Magnetic materials with low coercivity of the order of 12.5 Oe are termed as soft and those with coercivity above 12.5 Oe are called hard magnetic materials.
This is more beneficial for the formation of uniform colloidal materials.

The efficiency of these developed materials, however, is still low at present.
Nevertheless, the catalytic activity of PTA mainly depends on the type of support materials.
Low interaction between PTA and support materials will result in the difficulty of loading[4].

The problem is that the waste consists of mostly non-recyclable materials.
Therefore, non-recyclable and difficult-to-recycle materials have to be replaced with environmental friendly materials.
Efforts in substituting non-recyclable materials with recyclable materials have been performed throughout the world.

The properties of the alternative building wall materials are identified and compared with that of conventional bricks.
Availability of alternative building materials.
The materials were properly weathered and their properties were studied with the help of literature reviews (Annexure-I).
Additionally, the block is produced using locally available materials and resources, and is therefore socio-economically feasible.
