As consumer preferences continue to shift, with more people seeking eco friendly, sustainable packaging in the products they buy, some of the world’s biggest retailers are taking note. Both Walmart and Amazon, for instance, have launched comprehensive packaging sustainability initiatives.

Walmart’s Packaging Scorecard

Just over a decade ago, Walmart introduced their proprietary Packaging Scorecard to companies throughout their supply chain.

RELATED: Biodegradable vs. Compostable vs. Recyclable – How to Choose the Right Packaging

Working with guidelines established by the Packaging Sustainable Value Network, a group of leading companies in the packaging industry, Walmart’s Packaging Scorecard identified nine key metrics to consider when designing and creating eco friendly packaging:

1. Greenhouse gas/CO2 generation per ton of packaging produced
2. Material value
3. Product-to-package ratio
4. Cube utilization
5. Transportation
6. Recycled content
7. Recovery value
8. Renewable energy use
9. Innovation

Each of these environmentally relevant metrics is represented as a percentage of 100 possible points for rating existing packaging, developing new packaging, and comparing one’s own environmentally friendly packaging solutions to those of other companies.

Walmart doubled down on their sustainable initiatives in 2016 when they released their Sustainable Packaging Playbook — which focuses on optimizing packaging design, securing sustainable material sources, and supporting recycling — to help guide companies toward methods for improvement.

Amazon’s Certification Guidelines

Walmart is not alone in recognizing the importance of sustainable packaging, both for the environment and manufacturer ROI. In 2008, Amazon, the world’s largest online retailers, introduced their own eco friendly packaging initiative, the Frustration-Free Packaging Program.

Frustration-Free Packaging takes a more consumer-oriented approach — its main goal is to ease “wrap rage,” the frustration that consumers often feel when faced with excessive amounts of packaging materials or difficult-to-open designs.

The program aims to drastically reduce the number of boxes used in shipping, as well as packaging materials in general, such as clamshells, wire ties, and plastic bindings. By putting a focus on material reduction and recyclability, Frustration-Free Packaging is also eco friendly packaging.

Taking the Eco-Friendly Packaging Leap

Manufacturers large and small, and from all types of industries, are increasingly adopting the sustainable packaging requirements set into motion by mega-retailers like Walmart and Amazon.

These practices are often considered to be cost-ineffective for manufacturers, but with the right amount of research and analysis, environmentally friendly packaging practices can actually lead to significant cost savings.

For many years, plastic has been the standard in packaging. As concerns mount over environmental issues, however, there’s increasing demand for sustainable alternatives.

In some cities, such as San Francisco, governments are passing legislation that bans the use of plastic bags, while many retailers are proactively taking steps to “go green.” Popular food retailer Whole Foods, for instance, no longer uses plastic bags, and 60% of Apple’s paper packaging is now made from recycled wood fibers.

According to a recent survey, over half of American consumers said they would choose green products over conventional options if given the choice.

Green packaging is no longer just a niche marketing tactic; with long-term benefits easily outweighing the added costs, they’re imperative for remaining competitive in today’s changing landscape.

Making the decision to go green is simple. Understanding the various packaging options, costs, and marketing claims is often a challenge for brand owners.

Sierra Coating has been researching and working with poly replacement alternatives for years. Our team can shorten the product development stage by having already screened and tested a number of market-ready alternatives.

When developing an eco friendly package, it’s important to consider the specific usage standards that your application requires as well as material disposal methods.

The Ideal Solution

When choosing between biodegradable, compostable, and recyclable packaging; it’s important to ensure the chosen material does, in fact, reduce waste efficiently and effectively.

At current standards, there are three optimal solutions for creating an eco friendly package:

1. Make the package smaller to reduce your footprint
2. Utilize recycled materials to create the package
3. Create a recyclable package that can be disposed of in a sustainable manner

For many packaging applications, paper is an ideal solution. Folding cartons are ubiquitous; they are used to ship everything from electronics to pharmaceuticals and provide a sustainable, customer-friendly experience.

Folding cartons can be made out of recycled materials and coated with environmentally-sustainable barrier coatings. Not only is folding carton sturdy, lightweight, and customizable; it’s also cost efficient.

Eco-Friendly Packaging and Disposal Options

Compostable Packaging’s Geographic Limitations

When disposed of properly, compostable products will break down through microbial digestion into humus, providing valuable nutrients to the soil without releasing toxins or metals.

Under the right conditions, this process takes approximately 180 days. However, this is rarely the case. According to ASTM standards, compostable products must be disposed of at a municipal or industrial facility that uses heat to properly break down the product.

Retailers rarely have control over consumers’ disposal methods. Compost facilities are usually located in major cities, limiting the impact and effectiveness of a brand’s sustainability effort.

More often than not, materials end up in trash cans and eventually in landfills, which are not conducive to the sustainability goal of the compostable package.

Biodegradable Packaging’s Greenwashing Association

Biodegradable packaging materials are broken down by bacteria, fungi, or other microorganisms. This occurs through either anaerobic (without oxygen) or aerobic (with oxygen) degradation.

Unlike other sustainable products, biodegradable materials are not required to meet any specific industry standards or regulations.

