Glass bottles: how recycled?

Glass recycling is a sustainable activity that involves crushing glass into cullet and mixing it with other raw materials to create new shapes. Homeowners must sort appropriate containers into take-back bins, and the recycling facility must clean the bins and remove labels and caps. The glass manufacturer exports manufactured glass containers wholesale to product manufacturers, who use them as packaging. Users can choose to reuse, discard, or recycle the packaging, and if they choose to recycle, they must remove caps and labels before placing the glass containers in appropriate bins.

Glass recycling is considered by many to be a sustainable activity, in which man seeks to preserve biodiversity and the environment. Being fully recyclable, glass bottles are an important component of the three Rs of sustainability: reduce, reuse and recycle. Glass can be crushed into a basic form called cullet and mixed with other raw materials, including silica sand, soda ash, and limestone. This mixture is heated until it melts, turning into liquid glass which can be formed into new shapes. After the glass manufacturing process, glass containers are used to hold all kinds of food and beverages and can be used over and over again.

The glass recycling process has specific standards that start from the consumer side. Before curb and other recycling programs send vehicles to take recyclable glass containers to the factory, homeowners are encouraged to sort the appropriate containers into take-back bins, which is the first step in the recycling process. A restricted sorting process excludes container glass which is considered contaminated; that is, those that contain foreign materials such as ceramics and light bulbs. Glass with foreign material is no longer considered pure, would create problems in the recycling process and is therefore considered non-recyclable.

If the homeowners haven’t already done so, the recycling facility must then clean the bins, removing labels and caps, before the rest is shredded into scrap. Caps and labels that are not removed can damage glass-making machines during the manufacturing process or end up making new low-quality glass containers that consumers are unwilling to buy and use.

The glass manufacturer is an essential player in the glass recycling process. First, he exports manufactured glass containers wholesale to product manufacturers, who use these containers as packaging for their wares. Goods are imported as wholesale retail to the consumer, who purchases the good for their own use. At this point it is the user’s responsibility to choose whether to reuse, discard or recycle the packaging.

If you choose glass recycling, follow the protocol by removing caps and labels before placing glass containers in the appropriate bins, to be taken to the recycling facility where it is either processed or declared unfit for recycling. At the plant, the process starts all over again in which crushed glass cullet is recombined with silica sand, soda ash and limestone to create more glass containers to perpetuate the cycle.
