The need to reduce the environmental impacts of the food industry is increasing together with the dramatic increment of global food demand. Circulation strategies such as the exploitation of self-produced renewable energy sources can improve ecological performances of industrial processes. However, evidence is needed to demonstrate and characterize such environmental benefits. This study assessed the environmental performances of industrial processing of maize edible oil, whose energy provision is guaranteed by residues biomasses. A gate-to-gate Life Cycle Assessment (LCA) approach was applied for a large-size factory of Northern Italy to describe: (i) the environmental impacts related to industrial processing and (ii) the contribution of residue-based bioenergy to their mitigation, through the comparison with a reference system based on conventional energy. The results showed that oil refinement is the most impacting phase for almost all the considered impact categories. The use of residue-based bioenergy was found to drastically reduce the emissions for all the impact categories. Moreover, Cumulative Energy Demand analysis revealed that the use of biomass residues increased energy efficiency through a reduction of the total energy demand of the industrial process. The study demonstrates that the exploitation of residue-based bioenergy can be a sustainable solution to improve environmental performances of the food industry, while supporting circular economy.

“… Glyphosate, alachlor and paraquat are used as herbicides and cypermethrin as insecticide (Patthanaissaranukool & Polprasert, ). The numbers were given in L/ha and are converted to kg/ha by using densities of 1.70, 1.13, 1.25 and 1.25 kg/L for glyphosate, alachlor, paraquat and cypermethrin, respectively. …”

“… The irrigation water is based on the average water productivity in Northeast Thailand stated by Promkhambut, Caldwell, and Polthanee () multiplied with the yield stated in Patthanaissaranukool and Polprasert (). The yields between these different sources are almost similar (1,646–1,971 kg/ha vs. 1,720 kg/ha) indicating that the calculated amount of irrigation water would not be unreasonable.…”

“… For Thailand, two seasons are mentioned, a season from January to April and a second season from June to October (AMIS, ). The inputs for these two seasons are similar, except for a higher water demand and the energy required to pump the water in the dry season (January–April; Patthanaissaranukool & Polprasert, ). In this study, the first (drier) season is used because of water data availability (Promkhambut et al, ). …”

Analysing the water and greenhouse gas effects of soya bean‐based biodiesel in five different regions

Bioenergy may have significant lower greenhouse gas (GHG) emission intensities compared to fossil alternatives, but concerns are raised that bioenergy would contribute to additional water scarcity. Therefore, the GHG intensity, water intensity and water‐related risks are analysed simultaneously for conventional diesel and soya bean‐based biodiesel from Argentina, Brazil, Unites States (U.S.), Thailand and Iran on a life cycle basis. The water‐related risks are estimated with a water scarcity—consumption matrix, which was recently developed. Results show that a significant share (9%‐38%) of the GHG emissions in all biodiesel cases is caused by soil N2O emissions. In addition, the ranges in water consumption intensity for soya bean‐based biodiesel are considerably larger than for fossil fuels. However, whether this leads to high water‐related risks depends on the local water scarcity. Soya bean‐based biodiesel from Argentina has low water‐related risks to all nodes of the supply chain due to low local water stress combined with a low direct water consumption intensity (20 L/GJfuel). In addition, high GHG emission reduction (71%) and a low‐specific eutrophication potential (0.04 kg PO43−/GJfuel) are achieved. The indirect water consumption intensity is estimated at 120–420 L/GJ for soya bean‐based biodiesel, which is significant if the soya beans are rainfed, like in Argentina and Brazil. If irrigation is required, indirect water consumption is dwarfed by irrigation water. Overall, it is concluded that soya bean‐based biodiesel can have significant lower GHG emission intensity than fossil diesel, without causing additional water stress in the supply chain if they are produced in water abundant areas and good agricultural practices are used. The used method shows disaggregated water‐related risks for the different nodes of the supply chain to acknowledge the regional nature of water scarcity and enables decision makers to identify “hot spots” and take targeted actions.
