  • Packaging used for containing liquids can generate large amounts of waste. In some cases, packaging used for containing liquids can be recycled. Packaging used for containing liquids has been described in PCT Publication No. WO/2007/0066090, which is herein incorporated by reference in its entirety.
  • bottles made from plastics such as PET or HDPE
  • liquid such as water, juice, carbonated drinks, or milk
  • the bottles it is common for the bottles to be formed from virgin, i.e. non-recycled, material to ensure that the liquid contained within the bottle is not contaminated as could be the case if the containers were formed from recycled material. While the material itself could be recycled if separated from other waste, as with glass bottles this frequently does not occur due to the need for the waste producer, such as a householder, to separate the containers from other waste material. Again, if the container is disposed of in a landfill site or the like, the bottle is not biodegradable. Also, bottles take up a volume larger than that of the material itself due to their hollow, rigid, structure, and therefore take up an excessive amount of space in a landfill site.
  • the cardboard from which the body of the container is formed may be virgin or recycled material.
  • the cardboard is laminated with a waterproof coating. This ensures that the container is able to hold liquid and also acts as a barrier between the liquid and the cardboard, which can prevent contamination of the liquid from the cardboard. This is especially needed where the cardboard is formed from recycled material.
  • a problem with such packages is that they are difficult to recycle, and the waterproof coating prevents them fully decomposing. The problem is exacerbated when a plastic dispensing nozzle or cap is formed as part of the package for dispensing the contents. This is another component that would need to be separated before the container can be recycled or parts of this be allowed to decompose.
  • liquid such as milk is packaged in bags.
  • these bags have little structural stability, and therefore are difficult to transport and to stack on shelves. They are often not re-sealable, making them hard to hold and carry.
  • bottles or other liquid containers contain additional, separable components that do not make it into a recycling bin.
  • additional, separable components For example, loose caps, straws, and plastic tamperproof or tamper-evident devices can contribute to overall litter in the environment. Even if bottles make it into a recycling bin or garbage can, their caps or other types of closures often end up as general litter.
