Consumers are willing to pay up to an extra £108 ($197) for a PC containing fewer chemicals, a survey has found.

Obviously this is a large concern - amongst those who desire powerful PCs upgrades may have to be performed every other year, meaning a lot of old components that need to be dumped. I recycle bottles, cans, bags, paper and food waste - but if some computer equipment has to go it can only go to the tip. Either they need to start making things such as the casings from better biodegradable or recyclable materials, or the government must provide a public service for recycling of the components through re-use.
