Stage 1

• created to make cleaning easier
• manufactured my 3M or MMM

1. Minnesota Mining and Manufacturing

• design inspired by sea sponges
• patented by the Du Pont company-1940

Stage 2

Raw Materials aquired are

• Cellulose-from Wood Pulp
• Sodium Sulphate-common chemical
• Hemp Fiber- A plant

2

• cellulose fiber

1. made of wood pulp

2. pressed into large, stiff sheets

3. soaked in water and fabric softeners

Stage 4

There are five steps in the Manufacturing process.

• Cellulose is soaked in water and mixed with chemicals to make it soft.
• Mixed in a empty barrel which includes sodium sulphate crystals and hemp fibers.
• Mix is then spilled in molds and cooked.
• Sodim Sulphate crystals drain away, leave holes in sponge and mix , when it cools, becomes hard.
• Soaked in bleach, cleaned, and softened with water.
• Sponge blocks cut to small size and finally packaged.

Stage 5

• packages of 1,2,3,4,6,9
• plastic packaging

1. rarely recycled

2. decomposes slowly

3. harmful to the environment

Stage 6

Sponge shipping

• compacted with hydralic presses and tied together to save the transportation cost.
• compacted sponges kept in warehouse to get ready for shipping.

Stage 7

• used to wash dishes-pots and pans

• according to reviews, "it lasts a long time"

7

Stage 8

• It will not contaminate water if disposed of.
