Life cycle greenhouse gas (GHG) impacts of a novel process for converting food waste to ethanol and co-products

Environmental trade-offs in fresh-fruit cold chains by combining virtual cold chains with life cycle assessment

“…The methods provided in this paper can also be applied for related application areas, optimizing the logistics of agricultural products and lowering food waste and environmental impacts. A typical example is the use of LCA for evaluating conversion of food waste into biogas by recycling [28,29]. Here, mechanistic modeling could help optimizing different unit operations, such as the dehydration process for example, and thereby enrich LCA input data.…”

“…The recent development of LCA methodologies and dissemination programs by international and local bodies is the basis for LCA's increased use on agricultural and industrial food products [27]. In a related context, LCA is also used to evaluate the conversion of food waste into biogas by recycling [28,29] or the use of renewable energy in distribution networks of perishables [30].…”

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

“…Thus, the pretreatment stage is not very demanding in terms of energy (heat) or additional materials (acid, alkali, organic solvents etc.). The same is true for some industrial food wastes with high sugar content, for example, palm oil frond [13], banana waste [18], brewery waste [19] and fruit syrups [21], which can be utilized for the production of ethanol without energy-intensive pretreatment processes. Once the pretreatment step has been concluded, the hydrolysis step follows.…”

Material flow analysis of alternative biorefinery systems for managing Chinese food waste

“…Data on distillation was adopted from (Balat, 2011). Bioethanol is distilled off as a product; in our work, we used a distillation efficiency of 96.5% (of bioethanol) (Ebner et al, 2014).…”
