I googled global waste per year. Looks like it's on the order of 2 billion tons per year. Leaving room for 100% growth, and assuming a density of 1 (less dense = more space required = worse), we'll need 4 billion cubic meters of landfill per year.
That's a cubic mile of garbage!
But that doesn't seem all that catastrophic either - if you spread it out to a hole 1m deep, it'll be 63 km on a side. 5m deep = 28km on a side. That's a lot, but it doesn't seem like the highest ecological priority. If it's practical to compress before dumping, it will be even less terrible.
