As well as prevention, more must be done to recycle our waste. Again, this comes down to education. Until people realise it is their responsibility to recycle, we will continue to see plastic bottles, aluminium cans and tonnes of paper needlessly disposed of as general household waste. Despite the great leaps forward taken in developing our recycling policy, we are still not recycling enough. Perhaps the best way to change the mindset is to offer a deposit on cans and bottles and other generally recycled materials. In a number of European countries, a deposit on glass bottles is still offered. Even if it were minimal, Irish people would be far more likely to recycle their waste if there were some monetary return for doing so. In some ways such a policy would be an extension of the polluter pays principle. By introducing it, we would be rewarding those who do not pollute but instead recycle. It would only add to the success of the polluter pays principle, which has already done much to influence Irish attitudes to waste. Despite some recent difficulties here in the capital, this policy has had a great effect in dealing with the waste issue.
