly difficulties or bottlenecks, with the packaging engineers. Such exchanges resulted in packaging upgrades that reduced material usage and increased productivity.
- The best lever for reducing packaging is a rugged product. The better built and more rugged the product, the less protection or packaging material needed. By creating an environment in which assembly workers take pride in the assembly process, IBM ensures well built, durable products that can survive with reduced packaging.
- Conduct periodic inspections of the packaging on raw materials. Since packaging engineers primarily design finished packaging, workers who use raw materials should look for ways to eliminate or reduce packaging on those materials, especially on nonfragile parts. Always check with your local packaging expert before working with a supplier to change an incoming pack design.
- Look for reuse and recycling opportunities. Consider reusing materials either internally or externally; and if reuse is not an option, identify and collect recyclable materials that are generated in high volumes. IBM reuses pallets, diskettes, cardboard boxes, electrostatic discharge boxes, and other products and has company-wide programs to recycle cardboard, metal, paper, polystyrene, glass, and other materials.
Once these guidelines are incorporated into manufacturing, the results will speak for themselves: solid waste generation and disposal costs will decrease. As an added bonus, customers will have less material to dispose, and much of it can be readily recycled. To accomplish these results, packaging design must be attacked with creativity, innovation, and a cohesive team representing diverse areas of the facility.

Corning, Inc.'s Telecommunications Products Division, in partnership with Re-Source America, Inc. (Re-Source), has developed a patented system to recover all packaging material used in the transport and distribution of Corning Optical Fiber from the Wilmington, NC, facility.
The company designed a reusable package that met the same quality requirements as new packaging material. Corning redesigned its shipping spool and added a plastic spool cover to give added protection to the fiber and the spool during shipping. The spool is then shipped in a reusable plastic container.
As each container leaves the facility, a prepaid return address label is applied, which also provides information on the return system. Customers send all Corning packaging material to Re-Source in Southampton, PA, for quality inspection. Re-Source cleans all spools and covers and inspects and returns qualified material to Corning. Material deemed not reusable is recycled.
Corning has a customer return rate of over 95 percent and a similar reuse rate. The company estimates that it has eliminated over one million tons of packaging waste with this system.

- Stretch wrap on pallets with rubber bands?
Traex, a company that makes plastic injection molded products for the food service industry, replaced stretch wrap with reusable rubber bands on pallets used internally. This change eliminated over 1.3 million square feet of stretch wrap, saved over $50,000 in just one year, and achieved payback on the rubber bands in four shifts.
- Corrugated boxes with plastic straps?
Cereal giant General Mills redesigned its packaging to reduce the amount of corrugated by 30 percent, or approximately 3 million pounds per year. Instead of being packaged in corrugated boxes, cereal boxes are now held tightly between two corrugated sheets by plastic straps.
- Wood pallets with reusable pallets?
After working with its supplier to identify and test possible pallet replacements, Pepsi-Cola Bottling of Phoenix replaced wood pallets with reusable plastic pallets. The results: raw material losses have fallen dramatically, labor to repair pallets has been reduced, and wood waste has been reduced by over 50 percent.
- Polystyrene peanuts with starch peanuts?
The Museum of Modern Art in New York City switched to cornstarch-based peanuts to protect the exclusive gifts it ships around the country and the world. As these peanuts are water-soluble, they can be dissolved in water or added to the compost pile. Unlike polystyrene, the starch peanuts are made from renewable resources and do not exhibit static cling.

