Beehive burner

Sawdust and wood scraps are delivered to an opening near the top of the cone by means of a conveyor belt or Archimedes' screw, where they fall onto the fire near the center of the structure.

Teepee or beehive burners are used to dispose of waste wood in logging yards and sawdust from sawmills by incineration.

As a result, they produce a large quantity of smoke and ash, which is vented directly into the atmosphere without filtering, contributing to poor air quality.

There are a few derelict beehive burners remaining in California, Oregon, Washington State and Western Canada.

[2] The majority of wood waste is now recycled and used as a component in various forest products, such as pellet fuel, particle board and mulch.
