“…They are dark-coloured, still have offensive odour; when diluted in water there are no chemical back reaction or gas discharges. After being applied on agricultural arable areas they quickly become subject to further biological decomposition by aerobic bacteria up to the stage of plant nutrient, which in addition to plant nutrition has very favourable influence on microbiological activity in soil [19,1,20,21,22]. *** *** *** *** Y × S *** *** *** Y × C *** *** *** *** H × S ** *** *** H × C *** *** *** *** S × C *** *** *** Y × H × S *** *** *** Y × H× C *** *** *** *** Y × S × C *** *** *** H × S × C *** *** *** Y × H × S × C *** *** *** The use of digested residues is allowed on plant production surfaces, meadows and plain pastures where soils contain some of heavy metals and persistent organic harmful substances below 50% of marginal values set out under the Regulation on ecological production in plant cultivation and plant products in the Republic of Croatia [23].…”

“…Organic waste is generated from agricultural production, food processing and beverage production or even from domestic waste [1]. Wastes and residues resulting from diverse agricultural activities, such as planting and harvesting of row, field and tree and vine crops, milk production, production of animals for slaughter, and operation of feedlots, are collectively called agricultural waste.…”

Original scientific paper The present paper investigates the effectiveness of different levels of applied digested residue obtained after anaerobic digestion (AD) of meat-bone meal (MBM) on the morphologic and mineral characteristics of corn. The experiment was conducted in duration of two years and consisted of eight treatments: control (without any fertilizer); mineral fertilization only; treatments with minimum, medium and maximum dosage of digested MBM; fertilization of minimum, medium and maximum dosages of AD residue combined with mineral fertilizer. By combination of treatments with mineral fertilizer and different rates of AD residue, plants increased mass yield, they were larger and had more leaves. Content of mineral substances was within average values, both in plant material and in kernel, and variations in values were conditioned by total mass and ion interactions. MBM after AD treatment is possible to be applied as organic fertilizer. It has higher nutritive value and, as such, is suitable for treatment of agricultural plants, especially in crop production. Keywords: anaerobic digestion; corn; fertilization; meat bone meal Anaerobna digestija specifičnog biorazgradivog otpada i konačno zbrinjavanjeIzvorni znanstveni članka Ovaj rad istražuje učinkovitost primjene različitih razina digestiranog ostatka, dobivenog nakon anaerobne digestije (AD) mesno-koštanog brašna (MKB), na morfološka i mineralna svojstva kukuruza. Istraživanje je provedeno u trajanju od dvije godine, a sastojalo se od osam tretmana: kontrola (bez gnojiva); samo mineralna gnojidba; tretmani s najmanjom, srednjom i maksimalnom dozom digestiranog MKB-a; gnojidba minimalnom, srednjom i maksimalnom dozom digestiranog ostatka u kombinaciji s mineralnim gnojivom. Kombinacija tretmana s mineralnim gnojivom i različitom dozom ostatka anaerobne digestije, povećala je prinos mase biljke, bile su veće i imale više lišća. Sadržaj mineralnih tvari bio je prosječne vrijednosti, kako u biljnom materijalu tako i u jezgri. Varijacije vrijednosti uvjetovane su ukupnom masom i ionskim interakcijama. MKB nakon tretmana AD moguće je primijeniti kao organsko gnojivo. Ima veće hranjive vrijednosti i, kao takvo, prikladno je za tretiranje poljoprivrednih biljaka, posebno u ratarstvu.

“…The effect of concentration of ammonia produced during methane fermentation of fish meal on the decomposition rate of anaerobically fermented wastes is described by Omil, Mendez, and Lema [15]. During methane fermentation of poultry litter (domestic fowl) one can observe a characteristic longer period of the lag phase, which can last as long as nine days [16]. The higher the poultry litter and protein content in the anaerobically fermented mixture, the longer this accommodation phase [17].…”

A large amount of litter is generated in industrial-scale animal breeding, and this is recognized as a big problem in animal-breeding technology. Troublesome waste may, however, be regarded as a useful, easily accessible cosubstrate for the production of biogas and semi-liquid residue suitable for fertilizing plants. Its utilization problem can thus be integrated with the production of an environmentally friendly energy carrier: biomethane. The results of litter decomposition are visible just after excretion as odor compounds are emitted. Animal litter of high protein concentration and moisture >40% undergoes complex biochemical decomposition that is closely related to the intensive emission of ammonia. It directly affects living conditions of animals in rooms [1]. The amount and composition of the gaseous mixture produced from litter depends, among other things, on: temperature, moisture level, mixing frequency, bedding type, composition and Pol. J. Environ. Stud. Vol. 26, No. 3 (2017) AbstractThe recommended process conditions and problems reported during anaerobic (co-)fermentation of waste biomass rich in proteins are discussed. Theoretical potentials of the individual biogas components (CH 4 , CO 2 , NH 3 , H 2 S) formed during chemical decomposition of aminoacids -feed additives commonly used in feeding animals -are shown, and we discuss side production of odors, e.g., ammonia and organic sulphur compounds. We also suggest the potential alternative production of biohydrogen (a future energy carrier) from specific waste biomass with high protein content.

“…Landfill gas is produced by wet organic matter decomposing anaerobically in a landfill whereas digester gas is produced by using an anaerobic digester generally referred to as biogas plant. Anaerobic digesters can be designed and constructed based on a number of different process variables or configurations such as batch-or continuous-process; mesophilic-or thermophilic-conditions; high-or low-solid content and single stage-or multistage-complexity (Nagamani and Ramasamy, 2011;Callaghan et al, 1999). The biochemical processes that take place in a typical digester are classified into four distinct and sequential stages namely, hydrolysis, acidogenesis, acetogenesis and methanogenesis (Bailey and Ollis, 1977;Smith, 1980;Sans et al, 1995;Nagamani and Ramasamy, 2011).…”

“…Others are concentration of slurry, total solid content, agitation of slurry, volatile fatty acids and amount of water in the slurry. The pH of the biogas plant is a function of the amount of CO 2 produced, HCO 3 -alkalinity of the medium and concentration of volatile fatty acids produced (Bailey and Ollis,1977). For increased biogas yield a pH of 6.6 to 7.6 is adequate (Bailey and Ollis, 1977).…”
