Contribution of Soarnol™ to sustainability

Contribution of Soarnol™ to sustainability

The Sustainable Development Goals (SDGs) adopted by the United Nations in 2015 are global efforts aimed at achieving by 2030, setting 17 goals to create a prosperous and energetic future.Soarnol™ will work to solve social issues and contribute to the SDGs as a member of the international community.

2.  End hunger, achieve food security and improved nutrition and promote sustainable agriculture

2.1: By 2030, end hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round.

12.  Ensure sustainable consumption and production patterns

12.3: By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses.

Ensuring food safety

Barrier packages with Soarnol™ can prevent corruption of foods and ensure food safety even for a remote place where takes time to deliver foods.

  • Extend a shelf life
    Extend a shelf lifeExtend a shelf life

    By using EVOH, corruption of foods are prevented and shelf life can be extended.

    Example...

    ・MAP (Modified Atmosphere Packaging)
    → Skinpack for fresh food (meat and fish) and ready meals
    ・High barrier cup for drinks
    → jellies and yoghurt

Reduction of food loss

By using Soarnol™ which has superior gas barrier properties to other resins for food packaging, freshness of foods are kept longer and shelf life can be extended.
Soarnol™ has great contribution to a reduction of food loss, an issue facing the international community.

  • Keeping freshness

    Even after opening a package, prevent oxidation of foods to keep their freshness.
    Reduce food wastes due to deterioration of freshness.

    Example...

    ・Bottle for seasoning
    → soy sauce, edible oil and soya paste
  • Individual package

    Request for individually packed foods is increasing due to diversity of life style.

    Packages for such a food has larger specific surface area than that of conventional packages and for that reason, Soarnol™ which has high gas barrier material is necessary.

    Example...

    ・High barrier tray and cups
    → rice, coffee, pudding, chips, etc.
    ・Barrier films
    → ham, cheese and so on.

A waste of foods is the one of the most important issue to be solved in the world. The amount of the food waste is totally 1.3 billion ton from all over the world and this reaches 1/3 of the food produced*1.
On the other hands, a number of people who are in starvation and malnutrition is around 800 million*2.
A population in the world is forecasted to continuously grow*3 (9.7 billion in 2050, 7.5 billion as of 2017), so optimal usage of food is an important topic.
United Nation decided following targets called “SDGs”, namely, “By 2030, end hunger and ensure access by all people, in particular the poor and people in vulnerable situations, including infants, to safe, nutritious and sufficient food all year round., “By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses” and an ensuring food safety and reduction of food loss are subjects to overcome in the world.

Contribution to reduction of plastic usage

SDGs goals and targets contributed by Soarnol™

12.  Ensure sustainable consumption and production patterns

12.5: By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse

14.  Conserve and sustainably use the oceans, seas and marine resources

14.1: By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollu

Request to reduce plastic usage is getting bigger and bigger, but functions of package must be kept as same.
By using Soarnol™ which is high gas barrier resin, we think an amount of plastic could be reduced while keeping required properties.

Case 1:
Substitution from other resin to Soarnol™

By changing thick resin layer which has low barrier property to thinner Soarnol™ layer, both reduction of plastic and same barrier property can be achieved.
For example, make monolayer PA film to PA/Soarnol™/PA film, an amount of plastic becomes lower with same gas barrier property.

Case 2:
Substitution to higher gas barrier grade of Soarnol™

Even Soarnol™ has already been used in a package, changing to high gas barrier grade (lower ethylene content grade) makes gas barrier property same as before and reduce an amount of plastic usage.

Development on recycling technology of multilayer package

Mitsubishi Chemical already developed and commercialized Soaresin™ RG series to contribute a reduction of plastic package waste.
It is common to reuse scraps which generated in a process as regrind layer when a customer produces multilayer package with Soarnol™. Since EVOH and polyolefin is difficult to make compatible, transparency and mechanical properties of a regrind layer is an issue to use easily.
Nevertheless, by adding Soaresin™ RG series developed by Mitsubishi Chemical, the compatibility of EVOH and polyolefin could be improved and it is possible to have high quality regrind layer so Soaresin™ is widely used especially by sheet producer. This Soaresin™ technology contributes to reduction of plastic waste by reusing scrap plastic as regrind layer.

Multilayer package with EVOH is considered as recyclable in US and Europe.*
We, Mitsubishi Chemical continue developing further recycling technology to improve recyclability of multilayer package with Soarnol™ to meets requests for recycling of multilayer package from the world.
