Do you really think that?
Companies make disposable crap so they can make their profit off of it and then not have to worry about paying for its disposal: let it become somebody else's problem. This is what happens when private companies are allowed to control every aspect of production and distribution in our society without restraint: they take the most profitable path no matter who is harmed in the process.
In accounting, this is called an externality, because the people outside (external to) the company making the mess (and the profits) get to pay for its cleanup. It's the reason we literally have mountains of poisonous plastic (and other) garbage piling up around the planet, and, I might add, one of the many wonderful reasons that those of you under the age of 20 can expect to live to the ripe old age of 40 -- if you're lucky.
So any time someone has a reason to clean up somebody else's garbage (poisonous or otherwise), you should think that it's a good thing -- not a waste of time. -

Yea I was joking. But sorry I made you write all of that.
According to one study, a ton of ore from a gold mine produces just 5 grams (0.18 ounce) of gold on average, whereas a tonne of discarded mobile phones can yield 150 grams (5.3 ounce) or more."To some it's just a mountain of garbage, but for others it's a gold mine," said Nozomu Yamanaka, manager of the Eco-Systems recycling plant.
