Are strings garbage collected?

What happens useful materials in garbage?

• lets say i throw my recycling into my garbage then i put it in a bag and throw it in the garbage container. now when the truck comes and picks it up will the city waste collect it in their industry? if so.. do we really need to recycle? it is said that more than 85% of the recycling is not collected... if so then all these recycling goes to the waste plants and will some one pick them out? if so again the question about recycling does not count. so my Q are: what happens to the useful materials we "did not" recycle and were put in the garbage? and do we really need to recycle? and why? thanks you =)

• Answer:

  Anything thrown out in your garbage is disposed of en masse; no one goes through it to pick out useful materials. Depending on where you live, your garbage may go to a trash-to-energy plant, or it may simply be dumped into a landfill. Depending on the type of trash-to-energy plant, some simply "mass burn"; there is no separation of materials, it all goes into the hopper. The remainder at the end of the process is dumped into the landfill, but takes up a lot less space than unburned garbage. Others create "refuse derived fuel" from the trash, using a mechanical process to separate out certain materials, which are then sent to recyclers; the remainder is shredded and burned, and has a higher combustion rate than non-screened trash. The residue at the end of this process is also dumped into a landfill, but there's a lot less of it than there is with the mass burn method.
