Keep Plastic Out of the Green Bin! A new anti-contamination campaign to improve compost quality

Lisa Duba

This past year, we accepted the challenge to help San Mateo County develop a countywide social marketing campaign designed to improve compost quality by addressing contamination of food scraps and yard trimmings collected in the county.

The Project

Farmer: we need you help making healthy compostGigantic Idea Studio developed a scope of work that included as much of the community-based social marketing (CBSM) process as time and budget would allow:

  • Secondary research review of data from haulers, public agency RethinkWaste, transfer stations and composting facilities and similar campaigns,
  • Primary research via focus groups, with message development and testing and finally,
  • Campaign creative and a pilot study toolkit, with an implementation guide.

Partnering for Success

Gigantic partnered with R3 Consulting Group to analyze data and identify the top contaminants and sources of contamination. Unsurprisingly, plastics, especially film plastics, were most common. Multi-family dwellings (MFDs) and commercial businesses were the top sources. To keep within the time and budget, we chose plastic as the target contaminant, and MFDs as the target audience.

We also partnered with Green Motivate to look at messaging of similar campaigns conducted in Vermont; Boulder, Colorado; Oregon and Snohomish County, Washington. Each had compelling messages and images— some of which inspired our campaign.

Contaminated green bin means contaminated compostPartnering with Engel Research Partners, we conducted focus groups in English, Spanish and Cantonese to test selected messages and learn more about the barriers and benefits related to food scrap and yard trimming collection programs.

Top Takeaways

  • Most people were unclear about what happens to the contents of their green bins after they are collected.
  • Once they understood that compost was used in gardens, parks and farms, residents seemed more motivated to learn how to prevent contamination.
  • Motivating messages included links to local agriculture, farmers/farmworkers and health.
  • But people also wanted clear, easy to understand instructions on how to compost correctly— not just inspiration and fluff.
  • Bin is the preferred term (vs. carts) to refer to wheeled carts and larger rolloff bins.

From these learnings we created a messaging strategy to inform a storytelling video, article and social media posts that included:

  • Awareness messaging: “Contaminated Green Bin=Contaminate Compost”
  • Motivational messaging: “We need your help making healthy compost for San Mateo County gardens, parks and farms,” and
  • Food in, plastic out - green cartInstructional messaging: “Keep All Plastic Out of the Green Bin” and “Food In/Plastic Out”.

For on-the-ground interventions, the campaign toolkit also included bin area signage, a downloadable kitchen sign, and a pilot study methodology.  To reach the top monolingual, non-English speaking communities, we partnered with InterEthnica to adapt all campaign collateral into Spanish and Chinese.

While the CBSM components will be implemented locally by stakeholders, the County will be doing a media campaign to support on-the-ground efforts, running sometime this fall.

Lizzie Carrade of the San Mateo County Sustainability Department presented the campaign at the California Resource Recovery Association Annual Conference this year. We are proud to have been part of the team trying to address this pervasive problem.

 

Garden Pots and Mulch Bags, OH MY!

Kas Neteler

On a recent chilly early Monday morning in March, Stef and I were conducting spot checks* for our client, Livermore Recycles. In a single lid-flipping morning, we walk several miles and record data on approximately 200 residential trash/recycling/composting set-outs. I flip the lid on each cart and call out what I see while Stef records the data on her clipboard.

On this morning, a pattern was beginning to emerge. From the compost cart we could tell folks were definitely working on their gardens and yards this time of year AND some of them were confused about where their nursery pots and mulch bags should end up. Unfortunately, film plastics such as mulch bags and those black flimsy pots belong in the trash – we found several set-outs where these items were contaminating the organics cart and the recycling cart.

As a result of seeing this in the field on Monday, and verifying with the team that this continued throughout the week, we were able to create a social media post prior to the next weekend to let Livermore residents know:

We were quite pleased when we saw the comments and likes come in:

I’d call that a Gigantic success and a good example of how we can act upon what we see is needed in a short amount of time.

