The tools needed to make these bioplastics are a pot, a spoon or fork, a stove, a measuring scale, a measuring cup, a blender, a mixer, a mold/sheet and the materials named in the recipes for the experiments.
The materials used in all the recipes are alginate, calcium chloride, corn starch, gelatine, glycerine, honey, potato starch, tapioca starch and water.
Tools Measuring scale Blender Glass plate Spray bottle
Ingredients 12g Alginate 30g glycerine 400g water 10g sunflower oil (used: olive oil) Spray bottle with calcium chloride
Method Mix the alginate, glycerine and oil together and slowly add the water while mixing to avoid lumps. Leave the mix overnight to take out air bubbles. Cast the mixture on glass with an approximate height of 3mm. Spray calcium chloride over the sheet once after casting and again after a few minutes. Leave the sheet to dry for a couple days.
Material properties
Conclusion The alginate foil is strong against pulling forces and will not tear when bended. However it is also very fragile against tearing when in contact with a sharp object. In this form it is not usable for protection.
Tools Pot Spoon or fork Stove Measuring scale Mold/sheet
Ingredients 20g Corn starch 20g Glycerine 10g Vinegar 80g Water
Method Mix the corn starch, glycerine and vinegar together and let it swell for a few minutes. Pour the water in the mix and heat it to approx. 90 degrees (Celcius) for 5-10 minutes. Once the mixture has thickened, cast it into a mold or plaster it over a glass/acrylic plate. Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the msterial. NOTE: when the material feels colder than the air temperature it means it's still drying.
Material properties
NOTE 1 Adding less glycerine will give a less flexible variant
NOTE 2 When trying to make a thicker sheet this mixture will tear while drying. The material will still have the same properties.
Conclusion The corn starch recipe has almost all the qualities I'd want in a foam pinda, only it is not suitable for thicker pieces. It is also more heavy than prevered.
Tools Pot Spoon or fork Stove Whisk Measuring scale Mold/sheet
Ingredients 20g Corn starch 10g Glycerine 10g Vinegar 20g Soap 80g Water
Method Mix the corn starch, glycerine and vinegar together and let it swell for a few minutes. Pour the water in the mix and heat it to approx. 90 degrees (Celcius) for 5-10 minutes. Once the mixture has thickened, add the soap and whisk it for another couple minutes until it has formed bubbles. Cast it into a mold or plaster it over a glass/acrylic plate. Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the material. NOTE: Unlike other starch recipes, this will not feel cold anymore after a couple hours.
Material properties
NOTE 01 This sheet has a small thickness, if you want to make a thicker sheet it is recommended to put the sheet in the freezer after casting. This will cool down the mixture more quickly and will prevent the lower layer from becoming set.
Conclusion This material is almost usable for foam pinda's, it's not thick enough and the weight is still a little too high. It is preverable for it's easy discard process, it will break down in warm water and go through the sink or you can throw it in the groenbak.

Ingredients 90ml Gelatine 30ml Glycerine 20ml Soap 120ml Water
Method Mix the gelatine and glycerine together and let it swell for a few minutes. Pour the water in the mix and heat it to approx. 90 degrees (Celcius) for 5-10 minutes. Once the mixture has thickened, add the soap and whisk it for another couple minutes until it has formed bubbles. Cast it into a mold or plaster it over a glass/acrylic plate. Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the material.
Material properties
NOTE 01 The material has a height of a couple mm's. The lower layer of the material has set back to it's properties before it was whisked. This can be prevented by storing the mixture in the freezer immediately after mixing or making a thinner sheet.
Conclusion The material properties of the top layer of the material are almost ideal. When executed better it might become perfect for a packing peanut.
Tools Bowl Mixer Measuring scale Mold/sheet
Ingredients 90ml Gelatine 30ml Glycerine 20ml Soap 120ml Water
Method Mix the gelatine and glycerine together and let it swell for a few minutes. Pour the water in the mixture and use a mixer for a few minutes. Stop once all the ingredients are completely mixed together. The mixture will turn into a grainy sticky material. The grains stick to each other but can be pulled apart.
Material properties
Further application
Shaping the material into small balls and heating them for 10 seconds in the microwave will make the material harder and less sticky to other surfaces.
Conclusion The material has the properties to protect an product but will also likely stick to the product. The material can be cleaned off of the product but that's not what you want a costumer to have to do. The heated version is still too unreliable to use.
Tools Pot Spoon or fork Stove Mixer Measuring scale Mold/sheet
Ingredients 100ml Gelatine 100ml Glycerine 50ml Honey +/- 5ml Soap 50ml Water
Method Mix the gelatine and water together and let it swell for a few minutes, and do the same to the honey and glycerine. Mix both mixtures together and heat it until the glyxerine has fully disolved. Add the soap to the mix and use a mixer for a few minutes. The mix is done when it starts to stick to the hooks of the mixer. Cast the mixture into a mold or glass plate and let it cool down in the freezer. Optional Honey does mold after a few days, to prevent this add +/- 5ml of an antibacterial to the mix.
Material properties
NOTE 01 Once the material has been mixed, it can be heated again without losing any 'foamness' and be recasted.
Conclusion This material is near perfect for packing peanuts. The gelatine foam sticks slightly to each other and might leave open spaces in boxes when shuffled (if it keeps sticking to each other). Apart from this, the material is very light in weight and will bend when pressed. It can be disposed of by disolving it in warm water or disposing of it in the groenbak.

