The present study was dedicated to introducing the agri-food residual biomass potential evaluated from the model calculation and for considering all possibilities of its utilization for heat and/or energy production. <br />Emphasis has been given to the agricultural and food industry wastes, as well as animal organic wastes, aimed to follow some technology tendency for performing a proper treatment of a mixture prepared from these organic wastes, in order to reach as much as possible biogas (bio-methane as a holder of bioenergy).<br />The most important way to reduce carbon emission is strongly depended firstly on how much local potential of each source can be collected and there is a number of factors such as the quality of waste chosen as a feedstock, conversion route, processing technology, its maturity and possibility to improve the efficiency of transformation into a bio-source of energy.<br />For this work has been chosen the biodegradation, but there are also other methods of preliminary waste treatment for disintegration such as composting or burning which however does not resolve definitely the issues related to the collection of such organic wastes, because from them still remains some residue after treatments. <br />For this study, it was performed a series of different transformation methods for agri-food and animal organic residues, as well as their combinations, so-called pretreatment process, which prepare conditions so the biomass to undergo to an easier process for anaerobic bio digestion or them. During these processes especially for the former one, play a key role some kind of specialized microorganisms which can produce a mixture of gases (Biogas composed of 65% methane and 35% carbon dioxide) and a mixture of liquid (which carries a high value of mineral nutrient elements like nitrogen, phosphorus, especially used as fertilizer additive, etc.

Cement technology is very traditional and the basic principles have remained unchanged for a long time. However, very profound changes in the production techniques were introduced recently, leading to the diminishing of energy consumption. <br />Energy cost has affected manufactures to evaluate the substitution of conventional fuels with alternative fuels, i.e. processed waste. To be able to use alternative fuels as; waste oils, plastics, waste tire, sewage sludge, etc. it is necessary to know the composition of these alternative materials. So, the usage of waste organic materials affects the thermal energy in the heated furnace. It was used as an example of applying the results of this study in a cement production plant in Albania, which has started a strategy for the real studies allowing to use other alternative fuels. <br />In this study was used Aspen Plus simulation software to test the possibility for improving the energy performance of cement clinker burning oven process, while maintaining the same product quality. <br />For this purpose, were used data from real production practice. Mixtures of various organic materials were tested with Aspen Plus simulation software. <br />The results of different alternative material were compared with conventional materials such as oil, diesel, heavy oil, gas, etc. On the other hand, from the simulation results, it was identified as the most effective fuel source to minimize the material and energy cost.
