How do objects that have lost their value become valuable once again? Rubbish is something we ignore. By definition we discard it, from our lives and our minds, and it remains outside the concerns of conventional economics. However, this book explores the dynamics through which rubbish can re-enter circulation as a prized commodity, in many cases far exceeding its original value. Antiques, vintage cars and period homes, after being discarded as valueless, can, even after many years, become priceless. First published in 1979, Rubbish Theory has become foundational in its field. Today, it is as relevant as ever. This edition includes a new afterword revealing how the consequences of our compulsion to discard are far from inevitable, and going on to explore how we can transform our troublesome wastes into valuable resources.
