New York Times: If you’re itching to visit the new advanced waste management plant that will open in 2016 in Copenhagen, be sure to bring your skis, writes Jim Witkin for the New York Times. An urban ski park will cover the plant, which will incinerate the waste from five municipalities to generate heat and electricity for 140 000 homes. While their trash is burning inside, locals will be able to take an elevator to the top of the building, then ski down one of three different slopes. Although municipal incinerators in Europe often take on decorative coverings to overcome negative public perceptions, the Copenhagen plant will be the first to engage the public in a sport. Designers call it “hedonistic sustainability"—sustainable cities and buildings that actually increase the quality of life.
