“…For instance, ammonia emissions from digestate higher than from original manure have been observed in several studies. [56,59,60] It was also reported that up to 30% of nitrogen can be lost by ammonia volatilization, due to the enhancement of soil pH. [59,60] Specifically, Matsunaka and co-workers [61] reported a 13% nitrogen volatilization as ammonia, when anaerobically digested cattle slurry was used as soil fertilizer for grassland.…”

[59,60] Specifically, Matsunaka and co-workers [61] reported a 13% nitrogen volatilization as ammonia, when anaerobically digested cattle slurry was used as soil fertilizer for grassland. The practice of fertilizing soil with anaerobically digested materials increases soil concentration of NO 3 ¡ (C30/40% compared to raw cattle slurry): this is associated to the four times more readily degradable organic C increased microbial biomass, depleting nitrogen and oxygen concentration in soil and resulting in the 10 times increase of CO 2 and N 2 O emissions.…”

The social acceptance of biogas is often hampered by environmental and health concerns. In this study, the current knowledge about the impact of biogas technology is presented and discussed. The survey reports the emission rate estimates of the main greenhouse gases (GHG), namely CO, CH and NO, according to several case studies conducted over the world. Direct emissions of gaseous pollutants are then discussed, with a focus on nitrogen oxides (NO); evidences of the importance of suitable biomass and digestate storages are also reported. The current knowledge on the environmental impact induced by final use of digestate is critically discussed, considering both soil fertility and nitrogen release into atmosphere and groundwater; several case studies are reported, showing the importance of NH emissions with regards to secondary aerosol formation. The biogas upgrading to biomethane is also included in the study: with this regard, the methane slip in the off-gas can significantly reduce the environmental benefits.

“…Furthermore, according to Boulamanti et al (2013), the release of ammonia and leaching of nitrate are more critical issues to be resolved than N 2 O and CH 4 emissions. Nearly 30 percent of nitrogen will be lost by ammonia volatilization due to soil pH enhancement (Ghoneim et al, 2008). Application of digested slurry to soil increases the concentration of NO 3 − in soil by 40 percent than cattle manure, but this results in increased CO 2 and N 2 O emission by tenfold ( Johansen et al, 2013).…”

Purpose It is well known that sustainability is the ideal driving path of the entire world and renewable energy is the backbone of the ongoing initiatives. The current topic of argument among the sustainability research community is on the wise selection of processes that will maximize yield and minimize emissions. The purpose of this paper is to outline different parameters and processes that impact the performance of biogas production plants through an extensive literature review. These include: comparison of biogas plant efficiency based on the use of a diverse range of feedstock; comparison of environmental impacts and its reasons during biogas production based on different feedstock and the processes followed in the management of digestate; analysis of the root cause of inefficiencies in the process of biogas production; factors affecting the energy efficiency of biogas plants based on the processes followed; and the best practices and the future research directions based on the existing life cycle assessment (LCA) studies. Design/methodology/approach The authors adopted a systematic literature review of research articles pertaining to LCA to understand in depth the current research and gaps, and to suggest future research directions. Findings Findings include the impact of the type of feedstock used on the efficiency of the biogas plants and the level of environmental emissions. Based on the analysis of literature pertaining to LCA, diverse factors causing emissions from biogas plants are enlisted. Similarly, the root causes of inefficiencies of biogas plants were also analyzed, which will further help researchers/professionals resolve such issues. Findings also include the limitations of existing research body and factors affecting the energy efficiency of biogas plants. Research limitations/implications This review is focused on articles published from 2006 to 2019 and is limited to the performance of biogas plants using LCA methodology. Originality/value Literature review showed that a majority of articles focused mainly on the efficiency of biogas plants. The novel and the original aspect of this review paper is that the authors, alongside efficiency, have considered other critical parameters such as environmental emission, energy usage, processes followed during anaerobic digestion and the impact of co-digestion of feed as well. The authors also provide solid scientific reasoning to the emission and inefficiencies of the biogas plants, which were rarely analyzed in the past.

“…The removal of these weeds produces large amounts of fresh biomass, causing other problems in its disposal and management (Gusain & Suthar, 2017). Meanwhile, Kanwal et al, (2011) stated that Pistia has a nutrient content of 49.3% C, 2.95% N, 0.57% P, 4% K, 103.6 ppm Zn, 19.03 ppm B in leaf, and 17.08 ppm B in the root. This weed is called a high-quality organic material, due to its high N content and low C / N ratio, with a faster decomposition process.…”

Pistia has no economic value. However, when mixed into straw compost, it tends to enhance its quality. Therefore, this study aims to determine how the Pistia mixture can improve the straw compost quality, thereby increasing rice production. The treatments consisted of soil (control) in values of P100, P75 + J25, P50 + J50, P25 + J75, J100, and NPK. The quality of compost observed was: N, P, K, C/N, lignin, polyphenols, cellulose, and organic matter content. N cumulative and N mineralization rate observed in the second stage was carried out at the incubation 1, 2, 4, and 8 weeks, N mineralization, N uptake, N absorption efficiency, growth, and yield as variables observed in the third stage. This research was conducted to determine the effect of adding a compost mixture with Pistia and straw towards the efficiency, growth, and production of upland rice plants. The results showed that the more Pistia mixed in the straw, the better the compost quality, growth, and yield above J100. N uptake was associated very strongly with the number of panicles and total dry weight of the plant.
