Our Glass pebbles are made from 100% recycled glass bottles and jars. We take waste glass from bottle banks and used vehicle windscreen depots. Thirty days after you drop your waste bottles or jars to the recycling bin, it can be transformed into a beautiful piece of coloured glass aggregate, rock, sand or pebbles. If it were not possible to recycle glass, it would end up in a landfill. One glass bottle can take up to 3 million years to break down.