*Gigantic Idea Studio, has been flipping lids in Livermore twice a year (Spring and Fall since 2017. This involves early morning starts to stay ahead of the Livermore Sanitation trucks as we flip lids on approximately 1,000 setouts during a single week. The data is collected, reviewed and reported back to the client, along with recommendations for messaging specific to Livermore residents’ needs.

Recycling Realities: How to Create Anti-Contamination Messaging

Lisa Duba

 

There has been a lot of media coverage lately about the problems and challenges of recycling, including the rejection of the tons of recyclables that we used to ship to China. Because of the news, many community members are aware that something bad is going on with recycling.

In our presentation at California Resource Recovery Association (CRRA) on August 12 in Rancho Mirage, California, I presented some notable examples of anti-contamination recycling messages by haulers, as well as our own work tackling these issues in Palo Alto and Livermore.

items prepped for recycling or rejected

We based our work on actual recycling realities in each city. In Palo Alto, the contamination was focused on food and liquid in recycling. In Livermore, sorting issues (“Wishcycling”) as well as organics cart contamination were affecting the quality of the recycling stream. These findings informed our social media, newsletter content and campaign concept development.

Clearly presented information, using clear calls to action (Wipe, Pour, Scrape, etc.) and good visuals is a start to tackling the problem. Reaching residents using a multi-channel approach, and repeating the message regularly will help get the word out.

Recycling Spot Checks: Flipping Lids in Livermore

Kas Neteler

During the last week of September, my colleague Stefanie Pruegel (pictured left) and I (pictured right) donned orange safety vests and set out before sunrise to study recycling program participation in various neighborhoods in Livermore, California. Armed with headlamps, clipboards and maps, we walked some 20 miles over five days and flipped about 2,000 recycling and organics cart lids.

This walkabout was part of our observational research to gain insights into residents’ recycling and composting habits, including contamination patterns (i.e., putting things in the wrong carts). The data we gathered will also measure the baseline participation rate. Repeating this measurement after an outreach campaign will allow us to compare the results and determine how successful we were as well as guide the next phase of outreach. This particular kind of measurement can be a messy job, but someone’s gotta do it.

During our lid-flipping adventures, several patterns emerged:

• Livermore loves pizza and is confused about leftovers.  In Livermore, the proper process is to chuck pizza boxes and leftovers into the Organics (compost) cart. Pizza boxes are considered food-soiled paper (as are most fast food paper wrappers), and pizza crusts are considered food scraps – all of which goes into Organics. However, we found households were evenly split over whether to put the box in Recycling or Organics.

• Livermore is a thirsty bunch, and cup sorting is a challenge.  What is the preferred destination for takeout cups, lids and straws? These items are made of both plastic and paper, and each needs to be handled IMG_2610differently. This leads to a lot of consumer confusion. We found that no matter if the cups were for cold drinks (plastic) or hot drinks, (paper) the majority ended up in the recycling cart, along with their lids and straws. But, the lids and straws actually go into the garbage, and the paper cups go in the organics. This kind of contamination adds considerable expense for waste haulers and ultimately can drive up trash rates. (Please Note: This is a general observation and not a prediction for Livermore.)

• Livermore has beautiful yards, and sorting the waste is a conundrum.  Throughout the week we “ooh-ed” and “ah-ed” at the beautiful yards and landscaping in the neighborhoods we saw. However, many residents seemed to assume that anything from the yard belongs in the Organics cart. In fact, certain items like pet waste belongs in Garbage, not Organics. Putting whatever blows (or gets pooped) in people’s yards into the Organics cart causes another costly contamination headache.

We saw some clear consistencies in what was going right and wrong in the carts. Next we will tabulate our findings, design an outreach campaign to focus on the most prevalent behaviors that need to change, and afterwards, check those carts again. We look forward to helping the city and the citizens of Livermore “sort out” any issues and move forward with their waste reduction goals.
