“…Sawdust Currently, sawdust is commonly used for energy generation by the pulp and paper industry [50]. Other applications include manufacturing fiberboards and particle boards [15,51,52] and the production of pellets, a significant renewable solid fuel [51][52][53]. The small size of sawdust does not allow its use for pulping due to overprocessing [48].…”

“…From the point of view of residues valorization, as abovementioned, the presence of monomeric sugars represents a high competitive advantage of SSL [69]. The main challenge associated with SSL bioprocessing is the presence of some degradation products, such as acetic acid, furfural and low molecular weight lignosulfonates, that inhibit microbial metabolic activities [53,77,146,147]. The detoxification of SSL is a way to reduce these inhibitory effects focused on improving its bioprocessability through the neutralization and/or removal of the inhibitors [116,119].…”

The pulp and paper industry is recognized as a well-established sector, which throughout its process, generates a vast amount of waste streams with the capacity to be valorized. Typically, these residues are burned for energy purposes, but their use as substrates for biological processes could be a more efficient and sustainable alternative. With this aim, it is essential to identify and characterize each type of waste to determine its biotechnological potential. In this context, this research highlights possible alternatives with lower environmental impact and higher revenues. The bio-based pathway should be a promising alternative for the valorization of pulp and paper industry wastes, in particular for bioproduct production such as bioethanol, polyhydroxyalkanoates (PHA), and biogas. This article focuses on state of the art regarding the identification and characterization of these wastes, their main applied deconstruction technologies and the valorization pathways reported for the production of the abovementioned bioproducts.

“…Blending can also reduce compaction energy and thus consumes less energy in the pressing process [13,14]. In addition to wood/agricultural residues blending, the mixing of various agricultural wastes [15,16], co-pelleting of agro-wastes with other residues, such as sewage sludge, pyrolysis oil and hydrolysis lignin, has also been reported [17][18][19][20]. Table 1 lists a short summary of biomass blending reported in the literature.…”

“…The main advantages linked to them include avoidance of significant levels of emissions compared to fossil fuels [13], a potential reduction in heating costs, an increased comfort [14], and an improvement in calorific value in relation to biomass without densification [15,16]. Besides, pellet quality can be improved using co-pelletization [17][18][19]. This blending process helps with many of the problems present in different raw materials [20] at the same time that energy use is granted to materials that could be considered wastes.…”

Influence of Varieties and Organic Fertilizer in the Elaboration of a New Poplar-Straw Pellet and Its Emissions in a Domestic Boiler

et al. 2020

Pollutants resulting from domestic combustion would have harmful effects on public health, causing disturbances in the atmosphere chemistry and the climate. In this work, the emissions from the combustion of pellets made of 80% poplar (organically fertilized) and 20% cereal straw (Triticum aestivum) have been analysed. Poplar wood from I-214 and AF-8 clones was obtained from fertilized and non-fertilized plots (CONTROL). Dairy wastewater treatment (MUD) and dehydrated sewage sludge (BIOSOLIDS) were the fertilizers employed. BIOSOLIDS-I214 pellets had lower quality standards, so its combustion was omitted. A flue gas sample was sampled together with the particles emitted. The I-214 MUD sample had the highest emitted CO value (1505 mg/MJ). Regarding HCl emission factors, there was a homogeneity in the results linked with the Cl content present in the raw material. A higher particle emission was associated with pellets with higher ash content. Particles were composed mainly for elemental carbon (26–80 mg/MJ), except I-214 MUD. I-214 pellets had the indicators of incomplete combustion and, therefore, major contaminants emission and major environmental impact. Thus, both the poplar clone and the organic fertilizer influenced the parameters and emissions analysed. Therefore, special attention must be paid to both characteristics.
