At this price of 15cts of euro of electricity per ton, we all want to go there its vegetable waste of gardens lying around everywhere free or even burned in pure loss !!
We hope that the price of pellets will drop !!

Is there a simplified individual version less than around 30m² on the ground for 4 to 5 tonnes per year instead of 1500 to 500 tonnes per year ???????????,

Producing a ton of pellets from woodwork chips requires less than 15cts of euro of electricity! Thanks to this technology, local production of pellets is now much more profitable than industrial production. We could heat 30 million homes in Europe just with wood that is not valued!

Yes, many of us dream of it, but it will not be at the same price ...

What I expect is a line for 3 to 4 tonnes of pellets / year maximum (you have to find the raw material). This mass of pellets represents 15.000 to 20.000 kWh (i.e. my annual gas consumption for a 110m² pavilion in 1975).

The ideal line that I imagine should not consume more than 7500W or 32A in 230V single phase, but I would prefer that it is rather in a maximum consumption of 3600W or 16A (the power of a dryer).
Congestion issue, I would see it on a footprint and a height of 2 washing machines (and at most less than 2,5m high) ...
With these characteristics, and a VERY studied price (5000 € HT max), this kind of product would have outlets for the general public.
One can even imagine using it in heat cogeneration by injecting into the habitat the calories produced by exceeding it during its operation.
That's a job for some enterprising development or industrial engineers. :P

What would be interesting is to form cooperatives at the local level to buy and operate such a palletizer. The members of the cooperative would bring their plant waste there as at the time of the mill present in each corner of the countryside.

One could imagine replacing a part of the recycling center sector which usually takes care of these types of waste and thus shorten the recovery cycle of this waste.

Very good suggestion, in particular, with the municipalities and regions that manage recycling centers that we pay with our taxes, without making profitable combustible waste at a price as high as that of a real fuel like pellets !!
At the level of a residence with more than 100 pavilions, it is profitable (500 tonnes per year) !!!
Huge savings in money and CO2 !!

Hello,
do you know if the cost includes the salary of the person who operates the machine?

Could we have a little detail of the calculations that give this breakeven point?

bjr to you,

would this process be valid for lawn mowing waste?
there it would be really useful,

Mowing waste is 95% of the fleet. Look at the hay that remains once dried (and it's still about 20% humidity!).

After drying in the summer sun possible, some even make pellets with leaves (simple summer solar dryers, collector plus chimney) !!
The 30m2 machine (one room) produces 500 to 1500 tonnes of pellets per year and therefore can supply more than 100 pavilions at 5 tonnes and more per year !!
She makes 0,2 tonnes per hour at a salary of 20 € or more per hour, unless everyone makes their pellets !!
So on pellets at 200 to 300 € in trade, the tonne there are 5 hours of salary and 15cts of euro of electricity per tonne for free size waste !!!
With a gardener doing other heavy work, or several machines in parallel, also at the same time, the price may be lower.
