easibility study of
in situ
PCC synthesis technology for paper recycling in the Phong Khe Paper Craft Village of Vietnam
has a green manufacture model and solution for environmental remediation.
In situ
PCC synthesis technology is a recycling
technique of waste paper and capture and direct utilization of low concentration of CO
2
with PCC filler which improves
whiteness and machinery lifetime of paper. This paper recycling with
in situ
PCC synthesis has been developed and popularized
in other countries. It is featured by a process of mixing waste pulp with PCC formed by quick lime (CaO) and CO
2
in an in situ
PCC Reactor. In general, PCC synthesis processes are divided into the two following steps in paper recycling process: (1) CaO
is turned into slaked lime (calcium hydroxide, Ca(OH)
2
) through its reaction with water, which is called hydraulic process and
(2) PCC is synthesized by the reaction between Ca(OH)
2
and carbonate ions (CO
3
2-
). The technology has several advantages.
It reduces overall manufacture costs and needs fewer corrosive chemicals, thus extending machinery lifetime. Most of all, the
process is more environmentally friendly due to following reasons: Easier recycling CO
2
generated from paper industry, wood
consumption reduction, less wastewater and byproduct production from the process and less energy consumption owing to
shorter refining and drying times. It is calculated that recycling one ton of waste paper can reduce 937 kg CO
2
, 3.22 KWh
energy, 42,465 L water and 340 kg waste. In order to apply the paper recycling technology, an action plan which collects waste
papers is required as a climate change adaptation. To spread the collection of waste papers, the system which transfers the
collected waste papers to cashable mileage needs to be introduced in Phong Khe village and extend to entire of Vietnam. The
system needs to be started with students and citizens as an education to sustainable paper recycling.
