Laundry Sheets
There is some controversy about whether laundry sheets are the most environmentally-friendly option for laundry detergent. Below are some points to consider and research on the issue.:
There is some controversy about whether laundry sheets are the most environmentally-friendly option for laundry detergent. Below are some points to consider and research on the issue.:
- Some brands have ingredient lists on the packaging, others do not
- “made with” is not the same as “made of.”
- Many don’t claim “biodegradable”, though the ones that do, don’t have sources (even on the website, let alone packaging)
- Some detergent sheets include polyvinyl alcohol (PVA)
- Poly-vinyl Alcohol (PVA) – a synthetically derived polymer, the same that encases laundry pods, generally approved by agencies (such as US EPA/FDA), “biodegrades under the right conditions.”
- 2021 MDPI study of wastewater treatment plant emissions via sludge found PVAs to be persistent in the environment. This study was funded by Blueland – a company that sells plastic-free laundry detergent tablets
- Ultimately still lacks real-world monitoring or research in the natural environment
- Many researchers agree that claims for more real-world applications are warranted, though they do not necessarily change their stance that PVA is safe, as has been proven through multiple lab studies over the years

- Pro-laundry sheets:
- Reduced carbon emissions with less packaging, less plastic packaging, and lighter to transport
- Pre-measured and reduces over-usage of detergent
- Biodegradability claims
- Naturally-derived ingredients

- Performance review of laundry sheets highlighted particular poor performance in cold water, which is less energy-intensive and will help prolong the life of clothes
- Preliminary research might suggest that the reduced friction from sheets reduces microplastic shedding from fabrics
- Many include other sulfates and acids
- Production may be located outside the US – longer transportation footprint, and be resource-intensive (though they do not contain as much water in the end product)
