“…BW sample investigated in the dry state do not show a step of water loss, but the first visible step of mass loss were between 200°C -260°C, which represent the loss of functional groups (-OH; -CHO; -CH 3 OH) from the structural components: lignin, cellulose, hemicellulose. In order to emphasise the rate and temperature of thermal degradation for the raw materials, Table 5 summarizes the temperature corresponding to the following mass loss: 5%, 10%, and 25% together with the final residue at 1050°C (Petreanu et al, 2012). The order of mass loss for raw materials used in the development mixtures, was the following: Slag/Bottom ash> Lignite> BW > MBM.…”

The efficient use of renewable energy resources is one of the most important elements of energy sustainability at the European Union level. The growing demand for energy will continue to support the use of other materials as resources of energy than conventional ones, coal, crude oil and natural gas. This paper investigates the feasibility of valorizing wastes with energetic potential in a multi-component alternative solid fuel. Biomass - vegetable waste (BW), meat and bone meal (MBM) and slag/bottom ash from lignite combustion, in combination with a low-rank, lignite, was used to prepare tri-component mixtures (MBM+Lignite +Slag and MBM+BW+Lignite) indifferent variable proportions, and further characterized to assess their potential for use as energy source. The thermal behavior of the mixtures was assessed by thermogravimetric analysis; the resulting ashes were characterized by scanning electron microscopy.Also, the environmental impact as emissions level after their combustion was considered. In terms of an effective way of removing wastes (e.g. slag/bottom ash and MBM), the most promising proposed solid mixture was the combination MBM(50%): Lignite(25%): Slag (25%), with a high energetic value, > 2700 kcal/kg, a volatile matter content > 35 %wt, and the ash in half amount compared to its initial mass. Thestudy’s findings illustrate the possibility of turning solid waste to raw material by converting them into energy, and promote the development of long-term waste management and recovery solutions.

“…Also, EW is defined as mass of dried polymers (g) per number of sulfonic acid groups. The hydration degree of electrolyte polymer is often described as the number of water molecules per fixed ionic group (HSO À 3 ) [37]. The value of proton conductivity of PEM is determined through potentiostatic measurement of PEM resistivity, either ex situ only for polymer electrolyte film, or in situ, in the MEA or in the PEMFC.…”
