Sustainable Food Packaging

N2 with 3% H2

For instance meat get in contact with microorganism, oxygen and can rotten in fact. Fish protective muscle are thin so that can rotten so easy.

Its depend on the packaging system, on the one hand we have vacuum packaging the old system and the MAP

It harms biological growth of microorganism

1. It would lead to collapsing because it permeate 16x faster then nitrogen

2. Taste not good we don’t want negative impacts in case of taste

A liquids oxygen content can be much higher in a cold liquid then in a warm liquid.

We can have a transparent packaging and add UV filter to increase the shelf life

If we remove the oxygen in the atmosphere of the packaging, the photooxidation cant occur.

photoxidation need 2 % oxygen if we now have only 1% oxygen, we have no problem with coloration.

With 0% oxygen we have no coloration at all

Decrease the storage time because of a photooxidation. Green substances are additional sensitizers

Reduce the headspace of the packaging.

Only the listed raw materials are allowed!!!

The overall global migration restricted to 10 mg/dm2 resp. 60 mg /kg

sum up all the monomer migrations and look are you below the 60mg/kg

the seller, but the seller protect them self with a document of complience from there suppliers

blow up to protect the chips is filled up with nitrogen, the nitrogen permeate from in to outside a bit lower than o2 permeat inside so the blow is maintain over the storage time

because co2 goes out faster than o2 goes in

Too high permeation rates
• Delamination
• Strong thinning during thermoforming
• Storage condition are not considered
• Moisture is not considered (EVOH)
• Seal seam defects
 

Pro:

Preservation of the metabolism
in fresh fruit / vegetables
 

Color preservation of fresh meat

growth of
anaerobic microorganisms
(toxin producers)
 

Cons:

• Degradation of nutritionally relevant
substances (vitamins, proteins, lipids)
• loss of taste
• discoloration
• growth of aerobic microorganisms,mold
• Production of toxins

 

pro

• bright salesroom
• transparent packaging
• contents should be clearly
visible (consumer acceptance)

cons

• light-catalyzed
• oxidation reactions
• photocatalytic autoxidation
• photosensitized oxidation of fat
• discoloration
 

Photocatalyzed autoxidation is a reaction between fatty acids and UV light (more Energy, lower wave lengths)

Photosensitized lipidoxidation is a reaction between fatty acids and visible light (less Energy higher wavelengths)

Oxy-myoglobin shows a clear UV dependence (light-induced autoxidation)
 

fresh dark red meat (without oxygen)-> myoglobin

Red meat color defined by O2 partial pressure Avoid prolonged storage at 5 mbar -> met- myoglobin 

light red meat (with oxygen)-> oxy- myoglobin 

global warming

low-carbon economy

care about nature

green energy

long shelf life

protection biodiversity

use less

resource efficiency

generational responsibility

4. Quality education can provide knowledge about the right way to seperate garbage so there is the possibility of recycling of packaging components afterwards

We have to consider the energy demand we need (primary raw material, producing, packaging, transport and waste)

Material waste

Possible Material re-use rate

Total cost of the packaging

Landuse rate

2. Zero hunger correlates directly with packaging (safer food, longer shelf life, less food waste).

3. good health and well-being is also linked to packaging because a good packaging option helps to provide "safe food" for a longer period of time

For me personally, the price is currently the point of conflict. I would like to buy more qualitative products and cook fresh.

I also want to buy vegetables or fruits which packaging is not necassary but the food safty is always given.

3-pillar model

sustainability triangle

The intersection model

Priority model

In the business sector, sustainability is described according to the 3-pillar model and thus classified into three categories: Ecology, economy and social issues are the pillars of sustainability in this model. Symbolises idea of weak sustainability i.e. natural capital can be fully substituted by other forms of capital (human capital and physical capitol)

The sustainability triangle, which links the three principles, is to illustrate that sustainability can only be reached if ecological, economic and social aspects are taken into account.

The triangle is designed with equal sides to underline the equal value of all sides

The overlap model has three overlapping dimensions where the common intersection is sustainability
It is usually limited to the balance of the dimensions

The priority model has a "strong sustainability" and considers ecology as the basis for society. The society forms the basis for the economy.

he cradle-to-cradle principle is based on nature. Because biological cycles leave no waste behind. At the Moment we have from cradle to grave, we can’t use all materials over and over.

The bioeconomy means using renewable biological resources from land and sea, like crops, forests, fish, animals and micro-organisms to produce food, materials and energy.

Opportunity:

-the exhaustion of resources for future

- Protect the stability of the planet

- Transition to sustainable economy that is less

Dependent on fossil carbon.

Risk:

-Competition with food production

- negative impact on biodiversity

- Increased production in agriculture and forestry

Forestry can mean additional emissions, land and resource consumption

The European Green Deal regulates the transition from the currently dominant linear economy to the circular economy

Then we have the Reduction of the demand for primary raw materials and could also help achieve climate neutrality by 2050 and preserve biodiversity (short term 2030)

Decouple economic growth from resource consumption

1. avoidance, Each Packaging is avoidable when the packed don’t fullfill the function of the food safe

2. preparation for reuse,

3. recycling,

4. other recovery, especially energy recovery and backfilling,

5. disposal

- Overall at least 55 percent by weight from 2025,

- a total of at least 60 percent by weight from 2030,

- a total of at least 65 percent by weight beginning in 2035.

Goals:

- Harmonization of national measures for the management of packaging and packaging waste.

- To improve the quality of the environment by preventing and reducing the impact of packaging

directive (EU) 2018/852 (as the latest modification of guideline 94/62/EC).

- Preventing the production of packaging waste

- Promoting reuse, recycling and other forms of recovery of packaging waste instead of final

Elimination

Minimizing the use of primary resources and waste generation through long product life cycles and

Raw material -> production with energy -> use phase -> preparation for reuse -> use phase -> End of Life -> recycling (technical lifecycle) or composting  (biological lifecycle)-> bring us new energy or material (humus for plants to increase the Fertility)

Cultural: mentality, no understanding and interest, (difficult to make the whole value chain to be circular).

Technological: lack of proven technologies and recyclable designs, difficulty in

Production of high quality remanufactured products.

 Economic: low prices for new materials, often high upfront investment

required, limited availability of financing.

Regulatory: lack of policies to support the transition to a circular economy,

barriers to legislation and regulation

When all of us get the same demand of fossil fuels and the CO2 footprint of each of all is the same

People with the best performnce get the most
