This study aims to aid the public utility jeepneys in the Philippines to lessen its carbon
emission that harms the ozone layer. In order to provide a simple and affordable solution
for this, the Exhaust Smoke Filter using mussel shells was created. Utilizing affordable
materials such as “Tahong” or Perna Vidis, sheet metal, and wire mesh, the project can be
made by anyone who is able to reproduce it. The design follows a simple three cylinders
that are different in sizes and welded together. With the outer end holding the mussel shell
in place inside a wire mesh cage and the center part holding a Titanium Monolith, then the
smaller cylinder acting as the connecting point of the exhaust pipe and the Exhaust Smoke
Filter using mussel shells, anyone can install it with ease. The mussel shell acts as the
filtrate that absorbs the excess burned gasses that in most cases, goes unfiltered once
ejected from the catalytic converter. This causes the harmful gases to freely enter the
atmosphere and accumulate within the ozone layer. The evaluation process was based on
the following: functionality, durability, safety, economy, and workability. The study
suggests that the project should undergo professional testing to provide better results.
