“…Javier Sánchez et al [34] calculated the costs for the whole pellet production chain for vineyard pruning. Only for pelleting, the average cost identified was 56.7€ t −1 , an amount lower than our estimations, but still referring to an industrial plant.…”

The goal of this work was to test a patented pruning harvester and a mobile pelleting system specifically designed for the vineyard agripellet chain. Biomass was characterized before and after storage and after the pelleting stage. The performance, the fuel consumption, and the work quality of the harvester were assessed together with the productivity and the power consumption of the mobile pelleting system. Production costs of pellet were estimated for the whole logistic chain, considering two scenarios: Storage and pelleting directly at the farm site or at a dedicated location at variable distance from the fields. For comparison, the direct production of chips without pelleting was considered. Results indicate that harvester performance was quite good and comparable with commercial solutions; the chips produced exhibited excellent storage performance, allowing direct pelleting without forced drying; the pellet quality was good comparable with that produced from forestry biomass. From an economic point of view, in-field pelleting was the most cost-effective solution, with a good margin of profit up to 57€ t−1; on the other hand, when transport to an intermediate storage center is necessary, profit margin reduces gradually and fades off at an average 50 km distance from the fields.

“…One way to overcome the limitations resulting from the low bulk density and high transport costs is to use densification processes (pelletization and/or briquetting) before using this material for energy purposes, in order to exploit a homogeneous and easy-to-use solid biofuel, which is also characterized by a higher energy density [6,7].…”

“…Pellet production grew from 1.7 million tons in the year 2000 to 28 million tons in 2015 [13], showing an annual increase of 14% compared to 2011 [14]. It is estimated that the demand for pellets from 2020 will be about 50 million tons per year [15] and the consumption of industrial pellets will grow steadily at a rate of 21% year −1 , whereas the increment in the consumption of domestic pellets will reach 8.5% year −1 [7].…”

High-density biomass plantations have played a key role in the national energy landscape in Italy since the 1990s but, to date, an inversion of tendency and a significant reduction of cultivated areas has been noted. Despite this, the existing plantations have seen their coppicing rotation become significantly lengthened, resulting in large quantities of biomass per hectare. This study aimed to identify the best raw material suitable for pellet production using whole trees or stems without branches from poplar plantations at the end of the third, sixth and ninth year of age. All types of pellets made reach the requirements of class A1 for diameter, length, moisture content, ash melting point, lower heating value, as well as nitrogen (N), sulfur (S), and heavy metals. None of the theses satisfied the bulk density parameters while for ashes and mechanical durability, a great variability was observed according to the different raw materials used. An improvement in terms of heating value was observed by transforming the poplar wood chips refined into pellets. The pelletizing process using high density poplar plantation as a raw material highlights the possibility of obtaining a product that meets many of the quality standards required on the market. These aspects are closely related to the innovation carried out in the agro-forestry sector for effective energetic sustainability.

“…The problem‐type used in this paper is the ‘maximize capacitated coverage’ that considers the maximum capacity supply for a provided number of facilities that cover demand within impedance cutoffs (limit of transportation travel time) . The selected locations of biomass depot allow minimizing the overall sum of the weighted impedance with an added constraint of capacity.…”

A decentralized supply chain that integrates biomass depots as an intermediate pre‐processing hub may be an efficient way to obtain stable and dense non‐food carbohydrate commodities that are economically transportable over long distances. This paper presents an integrated geographic information systems (GIS) method based on transport optimization to design and compare the performance of a decentralized versus a centralized biorefinery supply system. The method determines the suitable locations, allocations, sizing, and number of depots according to different demand location scenarios. The method is exemplified by a real case study in southern Quebec. In the design, the biomass depot generates raw sugar, shipped to the biorefinery, and co‐products that are used on site without transportation as animal feed and bioenergy. This diversification strategy provided by a joint production permits savings amounting to two‐thirds of the tonnage on the second transportation arc. The results present the average travel time performance in minutes in different scenarios. In the centralized configuration, the optimized stand‐alone biorefinery location scenario is 45% (59 min) and 58% (100 min) more efficient in terms of transportation than the two biorefineries located in existing industrial parks. However, the latter have a decentralized configuration that is more efficient than their centralized equivalents. In the decentralized configuration, depending on farmer participation, the biorefineries located in the existing industrial park have a transportation performance 16–42% (27–55 min) that is more efficient than their respective centralized configuration. Smaller depots and the use of numerous depots tend to reduce the average impedance as biomass availability increases. This is due to the economies of transportation related to a denser and more meshed network. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
