This paper aims to present the advances related to the biotechnological application of lipases Y. lipolytica, presenting their properties and more efficient ways to use them in different industrial applications. Waste treatment and bioremediation highlight recent studies and advances and the interest in large-scale applications in the food sector and biofuel production. The USA and China, two major world powers in industy, are of utmost importance in the search for the improvement in the development and properties of a controlled system for the large-scale production of a significant number of applications of lipase from Y. lipolytica.

The use of coal as fuel in various industrial processes such as thermoelectric and steel mills generates relevant amounts of waste or by-products, called coal combustion product (CCP’s). Therefore, viable alternatives for the correct disposal or technological applications of this by-product are studied with or without the addition of reinforcement phases in order to reduce the environmental impacts caused. Among these applications, one possible approach is the use of CCP’s for the manufacture of ceramic tiles, since these residues are chemically similar to several ceramics. Therefore, this work aimed to evaluate some physical and mechanical properties of CCP’s to observe the feasibility of manufacturing ceramic parts for coating from the product of coal combustion. The results confirmed the potential and feasibility of using CCP’s to completely compose the ceramic tiles matrix.
