Waste Management

• Waste management defined as the collection, transport, processing (waste treatment), recycling or disposal of waste materials 1

• Waste management involve solid, liquid or gaseous substances • Key feature applied is focus on energy conservation, material

development and integrated waste management 2

• Eco-town will make residents and businesses more easy to reduce and manage their waste in sustainable way as provision of mechanisms, facilities and services 3

Expectation outcomes for sustainable waste management• Demonstrate excellence of environment sustainability in

technological such as wastewater treatment or grey water recycling and waste management systems to enhance sustainable behaviors among community

• Incorporate environmentally sustainable approaches to managing waste, waste water, drainage and flooding

• Integrate green space and features to enhance biodiversity• Use construction methods and materials for low environment

impact and minimum construction waste

Zero Waste concept

Reconfigures the current waste management culture to a value recovery cultureEncourages new ways of thinking Shifts from linear resource use and disposal cultural to a ‘closed-loop’ system [DIAGRAM]

Maximises recycling, minimises waste, reduce consumption and ensures that products are made to be re-used, repaired or recycled back into nature

Aims to meet Zero Waste conceptstated by Town and Country Planning Association(2008),Towards Zero Waste: Eco-towns Waste Management Worksheet ,London

• Encourage households & businesses towards a cultural change (waste hierarchy and use resources efficiently) in life and work

• Set targets for waste minimisation & achieve best practice• Recover maximum value from residual waste and zero waste to

landfill for all waste streams-diverted to alternative treatment and disposal

• To cover other producers : municipal, commercial and industrial• Reduce greenhouse gas emissions from waste and resource recovery-focus on building & transport

Waste to Energy(WtE)

Definition• WtE or energy from waste its strictest sense refers

to any waste treatment that creates energy in the form of electricity or heat from a waste source that would have been disposed of in landfill.

• More advance of WtE processes result in usable fuel commodity, such as hydrogen or ethanol.

(Wagner, 2007)

• The use of modern combustion technologies to recover energy, usually in the form of electricity and steam, from mixed municipal solid wastes.

• These new technologies can reduce the volume of the original waste by 90%, depending upon composition and use of outputs.

(Wagner, 2007)

Eco-town Biodiversity Strategy

Definition• Biodiversity is a modern term which simply

means " the variety of life on earth”, (Corker, n.d)

• Biodiversity is the richness and diversity of habitats and species within a given area (TCPA, 2009)
