Abstract
It is estimated that New Zealand produces about 3200 t/day of refuse from the eight main centres. If it is assumed that the composition of this is intermediate between that of the US and the UK, then a calorific value of approximately 11.6 GJ/t is obtained, which indicates a potential of 37 TJ/day of energy is theoretically available from wastes. Some of the possible processes that could be used, and the yield of either energy or fuel that could be obtained from the assumed raw material are illustrated. It must be emphasized that before much further progress can be achieved in this area, a better knowledge of the amounts and composition of our refuse is necessary. This data is considered as an indication of the potential. The remainder of this paper consists of a preliminary economic assessment of processes that are in a reasonable state of development, i.e. to the stage where a demonstration plant would be built, or better. The currency used is the $US, 1975. Capital is considered to be amortized at 6% over 20 years. Labor has been estimated at an average of $7000. Land and site development is not included as this will vary immensely. However,
