- the ash produced from incineration is transported to the Semakau landfill in the 6 barges
- transported and deposited in designated sites
waste stream created
waste - recycling - waste to energy plant (W2E) - Semakau
benefits of the incineration
- the plants are fitted with pollution control equipment
- heat from combustion drives turbines to produce electricity
- helps to conserve landfill space
overall benefit of semekau
has seen an increase in recycling rates and waste growth has reduced
how does incineration help
it reduces the volume of waste by 90%
size
3.5km^2 of space - will hold waste up until 2045
how have they reduced environmental issues
there is liner/ protection net to stop chemicals from the waste entering the sea (stopping leaching
