“…Poultry population in Bangladesh is estimated about 304.17 million where chicken population is about 255.31 million (Hamid et al, 2017). Also, it is estimated that approximately 1,560,000 metric tonnes of poultry waste is produced in Bangladesh each year (Miah et al, 2016). Analysis has shown that poultry litter contains potentially valuable plant and animal nutrients, including nearly 30 percent crude protein and high levels of minerals and some heavy metals (Zinn et al, 1996).…”

Poultry manure is a hazard to the environment and health due to the release of toxic substances as well as pathogenic microorganisms. The present study was undertaken to assess the current scenario of poultry waste management considering its social as well as environmental and health hazards. A questionnaire based survey was conducted in 36 commercial poultry farms (which included 15 broiler, 14 layer, 3 cockerel and 4 mixed farms) in Mymensingh district from February to June 2016. Most of the broiler and layer farms had between 500 to 2000 birds, while most of the cockerel farms had between 3000 to 4000 birds. The study showed that 69 percent of the poultry farmers were unaware of the health and environmental problems of the poultry waste. Majority of the small scale farmers disposed their droppings to fish ponds (31 percent) and agricultural farms (16 percent) directly, while only 6 percent farmers used those droppings in biogas plant. However, 53 percent farmers had knowledge about hygienic handling of poultry dropping, although only 19 percent of them used protective gloves during dropping handling. The profitability analysis revealed that average variable cost and fixed cost per farm per year were TK. 2,17,355 and TK. 3,93,106, respectively. The benefit cost ratio per farm per year poultry farming was 1.55. Considering the findings, it is suggested that proper poultry waste management could be highly beneficial for the farmers. On the other hand, improper dispose of poultry litter could be a cause for social, environmental and public health hazard. J. Bangladesh Agril. Univ. 17(1): 50–57, March 2019

“…By comparison, the optimum pH for AD is generally in the range 6.5 to 8.0 77,78 . It has been probed that if this parameter is regulated before and during AD, the methanogenesis process could be improved and better biogas production could be achieved 79 . The problem represented by the high pH of PL is closely related to the inhibition by N. During AD at high pH there is a shift of the equilibrium from free NH 3 to ionised (NH 4 + ) ammonia, which is identified as the main cause of inhibition 80 …”

Poultry litter (PL) is one of the drier and bulkier manures produced in intensive agriculture. Land spreading is considered the most common treatment option for PL; however, this causes large atmospheric greenhouse emissions and consequently a high negative environmental impact. PL has several factors that limit its sustainable use as an energy source, and thus there is still a need for more studies about sustainable waste management. The paper aims at: (i) proposing sustainable pathways in order to maximise the PL valorisation process, based on previous experiences described in the literature; and (ii) showing the advantages of reforming poultry farms into biorefineries in Cuba. Combinations of techniques are used to increase PL valorisation, but only by modulating the theoretical data has an improvement occurred. In this work, pathways for thermo‐ and bioconversion processes are proposed which involve four major technologies for converting PL into useful energy and fertiliser, being pyrolysis/gasification, hydrothermal carbonisation and anaerobic digestion as key conversion technologies. Including technologies for nutrient recovery in the proposed pathways would allow better agricultural applications. The treatment of PL in biorefineries in Cuba would have a positive impact on the economy through income generation and savings resulting from reductions in imports (i.e. fossil fuels and agrochemicals), employment creation, improved living conditions and development in rural communities. Future studies should be aimed at evaluating the various proposed pathways in order to maximise the PL valorisation process, in addition to a marketing study of the products generated through the biorefineries at poultry farms. © 2020 Society of Chemical Industry (SCI)

“…The fermentation process in which a variety of different substances are added and mixed is called co-fermentation. The range of waste with a potential application for the biogas production process is very extensive (Miah et al, 2016;Curkowski, Oniszk-Popławska, 2010). Substrates are used in various forms, volume ratios and at different temperatures during biogas production in a biogas plant.…”

One of the basic aspects of sustainable development strategy involves investments in green technologies, including energy production from renewable sources. Biomass, special organic waste which belongs to “green sources” of energy can be used in the methane fermentation process of biogas production to generate heat and electricity.Biogas power plants have functioned in the Polish energy industry for many years now. On the basis of the data available from Central Statistical Office, in 2014 the ratio of biogas accounted for 7.6% of the structure of primary energy derived from renewable sources in the EU and 2.6% in Poland. An important consideration related to the production of biogas is associated with the applicability of waste resources derived from agricultural production and from the food industry, including pig slurry, slaughterhouse waste, brewing and distilling dregs as well as others. The operation of biogas plants provides considerable benefits to the environment, resulting from the controlled fermentation process and its application in the production of useful energy, as it can provide reduction of the emission of methane and other greenhouse gases. The aspects including the reduction of the volume of waste, environmental protection, fulfillment of the EU obligations and local energy security, form the reasons why communes in Poland should focus their attention on the use of biogas.This paper presents the results of SWOT analysis of biogas production in the context of sustainable development. The assessment of the aspects (strengths, weaknesses, opportunities and threats) and the intensity of their impact were undertaken on the basis of a point scale developed by the authors. The analysis shows that the process demonstrates a number of strengths, which can promote the implementation of positive changes in the environmental and social aspects undertaken on a local scale.
