Integration of logistics network in local food supply chains
Get PDFThe demand for locally produced food is increasing as global food supply system has considerably affected the confidence of consumers by increasing tonne-kilometres, food safety risk, environmental impact, and disconnecting local food producers and consumers. However, local food suppliers are not in the position to compete with large scale food supply systems due to high logistics costs. The overall objective of this study was to improve the logistics management of local food supply chains. In this thesis, food traceability issues and the local food supply chains were studied based on literature reviews and five case studies in Sweden.
The thesis comprises of six papers. Paper I considers food traceability issues. Paper II deals with comparison analysis of small scale abattoir and large scale abattoir in terms of animal supply and meat distribution. Paper III focuses on box-scheme based organic food delivery system, while Paper IV deals with coordination and regional integration in local food delivery system. Papers V and VI consider the case of clustering producers, determining collection centres, and forming coordination and integration within the network and further integration into large scale food delivery systems. The best locations of collection and distribution centres were determined using Centre-of-Gravity and Load-Distance techniques and Geographic Information Systems tools. Optimising food transport routes were done with Route LogiX and ArcGIS network analyst tools.
Effective food traceability system is an important tool to be considered as integral part of food logistics system as it facilitates the integrated management of food supply chain as a whole. Compared with large scale abattoirs, the local small scale abattoir could reduce travel distance, time, and emission and could improve animal welfare, meat quality and safety, and customer satisfaction. The integration of logistics managements along with clustering, coordination, and optimisation techniques, could reduce the transport distance, time, trips, and emission, and improve the vehicle capacity utilisation in the local food supply chains. As a consequence of reduced transport distance, number of vehicles and improved vehicle capacity utilisation, negative environmental impacts of local food supply systems could be reduced. The study revealed that the integrated logistics network has implications for improving food traceability, logistics efficiency, food quality and safety, the potential marketing channels, economic benefits, and competitiveness of suppliers; and for attenuating negative environmental impact and promoting sustainable local food systems
Life Cycle Assessment of Dried Organic Apple Value Chains Considering Conventional and Heat-Pump-Assisted Drying Processes: The Case of Sweden
Get PDFThe increasing population pressure and demand for quality food, and the significant burden of agriculture on the environment, impede the sustainable development of the food sector. Understanding the environmental performance of different agricultural technologies and food value chains and identifying improvement opportunities play important roles in the sustainable development of this sector. This article presents the results of an environmental impact assessment of organic dried apples produced and supplied in Sweden, which was conducted using primary and literature-based data. A "cradle-to-consumer gate" life cycle analysis (LCA) method with a functional unit (FU) of 1 ton of fresh organic apples at the farm stage was used while considering conventional drying and heat-pump (HP)-assisted apple-drying techniques. The main environmental impact categories investigated were cumulative energy demand (CED), climate change impact (GWP), acidification potential (AP), and eutrophication potential (EP). The results indicate that the total CED values were 7.29 GJ and 5.12 GJ per FU for the conventional drying and HP-assisted drying methods, respectively, i.e., a reduction of about 30%. Similarly, the GWP values were 130 kg CO2 eq and 120 kg CO2 eq per FU, respectively. These findings highlight the importance of improving energy use and process efficiency to increase the sustainability of dried organic apple value chains
Environmental impact of organic and conventional carrots
Get PDFThe total cumulative energy demand was about 2.64 GJ in
the case of fresh carrot and 6.67 GJ in the case of dried carrot value chain. Climate change impact was about 121 kg CO2 eq for fresh carrot and 111 kg CO2 eq for dried carrot
Environmental Impact Assessment of Organic Wheat Cracker Value Chains with and without Nettle Powder as a Natural Additive: A Case of Sweden
