What Size Skip Bin Do I Need?

News > What Size Skip Bin Do I Need?

So being use to answering the question that we often get; "What Size Skip Bin Do I Need?" here are some tips to help.

  1. Phone Bins Skip Waste and Recycling up and ask the question and we will do our best to help you.
  2. Try and think about the waste you have in terms that you are familiar with.

    A cubic meter is just like a cardboard box that is 1m tall by 1m wide and 1m deep.  So how many cardboard boxes of that size do you think you will fill?  Other measures that we have found people to be familiar with are trailers and wheelie bins.

    The standard 6 foot by 4 foot trailer seems to a be a measure that many women and most men can picture. So how many trailer do you think you will fill?  By coincidence a 6x4 trailer loaded level with the top of the trailer is about 1 cubic meter in volume.  So if you know how many trailer loads you have, that is the number of cubic meters your bin will need to be.

    Six 320 litre wheelie bins is about 2 cubic metersThe measure we find most women are familiar with is the wheelie bin.  Now the only thing to be careful with here is that wheelie bins come in different sizes.  The 2 most popular sizes are the 330 litre bin and the 250 litre wheelie bin.  For every three 330 litre wheelie bins you will need a cubic meter of skip bin. So a 2 cubic meter bin is the same as six 330 litre wheelie bins of waste. Similarly, it would take four 250 litre wheelie bins of rubbish to fill a cubic meter.  So the 2 cubic meter bin would hold the same as eight 250 litre wheelie bins.
  3. Some times it easier to measure the pile of rubbish.  This maybe because you have a pile of rubbish, or you are going to dig out some soil you want to get rid of, or it might just be you have a pile of rubbish on the front lawn that your wife has threatened you over.  The basic measurements you need are the height the depth and the width of the rubbish pile.

    In the case of the concrete slab you are breaking up you just need the area of the slab (length time width) and the depth. So for the slab from the old shed it might be 3.5m by 2 meters (7.0 meter square) multiplied by the thickness of the concrete 125mm (or 0.125M). Total solid volume is 0.875 cubic meters.  When you break up this solid volume you can easily double the volume needed for it because of the space between the broken pieces of concrete. This could mean you would ant the next size up from 1.75 cubic meters. Yes a 2 cubic meter bin.
  4. Finally lets try the pile of rubbish which is really a sort of cone shape (upside down).  The volume of the cone is as simple as the diagram below:

    Where the number ? is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. r is the radius of the pile or more simple half the average distance from one side of the pile to the other. And last but not least h is the height of the pile of rubbish.
    What a Load of Rubbish
    What a Load of Rubbish

    So if the pile is 1.5m high and 5m across.  h would be 1.5, r is 2.5. So the volume needed is 

    ( 3.14159 x 2.5 x 2.5 x 1.5 ) / 3  = 9.81 Cubic meters

Confused? Just give us a phone call and we'll help you work it out.
