We pour used veg oil into the plastic bottles it comes in (we buy in bulk, so like 3l or 5l containers.)
We then keep it outside in the bin store until we have loads/or other stuff to take to the tip, then we take it there, pour all the oil into the special recycler they have there for cooking oil and recycle the bottles in the plastics.
Easy.
I think we should start re assessing everything we make tbh.
A lot of the modern "advancements" have actually totally fucked up our world, compared to the "old" ways.
Classic example.....Fizzy pop/beer used to come in glass bottles that you could take back down the shop when empty and get money back.
Now it comes in individual plastic bottles that aren't often recycled, end up scattered over the earth, and are not so slowly poisoning our seas and wildlife.
Tampons and towles used to be made from biodegradeable materials, and are now so plasticised that they no longer naturally degrade.
Fruit used to come in brown paper bags, now tightly wrapped in petrol based plastic.
We need to go back to reusable, as opposed to disposable.
And no one needs to wipe with moist anything after the loo, so long as you wipe properly, and bathe regularly, you do not need plastic based wipes that are responsible for killing marine life.
