Abstract: A barbecue in the form of a box that is closed except at the top. Burning material and ash from the burning material is contained completely within the barbecue to protect the environment. Plates rest on a ledge at the top of the box and are slidable to regulate air flow. A lid or lids close the firebox to avoid spreading dust during transport. The base and walls of the firebox may be filled with insulating material. The firebox may be configured as a barbecue, an open fire or a rotisserie.
