Starting from Basics

The landfill has been a child of convenience. Historically, waste was simply dumped in depressions, ravines, and other handy locales that were close to the population centers producing the waste. For centuries this was an acceptable method, but two developments caused serious environmental difficulties with this approach. First, the enormous growth in population resulted in much more garbage being generated, at the same time as land was becoming a scarcer and more valuable resource. Second, the technological and consumer revolution led to the creation of many more hazardous products—particularly synthetic organic substances such as pesticides, PCBs, paint removers, and degreasers, which ultimately wound up in landfills. Landfills grew bigger, and their contents were more toxic than ever before. The child of convenience grew up and turned into an environmental ghoul. Instead of convenience, we need to seek methods of waste disposal that do not impair our environment, use up valuable resources, or place limitations on future resources. Changing engrained habits is not an easy task. We need a revolution that sweeps aside the old ways and introduces new concepts and technologies that are in accord with philosophies that value and protect our environment. Although the gravity of the situation is becoming recognized, and some positive steps—such as streetside recycling programs—are being implemented, there is still an enormous amount to be done. Perhaps we need a different outlook on waste disposal. We should seek disposal technologies and methods that protect the environment; furthermore, these methods must be based on fundamental philosophies that the public understands, agrees with, and buys into. When we seek to redesign waste management, it is important to start with the ultimate objectives firmly in mind. We need goals and a set of rudimentary principles to guide us. Many of us have read a science fiction novel in which a lonely spaceship has been sent to explore a distant galaxy, hundreds of light years away in the farthest reaches of the known universe. Even at hyperspeeds, the spaceship must travel for centuries to reach its destination, requiring several generations of crew to pass their lives aboard the ship.
