And emission CO² level what gives what? It may be better to burn wood that will emit CO² absorbed by the growth of other trees rather than transformed cardboard that will eventually emit more CO² once burned no?

I understood this on other forum but maybe I misunderstood.


It depends on the point of view ... That is to say what you count or not ...

I did not want to mix CO2 and Primary Energy in this subject but I see that it is too late.

My reasoning is as follows: the cardboard will, indirectly, emit more CO2 than the same tree if it had been burned because it will be necessary to take into account the different processing and transport.

BUT (because there is one but obviously): this cardboard is WASTE ... its primary function was not to be burned! Burning it will therefore avoid burning another tree (or worse, fuel oil or coal). And this is where it can become interesting in terms of the CO2 balance ... especially taking the indirect CO2 costs of recycling.

In addition, we can do exactly the same reasoning on recycling between CO2 and primary energy:

Spend 2 L of gasoline to bring cardboard to the waste disposal whose recycling will ultimately deduct from saving 0.2L is a nonsense!


By replacing "L of gasoline" by "kg of CO2 ..."

Suddenly, I fear that a good part of the cartons and other papers collected will end up ... in the incinerator.


Well in this case I prefer to incinerate it at home and save kWh EP rather than greasing the system of incinerators!

It is not Jonule who will contradict me on this one! : Cheesy:

Recycled paper is actually more expensive than normal paper. I had a teacher who only used that to distribute his lessons (a little green side I guess), his lessons were more expensive by the sheet than those of other teachers. He told us the price difference at the time, but I don't have it in mind at all.

It costs more in stores ... it does not mean that it comes more expensive from the factory ... or rather that it costs more to be manufactured ...

You know that anything green tends to be overcharged ... (except on the eco-friendly shop of course : Cheesy: )

Speaking of shop, for the edition of invoices we pay the same price for recycled as the normal "mid-range" ...

In my opinion, as in all fields, there are competent people and charlatans. There are honest people and scammers everywhere.
By that I mean that certain ways of recycling paper are not really beneficial for the environment!

The ideal, in my opinion, to improve the efficiency of recycling would be to carry out a sorting as is done with glasses and plastics.
It also seems to me that quality paper should probably be easier to recycle.

: Arrow: I think that if you burn good quality paper or cardboard, that is to say without all the junk that the inventory was made above, it is a PERFECTLY ECONOLOGICAL choice. 8)

I already considered the question and broached the subject on the forum.

For this it is necessary to have a high-efficiency boiler.
I was planning to make my own pellets from all the paper and cardboard that I usually put in my recycling bin. In the end, the idea is to recycle the waste yourself, which increases my household waste taxes each year so that others recycle it ... : Evil:

I'm for 200% : Mrgreen:

Uh the arsonist arrives in the subject, what the professional firefighter brother said does not surprise me at all ...
So let's put ourselves in the place of the late brother, what does he need to live on?
Well, it's very simple, it needs a lot of air and ... It may sound silly, but it needs heat.
The ideal solution seems to me in this situation, it would be to burn the paper after having passed it in a shredder of the style which one uses in the offices to destroy the documents!
The disadvantage obviously is that in this form it takes up a lot of space and that of course the ecological point of view of the energy absorbed by the shredder is to be taken into account ...
So the suggestion is as follows: burning paper or cardboard in a charcoal stove would probably not be a problem as long as you have one (and since it is not very ecological ...); compact the flakes of paper obtained after crushing to make logs ... It would probably be much less stupid than soaking the paper in water to have to dry it later (whatever I know it works) like the said C moa it's a famous chore!
So all you have to do is experiment Christophe!
I have the impression nevertheless, that it would be much better if the logs looked more like pieces of wood, than with logs-for the reason mentioned above-it takes air, so that brother burning fire …
It seems to me from my experience, that the ideal device for burning them would be a “burn all” in vertical Godin cylindrical style and in this case perhaps, moreover, that the solution would be to make small balls of paper. compressed from shredded paper…

The subject therefore remains open, whoever finds the solution will surely bring some energy and warmth to others.
With greetings from Lietseu :P

This is what we did almost 40 years ago ( : Shock: damn time goes by) in my grandfather's charcoal stove, with corrugated cardboard rolled into a log. :D

Me, I heated myself with wood in my old house, at 12 I understood it much better than I knew my Father!

For years we used an Ardennes-style stove made of rectangular parallelepiped sheet placed one on top of the other, the one above used as a recuperator, the machine was great, I dream of making one before I die ... it heated the whole little house of my old people! And with what warmth, of the one who captivates you and drives you to dream ... ah, looked at the snow-white garden through the layer of ice in the morning, of frost in the evening, which covered the inside of the windows of the room ate!

These are good memories, the hissing of chestnuts, which exploded if by chance we forgot to make a slit in the fleshy part ...

At the time the collection of wood in the Forest of Soigne was still tolerated, the chore wood to split the "feet of elephants" was a job that warmed him!
Finally ! All that to say that wood is the foot!

I regret that I no longer have the possibility of making a fire, the better I miss it.

As for unmarked cardboard, I think it's fairly easy to recycle.
By cons for the rest, it certainly takes significant quantities to financially justify the investment. If huge quantity, it means km therefore suddenly, ecologically it is probably not very good.
When burning paper with colors, I add to what is written that there are often metal oxides in colors and other products if it is laminating, glazing. It is probably harmful to burn them without a filter.
Have you asked yourself the question of how much of the sorted waste collection containers was recycled?
In my opinion not very important because every time I look into it, there is almost anything. The worst I have seen is in Corsica.

paper buchettes it seems a good solution .. we can also make sawdust bricks / filtered oil residues (for connoisseurs).

I say that because this waste, well mine, I bought it and it belongs to me! so it's raw material, there are watts in it and they are for me ;-)
it's always that saved, there are no small ones.

on the other hand for the chlorine of the paper (green flame): does it burn completely or is it better to stay at home locked up?

otherwise I hear about filters: do you know any for the individual?
