Through their thoughtful architecture, the four long, parallel structures that constitute this waste treatment plant achieve the facility’s central tenets: to connect with its environment, and to engage visitors. The sculpted buildings, which process 450,000 tonnes of waste each year, sink at one end into the rising topography and receive ample natural light inside. Visitors can enter via a plaza dotted with local orange trees to tour the plant and learn about energy conservation. israelalba.com
