3. Thermal Recycling of Plastics: Plastic is used as fuel to generate energy.

(1 t EOL plastic = 1.3 t coal in cement kilns)

Switzerland and Denmark thermally recover 70% of their waste plastic in 2002.

In 2003, 23% of total waste plastic of West Europe thermally recycled which is the largest portion in recycling methods.

Solid plastic waste combustion facility must have wet scrubber (APME).
