As such, using the information gathered, Table 1 below Methodology
summarises the costs involved: The soap cubes are melted into a liquid form in a mould to
incorporate the burnt charcoal ash into the soap base. This
combination is subsequently left to cool down to allow it to
harden in the mould and revert to its original solid state. The
whole process is illustrated by Figures 8 to 11 below.

Eco-Solution Prototype
Buoyed by the promising research findings and correlation
between activated charcoal's adsorption properties and burnt
charcoal ash, the team set out to innovate a cleaning product
that incorporates burnt charcoal ash that could potentially
help the company save costs on commercial cleaning products
and water costs while embracing sustainability. Figure 8: Heating solid soap Figure 9: Reshaping liquid soap
cubes into liquid form infused with charcoal ashes
The base material for the eco-solution is glycerin soap base
made of natural ingredients, as seen in Figure 7:
