Food Loss

PurposeThe purpose of this paper is to measure food loss and waste by material flow analysis (MFA) tool. Applying this methodology, the authors estimate wastage-related losses and discuss opportunities for more circular and sustainable practices in the Italian potato industry.Design/methodology/approachMFA is applied to two specific typologies as follows: ready-to-eat (chips) and dried potato products produced in Italy. The analysis refers to the year 2017 as the complete dataset useful for this study includes measurements until this year. A bottom-up and top-down mixed approach is applied, and functional unit refers to 1 t of potatoes consumed as final product.FindingsMFA is applied to quantify and qualify material balance associated with 1 t of potatoes consumed as final product. In Italy, in 2017, more than 22,000 t of fresh tubers were lost, including 3,500–4,800 t of starch, equivalent to 52,800–72,600 GJs. Moreover, fewer than 23,000 t of skins and scraps were produced within industrial plants, not available for food but suitable for animal feed (dry skins are an excellent carbohydrates source in cattle and poultry feed), starch industry and bioenergy production (biogas and/or bioethanol).Originality/valueThis research is one of the few studies proposing MFA methodology as a tool to measure food waste. This analysis shows its utility in terms of food waste quality/quantity evaluation, supporting both company management and policymakers.

PURPOSE To determine the cost of transfusing 2 units (U) of packed RBCs at a comprehensive cancer center. METHODS We performed a process-flow analysis to identify all costs of transfusing 2 U of allogeneic packed RBCs on an outpatient basis to patients with either (1) solid tumor who did not undergo bone marrow transplantation (BMT), (2) solid tumor who underwent BMT, (3) hematologic malignancy who did not undergo BMT, (4) hematologic malignancy who underwent allogeneic BMT, or (5) hematologic malignancy who underwent autologous BMT. We conducted structured interviews to determine the personnel time used and physical resources necessary at all steps of the transfusion process. RESULTS The mean cost of a 2-U transfusion of allogeneic packed RBCs was $548, $565, $569, $569, and $566 for patients with non-BMT solid tumor, BMT solid tumor, non-BMT hematologic malignancy, allogeneic BMT hematologic malignancy, and autologous BMT hematologic malignancy, respectively. Sensitivity analysis showed that total transfusion costs were sensitive to variations in the amount of clinician compensation and overhead costs, but were relatively insensitive to reasonable variations in the direct costs of blood tests and the blood itself, or the probability or extent of transfusion reaction. CONCLUSION The costs of the transfusion of packed RBCs are greater than previously analyzed, particularly in the cancer care setting.

A Multi-sectoral Systems Analysis (MSA) model has been constructed for exploring and managing cross-sectoral impacts (both synergies and antagonisms) resulting from technology and policy interventions in the design and stewardship of city infrastructures. This MSA is based on Substance Flow Analysis. It accounts for the flows of water, nitrogen, phosphorus, carbon, and energy into, around, and out of the water, energy, food, waste-handling, and forestry sectors of city-watershed systems. Applications of the MSA to two case studies of the Metropolitan Atlanta Area in Georgia, USA, and the Greater London Area, UK, are compared. The impacts and financial benefits are assessed for four candidate technological innovations in the water sector: urine-separating toilets; pyrolysis of sewage sludge; combined food-waste and wastewater conveyance/treatment; and production of algae-based biofuels from sewage. System-wide environmental sustainability is gauged on four accounts, of attaining progressively more ambitious targets of resource savings/recovery in respect of water, energy, and nutrients (both nitrogen- and phosphorus-based). The paper closes by demonstrating how the MSA can provide assistance in framing questions of a more financial and social nature, i.e., those of ‘Who reaps the rewards?’ and ‘Who bears the costs?’ of the various prospective technological changes and (possibly) breakthroughs.

Mixed Approach

PurposeThe study proposes Material Flow Analysis (MFA) methodology as a tool to measure and qualify food waste in the Italian beef supply chain in each stage of the food supply chain, from farm to fork. In particular, the authors attempt to: (1) measure resources consumption and waste generation toward companies' and policymakers' sustainable evaluations; (2) enhance consumers' education in the field of agri-food resilience and sustainability.Design/methodology/approachMFA is applied to the entire Italian sector of beef consumed as packaged fresh product in 2020, during the Covid-19 pandemic. The analysis regards bovine, which represent roughly one-third of the national meat flow. To collect data, bottom-up and top-down mixed approach is applied. Subsequently, MFA results are used to calculate the wastage-related losses in terms of embedded natural resources (e.g. water, energy).FindingsIn 2020, it results that the Italian meat industry slaughtered more than 1.15 Mt of bovine to produce approximately 0.29 Mt of fresh meat, 0.69 Mt of by-products and over 0.015 Mt of food waste at households, while 0.15 Mt of beef meat is destined to catering services and food industry (out-of-boundaries). In terms of hidden natural resources, it emerged that, on average, more than 94bn m3 of water, approximately 101,000 TJ of energy and over 11,500 t of PET and PE trays are required to sustain the entire beef system.Originality/valueThis research is one of the few studies proposing MFA methodology as a tool to measure food waste and hidden associated flows in the agri-food sector. This analysis shows its utility in terms of natural resources (water, energy, materials) and waste quality/quantity evaluation, hidden flows accounting and development of new educational strategies toward food waste minimization and sustainability at household consumption.
