“Can you eat old sportswear?” That's the unusual title of a short video on Houdini's web store about the “Houdini Menu,” broadcast by the Swedish sportswear company to support its sustainability claim. It features a composting expert, Gunnar Eriksson, and a Swedish chef, Sebastian Thureson. Houdini says it took it several years to develop apparel that could be completely recycled, mixing merino wool with other biodegradable textile materials. The company decided to test the validity of its claim by decomposing samples from its 100 percent natural wool baselayers in the soil. The vegetables grown in the soil were used for a tasty dinner cooked by the chef and served to some of the company's employees, who ate it. Eriksson says in the video that he never used clothing in compost before.
