  • Chicken Skin Wastewater

    The wastewater from a poultry processing plant contained almost exclusively skins, and high concentrations of fat for approximately 8 hours of the production day. This wastewater created heavy blinding problems on their dewatering system. In lab tests the untreated wastewater would completely blind 30 thousands wedge wire screen and inhibit dewatering. IE-614 treated the wastewater with no pH ...

  • Chicken Processing Plant (Ukraine (3))

    In this Chicken Processing Plant, the cost for sludge disposal had been extremely high since they disposed of sludge by tanker truck without sludge dewatering process. Because of the high sludge disposal cost, they had looked for a sludge dewatering equipment suitable for dewatering oily sludge, but could never find a solution. Solution Volute Dewatering Press ES-303 was ...

  • Chicken Manure Management, Recycling, and Composting

    Chicken Manure Fertilizer Manufacturing Process If you have chickens, you will have manure. Fortunately, chicken manure is among the most prized of manures. Fresh chicken manure is considered a “hot” manure, which is unsuitable for immediate use. Chicken manure needs to be composted and aged at least two to three months before you add it to your garden. If you don’t wait ...

  • Removal and recovery of ammonia from chicken manure

    The feasibility of the conversion of organic nitrogen available in raw chicken manure (CM) into ammonia via hydrolysis and the removal of ammonia from anaerobically digested manure were evaluated in this study. Firstly, the hydrolysis experiments were performed and the effects of temperature, total solids (TS) content and retention time were investigated. The results showed that 90% of the ...

  • Nitrogen and sulphur transformations in composts containing chicken feathers

    Chicken feathers composted with pine bark and rye straw are subject to intensive mineralisation and biotransformation with efflux of water-soluble components: N-NH4, N-NO3 and S-SO4. The content of N-NH4, N-NO3 and S-SO4 in water extracts of the studied composts was positively correlated with the time of composting. The release of those components reached a maximum after 15 weeks of composting ...

  • Biodegradation of crude oil in soil using chicken manure

    To investigate enhancement of crude oil biodegradation by adding microbes to the contaminated soil, chicken manure was put into oil-polluted soil (at 10% v/w pollution level). In the soil amended with chicken manure, 72.5% of the crude oil was degraded, whereas only 52.7% of same oil was degraded in the unamended soil. The remedied soil contains 1.4 × 106 CFU g−1 crude oil-degrading bacteria, and ...

  • Chicken Processing Plant in Ukraine - Case Study

    Dewatering of oily sludge without clogging Problem The chicken processing plant in Ukraine had a big issue on tremendous amount of sludge disposal costs due to direct disposal of the sludge without dewatering. They had tried to look for a suitable sludge dewatering equipment for easy dewatering of the oily sludge, however it was almost impossible to find. ...

  • Assessment of shelf-life of irradiated frozen chicken

    Food irradiation is the process of exposing food to controlled source of ionising radiation for the purpose of reduction of microbial load, destruction of pathogens and extension of product shelf-life. Detection and measurement of irradiation dose in food are an essential element of food safety and quality. This study aimed to estimate shelf-life of chicken samples which have been stored frozen ...

  • Microstructural characterisation of keratin fibres from chicken feathers

    Natural fibres have recently attracted scientists' attention because of their advantages from the environmental standpoint. However, almost all the research has been directed towards cellulose from vegetal sources without taking into account other potentially interesting compounds like keratin, which can be found in feathers, wool, nail or hair. In spite of its strength, low density and ...

  • Take action to stop Chinese chicken imports

    In August of 2013 the New York Times reported that the U.S. Department of Agriculture (USDA) gave the green light to four Chinese poultry processors to ship processed poultry to the United States. The move was aimed to only ...

  • Protein from preprocessed waste activated sludge as a nutritional supplement in chicken feed

    Five groups of broiler chickens were raised on feed containing varying substitutions of single cell protein from preprocessed waste activated sludge (pWAS) in varying compositions of 0:100, 25:75, 50:50, 75:25, and 100:0 pWAS: fishmeal by mass. Forty chickens per batch were evaluated for growth rate, mortality rate, and feed conversion efficiency (ηє). The initial ...

  • The chicken or egg problem revisited: the role of resources and incentives in the integration of biotechnology techniques

    During the last 15 years, most countries of the developing world have declared investment in biotechnology to be strategic to their national programs of development and yet none of them has attained an industrial competence in the biotechnology sectors comparable to that of the developed nations. Is it simply a question of inadequacy of resources or is there something more to the building of ...

  • Low-tech options for chicken manure treatment and application possibilities in agriculture

    SUMMARY: Problems related to chicken manure disposal are a relevant issue in many countries of Asia due to the constantly increasing demand for chicken products. An application without treatment or non-appropriate disposal can become risky for environment and humans. Simple treatment techniques which convert the manure into valuable fertilizer are needed. A low-tech option is currently under ...


  • Evaluation of composting performance of mixtures of chicken blood and maize stover in Harare, Zimbabwe

    Background: Chicken processing results in the production of a lot of blood which if disposed on land poses environmental hazards in terms of land pollution. The aim of the study was to develop an aerobic composting process for chicken blood to produce a nitrogen-rich soil amendment for use in agriculture. The study involved composting of blood and maize stover of different proportions (10%, 30%, ...

  • Simple way to reduce costs and increase profit a case study in chicken processing

    Packaged-food producers frequently use and then must discard large batches of cooking oil used in their process. Usually they drain most of the oil directly from equipment, but they must remove residual oil by regularly washing fryers, ovens, conveyors, and other machinery. The oil mixes with the wash water and becomes part of the plant’s wastewater stream. Having oil in wastewater complicates ...

  • Chicken waste could produce unexpected energy windfalls in Ukraine

    Ukrainians soon could enjoy a new windfall of electricity and heat from an unexpected source – chickens. In some unusual news, the Swiss company Alter Energy Group AG is assessing Ukrainian poultry farm sites to implement a sophisticated waste to energy process. The process takes chicken and poultry manure and turns it into clean, environmentally safe, industrial scale electricity and heat. This ...

  • Metal distribution in tissues of free‐range chickens near a lead–zinc mine in Kabwe, Zambia

    Concentrations of Pb, Cd, and other metals in tissues of 17 free‐range and 32 commercial broiler chickens from the Kabwe mining town in Zambia were determined. Mean concentrations of Pb and Cd exceeded maximum levels for human consumption in some organs including muscle (Pb only) in free‐range chickens, in contrast to low levels in broiler chickens. Human consumers in Kabwe could be exposed to ...

  • Halogenated flame retardants during egg formation and chicken embryo development: Maternal transfer, possible biotransformation, and tissue distribution

    Hen muscle, eggs, and newborn chick tissues (muscle and liver) were collected from an electronic waste recycling site in southern China. The authors examined the maternal transfer, potential metabolism, and tissue distribution of several halogenated flame retardants (HFRs) during egg formation and chicken embryo development. The pollutant composition changes significantly from hen muscle to ...

  • Bisphenol S alters embryonic viability, development, gallbladder size, and mRNA expression in chicken embryos exposed via egg injection

    Amid concerns about the toxicological effects and environmental prevalence of bisphenol A (BPA), efforts to find suitable, safer replacement alternatives are essential. Bisphenol S (BPS) is one potential chemical substitute for BPA; however, few studies are available confirming it has a more desirable ecotoxicological profile. In the present study, BPS was injected into the air cell of ...
