Guest Blog Addressing the Challenges of Measuring Recycling Performance

Posted by GlobalPSC at 4:45 pm, June 8th, 2016Comments0

The Global Product Stewardship Council periodically invites thought leaders on product stewardship and producer responsibility to contribute guest blogs. Our guest blogger for this post is Carl Smith, President and CEO of Call2Recycle, Inc.

Prior to becoming the head of a non-profit 12 years ago, I had spent most of my career with big for-profit companies where we measured everything. These measures provided continuous feedback on what was working and what needed to be fixed (or stopped). Upon arriving in the non-profit, product stewardship world, I noted that much less was measured and that organizational performance metrics were at best elusive.

One of the biggest frustrations we have is how to accurately assess the performance of our battery recycling efforts. The recycling field has typically relied on “diversion rates” as a measure; specific to battery collection and recycling, the more specific “collection rate” measure is typically used. As has been defined by the EU, battery collection rate is defined by the amount recycled in a year divided by the average annual sales of batteries for the previous three years. Like “diversion rates”, a “collection rate” is expressed as a percentage.

Traditionally, the focus of the Call2Recycle® program in the US has been on collecting and recycling rechargeable batteries. For a variety of reasons, this ‘typical’ approach to measuring our performance simply didn’t make sense.

First, fairly soon after I took this position, it became clear that rechargeable battery companies simply do not know what their consumer battery sales are into any specific jurisdiction. There are simply too many channels, applications and value chains to even estimate sales. For a very simple example, let’s look at how a big retailer like Walmart operates in the US. It purchases in vast quantities directly from a manufacturing facility in Asia. The facility transports via container ship to a West Coast port where they are then trucked to a distribution facility in a Midwestern state. Given the North American Fair Trade Agreement (NAFTA), units could also be shipped to distribution centers in Canada and Mexico. Those distributions centers then fulfill store orders on a ‘just in time’ basis. So if you asked the manufacturer how many batteries it has sold in, for instance, the state of Vermont, it won’t know. It sold to Walmart and where they actually appeared in the US market is a mystery to them.

Second, the rechargeable batteries we’re collecting today are likely 5, 10 or even 20 years old. On average, they were certainly not sold during the three-year window that a typical collection rate calculation would measure. A related issue to this is the general inclination that consumers “hoard” electronics and batteries long after their useful life. How many old cellphones do you have sitting in a drawer? When is the last time you used your first power tool?

These issues are particularly difficult for rechargeable batteries which generally last longer than primary batteries, are hoarded more (with the products they power) and are sold through much more complex value chains. So the conventional approach to assessing our performance using a collection rate just didn’t work.

We commissioned a study to see if we could develop a methodology that was repeatable, credible and defensible that would provide us more insight into this issue. When we started the study, we focused on two stages:,

  1. develop a way of accurately measuring battery sales; and
  2. adjust sales for the lifespan of the batteries.

The more we immersed ourselves into this subject, a third issue emerged that was in the initial research requirements.

Increasingly, rechargeable batteries are designed so that they cannot be easily removed by the consumer, which generally means that they are not typically available to be recycled. Cellphones, tablets and laptops are the most obvious examples of this. But how about electric toothbrushes and cordless shavers? Even when the host product is recycled by, let’s say, an electronics recycler, the batteries are not typically the material most coveted in the process. Therefore, even if they are technically recycled with the host product, the process has not often been optimized to reclaim the precious material in the battery.

We maintain that embedded batteries are not generally available for collection by a battery stewardship program and should be excluded from the calculation of “collection rate”. So we added a third stage of this research: adjust sales downward by the amount of embedded batteries in order to determine an accurate assessment of the amount of batteries truly available for collection.

The outcome of this research – the paper available via this link – shows our results. It gives us a new denominator called “available for collection” that would replace the EU standards of the average of the last three years’ sales. In the end, we now say:

Collection Rate = Batteries Collected / Sales (Lifespan) – Embedded Batteries

In addition to the important data generated through this research, we came away with four important observations consistent with the conversation above:

  • For primary batteries, battery sales from “bricks and mortar” retail locations are less and less of the total market. There are many more diverse channels for batteries to enter the marketplace including, in particular, on-line markets.
  • A new method for measuring collection rates is needed for rechargeable batteries to measure collection performance. Such a method must meaningfully capture longer battery and product lifecycles and increases in embedded batteries.
  • While some but not all of the products that rechargeable batteries power are managed through other stewardship programs, they are generally getting “lost” in tracking performance.
  • It is imperative that collection programs incorporate long product lifecycles into their funding models, as batteries remain in market long after they are sold.

The last point is notable. Most battery stewardship programs charge stewards based on sales into the market. However, there may be a 20-year lag time between when steward fees are paid on a sale and when we incur the cost to collect and recycle the battery from that sale. This puts a strain on funding models that are often forced to minimize reserves that might take care of the long-term “tail” associated with rechargeable batteries.

In the end, we felt we “moved the needle” on creating a better way to measure performance. We also added to the conversation on the issues associated with battery collection and recycling. But we don’t believe we’ve totally solved the challenges, hopefully giving others the opportunity to contribute to this discussion.

The views expressed do not necessarily reflect those of the Global Product Stewardship Council.
