| Abstract: | An attempt has been made to encapsulate heavy metals and dyes present in textile sludge using low density polyethylene
(LDPE) and assess usability of encapsulated product for building construction. Sludge samples were encapsulated into LDPE
with calcium oxide (additive) at four different proportions (35, 40, 50 and 60 %) of sludge. Encapsulated cubes were formed
and then tested for compressive strength. Maximum compressive strength of cubes (size, 7.06 cm) containing sludge (50%) for
sample 1 (21.07 N/mm²) and sample 2 (17.55 N/mm²) was more than that of standard M15 mortar cubes. Encapsulated product
could be recommended for use in the construction of non-load bearing walls. TCLP study revealed that leaching of dyes and
heavy metals (Cu, Ni, Pb and Cr) has been effectively reduced after encapsulation process. |
