incineration - AEB Amsterdam - CUE Flashcards
main Dutch approach
- to reduce waste
- this can be done through recycling
- main use of a waste to energy strategy
landfill tax
from 1995 - 2012 a tax was place on every tonne of waste that went into landfill
- they were able to stop the tax as very little waste was ending up in landfill
energy produced
- 1 million mega watt hours of electricity annually
- 300,000 gigajoules of heat annually (creates heat for several Amsterdam communities)
amount of waste
1.4 million tonnes of waste a year is bought to waste to energy plants
percentage of receyled
64% of waste at the plant is recycles
water plant
the incineration plant works with the next door water treatment plant
- incineration plant provides energy and heat for water treatment
- water treatment plant injects its sludg and biogas inot incineration as a fuel source
environmental benefits of the plant
installed a process of scrubbing the flue gasses
- close the loop for other by-products so they can be used in other industrial processes - material left becomes landfill
- saves 438 kilotons of CO2 (would be 1036 kilotons produced if same amount of waste was in landfill)
what happens to the waste
- 99% of recycled waste is transformed into raw material and energy
- they recover raw such as cooper and other valuables
- rest of the raw materials are used as freely usable materials such as in road construction
- they want maximum recovery of raw materials
- metals are recovered from the ash
- ash is used in constriction for primary building materials such as sand and gravel
- want to re-used 100% of the ash in infrastructure projects
electronic waste
electronics can be sent to the plant where they are disassembled and parts will be separated and sent to the right processors
- 80 % of material from devices is still reusable
plastic bottles and cartons
- bottles = re-used to create things such as garden chairs and plastic bags
- cartons = tissues
