Appendix A: Template for Assessing the Regional Suitability of Waste Reprocessing Technologies for Tyres, Plastic and Glass
A template has been formulated to summarise and assess the options available for the reprocessing of tyres, plastic and glas in a given region across New Zealand. The shaded area depicts information on various technologies which applies everywhere in New Zealand. Conversely, the non shaded area (Barriers to Regional Suitability), varies across New Zealand and has to be determined for each study region taking into account factors such as distance to reprocessors, existing regional reprocessing infrastructure, transport costs and volumes, for example.
The template includes information relating to the capital investment required to procure the various technology options and the minimal viable scale needed to operate each facility or process. Where this data has not been available specific information relating to a actual, planned or commissioned plant has been used. The end products of each option are included and whether the technology is under development or available as a proven process applied in New Zealand and / or overseas. An assessment and generic rating system of low, medium and high has been applied to the individual Economic Sensitivities and Risks, with low (white circle) indicating minimal cost or risk, whereas high (black circle) indicates a significant cost or risk. The categories considered under Economic Sensitivities and Risks include:
- Entry Cost - capital or other investment required to establish each process
- Transport Costs - cost of transporting glass to the reprocessor.
- Product Demand - actual demand or potential market for the product
- Feedstock Quality - the degree of colour sorting required for each technology
- Technology Development - small scale trials or widely used proven technology
- Volume Dependent - minimum process throughput required for operation
