“…Biomass has a high demand, especially for heating. In [62] was estimated that in British Columbia in Canada, biomass potential coming from residue crops could reduce up to 2% of GHG. Technical and economic evaluations of waste management have been previously performed.…”

The industry sector has a significant responsibility for the depletion of fossil fuels and emission of carbon dioxide. Thus, several initiatives have been implemented by the industry sector to mitigate those issues. One initiative corresponds to the implementation of energy efficiency strategies. In particular, the food industry is heavily dependent on fossil fuels, and the food demand is expected to grow significantly in the coming years. Therefore, developing energy efficiency strategies for this particular industrial sector is crucial. This paper investigates the different opportunities for energy efficiency in the food industry. It first provides a brief overview of the various food industries and related energy consumption. Then, the different options for energy efficiency in the thermal and electric sector are discussed. New trends and opportunities, arising from industry 4.0 and demand response, are also presented.INDEX TERMS Energy efficiency, food industry, industry 4.0, renewable energy, waste-to-energy.

“…For example, Becerra-Ruiz et al (2019) reported a decrease of 99, 93, and 67% in CO, HC, and NOx, respectively, when a 5500 W portable engine generator of alternating current burned bioethanol instead of gasoline. Compared to first-generation bioethanol such as corn and sugarcane-based bioethanol, second-generation bioethanol (i.e., bioethanol produced from lignocellulosic feedstocks) has significantly lower life cycle GHG emissions (Wang et al, 2020). Moreover, bioethanol yields of forest biomass are relatively higher than those of other types of biomass.…”

“…Compared to the biochemical conversion, thermochemical conversion, particularly gasification, can be applied to a broader range of forest biomass (Wang et al, 2020). During gasification of the lignocellulosic biomass at high pressure and in the absence of inert gases, lignocellulosic biomass is converted into syngas, which will then be converted into bioethanol through the Fischer-Tropsch process (Laesecke et al, 2017).…”

Biomass plays a crucial role in mitigating the concerns associated with increasing fossil fuel combustion. Among various types of biomass, forest biomass has attracted considerable attention given its abundance and variations. In this work, an overview is presented on different pathways available to convert forest biomass into bioenergy. Direct use of forest biomass could reduce carbon dioxide emissions associated with conventional energy production systems. However, there are certain drawbacks to the direct use of forest biomass, such as low energy conversion rate and soot emissions and residues. Also, lack of continuous access to biomass is a severe concern in the long-term sustainability of direct electricity generation by forest biomass. To solve this problem, co-combustion with coal, as well as pelletizing of biomass, are recommended. The co-combustion of forest biomass and coal could reduce carbon monoxide, nitrogen oxides, and sulfide emissions of the process. Forest biomass can also be converted into various liquid and gaseous biofuels through biochemical and thermochemical processes, which are reviewed and discussed herein. Despite the favorable features of forest biomass conversion processes to bioenergy, their long-term sustainability should be more extensively scrutinized by future studies using advanced sustainability assessment tools such as life cycle assessment, exergy, etc.

“…But even in this case, there is no single functional unit which could allow a comparison. Other studies use as functional unit 1 TJ bioenergy [8], others 1MJ ethanol [9,10] or 1kg ethanol [11]. When the focus of the study is on the ethanol production technologies then a volumetric unit of ethanol (i.e., 1L or 1 ton) is prefered as the functional unit [12][13][14].…”

Life Cycle Analysis of the Bioethanol Production from Food Waste—A Review

2020

View full text Add to dashboard Cite

Food Waste (FW) because of its composition is considered as an ideal feedstock for the production of biofuels and in particular bioethanol. The production of bioethanol from lignocellulosic materials has been studied over a long time. The process consists of the stages of pretreatment, enzymatic hydrolysis, fermentation and product recovery. However, the legal framework regarding biofuels has established specific environmental criteria for their production which are regularly updated. The most common tool for the assessment of the environmental performance of a process or product is the Life Cycle Analysis (LCA). In the present review, the results of LCA studies on the production of bioethanol from food waste are presented. Significant differences are observed among the studies in terms of the methodological choices made. Despite the high heterogeneity observed which does not allow a direct comparison among them, there is strong evidence that the production of bioethanol from food waste is an eco-friendly process which can substantially contribute to Green House Gas (GHG) emissions savings.
