Most kitchens tend to be built using pressure treated wood, which we recently found out include tons of toxic chemicals that can off gas for years. One way to avoid mixing cooking with chemistry is to opt for woods that haven't been treated, such as cedar (which is a great natural bug repellent) or with glass and aluminum. Valcucine not only developed a kitchen made entirely of recyclable aluminum and glass, but built it without using harmful glues.
The frame for the kitchen's base unit is made from recycled aluminum, which uses just 5% of the energy normally used to manufacture aluminum. The entire kitchen is put together with mechanical joints, rather than glue, so it can be disassembled easily and its parts reused or recycled. Plus, no glue means no off gassing.
The kitchen ships flat packed, so that shipping containers are more efficiently used, and once recycled glass is available in sheets, Valcucine plans to use them to build this already green kitchen.