Get PDFDue to the growing global population and consequent increased demand for food, the global production of cereal crops has increased. Wheat is one of the most important food crops in the world, as its products, e.g., bread and crackers, have served as important sources of nutrition for many years. However, the environmental impacts of wheat-derived food products are not frequently explored. This study presents an environmental impact assessment of organic wheat crackers within the context of Swedish winter wheat production using both primary and literature-based data. A cradle-to-consumer gate life cycle analysis (LCA) approach using the functional unit (FU) of 1 kg of crackers was applied while considering two cracker value chains: (i) without additives and (ii) using nettle powder as a natural additive. Four environmental impact categories-cumulative energy demand (CED), climate change impact (GWP), acidification, and eutrophication-were explored, with a particular focus on CED and GWP. The analysis results indicated that the total CED values were about 13 MJ/FU and 14 MJ/FU for crackers without and with the additive, respectively. Similarly, the total GWP values were 379 g CO2 eq/FU and 464 g CO2 eq/FU, respectively. The post-harvest processing and handling stage was an environmental hot spot in both cases. The introduction of the nettle additive has increased the quantified values of all four of the investigated impact categories. These insights will enable food processors and policy makers to communicate the environmental impacts and make informed decisions to improve the sustainability of wheat crackers. This paper contributes to a database of the environmental impacts of wheat products, specifically LCA data of organic wheat crackers and the LCA method for further LCA studies of snacks and other wheat products with plant-based functional additives
Urban Freight Last Mile Logistics-Challenges and Opportunities to Improve Sustainability: A Literature Review
Get PDFLast mile logistics (LML) is the least efficient and complex part of supply chain. The main objective of this study was to identify major challenges of urban freight LML and opportunities for intervention. For this, 42 peer-reviewed full papers published after 2010 and three additional references were used. The findings indicated that urban freight flow has a trend of steady growth. The main driving forces behind this steady growth are population growth, urbanization, densification, globalization, online and omni-channel (OC) retailing, and urban economic development. Using typology analysis, three main potential freight LML configurations were mapped and discussed. Freight LML configurations that involve light cargo vehicles and cargo bike-based delivery schemes could be more attractive freight LML models if the delivery failure is minimized. The LML challenges were categorized as technological, infrastructural, LML system and management, and logistic cost related challenges, and discussed broadly. Similarly, the potential opportunities were discussed from environmental, economic, and social sustainability aspects. Finally, this report has pinpointed future potential research agendas related to LML. The study could be a knowledge base useful for academicians and practitioners, logistics and technical service providers, policy makers, and customers

Multipurpose simulation model for pasture-based mobile Automated Milking and Marketing System, Part-I: Pasture, milk yield, and milk marketing characteristics
Get PDFIt is essential to promote sustainable dairy farming which could lead to improved animal welfare, economic benefits, biodiversity and environmental benefits, milk quality, and customer satisfaction. In this regard, a mobile automated milking system (AMS) could contribute a lot. However, mobile AMS is a new innovative system which is not investigated well. Therefore, a simplified and integrated management approach should be introduced. The main objective of this study was to develop a multipurpose simulation model (DigiMilk model) specific to pasture-based mobile AMS. The model comprises five major subsystems: Pasture yield as dry matter (DM) and grazing characteristics; AMS Milking and milk yield characteristics; Milk handling and marketing; Resource consumption; and Economic assessment. This paper (Part-I) focuses on the first three components while the remaining two subsystems would be addressed in Part-II of this paper. DigiMilk model was built in MATLAB-Simulink environment. It was tested and evaluated using mainly secondary data and limited primary information acquired from a dairy farm in central Sweden. In this initial analysis, a continuous stocking system on pasture was assumed to be implemented from May 15 till September 15. Multiple sensitivity analyses were successfully conducted to get more insights. The results indicated that, considering maximum pasture growth rate of 77 kgDM day−1ha−1, the accumulated average pasture yield, over the grazing season, was estimated to be 6928 kgDM ha−1. For cows with average grazing rate of 16–18 kgDM day−1cow−1, the stocking rate of 3 cow ha−1 could lead to good performance of grazing management. When stocking rate and grazing rate of 3 cow ha−1 and 16 kgDM day−1cow−1 were considered respectively, the cumulative milk yield values (excluding amount consumed by calves) over the grazing season were estimated to be 2101 L cow−1 and 6303 L ha−1. Out of this 6303 L ha−1, 2952 L ha−1was estimated to be sold on-site, using milk vending machine (MVM), while 3351 L ha−1 was to be delivered to super market. The accuracy of results from the the simulation model could be improved with future work with more real data from actual demonstration of mobile AMS over the entire grazing season. In addition to its capacity to serve as an integrated decision making tool, DigiMilk model enables to have organized digital data that could be useful for future researches to evaluate the environmental and/or economic performances of pasture-based dairy systems with mobile AMS
