Abstract
Degradation of body-waste bags to assist disposal thereof in sewage systems is facilitated by addition of a base to raise the pH of the human fecal waste bag contents to at least about 12. Inter alia, there is provided a package of at least one bag and sufficient base, preferably in prepacked quantities, to treat all the bags in the package.
Claims10
A package including at least one body-waste bag comprising a 3-hydroxybutyrate polymer and requisite amount of a basic material to modify the pH of the contents of all the body-waste bags in the package, at the time the bags are half filled with human faeces and/or urine, to a value of at least about 12.
A package including at least one body-waste bag comprising a 3-hydroxybutyrate polymer and a basic material selected from sodium hydroxide and sodium carbonate monohydrate, the quantity of base in the package being at least 0.2 xn of sodium hydroxide or at least 5 xn g of sodium carbonate monohydrate, where n is the number of said body-waste bags in the package and each body-waste bag has a total capacity of 100 .times.ml.
A method of disposal of a body-waste bag comprising a 3-hydroxybutyrate polymer and containing human faeces and/or urine including the steps of modifying the pH of the contents of the bag to a pH of at least about 12, and thereafter introducing said bag and contents into a sewage system.
