“…While the biogas generated in AD is often only considered for electricity generation or even sometimes being directly flared, the value and scope of biogas applications can be largely upgraded by eliminating carbon dioxide and other contaminant gases to provide high-quality biomethane as a substitute for natural gas in various industrial and domestic uses [99][100][101][102][103]. Biogas from AD cannot be only considered alongside as the same arrays with solar or wind power as sustainable energy.…”

Municipal solid waste (MSW) management has emerged as probably the most pressing issue many governments nowadays are facing. Traditionally, Waste-to-Energy(WtE) is mostly associated with incineration, but now, with the emergence of the bioeconomy, it embraces a broader definition comprising any processing technique that can generate electricity/heat or produce a waste-derived fuel. Under the ambit of the circular economy many nations are looking for, additional effort must be made to be sure of acquiring the most updated information and paving a sustainable path for managing MSW in such a frame. In this regard, we have undertaken a critical review of various technologies, with their updated progress, involved in the exploitation of MSW as a renewable resource, along with the critical advantages and limitations on energy and material cycling for sustainable MSW management. Incineration, the most widely used method, is nowadays difficult to further apply due to its dubious reputation and social opposition. Meanwhile, to address the organic fraction of MSW which currently is mostly unrecycled and causes disposal issues, the biological approach presents an attractive option. The new emphasis of bioeconomy leads us to understand how environmental biotechnologies should be better connected/integrated for more sustainable MSW management. This article is concluded with advances of future prospects, which can serve as a timely reminder to encourage competent authorities/researchers to work towards further improvement of the present MSW management system.

“…The issue of using biomass from residuals is of rising interest in science. In the scientific literature, the current research focus is on technological aspects, such as efficiency and reducing emissions of conversion technologies [20]. Some research exists on the residual feedstock characteristic for the gasification process [21] and for producing biogas [22].…”

Background To prevent negative effects on the cultural landscape through land abandonment or agricultural intensification, innovative solutions towards more sustainable land use are required. Local bioenergy systems using agricultural co-products are perceived as one solution to threatened cultural landscapes with small-scale meadows. The aim of this paper is to analyse the acceptability of biomass heating plants in the Spreewald region (Germany) and their contribution to cultural landscape management. Methods We asked 17 farmers about the likelihood that they would install a biomass plant on their farms and about their reasons for accepting or rejecting it. A fuzzy set qualitative comparative analysis was applied. Results The analysis showed that acceptance is relatively low. We identified three types of farmers: proponents and potential adopters, ethically concerned opponents, and open-minded refusers. Biomass plants were likely to be accepted if farmers stated an ethical acceptance of and interest in technology, a need for a new heating system, the availability of sufficient feedstock, and a perceived unproblematic readiness of technology—all these factors had to exist in combination. On the other hand, farmers rejected a biomass plant if one of the following factors existed: ethical concerns about “burning hay”, satisfaction with their current oven, low availability of feedstock, or a perceived low readiness of technology. Other factors were the existence of procedural justice, trust in coordinating actors, and a demonstration plant. Conclusions The discussion shows that the specific results have to be contextualised within the innovation process for sustainable landscape management. This may be achieved by integrating the acceptability study into an adaptive landscape design. This relies on mutable acceptability decisions, reflexive learning processes, and iterative feedback loops in innovation processes. Our paper advances knowledge about (1) how to prevent land abandonment and simultaneously promote regional energy and (2) the acceptability in the field of land use and landscape management.

“…Lifestock manure is characterized by a large content of such nutrients as nitrogen, phosphorus, and potassium, which are the most required components for plants' growth (Adekiya & Agbede, ; Molaey, Bayrakdar, Sürmeli, & Çalli, ). Additionally, manure contains significant amount of organic compounds that can be successfully decomposed by using anaerobic digesters to produce biogas, which consists mainly of CH 4 (about 40%–65%), CO 2 (about 35%–55%), and H 2 S (about 0.1%–3%) (Ma et al, ; Sahota et al, ; Scarlat, Fahl, Dallemand, Monforti, & Motola, ). Anaerobic digesters (bioreactors) are used for biogas production by decomposing organic biomass.…”

Semi-continuous and periodic biogas production processes were investigated. Dry chicken manure containing 40.0 ± 0.5% volatile solids (VS) was used for the production of bioloading. Semi-continuous operation bioreactor and periodic bioreactor were used to implement research. Bioloading was additionally supplemented with newly prepared parts by removing 10% of decomposed mass and by adding the same amount of preheated mass every 7 days (semi-continuous process). The process was periodic when the mass was completely decomposed (after 45 days of the experiment) and fully removed (bioreactor was loaded with a new portion of raw material to 100% of the working volume again). Total duration of both experiments was 90 days. The results show that biogas production by semi-continuous process is more effective than periodic process due to higher total biogas yield (up to 39.7%) and higher methane yield (up to 33.5%). The maximum concentration of CH 4 was determined during the periodic biogas production process, but the difference was only up to 2.1% (68.9% and 66.8%, respectively). Since the produced biogas had quite high average CO 2 and H 2 S concentrations (<40.0% and 2.1 g/m 3 , respectively), it is recommended to use filter-adsorbers or biofilters. According to the results, semi-continuous type bioreactor is more effective than periodic. • Practitioner points• Maximum CH 4 concentration in biogas, produced during periodic process, is 2.1% higher than during the semi-continuous process. • Average CH 4 concentration in biogas, produced during periodic and semi-continuous process, reaches 52.7% and 53.0%, respectively. • Biogas and methane yield (during periodic process) is 39.7% and 33.5% lower than during the semi-continuous process. • CH 4 concentration decreases (after supplement) about 6.0%-7.0% (during the semicontinuous process), but increases to the next cyclic bioloading supplement. • Semi-continuous biogas production process is more efficient than periodic.
