The objectives of this research are 1) to study the utilization of waste materials type the ceramic tile
and 2) to develop community products from waste materials type the ceramic tile. The ceramic materials
used in this research are granite tile fragments (after burning). The object of this case study is Kenzai Ceramics
Industry Co., Ltd. In this study, the researcher used such waste ceramic fragments to study how to shape it
by using 3 processes based on material engineering theory on composite ceramic materials. The results of
the study revealed that the utilization process which could be used to develop granite tiles fragments (after
burning) to be composite ceramic materials with good physical and mechanical properties was the third
process: perforate ceramic molding process. The most suitable formulation was PCB5 (the ratio of waste
material, cement and pure water was 50:50:15) with compressive strength of 78.07 MPa. Based on evaluation
results from three material science experts, the third process was the most appropriate one (  = 4.56,
S.D. = 0.41). By analysis result of community products with were most suitable and consistent to the third
process, the most suitable and consistent one was concrete flooring block products. Such product was
durable and resistant to abrasion and shock with high porosity. As a result, such concrete blocks made of
ceramics waste material was significantly less weight than the old product. By the study of the utilization
process and community products made of ceramic waste material, it was found that Interlocking concrete
paving blocks products could reduce the amount of granite tile fragments (after burning) well from 57.25
tons (per month) to 48.60 tons (per month). Month), to say it was 8.65 tons (per month) reduced, and could
reduce the amount of overall waste in the ceramic tile industry from 158.25 tons per month to about 149.60
tons per month. It could be concluded that the third process which uses granite tile fragments (after burning)
as the main material could reduce the amount of waste type the ceramic tile. It could also be applied in the
development of Interlocking concrete paving blocks products with better physical and mechanical properties.