Ingredients 20g Potato starch 20g Glycerine 10g Vinegar 80g Water
Method Mix the potato starch, glycerine and vinegar together and let it swell for a few minutes. Pour the water in the mix and heat it to approx. 90 degrees (Celcius) for 5-10 minutes. Once the mixture has thickened, cast it into a mold or plaster it over a glass/acrylic plate. Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the msterial. NOTE: when the material feels colder than the air temperature it means it's still drying.
Material properties
Conclusion This material is less flexible than the corn starch. It is too hard to use for packing peanuts and might scratch other products when used in transport.

Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the material. NOTE: Unlike other starch recipes, this will not feel cold anymore after a couple hours
Material properties
Conclusion The material completely shrank and dryed into small pieces. This might be prevented by making a thicker layer. - Unfit for packing peanuts -

Method Mix the potato starch, glycerine, vinegar and soap together and let it swell for a few minutes. Pour the water in the mixture and use a mixer for a few minutes. Stop once the mixture has risen to a foam like mixture and put it into the freezer.
NOTE 01 The material is strong and foam like when it's still at a freezing temperature, however when it heats up it will become fluid again.
Further application When you let it dry for a couple days it will turn into a thick snow like powder.
Material properties
Conclusion Very much usable for a packing peanut on Antartica. In europes climate? Not so much.

Ingredients 20g Tapioca starch 20g Glycerine 10g Vinegar 80g Water
Method Mix the tapioca starch, glycerine and vinegar together and let it swell for a few minutes. Pour the water in the mix and heat it to approx. 90 degrees (Celcius) for 5-10 minutes. Once the mixture has thickened, cast it into a mold or plaster it over a glass/acrylic plate. Let it dry for a few days before taking it out and when needed stick it down to prevent bending of the msterial. NOTE: when the material feels colder than the air temperature it means it's still drying.
Material properties
Conclusion Tapioca is the most hard of all the starch recipes. It is not usable for packing peanuts because it might damage the products while in transport.

“The current trend in new materials in design is booming. It is no longer enough to create functional, beautiful or high-tech stuff. We need to shake off our plastic addiction and look differently at the kind of production materials we use as designers. In most material archives, an open-source ethic is lacking, material innovations are often patented and only sold within business-2-business. Our natural recourses are part of the commons, we should have material knowledge to match it.”
I want to continue finding a more sustainable solution to packing peanuts. Packing peanuts are mainly made from plastics and are very rarely made from different materials. They are made from styrofoam and the peanuts are not recyclable. I want to see if I can make packing peanuts from bioplastics.
Packing peanuts are a loose-fill packaging and cushioning object used during transportation. Packing peanuts get their name from the resemblance in shape and size of a peanut. The packing peanuts protect products against breakage. They can be reused many times with little to no loss in protection for the products shipped. Packing peanuts are favorable because of their very light weight.They were made in the 60's and used frequently during the first few decades, but the use of packing peanuts declined since the 90's because of their enviromental impact.
Today they are mostly used for heavy or very fragile products, when substitutes will not guarantee the same amount of protection.
Packing peanuts are originally made from polystyrene resin. When they were first developed it was made from 100% virgin polystyrene, since the mid-90's recycled polystyrene packing peanuts have also been available. In later years there have also been cornstarch based packing peanuts. These packing peanuts have the same look and feel as polystyrene resin packing peanuts but are more expensive because of the higher weight and manufacturing costs.
There are three color variations of packing peanuts: white, green and pink. The colors of the packing peanuts indicate what material they are made from. White packing peanuts are made from 100% virgin polystyrene resin, green packing peanuts are made from 70% or more recycled polystyrene resin and pink packing peanuts indicates a antistatic agent has been used in the peanuts (An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static electricity).
I want to make a more sustainable solution to packing peanuts. The peanuts will be more sustainable by using renewable and recyclable materials.
The packing peanuts will protect any object against breakage.
The packing peanuts will be made from renewable materials in bioplastic.
The packing peanuts will not grow mold.
The packing peanuts will be reusable.
Waarom is die onderste niet ook een presentatie ? Ja geen idee, ik snap Heel weinig van technologie .
The packing peanuts will be as close to normal packing peanuts weight as possible (usually around 30 grams per litre)
The packing peanuts will be flexible.
The packing peanuts will be water resistant.
The peanuts will be heat resistant for heat under 45 degrees.
