Green Choice 100 Paperboard


Strathcona Paper LP, a division of CanamPac, is a Canadian manufacturer of 100% recycled clay coated boxboard, and launched GreenChoice 100 in June 2007. In addition to having Eco Choice certification, which all of Strathcona Paper's products have, GreenChoice 100 is made from 100% recycled fibres, is also 100% recyclable and is the first and only recycled paperboard that is 100% carbon neutral with 100% of the energy used in its manufacture offset with clean renewable energy. Strathcona Paper, as recycled paperboard manufacturing specialists, has always felt it important to exceed standards whether in its manufacturing and supply chain processes or in its products and it was with this philosophy that the idea of GreenChoice 100 was conceived.

Motivation for Change

Strathcona Paper LP is committed to conducting its business and operations in an environmentally sensitive and responsible manner and regularly reviews its environmental objectives and targets that are consistent with this Environmental Policy and Strathcona’s Environmental Management System. Strathcona Paper set out to manufacture the most environmentally sustainable packaging substrate in North America today.

Cost Effectiveness

As a 100% recycled folding carton packaging substrate, GreenChoice is competitively priced compared to other recycled paperboard substrates. In addition, GreenChoice 100’s printability is second to none with higher brightness and plybond than industry averages providing strong graphic reproduction, which together with its strength properties allow converters to enjoy increased press efficiencies and brand owners improved filling line speeds. Strathcona Paper’s Quality Management System is registered under the ISO-9001:2000 standard. Stringent Quality Management Systems ensure GreenChoice 100 has fewer product defects thereby providing enhanced productivity and faster turnaround.


GreenChoice 100 paperboard has a 3:1 MD:CD ratio (one of the highest in the industry).This superior stiffness permits folding cartons manufactured by converters using GreenChoice 100 to reduce caliper and therefore “right size” packaging. Agreement by the FDA (US Food and Drug Administration) and CFIA (Canadian Food Inspection Agency) for direct food contact also reduce the need for double packaging. GreenChoice 100’s superior stiffness and block compression strength permits it to be used as a packaging substrate for a folding carton as a substitute to litho laminate micro flute packaging applications, reducing the manufacturing process and energy consumption applicable to producing the package for the same goods.


Strathcona Paper’s GreenChoice 100 is manufactured from 100% post-use recycled waste paper fibres. Approximately 65% of this post-use waste is post-consumer material and 35% is industrial scrap. The top-liner consists of pulp substitute fibres such as computer printout and sorted office waste paper with a recycled filler comprised of double lined kraft, old corrugated containers, boxboard and old newspapers. GreenChoice 100 can be produced with an application of special biodegradable sizing agent to provide moisture resistance to the paperboard.

Clean Production

GreenChoice 100 is manufactured by Strathcona Paper LP, the only 100% recycled clay coated boxboard mill in North America to have its Environmental Management System registered to the rigorous global standards of ISO 14001, having achieved this status since 2001. ISO annual audits and the Environmental Management System ensure that Strathcona’s production processes are continually being evaluated and improved from an environmental performance perspective. In 2007 Strathcona Paper received Environment Canada’s Environmental Choice Certification, the only North American recycled paperboard mill to achieve this standard.

Effective Recovery

GreenChoice 100 is 100% recycled, recyclable and carbon neutral and is made from 100% recycled waste paper fibre acquired from compatible recovery infrastructures throughout North America using a closed loop recycling system. In addition, as part of the closed loop system, Strathcona has arrangements with its customers to have waste clippings of its paperboard products returned to the Strathcona Paper mill as a fibre source. The paper sludge biosolids generated in the manufacture of all of Strathcona Paper’s products including GreenChoice 100 are composted and spread on farmers’ fields as a soil conditioning agent improving water retention in the soil and reducing the amount of commercial fertilizer that the farmer would otherwise have to use.

Community Benefit

The use of GreenChoice 100 as the paperboard substrate in a folding carton allows brand owners to use a number of eco-certified logos: TerraChoice Eco-Logo, GreenChoice 100 Logo and The Environmental Impact Logo on their packaging cartons. The Eco-Logo certifies and informs consumers that any product bearing this logo meets or exceeds a complete environmental lifecycle audit analysis, from energy and material consumed in production through to pollutants generated by their production, use and disposal. In using these eco-certified logos, brand owners have the opportunity to educate and demonstrate their level of responsibility and sustainability at shelf directly to the consumer.

Material Health

GreenChoice 100 is in compliance for direct food contact under the regulatory frameworks of the US Federal Food and Drug Administration Act (FDA), the California EPA Proposition 65 and the Canadian Food Inspection Agency. GreenChoice 100 is also in compliance with the provisions of model state law CONEG, for heavy metal content. GreenChoice 100 is not only 100% recycled and recyclable and carbon neutral, but biodegradable and compostable in the environment. No toxic chemicals are used in the production of GreenChoice 100.

Resource & Energy Optimization

Strathcona’s mill has also reduced the energy consumed per ton of paperboard produced by 15% over the period 2003 to 2007, and carbon dioxide emissions by 14% from 2004 to 2007.

All carbon emissions produced in the manufacture of GreenChoice 100 are offset with the purchase of carbon credits.

Water used in the paperboard manufacturing process is cleaned and returned to the natural water source in a 100% closed loop recycling process. 85% of the water used in the paperboard manufacturing process is recycled, the balance is emitted in the form of steam. Paperboard trim waste produced by converters who purchase Strathcona paperboard substrates is sold back to Strathcona Paper mill for recycling and is backhauled by Strathcona Paper’s transport fleet reducing the transportation involved if it was brokered out to the market.

GreenChoice 100’s proprietary fibre recipes run at one of the lowest conversion rates of fibre to finished board in the industry reducing the amount of waste that would otherwise need to be diverted to landfill.