Solid Waste News
IDP Grant Awarded
With a grant funded by EPA Region IV, the NC Division of Pollution Prevention and Environmental Assistance is pursuing industrial solid waste reduction through an Industrial Discards Project (IDP). For North Carolina to reach its 40-percent solid waste reduction goal by 2001, it is essential that this waste stream is targeted.
The IDP will work with 50 industries within 10 industrial-based, medium-population counties to identify solid waste materials and costs and to assist with marketing solid waste materials. Two workshops will be conducted on industrial solid waste reduction, and a database of supply-side solid waste will be created to help match generators with recycling markets or users of raw material feedstock. It is estimated that over 15,000 tons of solid waste will be diverted from the waste stream over the 18-month project.
For more information, call Scott Mouw 919-715-6512 or 800-763-0136.
Water Quality News
Reducing/Removing Color in Effluent
Although the North Carolina Department of Environment and Natural Resources does not have a statewide or basin-wide effluent color limit for National Pollutant Discharge System permit holders, a number of companies and municipalities in North Carolina are subject to compliance with locally established or voluntarily imposed color limits. Local limits have typically been established as a result of citizen complaints.
To increase knowledge about existing color reduction/removal technologies, the North Carolina Division of Pollution Prevention and Environmental Assistance (DPPEA) is working with companies and municipalities that are currently reducing or removing color in their effluent. The DPPEA intends to promote the activities of these facilities by developing a publication of individual case studies that will discuss the type of industry, the type of effluent being treated, the reasons for implementing the color reduction/removal technology, any source reduction techniques used to reduce color in the effluent, a description of the technology itself, and the economics of purchasing and operating the color reduction/removal technology.
DPPEA intends to compile these case studies by the end of 1997 and, in association with the Division of Water Quality, conduct a color reduction/removal seminar in which these companies and others discuss existing and new techniques for reducing color in the effluent. Any facility that is significantly reducing color in its effluent through source reduction and/or non-conventional treatment techniques and is interested in participating in the case study development should call John Burke at 910-249-1480.
Air Quality News
EPA Adopts New Ambient Air Quality Standards
On July 16, 1997, EPA adopted new ambient air quality standards for ozone and fine particulate matter. The Division of Air Quality (DAQ) has determined that according to 1994-96 data analyses, monitors in 13 North Carolina counties would violate the new ozone standard. The DAQ is currently not certain which areas will be affected by the new fine particulate standard because the Division has not monitored for the fine particulates in the past. However, all counties in the state have been in compliance with the existing ozone standard since 1990, and no areas in North Carolina have ever been designated nonattainment under the former particulate standards.
The EPA plans to determine ozone attainment in the year 2000 using monitoring data from 1997 through 1999. Control strategies in the form of State Implementation Plans for areas in violation would be due from the State in 2003, with the implementation measures in place by 2005. The EPA does not plan to designate areas in violation of the new particulate standard until 2002 or later.
Facilities that are considering additional air pollution control devices should first assess the source of pollutants and then determine potential methods for reducing the associated releases through pollution prevention. For specific information on cost-cutting pollution prevention techniques for air pollution reductions, call the NC Division of Pollution Prevention and Environmental Assistance at 919-715-6500.

DENR Enters Second Year of Partnership with EPA
In May 1995, the Environmental Council of States and the U.S. Environmental Protection Agency (EPA) initiated the National Environmental Performance Partnership System (NEPPS). In short, NEPPS is a set of principles mutually agreed between States and EPA to enhance environmental protection nationwide. Some of the advantages of NEPPS include increased recognition of state environmental priorities; reduced EPA oversight for strong state programs; stronger bases for combining or shifting federal funds across media; improved measures to track and communicate environmental results; elimination of duplicative realtime project reviews; and measures to reduce reporting of activities.
The actual agreement that documents State and EPA understanding of NEPPS implementation is a Performance Partnership Agreement (PPA). The 1997 PPA is the second negotiated Agreement for the Department of Environment and Natural Resources (DENR). DENR's first PPA in 1996 was developed with three regulatory programs (air, water, and hazardous waste) and one non-regulatory program (pollution prevention). This year's PPA includes the state's groundwater program.
DENR realizes that North Carolina citizens have a real interest in the way environmental protection is implemented and the results measured. This year, we will be looking for ways to have meaningful public participation on implementation and to provide meaningful reports of results. For more information on this topic, contact Jimmy Carter, Chief, Hazardous Waste Section, PO Box 29603, Raleigh, NC 27611.

