Guess What ? Modern Incinerators in Denmark
Dutch architect Erick van Egeraat has been contracted by the Dutch
Board of Waste and energy supplier KARA/Noveren to design a new
waste- to-power incineration line in Roskilde, Denmark. The
contract was won by van y Egeraat in a competition in 2008, where
he proposed a design that embraces both the historic and industrial
heritage of the region. The new incinerator plant features a
striking punctured façade and it is expected to be finished in
2013, when it will start to process large amounts of local waste to
produce electricity and heating for the region.

Matching with Surrounding Environment
• Make use of Shek Kwu Chau to screen off structures
• Minimize site layout and footprinty p
• Emphasize nature as the design concept ; provide extensive
landscape
areas & greening
IWMF

• Use of silt curtain
• Control of dredging and filling rate
• Use of quiet machinery

EIA Study Conclusion
Tsang Tsui
With advanced technologies and implementation of appropriate
mitigation measures, construction of modern incineration facilities
at the two sites is environmentally acceptable
