2007 Statewide Recycling Rate for Plastic Carryout Bags

Reporting period: July 1, 2007-Dec. 31, 2007

Summary

The 2007 statewide recycling rate for regulated plastic carryout bags is about 2 percent. During this reporting period, which only represents the last six months of the year (July 1-Dec. 31), regulated stores (defined below) purchased about 24,600  tons of regulated plastic carryout bags and collected about 470 tons of these bags for recycling. The recycling rate was calculated by dividing the total amount of regulated bags collected for recycling by the total amount purchased.

The recycling rate calculation is based on data from the annual reports submitted by regulated stores as modified by the results of the California State University at Sacramento’s “2010 Characterization Study to Determine the Plastic Carryout Bag Commingled Recycling Rates” (CSUS Characterization Study). Many of the largest store chains declined to participate in the CSUS Characterization Study, which limits the representativeness of the data as well as the accuracy of the statewide recycling rate.

Background

California’s At-Store Recycling Program was established in 2006 by the passage of AB 2449 (Levine, Chapter 845, Statutes of 2006). This law applies to supermarkets (with gross annual sales of $2 million or more and that sells a line of dry groceries, canned goods, non-food items, or perishable goods) and other retail establishments (that have over 10,000 square feet of retail space that generate sales tax and have a licensed pharmacy), that provide plastic carryout bags at the point of sale to customers. The law requires regulated stores to establish a plastic carryout bag recycling program. Other retail establishments that do not fall under the law may also choose to voluntarily participate in this statewide program.

In 2007, the California Integrated Waste Management Board (now the Department of Resources Recycling and Recovery, or CalRecycle) adopted regulations that require regulated store operators to maintain records and submit annual reports to CalRecycle about the collection, transportation, and recycling of regulated plastic carryout bags. The regulations allow operators to report the weight of plastic carryout bags recycled or the weight of the bags commingled with other film plastic that is being recycled. Further, the regulations require CalRecycle to develop and publish a recycling rate for the commingled plastic film.

Analysis

For 2007, store operators, representing 4,059 stores in California, reported that they purchased about 24,600 tons of regulated plastic carryout bags. Two stores reported they did not purchase plastic carryout bags.

  • About 36 percent of stores reported that their recycling programs collected only plastic carryout bags ("bags-only").
  • About 52 percent of stores reported collecting plastic carryout bags commingled with other plastic material ("commingled").
  • About 10 percent reported collecting plastic carryout bags using both methods.
  • The remaining 2 percent either did not report recycling or did not report the weight of bags purchased.

*Note: Two (2) stores did not report the weight of bags purchased. Results may vary due to rounding.

To determine how much of the collected material sent to recycling was regulated plastic carryout bags, CalRecycle staff applied the adjustment factors established by the CSUS Characterization Study to the reported amounts collected. The "bags-only" and "commingled" collection methods each have their own adjustment factors as established by the study. The CSUS Characterization Study found that:

  • Bags-only method: Of the 1,328 tons reported as collected using this method, only 11 percent of this material were regulated bags and about 89 percent were either non-regulated bags or other plastic material and contaminants.
  • Commingled method: Of the 5,494 tons reported as collected using this method, about 6 percent of this material were regulated bags and about 94 percent were either non-regulated bags or other plastic material and contaminants.

Recycling Rate

The 2007 statewide recycling rate for regulated plastic carryout bags, which only represents the last six months of the year (July 1-Dec. 31), was calculated by dividing the total amount of regulated bags collected for recycling (470 tons) by the total amount of regulated bags purchased (24,600 tons). The resulting recycling rate is about 2 percent.

Data Limitations

Not all store operators submitted annual reports despite receiving notices that reports were due. Therefore, there are likely more regulated stores in California than reported to CalRecycle.

The regulations also allow a designated reporting party to submit a report on behalf of a store operator. While this makes it easier for store operators to submit their reports, sometimes both the store and a designated reporting party submitted a report to CalRecycle. Also, some reports by designated reporting parties included several operators but did not specify which stores were included for which operator.

