despite its stigma, plastic is the lowest impact material and the best option for us. here's why: first, we've found that sourcing glass results in a 40x higher impact than PCR plastic.* the next material we looked at is virgin aluminum, which has a high impact dues to its mining + refining process. lastly, we can't source recycled material with an unstable supply making it difficult to use recycled aluminum. we know that glass and aluminum have high recyclability rates, but when looking at the entire supply chain as a whole, we couldn't justify switching to tighter impact materials. *calculated using sustainableminds software.
