Optimizing transport to maximize nutrient recycling and green energy recovery

Key Factors for Site-Selection of Biogas Plants in Sweden

“…Coordinated action among stakeholders (from multiple biogas companies, to municipal governments and farmers) can benefit from geo-spatially explicit systems analysis of site-locations to screen for strategic locations for biogas production given stated priorities (e.g. Metson et al (2021aMetson et al ( , 2021b) which looked at maximizing nutrient recycling and minimizing transport costs). Considering the influential role of land-use planning documents on biogas plants, and the (often) slow update process of such documents, explicitly integrating biogas solutions would facilitate win-win expansion across these functions.…”

“…manure from livestock production) to areas where they are highly demanded (e.g. crop production regions) (Metson et al, 2021a(Metson et al, , 2021b. If plant locations are not coordinated, then there is a chance that plants that are built at a later date cannot effectively contribute to nutrient recycling because transport distances are economically unviable.…”

“…When parameters (factors) for site-selection of a single (or group of) biogas plant(s) are known, and geo-spatial information about the region is available, site-selection analysis can be assisted by mathematical approaches such as optimization (e.g. Metson et al, 2021aMetson et al, , 2021b or quantitative multi-criteria analysis (e.g. Akther et al, 2019).…”

The Potential of Digestate and the Liquid Fraction of Digestate as Chemical Fertiliser Substitutes under the RENURE Criteria

“…With an estimated 180 Mt of digestate produced in the EU-28 each year [67], it is believed that less than 8% of the livestock manure in the EU finds its way to processing facilities [64]. This indicates that, on one hand, there is still significant leeway to increase GHG emission abatement from manure by way of biogas production [11,68] and, on the other hand, that there is still room for growth for nutrient recovery and recycling.…”

Swedish food system transformations: Rethinking biogas transport logistics to adapt to localized agriculture

“…Actors (e.g., biogas plant operators) that currently use organic waste as feedstock go to considerable lengths to minimize costs associated with acquiring this feedstock and reaching markets with products or residues ( Ammenberg and Feiz, 2017;Long et al, 2018 ). Previous work also shows that coordination among multiple actors, at multiple spatial and organizational scales, is required to minimize these transport costs and maximize benefits ( Koppelmåki et al, 2021;Metson et al, 2020 ). Costs are a function of distance, weight, handling, and actual purchasing cost versus market value of the final product; finding ways to minimize these parameters requires spatially explicit information ( Akram et al, 2019b;Hamelin et al, 2019 ).…”
