First thing you need to know is that it is not called a dumpster- it is a "roll off container". A dumpster is what you see behind your favorite restaurant (basically a large trash can). A roll off container comes on a flat bed truck and gets "rolled off" onto the construction site to be filled with construction debris. (I remember the day the laborer had to shovel deep snow away from the spot where the roll-off container was to be deposited. Shoveling snow seems so long ago, now that spring has arrived - hooray!)
The next thing you need to know is that this debris is not going to a landfill (like the trash behind the restaurant is). Once full, this container will be picked up and brought back to the recycling center it is rented from. This one comes from 'Recycle Depot' in Poughkeepsie, NY.
You can check out their website to learn about their state-of-the-art facility where almost 100% of the material they receive is recycled into new, useful material - like topsoil and mulch - as well as returning raw material, like cardboard, metal, and plastic, back into the manufacturing process as post consumer product that can be re-used.
Get educated and know where your cast-off items end up! There is no such thing as throwing things "away". Happy Earth Day, everyone!
