Case Study: Ending single-use plastics at Walnut Studiolo

We experience plastic trash on our local beach every week. Now inspired by recent news reports and nature documentaries, we’re taking a stand. Walnut is committing here and now to eliminating single-use plastics in our product packaging – no more new single-use plastic purchases going forward – and we’re reducing plastics everywhere else in our business, too. Here are our reasons why and how – plus a little on how you can help, too.

Why we’re eliminating single-use plastics

We live and work near the ocean, and we experience plastic debris on our beaches. We know how big the problem is. We do our part and help at beach clean-up days but the sheer quantity of tiny plastics is overwhelming.  Meanwhile, although we already operate by strong sustainability values, we realize there are improvements we can make in the use of plastics.

There are two main plastics problems: 1) not enough durability / reuse / recycling of plastic goods, and 2) the sheer volume of plastics that are designed to be destroyed and disposed after only one use (“single-use plastics”). We don’t make plastic goods anyway, but the UN has made it easy for us: they prioritized the elimination of single-use plastics as our first, top priority – for the oceans, for the food chain, and for our own health.

Plastic packaging accounts for nearly half of all plastic waste globally, and much of it is thrown away within just a few minutes of its first use. Much plastic may be single-use, but that does not mean it is easily disposable. When discarded in landfills or in the environment, plastic can take up to a thousand years to decompose.

The most common single-use plastics found in the environment are, in order of magnitude, cigarette butts, plastic drinking bottles, plastic bottle caps, food wrappers, plastic grocery bags, plastic lids, straws and stirrers, other types of plastic bags, and foam take-away containers.

Single-Use Plastics: A Road Map to Sustainability, UN Environment Program Report, 2018

We used the UN Report’s road map to help guide our program to end single-use plastics, focusing on the products we send out first, with an extension goal of reducing what we bring in and use for our operations.


How we’re eliminating single-use plastics

1. Identify the most problematic single-use plastics in your business

As a small operation focusing on products made from natural materials, this was relatively straightforward: to inventory our plastics, we reviewed our finished goods and raw materials inventory lists and did a walk-through of our operations areas.  Conclusion: Plastics come to us via suppliers as part of our raw materials and operations – such as packages of screws or food supplies in the office – and we purchase and send out plastics out to our customers with our products as packaging and shipping materials.

Clearly the most problematic single-use plastics are the ones we choose to buy and send out to our customers for our products.

  • Packaging: This is the main area where we purchase and use single-use plastics. We already use recycled paper packaging for most of our products, but nonetheless we do use plastic bags for a few of our products: the most go into drawer pull hardware kits.  This is thus the most problematic area of our business and where we can have the greatest impact.
  • Shipping: We use up-cycled / reused shipping materials first (as much as available), then we rely on newly-purchased shipping materials. Most shipping materials are made of recycled paper such as boxes, but we do also use bubble mailers, which have a plastic bubble sleeve on the inside of a recycled kraft paper exterior; recycled plastic poly mailers from EcoEnclose, and plastic bubble wrap. All of the plastic shipping materials can be re-used (we re-use the ones that come to us), and we feel okay about creating demand for recycled plastics by choosing recycled poly mailers, but we can have an impact by choosing less plastic material in our shipping.

2. Consider and implement the best actions to tackle the problem.

    1. Walnut is committing here and now to eliminating single-use plastic bags in our product packaging – no more new single-use plastic purchases going forward. We have identified recycled kraft coin envelopes and wax paper sleeves as biodegradable alternatives. These paper alternatives will cost slightly more but the additional cost is insignificant to our material costs and will not change product prices.
    2. Walnut will reduce reusable plastic bags in our product packaging. We have identified recycled kraft merchandise bags and wax paper sleeves as biodegradable alternatives. In some cases these paper alternatives are actually less expensive than plastics, and in other cases, the additional cost is insignificant to product pricing.
    3. Walnut will also reduce reusable plastic packaging in our shipping materials. We will trade plastic bubble wrap for kraft “green wrap.” Finding a non-plastic, lightweight, cost-absorbable alternative to the bubble mailer is our next priority.
    4. Walnut will strive to reduce single-use plastics in our material purchasing and operations choices as much as possible, such as buying materials in bulk and implementing a loose tea bar in our office.
    5. Walnut will keep this program going by having one point person dedicated to this initiative who will review and research all sourcing choices.


How you can reduce single-use plastics

We are writing this blog post today because we want to raise public awareness about single-use plastics. We were inspired to do this after reading the UN report and watching David Attenborough’s Blue Planet II while stitching together our leather goods one night. We hope that by adapting the UN’s single-use plastics road map to a small business and providing our analysis transparently, we can provide a model for other small businesses to crib.

Here’s what you can do to help: 

  • Check out the Resources section below to learn more
  • Support businesses who are doing their part to reduce single-use plastics
  • Share this article with other small businesses
  • Recycle and reuse your shipping materials:
    • Cardboard boxes can be recycled
    • Clean packaging peanuts can be brought to participating UPS stores for re-use
    • Consider opening your plastic bubble mailers and poly mailers gently and offer them to their local businesses for re-use. Bubble mailers and poly mailers are often thrown away, but if you know a friend with a small business like an Etsy shop, they may be happy to use them as we were. Our local craft re-use center, SCRAP PDX, could hardly keep enough used bubble mailers in stock at one point!

How to open your mailers for re-use:

To open a bubble mailer or poly mailer so that it can be re-used, resist the temptation to rip or tear apart. Take out scissors and either:
a) cut cleanly across the top of the package, or
b) score the tape with the scissors and open at the tape line, or
c) slide the scissors underneath the envelope flap and cut right above the glue line.

The goal is for the next user to simply re-tape it shut in the same place it was first taped or cut.



The planning of this program and this exercise took us about five hours, and was totally worth the thought exercise. By looking at everything we do, it challenged us to make improvements we might not have considered before. It also helped us really hone in on the most problematic plastics in our business and identify our highest priorities, so that finding implementable solutions was relatively easy because the list was short. How do you eat an elephant? One bite at a time. We were surprised and pleased to find out we could eliminate the worst plastics in our business for either insignificant cost increases or actual cost savings. Most of these changes we can implement immediately and with surprisingly little effort.

  1. Thank you for this information. I am reading the UN Report, summarizing some relevant facts and will post it on Facebook. I appreciate that as a small business, you’re looking at your impact on the environment. Excellent blog post!

  2. […] In 2019, following the UN guidelines, we embarked on a transparent and singularly-focused initiative to end single-use plastics at all stages of operation at Walnut Studiolo. As of this writing, we have successfully eliminated single-use plastics from all of our packaging and products and we continue to seek out better sources for our operations. (How did we eliminate single-use plastics?) […]
