Money received in payment for the services of inmate labor employed in the industries carried on at any state correctional facility under the control of the commissioner of corrections is appropriated to the commissioner of corrections to be added to the revolving funds of these facilities. The commissioner of corrections may set aside a portion of the revolving fund of any correctional facility to be used as a diversified labor account for the introduction and encouragement of industries that in the commissioner’s judgment may be beneficial to the inmates of the facilities.
