| Abstract | This study aimed to make use of paper mill cake by converting it into a disposable bin. In
addition, properties of all materials used as well as the bin itself were evaluated in terms of
bin forming material and its negative impacts on the environment. Sludge cake should be
prepared in a slurry form to further develop into a sheet of bin. This slurry however needed
a supporting material as well as a binder. From the experiments showed that the candidate
for materials selected to be used were cloth and latex in saturated condition. The criteria on
sheet (bin) development are based on its maximum tensile stress, weight, thickness and
water absorption. This is because it is anticipated treat the bin can be used anywhere in the
industry even in the toilet or bathroom. The inferior points of this already made sheet
included dried very slowly, not uniform thickness, odor problem and difficult to control
uniform shape due to active shrinkage of fibers whenever rapid evaporation from slurry
occurred. Control on sheet preparation such as drying process is recommended. Thus it
needs further study to develop technique for improving its quality in the future. The sheet
that had been made from this study may have other applications besides making the
disposable bin. For outdoors' activities, this sheet can be used to make the shading roof for
the orchid farm or container for small plants. Finally, from the result of toxicity tests
(leaching and germination) show that the tendency to dispose it to landfill is possible due
to its safety level of lead, nickel and copper and also not to cause plant toxicity but tend to
seedling growth. Furthermore, the bin can serve as soil conditioner by improving soil
porosity and texture through introduction of biodegradable material to soil. Thus, organic
carbon content added and soil microbial activity increased can be expected when the
material is disposal to the soil. |
