Metal packaging, whether manufactured from aluminium or steel, fulfils every requirement of sustainability and can boast a low environmental impact. According to the Steel Recycling Institute, 63 per cent of steel cans are recycled and these items are originally manufactured from 32 per cent recycled material. The Aluminum Association indicates that 52 per cent of aluminium cans are recycled. The metal packing industry continues to design and manufacture lightweight, strong, flexible packaging products.
Plentiful Raw Materials
The raw products from which metal packaging is made, aluminium and iron, are the third- and fourth-most-abundant elements in the planet's crust. According to European Metal Packaging, three-quarters of all aluminium that has been used is still available through recycling, or is still in use. Nineteen billion tons of previously utilised steel is still available through recycling, or is still in use. Metal packaging becomes lighter each year and through recycling, the metal-packaging industry is producing more containers with less raw material.
Safe, Efficient, Economical
Metal cans offer 100 per cent protection against contaminants, moisture and oxygen. They also protect their contents from light and gases. These metal tins are unbreakable and lessen the percentage of domestic waste, when compared to other types of packaging materials. Because metal cans are hermetically sealed, they allow their contents to be kept for extended periods and still retain all of their benefits. This is not true of other packing materials. Metal cans are well-suited for holding potentially hazardous materials, such as domestic cleaning products and paints. Metal cans save resources by not requiring much secondary packaging. They save space in retail outlets, because they can be stacked higher than the majority of packaging materials. Metal cans avoid the need for refrigeration and their food contents heat up quickly. Both of these attributes are energy-savers. Metal cans retain the vitamin and nutrient levels of food products without requiring preservatives.
Superior Recovery Rates
Metal packaging is recyclable over and over again because metal always reverts back to metall. Metal has superior recovery and recycling rates compared to other packaging materials, and the recycling collection of metal packaging is cost-effective. According to European Metal Packaging, during 2006, the recycling of steel packaging saved 1.7 million tonnes of coal and 4.8 million tonnes of iron ore.
