1. Presentation to Parliamentary Portfolio Committee
WASTE TYRE PROCESSING
Presentation to Parliamentary Portfolio Committee
13 March 2018

2. Tyre processing Technologies
Categories of processing technologies
Re-use
Recycling
Recovery

3. Re-use: Playground material
Tyre properties (water proof) are still utilized

4. Re-use: Retainer wall
Tyre properties (longevity, rigidity and stability) are still put to use to solve environmental problems

5. Structure of a tyre

6. What it takes to manufacture tyres
Producing tyres takes a lot of natural and human genius

7. Recycling Shredding Crumbing Pyrolysis
All use energy and require expensive machinery to degrade a product of human and natural ingenuity

8. Start from Markets to Process (not reverse)
Starting with methods and equipment leads to elusive markets and idling investments

9. Crumbing plant layout
Expensive machinery

10. Products from crumbing facilities
The form of crumb affects the market where it could sell

11. Rubberised asphalt
Useful for long-lasting, safe (non-skid) and quiet roads. Roads are not built all the time so where are markets for rubberised asphalt?

12. Recycling (downcycling): Pyrolysis
Reversing tyre manufacturing by brute thermal force is not done with aluminum cans which require no subsidy

13. Pyrolysis technology Little commercial experience worldwide
Most plants are demonstration scale
Different types
Yield different quality products
Attempt to reverse the tire manufacturing process
Capital and energy intensive and low margins

14. Recovery: cement kilns
Up to 50% of production costs for cement kilns are due to thermal energy from coal

15. Challenges for tyre recycling technologies
Capital and energy intensive processes
Very specific market requirements so market research important UPFRONT
Off-take agreements are important otherwise no uptake
Competition from virgin products (price)

16. Waste Tyre Processing – Operations Perspective

17. Waste Bureau Vs Redisa Approach
To ensure continuity, WB contracted with Redisa processors
Both Waste Bureau and Redisa focus on Tyre Derived Fuel (TDF), crumbing, pyrolysis, and re-use industries
In addition, Redisa also delivered waste tyre products for processing in export markets – export processing now only allowed after approval by Minister
Not all Redisa processors contracted with Bureau (e.g. no exports) – despite supplying fewer processors, average local processing volumes have increased

NB:
REDISA Data: Jan – March 2017
Waste Bureau Data: Oct – Dec 2017
Waste Bureau volumes processed exceed those processed by REDISA for the three month periods compared.

20. Current Processing per Waste Hierarchy

21. Challenges with Processing Capacity
Lack of processing capacity creates bottlenecks, resulting in full depots and poor service to collection points (e.g. tyre dealers)
Currently concentrated in certain provinces – high long haul transportation costs in provinces without processing capacity
Plant availability also a challenge – downtime disrupts deliveries to processors, again creating a bottleneck

22. Distribution of Processors

23. Actions to improve Processing Capacity
Current processors encouraged to increase tyre consumption
Talking to non-participating plants of cement companies to start using tyres for fuel
To go out on tender for processing capacity –priorities to including:
Distribution of processing capacity around country (pref at source)
To also prioritise moving up the waste hierarchy
