Landfills really aren't that bad. modern landfills have multiple layers of lining to prevent leaking into water supplies and soil. After they are full, they are covered with earth and can become usable land. Their gases have to be managed (can be burned for electricity or processed in other ways) but overall putting trash in the ground and covering it seems alright to me. The amount of land that you actually need isn't that much too.