And because virtually everything is biodegradable, whether it happens in one year or 100, marketers often exaggerate claims of biodegradability. In fact, the ubiquity of the term has come to be associated with “greenwashing,” misleading consumers about the true environmental impact.

To combat this, the Federal Trade Commission (FTC) has set forth the Green Guidelines as a benchmark for marketers.

These guidelines state that a biodegradable product “will completely break down and return to nature within a reasonably short period of time after customer disposal.” However, the FTC has yet to pinpoint what is considered a reasonably short period.

Recyclable Packaging: The Most Eco Friendly Option

Recyclable packaging, on the other hand, can be remanufactured into something new after its initial use. Similar to composting, the efficacy of recycling depends on a number of factors.

First, the end user must make the decision to recycle the product, and their recycling center must have the capabilities to recycle that specific material. (Recycling guidelines can vary greatly by region). Also, the product cannot contain any food contamination.

When these requirements are met, recyclable packaging is often the most eco friendly option, since it allows the material to be reused for the same purpose.

Although recycled material requires energy, it still increases the overall product lifecycle. Manufacturers can also take more responsibility themselves by using recycled material as an input of the base product, rather than relying solely on the consumer to recycle.

The Move to Eco-Friendly Packaging

Over the past several years, businesses across multiple industries have taken a growing interest in environmental sustainability. The packaging industry plays a critical role in this movement, as packaging is often the first thing a customer notices about a product. As such, companies are tasked with reconciling environmentally-conscious material selections with cost-effective production.

Petroleum-based plastics, though affordable and easily sourced, are nearly impossible to recycle, The Guardian recently explained; they litter the Earth and pollute oceans forever without biodegrading. Instead, packaging companies must seek out alternatives to create more sustainable solutions. Even candy manufacturers are now looking for eco-friendly wrappers, using wood-based materials and non-toxic ink to create a compostable solution.

Replacing PVC and Plastics in Packaging

Recognizing this shift toward sustainability, Sierra is seeing a growing opportunity to replace polyvinyl chloride (PVC) and other harmful plastics with greener, biodegradable package made with paper. This is especially relevant to blister packaging; because it cannot be recycled due to mixed material limitations, the packaging tends to wind up in landfills.

PVC and low-density polyethylene (LDPE) resins, found in many of today’s packages, are neither recyclable nor biodegradable due to their use in a package design. When exposed to high temperatures, these wrappers can also release toxic fumes and dangerous chemicals into the environment.

Plastics, which for many years held the advantage over paper for being heat sealable, have finally met their match. Sierra has developed innovative paper-based blister pack technology to reduce or replace PVC, LDPE, and other harmful plastics commonly used in packaging structures.

These paper-based recyclable coatings provide protective features that can compete with traditional packaging — but without the negative side effects. Both environmentally friendly and affordable, Sierra’s blister packs can be heat sealed while still allowing products to biodegrade much more easily. These state-of-the-art “green” coatings can be used to design packages that reduce PVC or replace poly coatings.

Creating a Cost-Effective Poly Replacement

Many companies are seeking affordable poly-replacement materials that will allow their packages to biodegrade, allowing them to position their products as environmentally friendly. For decades, this was a high-priced specialty order, but now Sierra is working on closing the gap on cost-effective poly replacements with paper-based packaging like blister packs.

Until recently, green packaging solutions only existed on a small scale due to relatively higher costs compared to polys.  As more brand owners respond to customer desires for an environmental solution, innovation has created alternative options that are reducing costs.  Sierra continues to source and test these innovative coatings to drive this technology into the mainstream.

There is nothing like smelling a forest filled with beautiful plastic pine trees on a cool fall day. Wait. OK how about going green by planting five plastic trees for everyone you cut down? No, that doesn’t work either.

The point? No matter how many “green” and “recycled” labels you slap on petroleum-based plastic products, they cannot and will never be as renewable as paper. Unlike trees, oil and gas don’t put C0₂ back into the atmosphere and trees are a homegrown product that unlike plastic are not beholden to the ups and downs of oil and gas prices.

If it is both more environmentally friendly and often more affordable, why aren’t more things made out of paper? One of the main reasons has always been that plastic outperforms paper at some tasks, like waterproofing and sealing.

At Sierra, thanks to our innovative technology and methods we are bridging this ever-shrinking performance gap everyday.  Sierra is able to coat the back or front of paper in order to enhance its ability. A great example is food and cleaning product packaging. Sierra can create water barriers and heat sealed packages, all with our state-of-the-art recyclable coatings. It is hard to be more “green” then replacing PVC and other plastics with recyclable paper.

One of the other benefits to using paper is that major retailers like Walmart are now demanding that products reach very high standards of recyclability. The Walmart Sustainability Index  grades the “Greenness” of products, if you don’t get a high enough index score, your product will not end up on the shelves of the world’s biggest retailers, and no one can afford for that to happen! Once again, the solution is paper, and thanks to Sierra, you can now easily replace plastics with coated paper products and suffer no fall-off in quality.

The next time you think you have no choice but to use hard or impossible to recycle plastics in your packaging, think again.

Think Green. Think Affordable. Think Effective. Think Paper.
