Are you using a plastic sponge to wash your pots?
It is easier to consider single use plastics as bottles or packaging for food, drinks or toiletries but often the sponge used to wash up is made of plastic too. This sponge will then end up in landfill or being incinerated and all the while it is in use it is shedding microplastics straight down the drain.
The advice to change your sponge every 1-2 weeks would contribute in so many being thrown away each year across the country.
How about looking at more environmentally friendly products that could be reused and then when finished put on your compost heap?
I have a few different products in use in my kitchen sink. I am lucky enough to have a few shops locally where I can buy most of these items but if you don’t have a shop to nearby I will include online links below…
Compostable cloths – which are reusable and washable then can just be placed on the compost heap. https://www.friendlyturtle.com/.../biodegradable-sponge.../
A wooden brush with natural fibers which has replaceable heads. https://www.friendlyturtle.com/wooden.../wooden-dish-brush/
A coconut husk pot scraper – which is actually very effective! LoofCo Washing-Up Scraper - LoofCo - Ethical Superstore
I also crocheted some (not particularly beautiful) reusable cloths using recycled wool such as https://www.lionbrand.com/products/re-up-yarn
