Science Buddies: "Ask an Expert"

We came up with a study involving usage of shrimp shells as an alternative ingredient in manufacturing whiteboards on behalf of our research subject. We found out that shrimp shells contained chitin which is also found in whiteboards. Furthermore, calcium carbonate can be observed in both the shells and the board's surface. In the end, we were convinced that we could utilize shrimp shells as a main component of whiteboard paint since it is comparable with the materials used in conventional whiteboards.

We wish to inquire on what procedure would be most effective in carrying out our study and the possible factors that we may or may not consider in our process. In addition, we would also like to know whether our procedure should be, or at least almost, identical to the conventional process of making whiteboards. Otherwise, please feel free to express ideas that could be considered in our research. Any suggestion is welcomed and appreciated. Thank you.

Hi jericho985,

Paint may contain a refined and high purity calcium carbonate as a pigment or filler. Calcium carbonate is a component of shrimp shells but I don't think the shells could be used as a direct replacement for calcium carbonate in a paint formulation. Rather, it might be necessary to separate the calcium carbonate from the organic material in the shells.

Some whiteboards might have a cardboard or fiberboard substrate. Either of these materials may include an inorganic filler. And it might be feasible to include shrimp shells in the filler.

My suggestion for additional research is to look into the manufacture of whiteboard and its components. This may reveal some additional information about how shrimp shells might need to be processed for inclusion.

I hope this helps. Please ask again if you have more questions.
