Best Practices in Sustainable Paperboard
Procurement
a) Three Focus Areas in Sustainable Paperboard Procurement
1. Long-term Supplier Engagement
Joint Process Improvement
Better Product Understanding
Better Price Negotiation
Cross Country Engagement
Volume Concentration
2. Product Specifcation Improvement
Streamlining the Specications Used
Light Weighting
Reduce or Eliminate Excess Packaging
3. Comply with Environmental Sustainability Measures
Avoid procuring orest products rom countries with highincidences o illegal logging
Perorm lie cycle analysis to understand the environmentalimpact o a given product
Use sustainability scorecards and checklists to ensurecompliance
Seek legal counsel to ensure regulatory compliance
Ensure post-consumer recycled content in paperboardproducts
Reduce energy consumption and switch to renewable energysources

Abstract
This whitepaper ocuses on the current global trends in the sustainable measures in paperboard packaging. It also outlines the dierentmeasures o sustainability and the various steps that have to be taken to ensure sustainable procurement o paperboard packaging.

b) Sustainable Practices in Board Specifcations
Sustainability in Recycled Paperboard
Wastewater measures the amount o process water that is treated
and released to a mill’s receiving waters.
0% recycled paper uses 234,537,650 gallons
50% recycled paper would use 139,755,360 gallons, i.e.
40.41% less.
100% recycled paper would use 44,973,070 gallons, i.e.
80.82% less.
Wastewater volume indicates both the amount o resh water needed
n production and the potential impact o wastewater discharges on
he receiving waters.
Solid Waste includes sludge and other wastes generated during pulp
and paper manuacturing, and used paper disposed o in landlls and
ncinerators.
0% recycled paper uses 22,581,630 pounds.
50% recycled paper would use 18,265,465 pounds, i.e.19.11%
less.
100% recycled paper would use 13,949,300 pounds, i.e.
38.22% less.
Wood use measures the amount o wood required to produce a
given amount o paper.
0% recycled paper uses 40,040 tons, the equivalent o about
280,280 trees
50% recycled paper I would use 20,020 tons less , the
equivalent o about 140,140 ewer trees
100% recycled paper II would use 40,040 tons less, the
equivalent o about 280,280 ewer trees
The number o typical trees assumes a mix o hardwoods and
otwoods 6-8” in diameter and 40’ tall.
An energy credit or energy that is created by burning paper – or themethane that decomposing paper creates – at the end o its lie. The
Net Energy takes the total amount o energy required to make the
paper over its lie cycle, and subtracts this energy credit.
0% recycled paper uses 324,106 million BTUs.
50% recycled paper I would use 263,698 million BTUs, i.e.
18.63% less BTU.
100% recycled paper II would use2 03,290 million BTUs, i.e.
37.27% less BTU.
Greenhouse gases, including carbon dioxide (CO2) rom burning
ossil uels and methane rom paper decomposing in landlls,
contribute to climate change by trapping energy rom the sun in the
earth’s atmosphere. The unit o measure is CO2
equivalents.
0% recycled paper uses 71,374,220 lbs. CO2
e.
50% recycled paper would use 54,353,500 lbs. CO2e, i.e.
23.84% less CO2e
100% recycled paper would use 37,332,780 lbs. CO2e. i.e.
47.69% less CO2e
Sustainable Practices in Board Specifcations
Post-Consumer Waste (PCW): PCW is increasingly being used
in paperboard manuacturing. The post-consumer waste content
recommended by EPA in recycled olding cartonboard in1995
was 35%, and in 2003, it increased to 40-80%. Currently, the
recommendation states that boards can contain PCR content
between 35% and 85%.
Use o Eucalyptus: Eucalyptus is being increasingly used or
paperboard packaging as the availability o eucalyptus is high in
most o the emerging countries o paper and board production.
Usage o eucalyptus satises both the cost and sustainability
parameters. Eucalyptus can be grown cost eectively in low cost
countries, such as Brazil, and it also has a short rotation period.
It also allows achieving greater strength with lower density per
caliper, thereby resulting in higher yield.
Recycled Content: Solid bleached sulate (SBS) paperboard,
with signicantly higher economic and environmental costs,
now has the option o an SBS with recycled content in the inner
layer.
New Technologies: Paper recyclers are developing new
technologies designed to handle, identiy, and separate paper
grades or recycling. One enhancement technology allows
segregation o paper bers during the recycling process
according to ber length, coarseness, and stiness through a
sequential centriuging and screening process.
Aqueous Coatings: Aqueous coatings tend to be the most
environmentally riendly. Most o the ormulations use
nonpolluting water as a solvent.
Soya Inks: Soya ink can reduce carbon emission causing air
pollution making it a more environmentally riendly choice than
traditional inks.
Alcohol-ree Printing: Saety, governmental concerns, and
environmental pressures have caused printers to convert to
alcohol-ree printing. This oers improved quality, lower costs,
a saer pressroom, and improved color reproduction. Alcoholsubstitutes have been developed to replace the alcohol as a
solution making it saer to use.

Conclusion
Sustainable practices in paperboard packaging involve three actors, such as business sustainability, environmental sustainability, andsocial responsibility. Sustainable paperboard packaging practices are increasingly being used due to consumer & retailer pressure,government regulations, environmental concerns, and technological advancements. Long-term supplier engagements, improvement oproduct specication, and environmental considerations have to be taken to ensure successul implementation o sustainability measures.
