Abstract

AS/NZS 1546.2 aims to: 1. Provide a set of performance statements that form a base against which any waterless composting toilet, conventional or innovative, may be assessed. 2. Provide manufacturers of waterless composting toilets with a performance evaluation test that will confirm the conditions under which it will function best (this will enable certification bodies to check that a product conforms to the Standard). 3. Ensure that the operation and maintenance of a waterless composting toilet is done in a safe manner that meets basic health requirements given that it involves the removal of composted or partially composted material.
