After efficiently burning your debris with an air curtain burner, you will be left with ash. Some people will bring their ash to a local dump. That requires finding one within a reasonable distance that doesn’t have a high dump fee, which would eat into your pocket. So how much ash will be left over after you use an air curtain destructor and what is a better use for it?

How much ash is left after burning?

After using an air curtain incinerator to burn your debris, the amount of ash left over is normally equivalent to 2-5% of your original debris volume and can oftentimes be covered over or spread out on the property. However, there are actually other practical uses for ash that could be of real benefit to you.

What can you use ash for?

Their goal is to prevent this nutrient rich material from being landfilled and to use it in an effective way.

Another effective and beneficial way to utilize wood ash is to add it to cement. The addition of ash has been found to be a promising method of increasing the strength and thermal insulation of cement blocks.
