Everyone says “just have a clear-out” like it’s a quick job. But if you don’t want to chuck everything in landfill, it’s a whole logistical exercise:
Electrical items have to be recycled.
Dead batteries need to be recycled.
Charity shops are harder and harder to park near. My local charity shops are closing down and others will only take certain items.
My local homeless charity that are kitting out temporary homes will not take new bedding. Only cash.
Some places won’t take certain clothes, toys or household items.
So you end up with piles of “good” stuff sitting around while you work out where it can actually go.
