“…yield (mol%) = (m glucose × 0.90)/(m substrate × G f ) × 100 (5) Xyl. yield (mol%) = (m xylose × 0.88)/(m substrate × X f ) × 100 (6) where the numbers 0.90 and 0.88 take into account the stoichiometry and the molecular weights in the hydrolysis of cellulose and hemicellulose, respectively to glucose and xylose; whereas G f and X f represent the percentage (wt%) of glucan and xylan in the composition of the starting substrate, respectively.…”

“…The anticipated depletion of fossil resources in the nearest future together with their associated unfavorable environmental outcomes are driving research towards the exploration of promising alternative renewable resources. These alternative renewable resources include lignocellulosic biomass [1,2], animal manure and human sewage [3,4], meat processing waste [5,6] and aquatic biomass [7,8], which can be employed as biorefinery feedstocks. Among them, the lignocellulosic biomass represents a key feedstock, being abundant, safe, and cheap and it is mainly composed of three biopolymers (cellulose, hemicellulose and lignin), which are precursors of very valuable bio-products and biofuels [9,10].…”

Lignocellulosic biomass represents one of the most important feedstocks for future biorefineries, being a precursor of valuable bio-products, obtainable through both chemical and biological conversion routes. Lignocellulosic biomass has a complex matrix, which requires the careful development of multi-step approaches for its complete exploitation to value-added compounds. Based on this perspective, the present work focuses on the valorization of hemicellulose and cellulose fractionsof giant reed (Arundo donax L.) to give second-generation sugars, minimizing the formation of reaction by-products. The conversion of hemicellulose to xylose was undertaken in the presence of the heterogeneous acid catalyst Amberlyst-70 under microwave irradiation. The effect of the main reaction parameters, such as temperature, reaction time, catalyst, and biomass loadings on sugars yield was studied, developing a high gravity approach. Under the optimised reaction conditions (17 wt% Arundo donax L. loading, 160 °C, Amberlyst-70/Arundo donax L. weight ratio 0.2 wt/wt), the xylose yield was 96.3 mol%. In the second step, the cellulose-rich solid residue was exploited through the chemical or enzymatic route, obtaining glucose yields of 32.5 and 56.2 mol%, respectively. This work proves the efficiency of this innovative combination of chemical and biological catalytic approaches, for the selective conversion of hemicellulose and cellulose fractions of Arundo donax L. to versatile platform products.

“…The methyl esters remained in the oily phase and could be used for transesterification directly with alkaline catalysts. On the other hand, a biorefining strategy for animal fat waste was proposed for the conversion of free fatty acids into triglycerides that could be blended with fossil diesel and be used in engine combustion systems [129]. Recently, adsorbents like magnesium aluminum hydroxycarbonate and 1,3,5-trimethyl-2,4,6-tris(3,5-ditert-butyl-4-hydroxybenzyl) benzene were proposed to enhance the oxidative stability of biodiesel and its blends and therefore retard their degradation.…”

The agro-food industry generates large amounts of waste that contribute to environmental contamination. Animal fat waste constitutes some of the most relevant waste and the treatment of such waste is quite costly because environmental regulations are quite strict. Part of such costs might be reduced through the generation of bioenergy. Biodiesel constitutes a valid renewable source of energy because it is biodegradable, non-toxic and has a good combustion emission profile and can be blended up to 20% with fossil diesel for its use in many countries. Furthermore, up to 70% of the total cost of biodiesel majorly depends on the cost of the raw materials used, which can be reduced using animal fat waste because they are cheaper than vegetable oil waste. In fact, 6% of total feedstock corresponded to animal fat in 2019. Transesterification with alkaline catalysis is still preferred at industrial plants producing biodiesel. Recent developments in heterogeneous catalysts that can be easily recovered, regenerated and reused, as well as immobilized lipases with increased stability and resistance to alcohol denaturation, are promising for future industrial use. This manuscript reviews the available processes and recent advances for biodiesel generation from animal fat waste.

“…Yellow grease is a common raw material for biodiesel production and it can be used after filtration and cleaning (33,34). Animal fats are generally formed of a mixture of TGs, proteins, water, and diverse minerals (35). WAFs often collected from animal slaughterhouses or fish factories (36).…”

“…Biodiesel derived from WAFs has a high cetane number but low pour point due to the presence of FFAs and low oxidative stability due to the lack of natural antioxidants (37). There are many published studies (35,38,39) that describe feasibility and features of biodiesel production from such sources as tallow (cattle, ship, and goat), lard (pig), poultry fat (birds and fish). According to the U.S. Energy Information Administration (EIA) Monthly Biodiesel Production Report, EU countries, USA, China, Brazil, and Canada are rhe main produsers of biofuel from UCOs and WAFs.…”

Although fossil fuels remain the main source of energy, the volume of renewable sources of energy is constantly increasing. Biodiesel is a promising alternative fuel due to the number of advantages compared to fossil fuel and other types of biofuel. The specific objective of this study was to identify the difference between conventional and novel technologies applied during the whole life cycle of biodiesel production and consumption. The study offers some important insights into the recent advances in the biodiesel industry including biodiesel production from microalgal lipids, advanced homogenous and enzymatic transesterification, non-catalytic supercritical transesterification, application of microwave and ultrasound assisting technologies. Considering all the factors affecting the efficiency and safety of the biodiesel production process, here we reviewed the main principals and recent achievements in the environmental life cycle assessment of biodiesel production and consumption.
