The average American produces 3.5 pounds of trash per day at an average one third of a gram per cubic centimeter. Assuming that holds steady, and we use a normal landfill depth of 400 feet, and the US population doubles over the next century, we need a landfill area of 250 square miles to cover us for the next hundred years.
Compared to available land that's tiny.
- 1589g of trash per day!
- 4767 cm3 to store it (3cm3/gram)
- 130 m3 per lifetime (75yr)
- 300,000,000 lifetimes.
- 78 km3 storage allocated
- 39 km3 required
~~We're gonna need a bigger boat.~~
Neat!
I think something went very wrong there!
4767 x 75 x 365 = I get 130,500,000 cm³/person/lifetime. You got 130,000,000,000,000,000.
There are 10¹⁵ cubic centimetres in a cubic kilometre, not 10⁶. I think all your numbers are for m³, not km³, a factor of a billion out, so your final figure should be 39 km³.
Just because you can’t see it, just because it doesn’t have value to property developers, does not make it junk.
I mean, by this logic, we should just dump our trash in the “junk water” which covers much of the planet.
