I have difficulty keeping humidity levels down in my small, windowless apartment bathroom. Try as I might (and I've tried everything just shy of bleaching, which I don't want to do) I can't seem to keep my shower curtain liner from getting moldy, which has led me to replace it far more often than I would like.
So I recently went on a search for a better liner, and came across this biodegradable shower curtain, which has me intrigued.
The biodegradable shower curtain is one of a handful of products from Sustainable Living Group, a small company based in San Jose, California working to provide "quality and innovative products that have a positive impact on the planet." While I think they mostly provide products directly to companies and communities looking to reduce their environmental impact, they also sell to consumers, and you can order directly from their website.
Their biodegradable shower curtain liner is made of 100% polyethylene that is BPA-free, PLA-free, and latex-free. It's made in the USA and can be composted, recycled, or mixed in with trash. How does it biodegrade? It looks like it's formulated to decompose when microorganisms such as bacteria, algae, and fungi go to work on it. The liner has undergone the following tests to determine its biodegradability:
- ASTM D5209-91 "Standard Test Method for Determining the Aerobic Biodegradation of Plastic Materials in the Presence of Municipal Sewage Sludge"
- ASTM D5338.98 "Standard Test Method for Determining Aerobic Biodegradation of Plastic Materials under Controlled Composting Conditions"
- ISO 14855 method "Evaluation of the Ultimate Aerobic Biodegradability and Disintegration of Plastics under Controlled Composting Conditions"
- ASTM 5511 "Standard Test Method for Determining Anaerobic Biodegradation of Plastic Materials Under High-Solids Anaerobic Digestion Conditions"
I just hung the curtain last night, so I'll report back on its performance!
