Food packaging is a significant source of "raw" material for recycling crafts, and when you use it as a mold,
your imagination is the only limit to what you can make. Here is a mortar soap dish made from a hamburger patty container.
Collect plastic hamburger patty trays. Rinse.
Make lime mortar or eco-friendly cement.
lime mortar: Mix 1 part cement* and 1 part lime in 1 part water.
eco-friendly cement: Mix 3 parts river sand, 3 parts sawdust, 1 part cement*, 1 part lime, and enough water to make a supple mortar.
Sprinkle the powders in water and stir with a wooden stick. Fill the molds with a spatula and let dry 24 hours.
Remove the soap dishes from the molds by cutting the plastic tray with scissors or a knife.
Extend the indentations to allow water to run off, using a pointed tool such as a gimlet, screwdriver or drill bit.
Scratch hard. The cement and lime mixture is relatively easy to sculpt.
* cement: Despite efforts made by manufacturers, cement production is still energy- and CO2-intensive.
For the time being, the only effective alternative in the area of home decoration or renovation
is to use the smallest possible amount of cement in mortars and plaster.
