Furniture is one of the trickiest categories when it comes to recycling. This is because most furniture is made out of many kinds of materials, such as wood, metal and mixed textiles, which must be separated before they can be properly recycled. Lichtenstein recommends trying not to buy furniture made of mixed materials in the first place, if possible. But if you want to recycle the furniture you already have, he recommends checking with local businesses that specialize in repurposing objects. "You might find a small cottage industry that's taking old furniture and finding a way to fix it or take it apart and turn it into something else," he says.
