F.II. Perspectives

Considering the continuing sensibilisation to environment problems, the measures to minimize the impact of above mentioned implications should be taken into consideration before starting a small-scale soap-making business.

In this purpose measures for waste waters depollution and optimized use from energy sources may be done by planing. Installing a biogas plant in place of classical septic tanks could be for instance a great contribution. The produced biogas is usable as combustible and can efficiently replace the wood or wood charcoal.

Moreover in some climate areas, where external temperatures and the number of yearly sunny days are bright, efforts of research action are to be made for the design of a saponification method using sun as a source of energy. In fact the temperature of 35 - 55 °C necessary for the starting of saponification according to the cold and semi-ho/methods could be reached in appropriate boilers exposed to the sun rays in these zones.

Efforts of research-action for the mastering of such method and the achievement of a simple and efficient mixing system are well indicated.
