Global MSW to double by 2025

Edie news reports that the Worldwatch Institute is predicting (with horror) that MSW will double by 2025.

I must confess that I haven't read the original report, but from the article I am unable to conclude whether this is terrible or not.

Waste is not produced as an end in itself. Like other forms of pollution, it is a by-product of useful economic activity. If the benefits of that economic activity outweigh the costs, including those of managing the associated waste appropriately, then on balance the state of the world has improved.

I cannot infer from the article whether the benefits of higher economic output outweigh the costs of higher MSW generation.
