“…The set of briquettes was assessed to apparent density (ρ), relaxed density (ρ tw ), relaxation (ε tw ), hygroscopicity (H), HHV, potential (E P ) and real (E R ) energy density, and loss of energy density (L E ), as the methods adapted from Lu et al [29], Avelar et al [30], Nakashima et al [31] and Mendoza Martinez et al [27].…”

The re-use of glycerol from biodiesel industry as an alternative lubricant for making high-performance briquettes is usual. However, the technical performance of this agro-industrial residue is not consistent. This study outlines, accordingly, the real risk of introducing glycerol into the co-briquetting of highly caloric by-products of energy-crops. The production of hybrid briquettes consisted of pressing mixtures of residues of sugarcane and sorghum with the liquid additive at 10, 20, and 30 wt.% in bench-scale hydraulic piston presser machine. Irrespective of the blend, briquettes containing the supplement at the highest level as part of their composition ended up being much more hygroscopic (20.10%) and less energetic (3.15 GJ m −3). The explanation for the negative impact of glycerol on the thermomechanical behavior of briquettes would be overconcentration of additive capable of effectively defying compacting biomass. The degree of compaction during co-briquetting has likely gone down quickly with a maximizing level of glycerol. As long as the additive is not able to lubricate the feedstock suitably, improbability of biomass particles to successfully bond together to form themselves into mechanically stable and energetically effective briquettes is large. Besides lower density (273.80 kg m −3) and higher relaxation (22.75%), briquettes with glycerol at 30 wt.% generally were aesthetically unpleasing. Practically, these products resisted no longer to handling, transportation, and storage. They lost their shape easily during emptying and shifting them, thus, releasing larger quantities of biomass to the environment. Preliminary evidence of high-viscosity glycerol capable of limiting safe and effective production of high-performance briquettes for heating and power exists.

Starches polymeric films offer several advantages for the replacement of synthetic polymers due to their biodegradability, non-toxicity, availability and low cost. However, the high biodegradation potential can cause fragility, considering some fundamental mechanical properties. Therefore, starch based polymeric films were reinforced incorporating lignocellulosic waste from coffee grounds postconsume. The effect of incorporation of coffee ground in cornstarch matrix and polymer interaction on morphology, thermal and mechanical properties were investigated. The characterization analyzes were based on Dynamic Mechanical Thermal Analysis (DMTA), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA) and Scanning Eletronic Microscopy (SEM). The coffee ground behaved as reinforcement agent according tensile values. Thermochemical conversion showed that polymeric films molding did not change his thermal stability. In temperature range was possible to observe the devolatilization, organic and inorganic compounds decomposition. SEM images showed the coffee ground adhesion in the polymer matrix promoting a better mechanical tensile strength.
