In preparation for reclaiming and recycling the material of construction of a plastic bottle, the friction-fitting base, if any, and bottle cap can be separated from the bottle body by cutting through the cap and base. The cap and base are cut in a plane in which the bottle's longitudinal axis lies. Alternatively, two cuts are made in parallel planes that are also parallel to the bottle's longitudinal axis.
