Glass packaging is a unique, natural material
Made from some of the earth’s most abundant raw materials – sand, soda ash and limestone – glass is the purest, most natural material for food and beverage packaging. Long-valued by consumers for its ability to preserve the original flavor and color of products, glass is the healthiest packaging choice not only for us, but also for our planet.
One of the unique advantages of glass is that it can be endlessly recycled without any loss of quality to produce another glass bottle or jar, creating timeless packaging options. This makes glass the only true "cradle-to-cradle" recycling material. Of all the ecological initiatives implemented by governments across Europe, glass recycling stands out as one of the success stories to date. Strong cooperation between consumers, public authorities and the glass container industry has resulted in high recycling rates across most countries. Not only does recycling glass reduce landfill, it also decreases the need for raw materials and energy in the manufacture of new glass containers. Recycled glass, known as cullet, has a lower melting point than raw materials, which means that more glass can be melted for the same energy investment, emissions can be reduced and the furnace life extended.
Glass is the only packaging material that can be manufactured in a "closed loop". This means that because used glass packaging can be recycled again and again to create new bottles and jars, it never needs to go into landfill.
The following are the main ecological advantages of using cullet in the glassmaking process
Energy savings, since the collected glass melts at a lower temperature than raw natural products, and so more easily and faster;
Less CO2 emitted into the atmosphere: for every 6 tons of cullet used, the CO2 emissions are reduced by 1 ton;
Less consumption of natural resources, as the cullet replaces the raw materials (silica sand, limestone and sodium carbonate) used in the composition of glass;
Less waste and maximum recovery of household waste avoiding its disposal in landfills or incinerators.
