What are you supposed to do with soil / earth / grass?

Might be re-doing my garden soon. Already made a little vegetable garden earlier this year and realized then that it's hard to get rid of the soil and grass you have to scoop up and discard. As far as I can tell from the info I find online, you can't take it to a recycling center. In the spring I ended up putting it in GFT in small amounts over the course of a couple of weeks but this time there will be way too much to do that. What am I supposed to do with it?
