Our Commitment to Transparency in Sustainability Calculations

At LUCYA, we prioritize transparency when it comes to our sustainability efforts and the methods behind our calculations. On this page, we provide an in-depth insight into the intricate calculations that support our sustainability claims.

**Total Plastic Bottles Transformed**

Have you ever wondered how we arrived at the figure of 1,823,783.78 single-use plastic bottles transformed into our signature thread? Here's how we calculated it:

As of August 31, 2023, LUCYA has acquired 16,870 kilograms of yarn, all of which is derived from 100% post-consumer recycled plastic bottles, certified by the SCS Recycled Content certification.

To determine the total number of bottles transformed, we employ a standard representation: a 16.9-ounce bottle weighing 9.25 grams. We have chosen this representation based on the average weight of water bottles in 2014, as reported by the Beverage Marketing Corp. Given the lack of a universal standard for bottle weight due to variations among brands and markets, we use this representative bottle weight to account for such disparities.

However, it's important to note that in the recycling process, some material is inevitably lost due to factors such as color variations and quality. This material loss implies that the actual total number of bottles collected to manufacture 16,870 kilograms of yarn could be greater than the calculated 1,823,783.78 bottles.

16,870 kilograms = 16,870,000 grams / 9.25 grams of plastic per bottle = 1,823.783.78 bottles

**Total Ocean-Bound Marine Plastic**

Curious about the process behind calculating that 37,191 pounds of ocean-bound marine plastic have been repurposed into the thread used in our bags and accessories? Here's the breakdown:

As of August 31, 2023, LUCYA has procured 16,870 kilograms (equivalent to 37,191 pounds) of ocean-bound marine plastic yarn. This yarn is certified under OceanCycle, confirming that the plastic was collected within a 30-mile proximity to the coastline.

Yet, similar to the previous calculation, the recycling process involves some material loss due to factors like color variations and quality. Consequently, the actual quantity of ocean-bound marine plastic collected to produce 16,870 kilograms of ocean-bound marine plastic yarn may exceed the calculated 37,191 pounds.

**Total Plastic Bottles per Shoe**

Have you ever wondered how many plastic bottles are used to craft each type of shoe? Here's our approach:

To determine the number of plastic bottles needed to knit each shoe type, we rely on the weight of rPET yarn used in the upper for the standard sample size of that shoe style, whether it's women's, men's, or kids'.

Our representative for this calculation is a 16.9-ounce bottle weighing 9.25 grams – the average weight of a water bottle in 2014 according to Beverage Marketing Corp. Given the variability in bottle weights across brands and markets, we select this representative weight to account for these differences.

For example, if we consider the rPET knit used for the upper of The Point in women's size 7, which weighs 106.3 grams, the calculation is as follows:

106.3 grams of rPET knit in the upper / 9.25 grams of plastic per bottle = 11.4 bottles.

At LUCYA, we are fully committed to providing transparency regarding our sustainability initiatives, ensuring that you have a comprehensive understanding of how our numbers are determined. This commitment to transparency is at the heart of our mission to pave the way for a more sustainable future.
