“…Stabilized residue (digestate) can be used as fertilizer after the fermentation process (Marada et al [30]). Since agricultural AD plants process specific agricultural products, be they of plant or animal origin, whose production is spatially rooted in different natural conditions, it can be stressed that the location of agricultural AD plants is highly dependent on this production, especially since these products have a low value/weight ratio, making them rather expensive to transport (mathematical models of this dependence were recently reviewed in Balaman and Selim [31]; Kythreotou et al [32]; Neiva de Figueiredo and Mayerle [33]). …”

There is fundamental agreement about the environmental benefits of renewable energy technologies, but unintended consequences arising from their deployment are frequent sources of conflicts. The Czech Republic has committed itself to supply 13.5% of its electricity consumption from renewable sources by 2020. High state incentives for renewable energies have been provided to achieve this target, however critical questions can be asked about the appropriateness of the design of the supporting frameworks which caused a boom in photo-voltaic (PV) installations on agricultural land, as well as a boom in the installation of agricultural anaerobic digestion (AD) plants fueled by dedicated energy crops. This paper analyses the diffusion of agricultural AD plants in the Czech Republic, focusing especially on locational characteristics in relation to the quality of agricultural land, agricultural and population census data. Statistical analysis of those spatial datasets show that agricultural AD plants are mostly located in less favourable agricultural areas, in regions having recently experienced a reduction in cattle breeding, and in regions with significant increases of sowing areas of green maize. These findings suggests shortcomings in the supporting policy for AD plants in the Czech Republic, resulting in unintended environmental consequences, and missed opportunities to enhance energy self-sufficiency and resilience in the countryside.

“…While the AES model allows for agriculture to become a net producer of energy, the spatial scale of this energy production is restricted. This is because the long-distance transport of these biomasses or of produce energy is not economically feasible [17][18][19], and local energy demand does not match energy production. This is a challenge, especially in rural areas where biomasses are readily available, but the demand for energy, apart from electricity, is often limited to a farm's own electricity and heat consumption.…”

Food-Energy Integration in Primary Production and Food Processing Results in a More Equal Distribution of Economic Value Across Regional Food Systems: Nordic Case Study from Circular Perspective

Circular food systems have been proposed as an alternative to the current dominant linear food chain structures. Biomass production for food and energy and nutrient recycling have been defined as the most important elements of circular food systems. Thus far, the potential role of food processing as a large biomass and energy user has gained little attention in studies of the circular bioeconomy. In this study, we explore how compatible bioenergy production is with the energy consumption of regional food processing and how such integrated systems may impact on the economic value created in regional food systems. We applied the nested circularity framework to three contrasting regions to study from an economic perspective the economic value created in primary production, food processing, and bioenergy production. In addition to this, we also calculated the value of external nutrient and energy inputs used in food production. Our results showed how energy production from agricultural biomasses can provide enough energy for food processing on a regional scale, but that this would require integrating food processing with primary production. As a result of this integration, the economic value created in food processing decreased substantially in two of the case study regions, but in contrast, the value increased in the third case study region. We suggest that regionalized food processing is an integral element of circular food systems, as it plays an important role in closing local and regional cycles of nutrients, food, and energy.
