On a computer, it is easy to delete software and files by sending them to the recycling bin. Text messages, TV programs, music, and photographs can also simply be deleted. If they couldn't, our tech products would fill up and grind to a halt. However, the situation isn't quite so straightforward when it comes to getting rid of the hardware itself.

The rate of demand for technological invention has resulted in annual sales of technological consumer goods (TCGs) growing year after year. In 2008, for example, global sales of TCGs increased by 14 per cent to $694 billion. Some of this growth is due to new users buying TCGs in developing economies, but the vast majority is the result of users in developed economies replacing existing equipment. The resulting problem is disposal of the old equipment. In the United States, 80 per cent of TVs and 70 per cent of computers end up in landfills, and nearly 200 million old PCs are being kept in warehouse facilities. According to the U.S. Environmental Protection Agency, another 40 million PCs could join them in the next few years. Unfortunately, the challenge doesn't end there.

According to the United Nations Environmental Program, the sheer volume of discarded technological consumer goods also called "e-waste," could be as high as 50 million tons per year worldwide. Not only that, but e-waste contains toxins, such as lead, cadmium, and PVC. An increasing problem is that some e-waste is now being disposed of in countries not equipped to deal with it. It is estimated that California alone shipped about 10,000 tons of e-waste overseas in 2006, and 40 per cent of that was sent to developing countries such as Malaysia, India, Ghana, and Brazil. Ineffective waste disposal in these areas has led to higher levels of environmental pollution and dreadful medical conditions, such as cancer in adults and birth defects in babies.

However, there are several possible solutions to curb this growing tide of e-waste washing up on the shores of developing countries. First of all, there needs to be more consumer awareness and use of specialist recycling companies in developed economies. At present, only a token 20 per cent of e-waste is disposed of in this way.

A second solution could lie with greater global regulatory and legislative power. In the early 1990s, a campaign was mounted to stop trade in e-waste, and in 1995 an international ban on hazardous waste being shipped to developing countries was signed. The European Union has subsequently woven this agreement into its legal framework. Unfortunately, the United States has yet to sign up, and illegal trade in e-waste by companies wanting to bypass expensive waste treatment processes or earn much-needed foreign currency continues to grow.

An alternative to these solutions is to shift the burden from consumers and governments to manufacturers and retailers of high-tech goods. Since they are the ones profiting from technology sales, they should be part of the solution. For example, more companies now collect and recycle old technology and are looking at ways to make their equipment "greener." For example, equipment could be made with fewer harmful substances, making it easier and cheaper to recycle. It could also be made of more recycled components. Finally, green equipment could be designed to have a greater scope of possibilities in terms of updating, therefore minimizing the need for replacement.

Perhaps we are now turning the corner in e-waste management as stronger laws and penalties and growing corporate accountability are all starting to have an impact. However, without us actively seeking ways to rethink our development and use technology to protect the planet against further environmental damage, these measures will only make a small dent in an ever-growing pile of waste.
