Amazingly, but you can produce a lot of useful from your trash. For example, solar concentrator.
It can be done easily. To do this, cut the edges of an aluminum can. These cans are produced everywhere for a beer or juice conservation. Cut the piece without edges to get some straight sheet of aluminum. Wash away all dirt from both sides of aluminum sheet. So, you'll receive shiny piece of aluminum sheet of rectangular form.
Now, attach several equal pieces together in one long and straight sheet, which should be curved to form a parabolic solar concentrator trough. And that's it! Your parabolic concentrator is done. If it's placed properly than it's able to concentrate the sunlight about 10 times.
