The first stage involves ___________________________________________________________________ _______________________________________________________________________________________ Subsequently comes the second and the most significant stage of the whole process. The bottles are categorized by their colors into green, brown and clear after being washed by high pressured water and then are sent to another glass factory. In the factory, the bottles are smashed into pieces and poured into a furnace to be heated. Having been melted from solid into liquid, they flow into a mould, in which glass liquid from other sources is added and the molding process takes place. In the final stage, new, empty bottles are filled with liquid, then packed and delivered to supermarkets ready to be picked by consumers. The whole process doesn’t come to an end until this step and a new cycle is set to begin.
