Abstract: This disclosure describes, in part, methods of making compost by combining shellfish waste and fruit waste. In some implementations, the shellfish waste contains chitin and calcium carbonates and the addition of the fruit waste may provide a deodorizing function as well as a de-carbonization reaction to the shellfish waste. In other implementations, where chitin may not be present the shellfish waste, the addition of the fruit waste may produce useful calcium salts and/or the calcium content. In some implementations, the methods may allow for production of compost that is odorless.

Abstract: A process for purifying a substantially unoriented polymer containing an impurity by means of ultrasonic leaching or extraction is described. The process involves contacting a substantially unoriented polymer containing an impurity with a cavitatable liquid, subjecting the substantially unoriented polymer containing an impurity in contact with a cavitatable liquid to ultrasonic radiation at a frequency and intensity sufficient to extract the impurity from the substantially unoriented polymer to form a purified substantially unoriented polymer, and then separating the purified substantially unoriented polymer from the cavitatable liquid containing the extracted impurity. A purified substantially unoriented polymer prepared by such a method is also described.
