Introduction

Construction+Engineering = does not support environmental welfare

Reducing demand upon new resources

Minimising costs in the transport and production energy sectors

Preventing Landfills

Promoting Sustainability

Qld is largest waste contributor in construction industry

QLDs construction industry continually expanding = more waste

Australia deposits 45% (8.5 million tonnes) of its C & D waste into landfill per year

Benefits of proper waste management schemesProblems in Queensland

Maintaining a healthy recycling environment

Resources are not infinite

Economic impacts

Social impacts

Discussion

Importance of recycling Construction Waste

Lack of Gvt incentive

Complexity of waste C&D waste management

Companies lack experience/no set rules

Discussion

Problems with the management of C&D waste in Queensland

Waste reduction and recycling strategy 2012-2020

Waste disposal levy for C&D and C&I

Waste disposal levy < $30/tonne

Discussion

Queensland Current Methods

Distribution of Levy Funds

Fairly allocates levy on waste production levels

Innovative development of new recycling technologies

Increase landfill diversion rates

Discussion

New South Wales Levy increase and separation of regulated areas

Makes recycling more attractive

Establishes effective/efficient framework between stakeholders

Establishes fluent collection-transport-dumping/recycling of waste process

Economically better for companies

Discussion

Bangladesh Third party waste management companies

Saves city council money

Higher landfill charges = more cost-benefits in long run

Higher charge scenario had cost-benefits of nearly 10x that of low charging scenario!

More effective waste management schemes are identified

DiscussionShenzhen Statistical analysis: higher landfill charges create greater cost-benefitsLow charging levies = No economic return until halfway through duration of project

95% of processed material can be reused

Involves simple treatment methods

Promotes conservation of energy

Discussion

Netherlands The Close Cycle Construction conceptReduces waste production

Combusts C&D waste in thermal process

QLD levy too low > attracts waste from other states

QLD levy too low > companies still use landfills

QLD levy too low > waste management schemes not developing

Results

Comparison of Queensland to New South Wales and ShenzhenQLD levy too low > drastically lower cost-benefits for companies

QLD does not have sufficient regional levy costs

QLD has no proper mitigated partnerships between stakeholders (City council, construction companies, third party waste management companies)

This leads to no economic incentives such as price reductions

QLD has little to no cohesion between stakeholders > inability to efficiently manage waste

Results

Comparison of Queensland to Bangladesh

QLD doesnt have processes such as The Closed Cycle Construction concept in place

QLD landfill usage will continue to rise

QLD is missing out on the ability to reuse of 95% of its C&D processed material

Results

Comparison of Queensland to NetherlandsQLD is landfilling possible recyclable material

Review/Improve on waste management plans

Contribute levy revenues received by the Queensland Government that exceeds forward estimations towards building waste programs

Different levies for metropolitan and regional areas within Queensland

Conclusion

Proposed Improvements for QueenslandPropose an additional interstate levy for companies travelling interstate to dump waste

Incentives for third party waste management companies that focus on recyclingCompulsory company education on recyclingSupport investment in resource recovery facilities to improve the reprocessing of easily recycled building materialsInvest Queensland Levy funds into The Closed Cycle Construction concept

Increase Landfill disposal charges/levy

NSW disposal levy for respective regions (NSW Gvt, 2015)
