By considering the life-cycle impact of each step, from raw material through the manufacturing process and through the product's end of life, sustainable choices can be made. Design considerations can include using recycled materials in the manufacturing process, reutilizing found furniture and using products that can be disassembled and recycled or reclaimed after their useful life.
