“…6.2 million m³/a can be estimated based on the national average values for manure (FNR, 2022c). Electricity and heat can be obtained from manure in biogas plants, and the digestate can be used as fertilizer after the process (Cai et al, 2019;Anacleto et al, 2022). A sustainable operation of biogas plants needs to ensure recycling management and avoid over-fertilization (Sommer and Knudsen, 2021).…”

Coal has been one of the main fuels used in Europe. Its decreasing role due to the ongoing transformation of the energy system will create significant socio-economic challenges. The switch into renewable energy systems could be an alternative to maintain jobs and economic activities within the affected regions. Biomass use and bioenergy can play an important role in the energy transition. Instead of energy crops, forest and agricultural residues should be used as biogenic energy sources in the future to avoid impacts on land use and food security. The main objective of this article is to investigate the biomass potential of a coal region and to provide scenarios for the future development of bioenergy production. Due to the changing framework conditions and, as a result, the different biomass focuses, previous bioenergy potential estimates must be reviewed. The methods for determining the potential of biomass for energy production was used for Lusatia (in German: Lausitz), the second largest coal region in Germany. These methods can also be applied in other regions. As a first step, the regional status quo assessment of cultivated areas and yields had decisive relevance for calculating biomass potential ranges. In a second step, the current bioenergy facilities in the region were identified, with a focus on power and heat production. The third step was the estimation of future regional bioenergy use. Therefore, the regional potential was gathered with the generally supra-regional framework conditions. For this purpose, national scenario studies were used, which contain the relevant target values and framework conditions. Two scenarios were developed for future bioenergy estimations: a conservative path based on the current policies and a progressive path, derived from the goal of climate neutrality by 2045. The results show a qualitative comparison among both scenarios and the previously determined potential ranges. Bioenergy can probably contribute to achieving climate neutrality with an increase in wood-fired systems, while agricultural bioenergy potential is likely to decline. In the discussion section, however, the uncertainty of these results is pointed out, as future use of bioenergy will be heavily influenced by the regulatory framework, competition with material use and the influences of climate change.

“…Manure is a valuable natural fertilizer, but, at the same time, its improper management contributes to harmful GHG emissions and odor-generating ammonia [11][12][13]. This promotes acidification and the formation of particulate matter, primarily as a result of the volatilization of ammonia and nitrogen oxides, as well as the eutrophication that is largely related to leaching of nitrates and phosphates from surface waters and soil [14][15][16]. Manure management, including agrotechnical treatments, often leads to considerable costs, but above all, to the consumption of valuable fossil energy sources [14,15,17].…”

Manure management, including agrotechnical treatments, often leads to considerable costs, but above all, to the consumption of valuable fossil energy sources [14,15,17]. To reduce these costs, relatively cheap solutions can be employed, including compaction and heap cover [18][19][20], solid fraction separation [18,19,21,22], composting [23][24][25][26][27][28][29][30][31][32], and others [19,33,34].…”

“…Although almost 60% (ranging from 30 to 75% depending on the country) of biomass is used in animal production (as feed or bedding [44]), only a few percent of this stream goes to biogas units and, although this share is still growing, this growth is very slow [41,[45][46][47]. There are several reasons for this situation, including low biogas efficiency with a minor degree of organic degradation, mainly due to the high water and fiber content [14,[48][49][50], the need to build large-capacity sealed tanks to store the resulting digestate [39], and lack of a sufficiently large and well-balanced (carbon to nitrogen ratio, organic or lignocellulose content, humidity, etc.) resource of substrates for year-round protection of the biogas plant feedstock [51][52][53][54].…”

Currently, there is an ongoing intensive search for solutions that would effectively reduce greenhouse gas emissions (mainly methane) into the environment. From a practical point of view, it is important to reduce methane emissions from cows in such a way as to simultaneously trim emissions from the digestive system and increase its potential production from feces, which is intended as a substrate used in biogas plants. Such a solution would not only lower animal-based methane emissions but would also enable the production of fuel (in chemical form) with a high yield of methane from biogas, which would boost the economic benefits and reduce the use of fossil fuels. We tested the effect of administering an essential oil blend consisting of 5.5% oils and fats on methane and biogas production from dairy cow feces during fermentation. Three subsequent series (control and experimental) were conducted in dairy cows fed a total mixed ration (TMR) rich in brewer’s cereals and beet pulp, with 20% dry matter (DM) of the total diet. Cows from the experimental group received 20 g/cow/day of essential oil blend, namely a commercial additive (CA). The study showed that CA can increase the production of methane and biogas from dairy cow feces. It can be concluded that in the experimental groups, approx. 15.2% and 14.4% on a fresh matter basis and 11.7% and 10.9% on a dry matter basis more methane and biogas were generated compared to the control group, respectively. Therefore, it can be assumed that the use of CA in cow nutrition improved dietary digestibility, which increased the efficiency of the use of feces organic matter for biogas production.

“…Several studies have suggested that the application of pretreatments is advantageous not only to improve organic matter degradability, but also to increase the biogas yield [10][11][12][13] and further remove dyes and toxic compounds from wastewater and solid waste from aqueous solutions [4,10]. Pretreatments can be chemical, physical, biological, or combinations of these, and their performance is influenced by the chemical composition of the waste [14].…”

The textile industry is one of the largest environmental polluters in the world. Although waste management via anaerobic digestion (AD) is a sustainable strategy to transform waste into clean energy and water recovery, the efficiency of the AD process is reduced by the presence of recalcitrant materials, chemicals, and toxic contents. This study aims to investigate the performance of several chemical, physical, and biological pretreatments applied to improve the biodegradability of textile waste. We performed a meta-analysis with 117 data extracted from 13 published articles that evaluated the efficiency of pretreatments applied to textile waste prior to AD to increase biogas production measured as methane (CH4) yield. Even though the majority of the studies have focused on the effect of chemical and physical pretreatments, our results showed that the application of biological pretreatments are more efficient and eco-friendlier. Biological pretreatments can increase CH4 yield by up to 360% with lower environmental risk and lower operating costs, while producing clean energy and a cleaner waste stream. Biological pretreatments also avoid the addition of chemicals and favor the reuse of textile wastewater, decreasing the current demand for clean water and increasing resource circularity in the textile industry.
