“…First order model include a kinetic constant 'k' which denotes the rate of biogas production. More positive inclination of k denotes faster rate of biogas production [26]. In the present study, the value of k was found to be 0.049 d -1 which is similar to the reported range of 0.017-0.04 d -1 [25].…”

“…Both of these resources in general represent food security [71]. However, their residues can also be used for other products, such as biogas (e.g., [72]) and fish/animal feed (e.g., [73]). The potential of access to fish and plants for furthering a bioeconomy we would argue lies in their dual-usage potential in a circular bioeconomy [74].…”

Developing a future bioeconomy has become critical for three main reasons: (1) The need for sustainability of resource use; (2) The growing demand for both food and energy; and (3) The need to decouple economic growth from environmental degradation. As Zilberman observes, a transition to bioeconomy "is a continuing evolutionary process of transition from systems of mining non-renewable resources to farming renewable ones". Hence, to meet the challenges created by a growing dependence on non-renewable resources, radical changes are needed that involve more than development of or changes within the individual bio-based sectors. In line with emerging attention to the bioeconomy in Europe and elsewhere, great expectations towards the bioeconomy have been launched in high level industry and policy fora, as well as in resource-based economies such as Norway's. Grounded in theories of transition and transition management, this paper discusses the Norwegian biosector's expectations regarding a bioeconomy. Analyses are based on empirical survey data from biosector representatives. Findings suggest that there are clear differences between sectors in motivation for a future bioeconomy. A transition into a complete bioeconomy will demand a system shift and more cross-sectoral integration between these regimes than currently exists.

Purpose:The objective of this study was to measure emissions of gases (ammonia (NH3), hydrogen sulfide (H2S) and carbon dioxide (CO2)), volatile organic compounds (VOC) and odor from two shallow pit pig nursery rooms. Gas and odor reduction practices for swine operations based on the literature were also discussed. Methods: This study was conducted for 60 days at a commercial swine nursery facility which consisted of four identical rooms with mechanical ventilations. Two rooms (room 1 (R1) and room 2 (R2)) with different pig numbers and ventilation rates were used in this study. The pig manure from both the R1 and R2 were characterized. Indoor/outdoor temperatures, ventilation rates/duration, NH3, H2S, CO2, and VOC concentrations of the ventilation air were measured periodically (3-5 times/week). Odor concentrations of the ventilations were measured two times on two days. Three different types of gas and odor reduction practices (diet control, chemical method, and biological method) were discussed in this study. Results: The volatile solids to total solids ratio (VS/TS) and crude protein (CP) value of pig manure indicated the pig manure had high potential for gas and odor emissions. The NH3, H2S, CO2 and VOC concentrations were measured in the ranges of 1.0-13.3, 0.1-5.7, 1600-3000 and 0.0-1.83 ppm, respectively. The NH3 concentrations were found significantly higher than H2S concentrations for both rooms. The odor concentrations were measured in the range of 2853-4432 OUE/m 3 . There was significant difference in odor concentrations between the two rooms which was due to difference in pig numbers and ventilation duration. The literature studies showed that simultaneous use of dietary control and biofiltration practices will be more effective and environmentally friendly for gas and odor reductions from pig barns. Conclusions: The gas and odor concentrations measured in the ventilation air from the pig rooms indicate an acute need for using gas and odor mitigation technologies. Adopting diet control and biofiltration practices simultaneously could be the best option for mitigating gas and odor emissions from pig barns.
