“…The time frame adopted in this paper was longer than the 20-year life expectancy of a biogas installation [74]. We estimated previously that, to valorize the sustainable potential of manure for energy alone, up to 1500 agricultural biogas facilities could be necessary [31], 15 times more than today [19]. Considering the future availability of wet biomass resources estimated in this paper, a lot of resources are available.…”

“…Anaerobic digestion has also been identified as one of the most promising practices for mitigating CH 4 and N 2 O emissions from manure storage while producing renewable bioenergy [79][80][81]. In Switzerland, manure could produce 15 PJ of gross biogas yearly, while preventing the emission of 159 kT of CO 2 equivalents compared to emissions under current management practices [31]. Nowadays, manure is hardly used for energy production in Switzerland and is directly applied to fields.…”

“…The energetic content of the farmyard manure produced (current value, no time series [33], with an SD ±2.5% by 2035 and ±5% by 2050, as it varies according to animal breed, stabling system, and feed, which could change over time [31]).…”

In the energy sector, decisions and technology implementations often necessitate a mid- to long-term perspective. Thus, reliable assessments of future resource availability are needed to support the decision-making process. In Switzerland, similarly to other countries, only a limited part of the available wet biomass feedstock is currently used for anaerobic digestion. Understanding potential future trajectories of the available biomass amount is therefore essential to facilitate its deployment for energetic use and to establish adequate bioenergy strategies. Here, we utilized extensive government data, historical trends, and data from academic literature to identify relevant drivers and their trends. Starting with current biomass potential, the future availability and variation of resources was estimated by taking into account selected drivers and their projected future development. Our results indicated an increase of over 6% in available wet bioenergy resources by 2050 (from 43.4 petajoules (PJ) of primary energy currently to 44.3 PJ in 2035 and 45.4 PJ in 2050), where a Monte Carlo analysis showed that this projection is linked to high uncertainty. Manure remains by far the biomass with the largest additional potential. Possible consequences regarding the country’s pool of biogas facilities and their development are discussed.

“…Besides, there were many researches on estimation of green house gases emission from manure treatment and ultilization methods. For example, Vanessa Burg et al [11] assessed the energy and greenhouse gas (GHG) emissions benefits of using manure for biogas, considering its spatial distribution in Switzerland; S. Wei et al [12] calculated the inventories of GHGs and NH3 emissions for periurban livestock production in Beijing; Ngwa M. Ngwabie and Bren N. Chungong [13] measured manure parameters and to subsequently model CH4 emissions in pig fattening barns with slated and concreted floors in Cameroon.…”

To assess the status of manure generation and management practice in household pig farming, the research was implemented in Ha Hoa district, Phu Tho Province. The used research methods were field survey, direct interview with households, experiment establishment to determine daily manure discharged from the different types of pigs (sow, porker, immature pig and piglet). Results showed that the average amount of manure generated per pig was 0.99 kg/day including piglets and 1.3 kg/day excluding piglets. The total amount of pig manure generated in the whole district was 80.7 tons/day. At the scale under 30 pigs, the ratio of pig farming households had waste treatment system to be 16%, partial treatment system to be 46% and not treatment system to be 38%; At the scale larger than 30 pigs, the ratio of pig farming households had waste treatment system to be 76%, partial waste treatment system to be 21% and not waste treatment to be 3%. In the whole survey area, the ratio of pig farming households had with, without and partial manure treatment system to be 46%, 21% and 33%, respectively. The study also suggested suitable solutions for pig waste management especially suitable technical solutions for different scale of pig farms in Ha Hoa district, Phu Tho province.

The rapid growth of organic solid waste has recently exacerbated environmental pollution problems, and its improper treatment has led to the loss of a large number of biomass resources. Here, we expound the advantages of microbial agents composting compared with conventional organic solid waste treatment technology, and review the important role of microbial agents composting in organic solid waste composting from the aspects of screening and identification, optimization of conditions, mechanism of action, combination with other technologies and ultra‐high‐temperature and ultra‐low‐temperature microbial composting. We discuss the value of microorganisms with different growth conditions in organic solid waste composting, and put forward a seasonal multi‐temperature composite microbial composting technology. Provide new ideas for the all‐round treatment of microbial agents in organic solid waste in the future. © 2024 Society of Chemical Industry.
