Coupling economic and GHG emission accounting models to evaluate the sustainability of biogas policies

Spatial Economic Modeling of the Waste-driven Agricultural Biogas in Lubelskie Region, Poland

“…Ascending order of sorghum prices generate the growth of the supply and the decrease of the demand. Following the approach introduced by Delzeit et al [20], [22] and readapted by Bartoli et al [21], [32], market clearing prices and quantities are displayed at the equilibrium, when the supply from the agricultural sector matches the demand from the biogas industry sector, leading to the optimal number and size of simulated biogas plants. The so obtained PE model is run for all scenarios set in Section 3.…”

“…Although across Europe the most common energy crop used for biogas production is maize silage, its cultivation requires intensive use of agricultural resources such as water and fertilizers that may jeopardize the effectiveness of the system in GHG saving [32]. Originated from western Africa, sorghum represents an interesting alternative extensively studied in Europe as energy crop.…”

The Review of Biomass Potential for Agricultural Biogas Production in Poland

“…The operating of agricultural biogas installations is associated with the generation of a large amount of post-fermentation pulp. This product, resulted from the digestion process contains more inorganic nitrogen than non-digested organic fertilizers, and, in consequence, more nitrogen in a form available for plants [88]. Previous studies conducted in EU countries demonstrated the possibility of using the digestate as a replacement for the traditional fertilizer or soil amendment, with the benefits both for the farmers (impact on the crop yields) and soil properties [89][90][91][92][93].…”

“…Nonetheless, due to the growing interest in energy obtained from the agricultural biogas installations in Poland, and consequently, an increased amount of post-digestate pulp attention should be given to the alternative methods of its management. In Italy for instance, the usage of digestate became a key factor to maintain profitability of biogas plants and to promote bioeconomy [88,97].…”

Evaluation of potential feedstocks for sustainable biogas production in Ghana: Quantification, energy generation, and CO 2 abatement

“…There is also global interest in biogas due to the significant role it plays in climate change adaptation attempts and reduction of greenhouse gas effects (Budzianowski, 2012;Igliński et al, 2015). In fact, the World Biogas Association estimates that biogas is among the most effective industry in this respect, as it can contribute to the achievement of 9 out of the 17 Sustainable Development Goals (Bartoli et al, 2019).…”
