How the returnable vacuum works: the mechanisms that regulate thereturnableto save money and precious resources for the environment.

Thereturnableit is a system that allows the reuse of packages avoiding, therefore, that they end up in landfills. It is a form ofrecyclingwith multiple economic and environmental advantages.

Empty to lose or empty to return

When we talk about cans or plastic packaging, the term we use isvacuum to loseit is still recyclable materials (aluminum and PET) but which have a greater impact on the environment than glass bottles, thereturnable.

THE empty to lose are usually disposable materials, even if some companies produce disposable vacuums that could actually be reused, see the case of Nutella jars, they are still glass (and potentially empty to throw away) but there is no mechanism for recovery, with the exception of the creative recycling made by individually by citizens and glass-shaped jars of Nutella).

Only in rare cases does the phrase "returnable”Accompanies PET bottles, usually these are disposed of in the separate collection of plastic but some producers have experimented with the direct reuse of plastic bottles. It has been observed that a PET bottle can be reused up to 20 times

Returnable, economic benefits

A glass bottle, with the system ofreturnable, it can be reused up to 40 times so as to save precious resources such as raw materials and energy.

Returnable glass bottles can be returned by the consumer and then refilled about 30 to 40 times, in reality a bottle, in ideal conditions, can face up to a maximum of 50 cycles of use, after which it can be recycled as glass.

A new glass bottle contains 60 to 80 percent recycled glass.

Returnable, environmental benefits

The first advantage is the saving of virgin resources and the energy savings associated with the production of new bottles. Industrial production processes cause damage to the environment, in the case of glass bottles we speak in particular of air and water pollution.

A second advantage is connected to the lower production of waste. A third environmental advantage lies in the cuts in freight transport: most companies usereturnablewith its own products and deliveries to customers-distributors, in this way long transports and consequently also the related CO2 emissions are avoided.

The vacuum to make it even more efficient

If you think that the 30 - 40 life cycles faced by glass bottles are the non plus ultraof thereturnableyou are wrong. Returnable polycarbonate bottles can be reused up to a maximum of 80 cycles. Polycarbonate can thus be considered an ecological and practical packaging with good qualities for storage, low weight, resistance and maintenance of the quality of the content.

How the returnable vacuum works

The returnable void for citizens
Typically, those who buy the product in returnable pays a deposit which is returned upon return. A practical example: a user buys a drink that pays 1.25 euros including a glass bottle. When the user decides to return the bottle, the sum of 25 cents which served as a deposit will be returned.

In Germany, thereturnableit is very widespread in city culture. There are people who collect bottles of beer to present at the supermarket to get the deposit back. In this context, another environmental advantage is cleaner streets and public areas!

The deposit and the return of the vacuum
The deposit that the customer pays for the bottle usually amounts from 15 to 25 cents for "empty". The "vacuum" must be made clean and the user must be careful not to damage the bottles. Should the bottle be damaged it can no longer besurrenderand must be differentiated with the collection of glass.
