Caprolacton waste is hard to handle from my experience. With caprolacton waste, it is important to keep it hot to keep it molten. Also, the fluids should be kept moving to prevent any localized solidification. Recycle lines should be provided back from any isolation points back to the source tanks. Steam should be used for waste atomization to keep the waste hot in the injector. Also, waste atomization injector used should not have restrictions to keep the fluid flowing. In theory, solid waste can be combined with liquid waste and burned together. In reality, it would be difficult to combine them and keep them operating at a high efficiency. My suggestion would be to keep them separate if possible. Heat recovery may be possible depending on economics.
