ready I am sharing parental leave with DH and that's a really interesting strategy. Mixed feeding never occurred to me.
I should add to my previous post as I get not everyone wants to read through the whole analysis. In the baseline, disposables are actually marginally better environmentally than reusable nappies. There are really 2 big ways to make reusable nappies more environmentally friendly than disposables (and how many kids use them isn't one of the significant points as reuse (though not 100 percent) is assumed in the baseline)
- Never tumble drying (even in winter)
- Not using a very hot wash setting
Without those, it's difficult to overcome the embedded energy use in laundering after each use. Also poop not thrown away but flushed down the toilet or rinsed away in the wash has to be treated like all raw sewage which also has an additional energy cost relative to disposables. On top of that there is the additional water use.
If you exclusively tumble dry OR use a hot wash above 60c, disposables significantly outperform reusable cloth nappies. Also, if waste treatment in your area includes technologies such as waste conversion to biogas then again disposables pull ahead.
I live in Southwark (in London) which has one of the most advanced waste treatment facilities in Europe. They convert waste to energy. That combined with the fact that as a household we tumble dry the majority of the time except items that can't be dried that way which go on airers means we'd actually be harming the environment by using reusables.
The only way to know if it's an environmentally friendly choice for you is to consider how you'll launder (in the baseline they assume a combination of line and tumble drying rather than exclusively one way or another) and looking into how waste is treated in your area. I'm very lucky to live in Southwark where waste is managed in such a sophisticated way.
