1. USED PLASTIC BOTTLES
AND CAPS AS BRICKS
Group 6

2. Our project converts used
plastic bottles and caps into
alternative materials,
specifically bricks for
temporary and permanent
evacuation houses, shelters,
classrooms, community
rooms and other buildings. It doesn't only
prevents pollution
generated by plastic
wastes, it is also about
how challenges are
turned into puzzle
pieces and building
blocks for the future of
the children and the
Bricks that are
durable and easy-
to-assemble will
be used to build
much needed
construction
materials with
minimal training.

3. Introduction
Introduction
Plastic pollution is a major problem in the Philippines, which – along with China,
Vietnam and Indonesia – is frequently listed among the world's worst offenders,
particularly on marine plastic pollution (Rappler.com, 2019). According to the United
Nations report, Philippines is 1 of 5 countries that produce half of world's plastic waste.
Plastic is a non-bio-degradable substance which takes thousands of years to decompose
that creates land and water pollution.
Polyethylene terephthalate or PET bottles (the second most common type of plastic
found in the environment) are one of the most valuable forms of plastic in the
Philippines and the most retrieved due to its high residual value. PET bottles are
commonly used in food and beverage packaging.
According to National Geographic News (2014), the increasing number of buildings
collapsing while under construction or soon after has reached alarming proportions and
something urgently needs to be done. For 3 years alone, news reports of buildings
collapsing due to substandard building materials claimed lives of more than 1100 people
across Africa and Asia.
Bricks are construction materials used in all the constructions: residential,
commercial and industrial building constructions for brick walls, foundations, pillars and
