Yes, you can.
The first requirement would be a steady supply of feedstock needed for the reactor. Not all reactors can handle all feedstocks - the main issue being that the reactor must be able to distribute heat to the feedstock particles evenly and consistently.
The second requirement would be sufficient financing, not only to purchase the reactor itself, but to operate it. More sophisticated reactors that also generate wood vinegar and energy (to produce electricity for instance, or heat for manufacturing) have a much better potential to be financially viable, but they require a much higher level of initial capital investment than a simple batch kiln. The lower capital investment of a simple batch kiln comes at the price of higher labor cost (per tonne of char produced, for instance) and limited outputs (of biochar alone, for instance). Over the lifetime of a project, labor is likely to be the highest cost, followed by the cost of obtaining and preparing feedstock. Hence successful biochar plants will tend to be located as close to the feedstock stream as possible - next to a sawmill for instance, and will invest upfront in labor saving pyrolysis plants and auxiliary equipment.
