What they looked at was the lifecycle of each type of closure to work out the cost to the environment of 1,000 closures, in terms of energy, water consumption, air pollution and solid waste. The cork industry has been saying for a long time that cork is one of the most environmentally friendly products on the planet, as it comes from sustainable indigenous forests, where the trees are not cut down when the cork is harvested, but left to regenerate so that they can be harvested again.<\/p>\n<p>However, even given the fact that cork trees themselves are obviously only of benefit to the environment, processing the cork obviously has an environmental cost, because it requires machinery for some parts of processing (although natural cork production is still largely manual),&nbsp;transportation, disinfecting&nbsp;and so on.
