Our wins have mostly been in the kitchen so far:
we invested in glass Tupperware, reusable silicone storage bags and silicone jar 'hats' for the kitchen, and have all but eliminated our use of cling film and tin foil. I've also switched from non stick baking sheets to pyrex ones, which never warp and can be scrubbed to death if grim.
Where possible, we buy fruit and veg loose instead of in plastic. We're trying to increase the amount of veggie meals we eat.
I favour buying condiments in glass containers over plastic
Cleaning wise, we've focused on drastically cutting the number of plastic bottles and the number of different products we use. We use diluted zoflora as a surface cleaner. Washing up liquid is a great degreaser. 1 bottle makes up several litres so saves money too.
We stopped buying kitchen roll and now use cloths instead, which get washed and reused.
In the bathroom, I've switched from disposable razors to safety razors which again has helped drastically cut down on plastic. I'm using shampoo bars in rotation with my normal shampoo. Haven't yet found a product that would help me make the switch 100% but it's still less packaging overall. Cotton rounds have been replaced by washable ones. Cotton buds now have paper or bamboo sticks.
At christmas we've drastically reduced our use of gift wrap by investing in reusable fabric gift bags. I'm now looking to build a small stash of ones we can use for birthdays.
My new areas to look out will be further reducing the clothing we buy, and buying less but of better quality. I want to give period pants a whirl. I'm also trying to invest in better quality shoes, which I can then get resoled as needed instead of simply thrown away. I also want to find something to replace our current choice of washing up sponges, which never seem to last especially long.
