Bioplastic bags from NaKu

Bioplastic bags from NaKu keep food fresh longer and prevent it from ending up in the bin.

One third of all food worldwide ends up in the rubbish. In the EU, 173 kilograms of food are thrown away per person every year. This amounts to a total of 88 million tonnes of waste per year. In Austria it is 760,000 tonnes. A good half of this is considered potentially avoidable. 53% of all food thrown away is the result of private households. In an average household, a quarter of the food purchased is thrown away and ends up in the dustbin. The main causes are poor shopping planning, improper storage and misunderstood best-before dates. Vegetables, bread and dairy products top the “throwaway” list.

Why do we throw food away and not save it from the dustbin? There are many misunderstandings about the best-before date (BBD): It is not a “recommended throw-away date”. Rather, it can be compared to a guarantee. No one would throw away their electrical appliances after the guarantee has expired. The same should apply to food.

Most consumers do not check their food. However, if a product still looks, smells and tastes good, then it can be eaten without hesitation even after the best-before date has expired. There is also room for improvement in terms of storage. Many people store their food unsealed or loose, exposed to the air, which can reduce the freshness of the food. NaKu has a solution for exactly that.

NaKu keeps food longer fresh

Our biogenic packaging made of natural plastic is particularly breathable. Packaged baked goods, fruit and vegetables stay fresh longer in a breathable environment and are less prone to mould.

The material and manufacturing process of NaKu bags have been perfected over the years to create an optimal climate for storing food in the bags. The taste, appearance and weight of the food are hardly changed by storage. There is less bacterial contamination and dehydration is counteracted. You can thus preserve the quality of the food for longer and thus keep it from being thrown away.

By storing their food in NaKu sacks, they save valuable food resources, the environment and their wallets! Less food thrown away also means less CO2, just think of the unnecessary transports that are no longer necessary.

Freshness study

A study shows that fruit, vegetables and bread in NaKu organic sacks stay fresh longer. The food was stored in three different ways in the course of the study: open, in conventional plastic bags made from petroleum and in NaKu bags made from natural and rapidly renewable raw materials from European agriculture. Apples, mangoes, tomatoes, lettuce, egg mushrooms, bread and rolls were examined.

The foods were evaluated over different trial days for appearance, smell, taste, weight loss and infestation of microorganisms. Subsequently, the products were ranked according to storage variant with regard to their evaluation and an overall rating was made. For all tested foods, the NaKu sack made of natural plastic performed better than the conventional plastic sack made of petroleum and open storage. Open storage was second best. On the other hand, the products from the conventional plastic sack were without exception rated worst by the tasters in terms of taste.
