Rationale additives for construction materials and handicrafts.


Philippines is a vast archipelago surrounded by water. Not only it is rich in
aquatic treasure, but also a haven for people who indulge in seafood (Wrye83
2017). Filipinos only eat the meat of the seafood and throw the shells away,
believing that it has no use which can lead to pollution. Throwing away
crustacean shells can cause harm in our surroundings if not properly disposed
of, but if these shells will be collected and recycled, water pollution may be
reduced thus the environment may be protected. There have been several efforts
to recycle sea shells such as making them as additives for construction materials
and handicrafts.

The researchers thought of finding another way to
recycle sea shells, shrimp shells in particular. It was found out that shrimp
shells are made up of polyurethane paint. This is used in making whiteboards,
because it makes the board a “dry erase” pad best paired with a “dry erase”
marker (Acosta 2017). The researchers aim to use shrimp shells to produce a
whiteboard paint. The whiteboard will be more affordable yet has the potential
to have the same quality as the commercial one.

Numerous schools in rural places and some urban
areas are lacking school supplies –especially writing boards that function as a
teaching aid for students and teachers (Weinstein 2010).

            Whiteboard is becoming every
classroom’s necessity in the Philippines in spite of its expensive price.
Unlike blackboards, whiteboards can not cause any disease that includes lungs,
for an example, asthma. Blackboards can cause irritation to our nose and might
rigger breathing diseases to people who have these.

            The polyurethane’s long
decomposition time could cause and even increase pollution in our surroundings.
The best way to avoid contributing to it would be utilizing eco-friendly
materials in manufacturing whiteboards by replacing the plastic material with a
waste one, particularly shrimp shells. Moreover, this would benefit the tight
budgets for education since dry erase paint are normally expensive, while
shrimp shells can easily be found anywhere. Because the production of a
whiteboard with a waste material is cheaper and convenient, the government,
private insitutions, and other personalities may have the ability to afford
these boards that could be distributed and function as a teaching aid for
schools, offices, and homes everywhere

This study aims to determine if shrimp shells can be
an effective ingredient in making dry erase whiteboard paint. In addition, this
study intends to help schools nationwide by providing quality whiteboards and
help in lessening the effects of pollution in the environment.

Research Questions

          The study will focus on the
production of whiteboards out of shrimp shells. It aims to answer

following questions:

           1.Can shrimp shells be used as
alternative materials for resin and extended paper in


           2. Is there no significant
difference between whiteboards made out of shrimp shells and

whiteboard in terms of:

          2.1. the texture of the surface?

          2.2. durability?

          2.3. how easy it is to write on the

          2.4. how easy the writings on the
board can be erased?

          2.5. price?

5 kg of Crustacean Shells

35 cm x 5 cm x 3 cm of wood board

35 cm x 5 cm x 3 cm of aluminum frame

100ml Titanium Oxide

25ml Thickener



10ml Defoamer

Paint roller

Clean sponge

3m Painter’s tape

Metal rod or mixing machine


            Five kilograms of crustacean shells
will be washed and will be sundried for 2 weeks. The shells will be collected
and grinded with mortar and pestle. One hundred milliliters of water and 100 ml
titanium dioxide will be poured together in a beaker. Titanium dioxide would
function as the white pigment for the whiteboard. Twenty-five milliliters
thickener will be added to the mixture afterwards. It will improve the paint’s smoothness
and let it flow with ease during application it with a brush or any painting
materials without affecting the other properties of the paint itself. The powdered
crustacean shells will be added to the solution which will enhance the texture
and other characteristics of it. Thus, making it a fit replacement for the two
conventional components of whiteboard- the resin and extender paper. The 10 ml
defoamer will be put in the mixture to lessen the bubbles appearing on the
surface of the paint. The prepared mixture with a metal rod or a mixing machine
will be stirred.


Ø  Constructing
the Whiteboard

for the wood board the, it is important to keep it clean before smearing the
paint on it to avoid any noticeable marks during the painting process. A clean
sponge will be rubbed against the board to remove unnecessary dusts or dirt. When
the board is clean, adhesion of the painter’s tape will take place on all the
sides of the board. This would help the researchers determine the limits for
painting the prepared mixture on the board’s surface. When the tape is securely
applied, the the board will be painted
using a roller. The spreading should be even, not thin not too thick.

finished, the board will be placed in an area where it could be reached by
sunlight. The board will be dried for 48 hours or more if necessary. When the
paint has completely dried off, the researchers will then case the edges and
corners of the made whiteboard with the aluminum frame.

Data Analysis

the researchers will need to test its durability, texture in accordance to the

of the researcher. A survey will be conducted by the researchers to determine
the durability

the whiteboard.

Risk and Safety

            The possible risk that the
researcher may be encountered during the process are the possible harm that may
be inflicted if proper precautionary measures are not observed. To ensure
safety during the process, keep this in mind. Wear appropriate protective
equipment when handling any materials that are used in this process, do not
sniff fumes that may be exerted during the process and keep any heat, light,
ignition sources and sparks away.

            The possible dangers that may happen
to you during this process is that it can cause severe irritation, redness, tearing,
or blurred vision as well as corneal opacity and conjunctivitis. It causes
irritation, defatting dermatitis, and sensitization by skin contact. It can
cause gastrointestinal irritation, nausea, vomiting, diarrhea and aspiration of
material into the lungs.
