Why don't we sell laundry sheets or pods? I know they're convenient, but the binding agent, PVA or polyvinyl alcohol, is a synthetic polymer. It is essentially a soluble plastic that seems to partially biodegrade, but mostly just passes through our wastewater treatment systems as dissolved plastic.
This means that every year thousands of tons of dissolved plastic enters our water, sewage sludge, and soil as a result of these sheets and pods. We don't know yet what the long-term health and environmental impact of PVA is, but we know that it is contributing to plastic waste, we just can't see it - which sounds very concerning to me.
Here is some info from Made Safe.org
I know it's less convenient, but please consider using powder or liquid detergent.
In store, we have closed-loop refill options for both powder and concentrated liquid so there's no plastic waste - come try some!
