|Title:||A study on polyethylene microencapsulation of textile sludge|
|Authors:||Raji, R Jeevitha|
|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.|
