his research explored the potential use biowaste cellulosic fibers as drywall panel board (DB) as construction material.
The cellulosic fiber used in this study were primarily extracted from rice and banana crops agro-wastes which are highly
cultivated in Philippines, other wastes used came from paper and carton boards. These biowaste products contribute to the
environmental and climate change problems but can be mitigated by converting these wastes for productive reuse. In this
experiment, the thermal conductivity (k value) and thermal resistivity (R-value) were determined. The materials tested were
plaster of Paris as binder and perlite powder as fillers with respect to plaster/perlite/fiber ratio using percentage by weight, there
were six (6) formulations used in the study, namely plaster of Paris (P-1), plaster of Paris and perlite (P-2), waste paper and rice
straw (WR), waste paper and banana fiber (WB), rice straw and banana fiber (RB) and waste paper, rice straw and banana fiber
(WRB). The R-following values were obtained for each formulation during testing: P-1 (0.36 h-ft2-°F/BTU), P-2 (0.49 h-ft2-°F/
BTU), WR (0.83 h-ft2-°F/BTU), WB (0.67 h-ft2-°F/BTU), RB (0.88 h-ft2-°F/BTU), and WRB (0.68 h-ft2-°F/BTU). Moisture
and water absorption were also determined. Among six (6) formulations, RB showed significant results having an R value of
0.88 h-ft2-°F/BTU when compared with commercially available drywall boards. The common drywall boards in the market
have the following R-values: fiber-cement board (0.19 h-ft2-°F/BTU), hardboard (0.69 h-ft2-°F/BTU), ordinary plywood (0.62
h-ft2- °F/BTU), medium-density particle board (0.52 h-ft2-°F/BTU) and gypsum wallboard (0.45 h-ft2-°F/BTU). In theory,
a higher R-value means that the material can lower the amount of heat gain inside the room. Hence, the material is energy
efficient. Moreover, properties of the material such as acoustical capacity, fire resistivity and water absorption can be further
explored.
Biography
Jean Marie Villmaor-Junaga is a Professor at the Department of Architecture at the University of the Philippines and is also a practicing Architect since 20
years. She has been actively attending international conferences on research related to housing, planning and material development. She has also made recent
publications at the
International Journal of Architecture and Urban Development
(IJAUD) on vertical farming. Currently, she is more into researches related to
material development of agricultural wastes in order to maximize potential use of waste while at the same time support waste valorization for a more sustainable
and healthy environment.
