Making Bio-Plastics at home – Coffee

 

This recipe tells you how to make bio-plastic using ground coffee and other ingredients in your kitchen cupboards – a lockdown recipe.

Step by step method:

1. Add 50g cornflour to a bowl
2. Then add 150ml water,
3. 25g dry ground coffee – you can use ,
4. 5ml white wine vinegar,
5. 5ml lemon juice,
6. 2g sodium bicarb,
7. 5ml Rapeseed oil
8. Stir over heat until mixture turns into a dough
9. Let cool down then mould into a shape 
10. Bake for 35 mins at 180 degrees
11. Let cool

As you can see from my photos above of the finished bowl, after being baked the material is quite brittle therefore cracks and breaks quite easily. I’d recommend making a simple shape out of this material and you could also try adding glycerol or glycerine to make the texture more plastic-like. I’ve also added more water to this recipe as I think it would make the outcome less dry. This material is solid and waterproof to an extent.
