In accordance with waste management measures set by the US Environmental Protection Agency (USEPA) in the 1970s, a robust cleaner production approach was proposed in the 1980s to develop an encompassing strategy which focuses more on waste minimization, pollution control, and recycling of materials [26, 27].
As industrial production processes increase in the area of energy generation and conversion of raw materials, considerable efforts must be put in place to eliminate poisonous raw materials and reduce the level of pollutant emissions which are bound to leave the processes.
Microbes like bacteria, yeasts and microalgae are known to have the ability of stockpile lipids and oils originating from these microbes are promising raw materials for biodiesel production [33 – 39].

AlN has especially attractive characteristics as a new functional material, but it is difficult to densify due to its strong covalent bonding.
Many research studies on liquid phase sintering, the fabrication process, characterization and evaluation and application development have been conducted by numerous researchers and engineers.
New materials innovation by the sintering of AlN with additives Innovation of sintering aids for AlN densification.
■ The first key innovation was the discovery of critical sintering aids for AlN densification, namely rare-earth compounds and alkali-earth compounds, especially Y2O3 and CaO
