Disposal of wood ash and pellets: how to differentiate and manage the ash produced by pellet stoves, fireplaces and thermo-fireplaces.

The cold has arrived! The hearth of thermo-stoves, stoves, fireplaces and thermo-fireplaces can heat the house ... yes, but where to throw the ashes produced? On this page, find out how to recycle the ashes of the wood stove and fireplace as well as properly dispose of these combustion residues.

Disposal of wood ash and pellets

Correct disposal of the ash requires its disposal in the separate collection. Which? That of the staff. The ash from the hearth must be removed and disposed of in the humid (organic residue) of the separate collection or used as fertilizer or raw material to prepare soap at home.

How to dispose of the ash from a pellet stove or fireplace? With the collection of wet.

Remember that removing the ash is not the only maintenance job to be dedicated to thermo stoves, pellet stoves or fireplaces. The flue must be cleaned at least once a year by specialized personnel while soot and various thickenings must be eliminated using a dry brush.

In appliances with automatic cleaning systems, maintenance work is reduced to a minimum but this is not always the case. For cleaning the pellet stove, there are specific products on the market that eliminate dirt and soot.

Among the various products on the market we point out"Soot stop"which facilitates the cleaning of the glass of stoves and fireplaces, eliminates soot from every surface. The product is offered on Amazon at a price of 11 euros with free shipping.

How to recycle the ash

It's possiblereuse the ashesof the hearth of pellet stoves or fireplace for the production of homemade soap or to fertilize fields and vegetable garden. In this paragraph we will see how to recycle the ash produced by the combustion of pellets or firewood.

Fertilize the garden with ash

Ash is an excellent fertilizer for the vegetable garden. Attention, it is possible to fertilize with ash only if you only insert wood or pellets in the firebox! Ash with residues of other waste is no longer suitable for fertilizing fields.

If the combustion is complete and clean, from a quintal of wood you will obtain 2 - 3 kg of ash to be used as fertilizer. The ash can be sprinkled on the fields to be cultivated: it contains boron, copper, zinc and manganese. The nitrogen from the wood is lost with combustion, but a good amount of phosphorus remains in the ash (about 3.5%) and higher levels of calcium and potassium.

Overall, the ash is a decent fertilizer with medium release: in the first year it uses up about 80% of its potential.

The ash is not without its contraidications: being rich in calcium, it is not suitable for the fertilization of acidophilic plants. For acidophilic plants, only pine wood ash (low in calcium) can be used.

How to make soap with recycled ash

Another way to recycle the ash from pellets and firewood is to produce homemade soap. The ash, in fact, is the basic ingredient for the production of the lye.

Lye, popularly known as lye, is a liquid obtained from the process of "ash leaching " and used as a base for the production of soap.

We told you that ash is rich in potassium, this element is contained in the ash in the form of carbonate and hydroxide. Potassium carbonate and potassium hydroxide are essential for the production of homemade soap.

The first step of leaching can be done in a plastic container (in a bucket). You must be careful to mix the mixtureat leasta couple of times a day. Know that waiting times are directly proportional to thecausticityof the product obtained: the longer it is left, the more caustic the lye is.
