The way we obtain our energy occupies an important place within the efforts to reduce pollution and climate changes. Currently, our energy still comes mainly from fossil fuels, which release greenhouse gases when they are combusted to produce energy. Due to the inevitable depletion of fossil fuels and the increased energy requirements caused by the rapid growth of the population in the last fifty years, it was necessary to find alternative sources of energy. One of the most important alternative sources of energy is biomass (wood, straws, sawdust, husk, branches, etc.). Biomass pelleting has become one of the most important ways to use biomass as a replacement for fossil fuels in the view of reducing greenhouse gas emissions and pollution in general. The paper presents experimental researches conducted on the process of compacting various types of biomass, in the form of pellets, following the influence of biomass recipes used on the final quality of pellets. The physical and thermal parameters of pellets are influenced by the use of different binding agents or additives (corn starch) in the manufacturing process. Recipe changes can lead to increased productions, reduced energy requirements per product unit and also to an improved quality (in terms of calorific value, durability, density, etc.). When used in combination with different types of biomass materials, each additive and binder leads to unique physical and thermal characteristics. Starch has proven to be a good additive in pellet production [1; 2]. Thus, is important to conduct researches to identify the mixtures of biomass and additives that produce pellets with the desired physical and thermal characteristics, to maintain pellets competitive as an option for renewable energy. The results of this paper contribute to achieving efficient and eco-friendly biofuel, leading to a sustainable development and cleaner environment.
