REASON

The reason for asking this is we've done that a million times and everytime the result was the same: 

• We need to find new ideas to reduce plastic pollution. 
• The overuse of plastic worldwide, potentially harmfull for the environment calls for urgent measures. 
• Consider, for exemple, raw material. This can include fossil fuels, industrial minerals, stones, earths and construction minerals. 
• Wood or natural fibers and all organic substances of non-fossil origin fall under the umbrella term of renewable raw material.
