THIRD GENERATION PSMELTING
UNIT - DEVELOPED
PPCP continues its advocacy in recycling. In order
to address the perceived concerns of some quarters
regarding the alleged environmental effects of PS
melting oven, PPCP in cooperation with the Department
of Science and Technology - Material Science Division
has developed a newly improved third Generation of
melting oven for foam polystyrene.
After a thorough research finally, the PPCP - DOST
has launched its newly improved PS melting unit. Enhancement
of its features made it easier for the recycling of
foam polystyrene. During the development, comprehensive
assessment on its environmental impact was done which
includes a careful examination on its smoke emission
and odor reaction mechanism. With a satisfactory result
gained from the gas emission test conducted together
with the DOST - MSD - ITDI experts and the Ateneo
National Chemistry Instrumentation Division, this
third generation melting unit had passed the alleged
non-environmental issues.

A CLOSER LOOK ON ITS
IMPROVEMENTS
The earlier generations of PS melting oven are made
up of steel vessel, metal lined, with cover, LPG fired
– 50 kgs capacity with downspout for pouring
molten products with hood and chimney for smoke.
Now, melting process has been made easier and simplified.
An improved paddle for mixing the foam PS has been
attached to the unit. Gas emission has been more manageable
through the enhanced exhaust chimney, suction blower,
a condenser for liquid gas collection, hooper, activated
charcoal chamber, motorized plunger, vacuum pump for
gas collection and melting chamber cover.These enhanced
features of third generation PS melting oven produces
a cleaner gas emission.
The improved unit is also composed of an improved
temperature recorder from the previous contemporary
temperature gauge of second generation melting unit
which gives accuracy in the heating process and the
over-all outcome of the end product. Improved spout
is attached for better pouring and casting on pre-shaped
metal moulds.

MORE USEFUL PRODUCTS
Some useful products are table tops, cat walk, boards,
bricks, synthetic timber plank and now even plastic
planters are being discovered from the recycled foam
PS.

GROWING PUBLIC INTEREST
With the continuous effort of the organization, PPCP
believes that this technology will not only help regularize
recycling industry but safeguard the environment while
at the same time providing an option for diversion
of solid wastes.
Demand from the LGU's and communities are relatively
good. PPCP's main objective is to promote recycling
using this technology with the benefit of generating
income at the side. Trainings and actual demonstrations
were conducted to municipalities of different regions
and cities like in Cebu, Lapu-Lapu and Boracay. PPCP
was even able to conduct such actual demonstrations
in schools that embrace Solid Waste Management in
their premises like the Environmental Science Institute
of Miriam College.
More and more innovations for recycling will hopefully
come out as PPCP continues in performing its mission
on providing more campaigns and information on recycling
to help and protect the environment.
