Abstract
Ways of applying microwaves to feedstock to be processed are disclosed. One embodiment relates to heating inter-layer water in vermiculite to expand the vermiculite. Another embodiment relates to heating water in oil-contaminated materials and waste products, such as drilling cuttings, contaminated soils and certain types of animal by-products, to drive out oil. In some embodiments a microwave tunnel applicator has the microwaves applied from beneath the feedstock.
