“…In literature, also reuse of residues in many other productive contexts are taken into consideration. In energy sector the residual biomass deriving from cultivation is used for combustion (Fernández et al, 2006;Alaru et al, 2011), for biogas production (Garcia-Peña et al, 2011;Oliveira et al, 2012;Bacenetti et al, 2013;Mönch-Tegeder et al, 2014;Pagés-Díaz et al, 2014) and in more complex processes such as pyrolysis, gasification (Encinar et al, 2000(Encinar et al, , 2002 and hydrolysis (Luo et al, 2011) with the consequent production of new biofuels. Moreover, following different process techniques the crop residues can be used for the production of bio-based (Cherubini and Ulgiati, 2010;Pronyk and Mazza, 2012).…”

“…Lignin in biomass can enhance the binding characteristics of densified banquette during the preheating of the material [6]. A higher lignin with a small particle size and low moisture glues the briquette more strongly together [7]. In this study, the fractures on the surface probably were effected by irregular size of particles.…”

Abstract-This research aimed to study the quality of the fuel briquettes made from sewage sludge mixed with water hyacinth and sewage sludge mixed with sedge. Sewage sludge were mixed with water hyacinth and sedge at the ratios of 1:1, 1:2, 1:3, 2:1 and 3:1 then compressed these mixtures with hydraulic pressure to obtain fuel briquettes and finalized them by analyzing fuel briquettes properties including moisture content, calorific value and compressive strength, then comparing them to the properties of the wood charcoal standard. The result showed that the ratio of wastewater sludge and sedge at 1:3 provided the highest calorific value (3,362.9 cal/g) but still lower than the standard (5,000 cal/g) and the ratio of wastewater sludge and water hyacinth at 1:3 gave the highest compressive strength value (4,545 N). And the moisture content of them was between 4.78% and 7.86%.

“…Densification (briquetting or pelleting) of biomass aims to increase the bulk density of agricultural residues far beyond what is achievable by baling, and it is an essential step for providing biomass with sufficient caloric density for efficient transportation [138]. The production of biomass pellets provides a substrate that is suitable for conversion into biofuels through microbial processes or gasification [139,140], or can be combusted directly to produce energy [141]. A wide variety of agricultural feedstocks is suitable for pelleting [142]; however, untreated biomass is very difficult to densify and, without pretreatment, produces weak, powdery pellets that are expensive to produce and cannot withstand the physical rigors of transportation.…”

Additional information is available at the end of the chapter http://dx.doi.org/10.5772/55088 . IntroductionMuch of Earth s recent geologic history is dominated by periods of extensive glaciation, with relatively low global mean temperatures and correspondingly low atmospheric CO concentrations [ ]. The current interglacial period stands out as an anomaly because the atmospheric CO concentration has risen sharply above the range of approximately -parts per million by volume that has defined the past , years to reach levels that are nearly % higher than the biosphere has experienced over this time frame [ ]. This rapid increase in CO concentration is primarily due to the release of ancient fixed atmospheric CO into the modern atmosphere through the combustion of fossil fuel resources over the past years. Since it is clear from ice core records that atmospheric CO concentration has a strong positive correlation to global temperature, it is expected that changes to global climate are forthcoming [ ]. There are substantial uncertainties regarding the ability of terrestrial and oceanic carbon sinks to absorb this anthropogenic CO on time scales that are relevant to human society [ ], so the continued release of ancient CO into the modern atmosphere at current rates carries with it an important risk of inducing climate changes of unknown amplitude along with a host of ancillary changes that are difficult to predict with certainty. This has led to the search for alternatives to fossil fuels to meet a rising global energy demand, and one such option is the use of extant organic matter to produce energy. This resource contains carbon that was fixed from the modern atmosphere, which means it does not result in a net increase in atmospheric CO upon combustion.