On August 19, 1997, eight North Carolina facilities were presented the Governor's Award for Excellence in Waste Reduction. This awards program continues to recognize North Carolina facilities for their outstanding commitment to protecting the environment and public health through waste reduction and sound management strategies. Below are summaries of the Outstanding and Significant Achievement Award winners.
Outstanding Achievement for Large Business
R.J. Reynolds Tobacco Company, Winston-Salem, was recognized for recycling, hazardous waste recovery, nonhazardous parts washing, ash reuse, and waste-to-energy waste reduction programs. Waste reduction activities include an enclosed automated washing system that uses a nonhazardous solvent; solvent recovery; diversion of ash from cogeneration plants; pelletization of nonrecyclable waste paper for use as a fuel supplement; and an extensive recycling program. RJR waste reductions in 1996 included 300,000 gallons of solvent recycled and another 650,000 gallons recovered for reuse or sale. The company has realized approximately $950,000 in annual cost savings and $2.7 million in annual revenues.
Thomson Crown Wood Products (TCWP), Mocksville, manufactures wood and wood-finished cabinets and storage units for audio and video equipment. TCWP's waste reduction initiatives involved substitution of a toluene glaze, implementation of a standardized set-up procedure with checklists and log books in the Banding Department, and grinding of wood waste for burning in the cogeneration facility. The company's grinding program diverted 4,689,000 pounds of wood waste from the Davie County landfill in 1996. Annual savings amount to over $850,000.
Outstanding Achievement for Small Business
The Ocracoke Island Hammock Company (OIHC), Ocracoke Island, manufactures hammocks and confectioneries. To reduce the large quantities of packaging materials generated primarily by its mail order program, OIHC implemented a cardboard reuse program. Incoming boxes are broken down and stored while other packaging materials such as Styrofoam peanuts, and shredded paper are stored in 50-gallon receptacles. The shipping department then uses these materials to package the outgoing product. The company encloses a note to customers explaining the unusual mixture of packaging materials. Since all solid waste generated on Ocracoke Island must be ferried to the mainland, the company's reuse program helps to reduce the island's uniquely expensive disposal costs.
Outstanding Achievement for Federal Facility
The Second Marine Aircraft Wing, Cherry Point, operates and maintains 151 aircraft and over 1,000 pieces of mobile equipment. In response to increasing costs, environmental concerns, and Federal Executive Order 12856, MCAS implemented the following waste reduction activities: a Hazardous Materials Control Center, an extensive recycling program including a mandatory curbside household recycling program, and use of nonhazardous solvents in all parts washers. Annual savings are approximately $4.6 million through revenues and avoided costs.
Significant Achievement for Large Business
Springs Industries, Inc., Aileen, produces wide sheeting for sheets, comforters, and other accessory lines. Waste reduction activities included implementation of reusable totes and reusable plastic pallets, employee team suggestions for process waste reduction, sizing agent reuse, and an extensive recycling program. Between 1990 and 1996, Springs reduced the amount of solid waste landfilled by 90 percent and achieved annual savings of more than $200,000.
Zimmer Patient Care Division, Statesville, produces over 2000 orthopedic and surgical products at its Statesville facility. An interdepartmental life cycle analysis of packaging materials that eliminated 4.5 million linear feet of polyolefin film and 175,000 cubic feet of polystyrene peanuts from shipping containers saved the company over $230,000. By diverting 30,000 pounds of foam offcuts to a local carpet manufacturer, the company reduces landfill costs and generates over $7,500 in income annually.
Significant Achievement for Small Business
Furst-McNess Company, Statesville, manufactures vitamin and mineral premixes for livestock feeds. Instead of landfilling excess materials at the end of a production run, the company now stores these materials and recycles them back into the same product the next time it is manufactured or provides them free of charge to the customer. With over 20,000 pounds of material reused annually, Furst-McNess realizes savings of over $8,000 as well as improved customer relations.
Significant Achievement for Government Facility
In 1993, Coastal Carolina Community College (CCCC), Jacksonville, became one of a few institutions nationally and the first in North Carolina to recycle polystyrene. The college collects the polystyrene from eating areas, and the recycling vendor supplies the baler for the material. Also, by purchasing outdoor furniture made from its recycled plastic material, the college effectively "closes the recycling loop." CCCC's more than 22 recycling programs, which divert over 70 percent (60 tons) of its solid waste stream from the landfill, have saved the college over $150,000 since 1993.
Case Studies: Achievements in Waste Reduction
The following entrants were selected as facility case studies in the 1996 awards program in special recognition of their significant contributions to North Carolina's waste reduction efforts: North Carolina Correction Enterprises - Paint Plant, Smithfield; Moen, Inc., Sanford; Outboard Marine Corp., Andrews; and Tin Originals, Inc., Fayetteville.
