How to get rid of useless home items

[dsi11]

Over the past 10 years I have accumulated a lot of stuff that is too broken or used up to be sold, so I want to just get rid of them.
For example, stuff like broken blenders and many kinds of old luggage and an old table.

A few times per year there is the "Siivouspäivä" but I have given all my useful stuff there. This is stuff that nobody would want.

I live in Helsinki city center and don't have a car.

I have sometimes seen this type of mobile dumpster called a "vaihtolava" (http://www.vaihtolava.fi) in my neighbourhood for construction or other reasons and I wonder if it is possible to rent one of these just to get rid of useless items?

And do I need to separate anything that is electric (like an old blender) so that it is properly disposed of?

Or do I just need to use one of the bigger cars/vans from CityCarClub to deliver my junk to the recycling center?

You rent a car or van and take them yourself to https://www.hsy.fi/fi/asukkaalle/lajitt ... fault.aspx
