1.2. Production Costs
- To avoid inconveniences, nuisances, and disputes linked to odors and increased traffic to and from the biogas plant, the site must be located at a suitable distance from populated areas.
- The direction of the prevailing winds must be taken into account to avoid wind-borne odors reaching populated areas.
- The area must have easy access to infrastructure, such as the electricity grid, to facilitate the sale of electricity, and transport routes to facilitate the transportation of raw materials and recycled digestate.
- Before starting construction, the soil of the area must be examined.
- The potential area must not be located in flood-affected areas.
- The area must be relatively close (centrally located) to agricultural raw materials (manure, slurry, energy crops) to reduce the transportation of raw materials distances, time, and costs.
- Due to cost efficiency, the biogas plant should be located as close as possible to the potential heat consumers. Alternatively, other potential heat consumers may be transferred, such as plants, greenhouses, etc., closer to the biogas plant site.
- The size of the site must be sufficient for the activities carried out and the amount of biomass supplied.

4. Conclusions
- Total biomethane potential from processing livestock manure, wastewater sludge, and municipal organic food waste in Latvia is 2.21 to 4.28 PJ.
- 91% of biomethane potential comes from processing livestock manure, out of which ~61% share is from processing dairy cow manure. Emission savings from using livestock manure as feedstock for biomethane production is calculated to be 209%.
- If all the biomethane potential would be used in the transport sector, potentially 4.07–7.88% of total energy could be replaced, and total transport emissions would be with renewable biomethane. Total transport emissions would be 8.06–15.43% less.
- If diesel fuel would be replaced with renewable biomethane, potentially 6.30–12.19% of diesel could be replaced, and emissions would be reduced by 12.47 to 23.86%.
- If all the biomethane potential would be used in the transport sector replacing fossil fuel, 0.4–0.8 million tonnes of CO2-eq emissions could be avoided, and if the current total biogas station energy would be used combined with the total biomethane potential, 1.0–1.4 million tonnes of CO2-eq emissions could be avoided.
