Going Green: Striving to Reduce Waste at a Middle School

Posted: Wednesday, October 25th, 2017

Community-based Social Marketing (CBSM) is the current trend in influencing the public to make more eco-friendly choices. Marketing strategies of the past focused solely on dissemination of information while CBSM focuses on removing barriers that make the desired outcome difficult to achieve. This paper details the construction of a CBSM plan to reduce waste sent to the landfill at a public middle school in California. Strategies employed in this CBSM include making the desired action more convenient, prompting, and social diffusion. Strategies for designing your own CBSM plan are also discussed.

The Problem

The planet is currently drowning in human-produced waste, especially plastics. The oceans are congested with pollution, biodiversity on Earth is declining, and the climate is changing (Erikson et al, 2014; Abreo et al, 2015; Javeline, Hellmann, Cornejo, & Shufeldt, 2013). Erikson et al. (2014) found that there is over 250,000 tons of plastic floating on the surface of the world’s oceans. The problem with plastics is not just limited to ocean pollution. Plastics are easily moved by wind and water, take hundreds of years to decompose, and are made from fossil fuels (Jambeck et al., 2015; Baum, Haqq-Misra, & Karmosky, 2012). Diverting or reducing plastic waste is an important topic because of the detrimental effects plastics have on the environment and biodiversity.

Schools are a prime target as sites for waste reduction because of how many people spend their daily lives in a school. In the state of California alone, there are over 6 million students and nearly 300,000 public school teachers (CA Department of Education, 2016). This data does not include students in private schools or non-teaching staff members in schools. Imagine the amount of people who could have a positive environmental impact if school districts around the state were to update procedures regarding waste production and handling.

Community-based social marketing (CBSM) is a strategy that is being used to engage the public in various environmentally-friendly behaviors. Historically, most campaigns that attempted to change individuals’ behaviors focused on education, however, CBSM is a newer strategy that seems to be finding success (McKenzie-Mohr, 2000). The four steps of CBSM will be explained in this paper through the journey of working to reduce waste at a public middle school in California.

Step 1: Research

Conducting research is an important first step in developing a CBSM campaign. Without proper research, it is impossible to know if the cause of an issue is being addressed by the “solutions.” Several layers of research were conducted before beginning the development of this plan. First, observational data was collected of student waste habits in areas where the most waste is generated. Students were observed inside classrooms, outside in the halls, and during lunch. The goal of the observational data was to determine the following things: 1) if students were engaging in recycling; 2) if students were recycling correctly, and 3) what types of items were the most common. The most common waste items would be the target of the CBSM plan.

Another valuable source of data was semi-structured interviews with people who are considered key players in the issue of waste collection and those who are in management roles at the school. Interviews were conducted with the principal, cafeteria manager, and lead custodian. Finally, a literature review was conducted to look for guidance and best practices for moving towards a zero waste lunch, or at least towards waste reduction at school. The research revealed that the most trash appeared to be food waste from the meals students eat at school, so this would be the focus of the CBSM plan. During observations, it was noted that a single student had, on average, seven different waste items after collecting his or her lunch (straw, napkin, plastic utensils, plastic packaging, bowl or wrapper, and paper tray).

In the course of the research, barriers to the desired behaviors were also uncovered. Barriers are the things that may be preventing someone from engaging in the desired behavior — in this case, correctly disposing of lunchtime waste. Many students did not recycle their lunch waste correctly, either dumping all of their waste in the recycle or all in the trash. Another thing commonly observed was students shooting waste at the bins as if they were playing basketball. More often than not, students were shooting their waste at the recycle bin. The recycling cans in the lunch area are the large, rolling type cans, so they are bigger than the trash bins sitting next to them. It seems that the students are shooting their waste at the recycle cans simply because those cans are a larger target.

Once barriers have been uncovered, the target behavior needs to be selected. The target behavior should be one that can overcome the barriers. In this case, the target behavior is getting students to correctly sort their waste into recyclables and landfill material.

Step 2: Plan

An effective plan needs to overcome or even remove barriers. There are several possible tactics to use when designing a CBSM campaign, but the most prominent strategies are removing the barriers by increasing the convenience, creating a social norm, and prompting. When designing a CBSM plan, a person can employ more than one strategy for the greatest chance of success. In this example, the first strategy was convenience – making it simple for students to do the correct thing. Pike et al. (2003) found that student participation in recycling was significantly greater when students were provided with an opportunity to recycle along with education about how to recycle. In the lunch area, every trash can was placed next to a recycling bin, eliminating the need for students to walk around in search of a recycling bin. Next, prompts were placed on each bin directing students what goes in each container the prompts were specific to the items students actually have with them for lunch. For example, in the trash bin, there is an image of the plastic spoon students are given with their lunch, while on the recycling bin is an image of the recyclable plastic bowls. Similar prompts were also created for the classroom recycling bins. Inside each classroom, there is a small paper bin, and a larger bottle and can bin. Students are frequently confused as to what goes in each bin, so this can be simplified with a large, graphic prompt indicating what is to be placed in each bin. According to Kelly, Pechmann, and Reibling (2010), school-based social marketing plans are only successful when the campaign is implemented with fidelity and all participants are on board. To be sure a plan goes well, there needs to be open and clear communication between all involved parties (Hemmert, 2004).

Step 3: Pilot

Once your plan has been developed it has to be tested! It is best, to begin with a limited pilot of the plan, so any problems can be addressed and corrected before the plan is broadly implemented. If the pilot of a CBSM plan is successful, then the campaign can be spread widely; if the plan is not successful then it is necessary to head back to the drawing board, revise the plan, and pilot again.

Step 4: Evaluate

One critical component of CBSM is a method for evaluating the campaign. How will success be measured? In the example described above, evaluation was quantitative data collected by the school district which measured the percent of waste that was diverted from the landfill. When measuring the success of a CBSM campaign, it is important to have actual data to analyze, and not to just rely on what people report they are doing.

Going further

The goal of this CBSM plan was to divert waste from the local landfill as quickly as possible, given more time, permanent steps could be taken to make a positive impact on the waste produced at school.  Suggestions for making a longer lasting impact include changing the way food is packaged at school or getting compostable utensils instead of plastics, but CBSM is a great way to quickly make an impact.

NGSS – Early Attempts and Later Reflections from an Early Implementer Teacher

Posted: Thursday, November 23rd, 2017

by Christa Dunkel

  • There are so many acronyms! Where do I start?
  • What “baby step” should I take first? 
  • How can I make this happen in my elementary classroom?

All of these thoughts and more swam through my head over three years ago when I began my journey into NGSS. I was fresh from a week-long institute with the K-12 Alliance as part of the CA NGSS K-8 Early Implementation Initiative. Much of the week was spent on digging into the NGSS architecture – how the standards are set-up, how to read the standards, what each of the three dimensions meant. Now that I knew how to read them, I needed to figure out how to implement them into my classroom of 24 eight-year-olds. With some guidance from the K-12 Alliance leaders and my own district-level NGSS team, I began the process with some easy “baby steps.” Learn More…