Many of the largest store chains declined to participate in the CSUS Characterization Study, which limits the representativeness of the data, as well as the overall accuracy of the statewide recycling rate.

Collectors and Recyclers

The 2007 annual reports identified 72 entities that either collected and/or recycled regulated plastic carryout bags. The entities included:

  • Businesses (for example, plastic bag brokers, distributors, and plastic reprocessors).
  • Local waste haulers and municipalities.
  • Nonprofits.
  • Elementary schools.
  • Other regulated stores.

Some of the products made from the recycled plastic carryout bags included new plastic bags, film plastic, and plastic lumber.

Detailed Findings

The following summary contains more detailed information than presented above in Tables 1 and 2.

In this summary, store operators are grouped together by size in order to differentiate their reporting results. The size of an operator is determined by the number of stores represented in their report. The number of stores illustrates differences between operators due to their quantities of plastic carryout bags purchased and recycled. Store operator categories are:

  • Small – One (1) reported store location.
  • Medium – Between two and ten (2-10) stores.
  • Large – Between 11-100 stores.
  • Extra Large – More than 100 stores.
  • Non-Responsive – Store operators with an unknown number of store locations due to lack of a store list within the annual report.

Note: A number of annual reports did not include complete information for all sections. Therefore the number of store operators included in the analysis below varies.

Table 3 provides a summary of the total number of store locations, within each size category, that reported purchasing regulated plastic carryout bags for distribution.

Total 4,059

Figure 1 depicts the percentage distribution of stores from Table 3 by store operator category. This figure does not include the non-responsive store operators who have not submitted a list of store locations. The store operators that comprise the extra-large category account for 92 percent of the total reported stores.

Table 4 is a summary of the methods used by the 204 store operators who reported to CalRecycle to collect and recycle or send for recycling their regulated plastic carryout bags. Store operators that used both bags-only and commingled methods to report their recycling are identified as “Both Methods.”

Reported Collection Method Number of Store Operators
Bags-Only 166
Commingled 21
Both Methods 17

Table 5 presents a breakdown of all plastic materials collected for recycling using the bags-only collection method. The table provides a breakdown within the following three categories based on the CSUS findings:

  • Regulated bags: Plastic carryout bags that bear the “PLEASE RETURN TO A PARTICIPATING STORE FOR RECYCLING” notice.
  • Non-Regulated bags: Plastic carryout bags that do not bear the “PLEASE RETURN TO A PARTICIPATING STORE FOR RECYCLING” notice.
  • Other Plastic Material: Durable plastic items such as, but not limited to, bottles, hangers, tubs and pails.

The results show that in 2007, of the 1,328 tons reported as collected for recycling using the bags-only method, only 145 tons of regulated plastic carryout bags were collected.

Table 6 presents a breakdown of all plastic materials collected for recycling using the commingled collection method. The table provides a breakdown within the following five categories based on the CSUS findings. Note: Data reported above in Table 2 as Non-Regulated Bags is further broken down here as "Non-Regulated Bags" and "Ineligible Bags." Similarly, data reported in Table 2 as Other Plastic Material is further broken down here as "Film and Shrink Wrap" and "Other Plastic Material."

  • Regulated Bags: Plastic carryout bags that bear the “PLEASE RETURN TO A PARTICIPATING STORE FOR RECYCLING” notice.
  • Non-Regulated Bags: Plastic carryout bags that do not bear the “PLEASE RETURN TO A PARTICIPATING STORE FOR RECYCLING” notice.
  • Ineligible Bags: Unregulated or mislabeled plastic bags (e.g. plastic trash bags, shopping/merchandise bags, sandwich bags, zipper bags, produce bags, etc.).
  • Film and Shrink Wrap: Plastic agricultural film, drop cloths, stretch and shrink wrap used to transport merchandise, packaging, other plastic wrap.
  • Other Plastic Material: Durable plastic items such as, but not limited to, bottles, hangers, tubs, and pails.

The results show that in 2007, of the 5,494 tons reported as collected for recycling using the commingled method, only 325 tons of regulated plastic carryout bags were collected.
