Options Appraisal

Evaluation approach

• Evaluation framework
• Quantitative analysis – cost, waste flows, performance
• Qualitative – assessment criteria
• Develop Scenarios
• Discussion on framework
• Debate/revise SKM’s initial evaluation

Evaluation framework – qualitative criteria

• Performance
• Diversion from landfill
• Recycling rate
• Cost
• Collection
• Treatment/Disposal
• Implementation
• Compatibility with existing systems
• Perception of stakeholders
• Technical deliverability
• Market risk
• Involves all councils/supports partnership

Option development/modelling

Defined problem and solutions required

• Collect data
• Review of data – establish baseline position
• Defined group of scenarios to help identify solution
• Model variant scenarios
• Built 3 models that work together

– GIS spatial modelling (to understand logistic cost and facility location) – Waste flow (to determine performance and flows) – Basic cost modelling (to determine cost)

Scenario components

Staged approach:

• 1. What happens at collection
• 2. What happens for bulking and transport
• 3. End treatment
• 4. Also consideration of waste prevention

Scenarios Modelled

• Status Quo (benchmark / baseline to compare against)
• Maximise performance of status quo, focus on increased capture of

recyclables kerbside/self haul

• Constrained residual container capacity to drive improvement in

recycling (residual bin 140l)

• Organic waste collection/processing
• Food waste treated through Anaerobic Digestion (AD)
• Garden treated through windrow
• Mixed food and garden treated through In Vessel Composting

Scenarios Modelled (2)

• Biodrying MBT, based on Port Stephens facility
• Waste Prevention – through increased campaigns
• Regional Landfill – fully engineered landfill with gas extraction
• Waste to energy (combined with option 5 mixed food and garden

to comply with EfW policy). Gasification with pre-treatment

Headline Assumptions

• Collection systems

– All options assume that the enhanced baseline position is reached – The baseline and enhanced baseline assumes existing

• rganics collections are in place

– Waste prevention option targets food waste, junk mail, furniture, e-waste

Headline Assumptions

• Bulking and transport - simple bulking arrangement then onward

transport to the treatment facility

• MRF - Existing arrangements
• Organic
• Windrow for garden waste - local facilities for each area
• Anaerobic digestion for food waste - 2 facilities, upper/lower

valley

• In vessel composting for mixed food and garden waste - 1 or

2 facilities considered

Headline Assumptions (cont.)

• Residual Waste Treatment

– bio-drying facilities to reduce volume and remove aggregates and metals >100ktpa for single site, based on Port Stephens AWT facility, – Gasification facility energy produced (requires pre treatment of waste) >250ktpa but sized to waste (located Newcastle area)

• Landfill

– New engineered landfill(s) with gas capture sized to total waste over 20 years (located in Newcastle for 1 regional facility or 1 in Muswellbrook and 1 in Newcastle to serve upper/lower valley).

Headline Assumptions Cost

• Landfill cost $265 / t in 2013 (based on the current landfills)
• Transport cost $ 0.3 / per tonne/KM
• Organic Waste Treatment

– Garden only – windrow at $ 55 / t – Food only – anaerobic digestion based on size ranges from $ 75- 150/ t – Mixed food and garden – in vessel composting at $ 75 / t

• MRF based on existing contract
• MBT $ 176 / t
• Gasification $ 150 / t assuming energy income of @ $ 70 MWh

Outputs

• Used base year of 2021/22
• Mass Flow

– Recycling rate – Landfill diversion

• Cost

– Cost per household ($AUD) – Total cost ($AUD) – Cost is an annualised cost – Combined capex/opex cost

GIS outputs

• Transport outputs fed in to cost models
• Optimisation options for partnership working

– Facility location based on waste distribution between upper and lower valley authorities – based on single end treatment/disposal end point, using existing/planned waste facilities where possible

Outputs

• Used base year of 2021/22

– Cost per household ($AUD) – Total cost ($AUD) – Cost is an annualised cost – Combined capex/opex cost

Summary of Preferred Solution (s)

• Facilitated Discussion
• Relative assessment between solutions
• Priorities of approach and link to strategic framework

Baseline Position

Baseline Position

• 1. Range of data:
• Infrastructure
• Population / households
• Composition
• Performance
• Waste flows
• Cost
• 2. Review of baseline capacity gap

Comparison of current recycling rate with 2021/22 targets

*Does not include C&I recycling for Maitland at 7.5% **If ferrous metals and compost from AWT are recycled - Port Stephens = 58% and Upper Hunter = 90%

EPA Guidance – Baseline Tables

• Collection and recovery systems – Table 18/19
• Waste forecast – Table 22
• Performance analysis – Tables 24/25

Waste Strategy

Strategy – Vision/Themes

Vision The Hunter Region will take a proactive approach to an evolutionary and sustainable waste management system for the Hunter Region, enabling the whole community to improve environment and community well-being by: – reducing the environmental impact of waste – using resources more efficiently.

Themes

Avoidance and Waste Reduction Increased recycling and resource recovery Diversion of waste from landfill Managing Problem Wastes Reducing Litter Reducing Illegal Dumping

Strategy – Themes/Objectives

Avoidance and Waste Reduction To reduce waste generation per capita by 5% by 2021 Promote behaviour and culture change with residents and businesses to help move waste up the hierarchy Increased recycling and resource recovery Achieve a 70% recycling rate for MSW by 2021/22 Achieve/Contribute to the C&I and C&D 70% recycling rates for 2021/22 Implement a data strategy - why Consider the implementation of new schemes to collect organics material and a wider range of recyclables Diversion of waste from landfill Achieve a waste landfill diversion rate of 75% by 2021/22 Actively promote re-use opportunities and consider the development of re- use shops at waste sites Work with local business/industry to support opportunities to develop new markets for recycled products Consider options for the alternative treatment of waste that minimises landfill disposal

Strategy – Themes/Objectives

Managing Problem Wastes Define problem waste areas for the Hunter Region and make sure sufficient data is available for these waste streams. Develop a regional approach for dealing with problem waste Provide facilities for managing problem waste at all/selected regional drop

• ff sites

Reducing Litter Reduce the number of litter items by 40% compared to 2011-2012 levels Actively support state initiatives and programmes on litter reduction and actively spread the message to local communities Gather baseline data on litter incidents to support regional and state initiatives as part of the overall data strategy Reducing Illegal Dumping Reduce the incidence of illegal dumping by 30% compared to 2010/11 levels in line with the state strategy to combat illegal dumping Gather baseline data on illegal dumping to support regional and state initiatives as part of the overall data strategy Support implementation and operation of regional RID Squad Other Embed sustainable resources management principles into Council purchasing and decision making processes so that environmental impacts are always considered

Strategy – Actions

• Problem waste
• Illegal dumping and Litter
• Data Strategy
• Community engagement and communications strategies
• Improving C&I and C&D recycling/diversion
• Working with local business - promote recycling, resources use
• Regional Grant applications
• Market development – organics, dry recyclables
• Council activities, purchasing/procurement, recycling activities
