Bigger the market, greater the quantity of food waste per unit of time. Supermarkets waste too much edible food because the inherent shelf life and the lack of techniques to counteract the problem.
An interesting solution that avoids the complete loss for the supermarket is to establish a price reduction point before the shelf life exhaustion. Multiple supermarkets are following right now this technique that improves margins, but not all.
Another is freezing, as numerous areas of the supermarket could benefit from it. With warnings to the clients, in a specific zone, a lot of them would collaborate in the task of avoiding food waste, and at the same time saving a bit of economic resources as well.
The third comes with the help of third companies that rescue the aliments to be processed improving their shelf life, so part of another products, as raw supplies. Specially those that lack appearance, with a bit of work in the exterior they are perfectly useful and for that reason any other company should benefit for them at a lesser price.
Restaurants or other dinning areas also can benefit because they work for the day or for the following ones. So with collaboration, this is possible.
The seller should understand that relying on luck doesn't help anyone. The plan is to select a time to start these operations, like a critical point of no return where to wait for customers is too risky for being considered. In two days for instance, if the product irremediably expires, these are the days for starting salvage operations allowing other parties to be involved in the solution.
The provider knows what could happen with misuses and who finds a viable method to save in products for their businesses. Nevertheless, the seller selects the periods and with this it has a control method to avoid those chains who might depend on products near the expiration date. Furthermore, even allowing these operations, the gain is more than the entire waste.
There is the possibility of creating a technology-based market for anyone interested on those common products that are normally wasted in supermarkets. Where markets announce what they have, promoting supply contracts or simply online pick-up warnings for the clients.
The government, also may create regulations, or at least collection and distribution services to handle issues like poverty and homeless individuals. Besides it allows to create jobs.
It's better to not strictly depend on food in the imminent shelf life exhaustion, although if it's ready, better for three reasons. First it avoids over-exploitation of the natural regeneration cycles in the soil; in terms of logistics is a disaster. Second the seller avoid loses and finally other companies or clients also experience benefits in a form of symbiosis for the task of never throwing a single nutrient with impacts to the environment and psychologically in context, where so many people still experience hunger.
