Selective sorting: evolution of the weight of the waste since 2004

[Christophe]

Following this topic https://www.econologie.com/forums/tri-select ... t6547.html and the measurements and surveys carried out by A2E since 2004, I was able to draw some very interesting curves on household waste. A2E correct me if I say stupidity.

A) These are monthly statements of the weight of waste classified by type of waste according to this classification:

- Plastics
- Cardboard newspapers
- Glasses
- Metals
- Composting
- WEEE
- Homemade incineration
- Publicity
- Other waste

B) It concerns a family of 3 adults on average.

C) Surveys carried out between October 2004 and October 2008, ie over 4 complete years.

For each curve I drew the linear curve (= right) of correlation. The coefficient before the x gives the increase (if positive coefficient) or the decrease (if negative coefficient) per month of the volume of waste. Example for plastics (pink) we have a coef. 0.06. This means that between 2004 and 2008, on average, there was an additional 60 grams of plastic waste per month.

Or an increase of 60 * 12 * 4 = 2.8 kg / month over 4 years ...

D) The A2E hearth is however particularly clean because the average waste per French person is 360 kg / year. The A2E outbreak is at 530 kg / year over the 4 years, ie 530/3 = 177 kg / inhabitant.year 51% less than the national average, including composting!

E) The WEEE peak in July 2008 corresponds to the change of: 1 washing machine + 1 tv + 1 PC monitor (would you have taken lightning A2E?)

Let's go!

I) volume per year:

And here are the evolution curves, waste by waste with the same color code as the previous diagram.

II) Plastic waste



Increase of 60 grams per month or +2.8 kg / month over 4 years.

III) Papers and newspapers



Increase of 30 grams per month or +1.4 kg / month over 4 years.

[Christophe]

IV) Glass



Increase of 10 grams per month or +0.48 kg / month over 4 years.

V) Metals



Reduction of 50 grams per month or - 2.4 kg / month over 4 years.
Probably for the "benefit" of plastics.

[Christophe]

VI) Compostable (and composted) waste



Reduction of 20 grams per month or - 0,96 kg / month over 4 years.

The decrease indicates:
a) less food waste?
b) fewer people at home so cutlery served?

VII) WEEE (Waste equipment, electrical and electronic)



For this curve, I did not draw the trend curve because it is not very significant given the few measurement points and the peak in July 2008 corresponding to the change: from a washing machine, from a TV and a PC monitor.

The "smallest" annual peaks correspond to the end of the year every year, so I guess these are "Christmas gifts" that have replaced old hardware?

[Christophe]

VIII) "house incineration" (A2E will explain in more detail what it is)



IX) Advertisements



Advertising is the strongest growth, 90 grams more per month over 4 years! Over these 4 years we therefore receive 4.32 kg more per month !!

This is typical of today's overconsumption society.

It would be interesting to see the evolution of this with the crisis. A2E continues well STP to make the readings!

The last category "other waste" is not significant enough to draw a curve.

[Christophe]

And here are 2 last curves on the evolution of total waste (not in the right direction despite the so-called "effort of society to reduce waste").



The peak of WEEE in July 2008 somewhat misleads the trend, so I deleted it to put an average value:



Some analyzes:

a) Without surprise the most months grimey are located at the end of the year: November and December. With the peak still in November. Reasons? Excessive advertising, gifts, meals ... On the other hand, if I expected it, I did not think that it would double the monthly volume of waste, from 35kg / month we go to 70 kg / month.

Conversely, January is the "cleanest" month, so much the better it leaves a little respite for the garbage collectors ... and the planet after the euphoria of the end of the year ...

b) The waste trend is "clearly" on the rise and the A2E focus is clearly BELOW the national average. Yet he makes "efforts" (well, what most people call effort, I call that common sense).

Reason? Growth, overconsumption, hypermaketing ...

I can't wait to see how the current "so-called" crisis will affect the volume of waste ... if it doesn't drop, there is NO crisis ...

And a last one for the road:

Nice job Christophe and thank you to A2E for its surveys!

We notice that despite the efforts that we, individuals, can make it is difficult to see our waste "nest egg" decrease.
Perhaps the best would be to return "unjustified" waste to those who produce it ...

Now, it remains to be seen the feasibility of this idea !!!

Easy Greg:
Last year, I collected the envelopes "postage paid by the recipient. (Credit offer, vpc, magazines ...)
One rotten afternoon, I opened the "old paper" box to the children with the instruction "must be consistent".
I tell you not the head of the banker when he saw, religiously cut by my daughter 3 barbies + a bunch of accessories with the mention: would you agree to give me a small credit of 544.89 €? It's for buying that!
Needless to say, all the shipments were more than 50grams, for them to pay a surcharge, of course

Nice work Christophe

Great your idea swift2540

I just found an activity for my little cousins ​​during the Christmas holidays
