Key Strategic Challenges
Waste infrastructure
• Landfill capacity
• Possible capacity issue arising through 2020s
• Dependent on delivery of other residual waste infrastructure
Environmental Services Association
Chairman, Stewart Davies, writing in the
July 2017 edition of the CIWM Journal
Key Strategic Challenges
BREXIT
• RDF export – increasing costs due to currency exchange rate changes
• Will recyclate quality be an issue for importing to EU? Especially in
relation to recyclate from co-mingled sources
Key Strategic Challenges
Global Issues
• China recyclate import restrictions – the need to find alternative
markets and improve the quality of recyclates
Key Strategic Challenges
Waste Crime
• Consequences of failing to prepare and adapt to other challenges
• Need to reduce access to waste, especially materials for disposal,
recovery and low grade recyclate
Key Strategic Challenges
So what?
• Risks arising from these challenges can be mitigated by:
• Increasing waste prevention, reuse and recycling – reduce
amount of waste for landfill
• Increasing the quality of recycling – better quality = higher
value: less likely to be illegally dumped; increased supply of
materials to the local economy; and more likely to have broader
market access
• Local integrated waste infrastructure, including residual waste
infrastructure – makes Northern Ireland more resilient to
volatility in global commodity markets and external actor

HHWRC improvement scenarios
Positive low cost gains achieved from improving facilities at
HHWRCs (1) and policies to improve separation (2)
1. Possible to meet 50% from kerbside scenarios
2. Possible to meet 50% in 2020 (just) assuming all NI LAs start in 2018/19
3. The groups of scenarios which meet 50% all include either 3 weekly residual or restricted
residual bin volume
4. 3 weekly residual scenarios are consistently lower cost than restricted volume
5. Least cost scenarios all include multi-stream (savings coming from co-collection of
separate food waste with dry recyclables)
6. Separate weekly food waste collections increase the recycling rate by over 6% compared
to 2% from mixed garden and food waste
7. HHWRC scenarios add over 3% and would support kerbside scenarios to increases
beyond 50%
8. Scenarios including flats, adding in missing dry materials at kerbside, communication
campaigns add minimal increase to the recycling rate
9. However, communications and associated implementation resources are considered
essential in transition to achieve the performance detailed in scenarios
