Acidic Nature

According to the Federal Waste Classification Catalogue swine manure and slurry are classified as hazardous wastes of class 3. When stored these wastes emit various gases into the atmosphere including greenhouse gases. It is possible to solve this problem by using a chemical approach. For binding pollutants of acidic nature it is proposed to use sodium hypochlorite showing the properties of bases, while for the substances having basic properties it is possible to use sulfuric acid. The distinctive feature of this method is the technology of using the wastes of chemical industry. This paper proposes and justifies the technological scheme of the chemical method for cleaning the air polluted by emissions from industrial pig enterprises. The research was performed under laboratory conditions, taking into account the technological specifics of pig industry. In the course of the study, gravimetric and potentiometric methods were used. The object of the study was native manure obtained from 4-month-old pigs. In the experiment, we used waste sulfuric acid and alkaline solution of sodium hypochlorite produced By "HaloPolymer Kirovo-Chepetsk". The handbook of best available methods in pig industry recommends using low-waste technologies, while it is possible to use waste products from local chemical enterprises for recycling agricultural waste. The technological solution will make it possible to reduce the concentration of odorigenic substances in the air of livestock premises, to eliminate odors from ventilation emissions, to reduce the toxicity of manure effluent and to process toxic fresh pig manure into granular organic fertilizer. The introduction of this scheme into industrial pig farming will dramatically reduce the amount of malodorous animal waste, significantly reduce odor pollution and improve the environmental situation in the areas adjacent to pig farms.

Optimal Approach

A person’s desire to improve the quality of life makes the individual reconsider the attitude towards the quality of consumed food. Despite the fact that the prices of natural products are several times higher than of those grown with the use of herbicides and pesticides, organic food is getting more popular in all countries around the world. Such products can only be received when crops are grown using organic farming methods, one of the principles of which is to increase the amount humus in the soil. The preservation of soil fertility can be ensured using the methods of modern biotechnology, which are based on the vital activity of microorganisms capable of converting organic matter from animal waste into environmentally friendly fertilizers. In animal husbandry, the main portion of agricultural waste is cattle and pig manure. The most economical way to dispose it is to use methane digestion, when biogas and fertilizers are obtained. However, when processing manure bedding materials in biogas reactors, the straw fractions and lignin–containing components of the bedding are not decomposed by bacteria and pass into the solid fraction of the fermented biomass unchanged, which is a problem. The infiltration of such an unprocessed residue into the soil leads to deterioration of soil properties. Thereby, the solid fraction of the fermented biomass requires additional processing to improve its agrochemical properties. Most expedient is to use vermicomposting, that is, process organic waste with the help of earthworms. Biohumus, or vermicompost, is one of the end products of this method. In this work, we studied the procedure of processing the solid fraction of fermented pig manure by Eisenia foetida compost worms (red Californian worm). In order to determine the optimal approach of vermicomposting, the experiment was planned. As a result, a high–quality organic fertilizer was obtained – biohumus –and the optimal parameters of the environment were determined(pH and humidity), at which the worms have the highest biological activity.

We report the use of bacteriophages for control of Salmonella Enteritidis in poultry production. Phage was isolated by the double-agar plate assay from agricultural waste samples, and one isolate, named SM1, was selected and propagated for application in poultry litter. Two experimental protocols were tested: single treatment and repeated treatment (re-application of phage SM1 after 6 h and 12 h). Each treatment cycle involved 25 g of poultry litter placed in plastic boxes and contaminated with 105 Colony Forming Units mL−1 (CFU mL−1) of S. Enteritidis, in independent duplicates. The contaminated litter was treated with 106 Plaque Forming Units mL−1 (PFU mL−1) of SM1 phage by dripping. Repeated application of phage SM1 reduced Salmonella counts by over 99.9%; the phage persisted in poultry litter for over 35 days. This study illustrates the application of SM1 treatment as a promising technology for bacterial control in production matrices that could allow safe and sustainable use of agricultural waste products as biofertilizers.

Reduction of food rations and shortages is one of the impacts of the increasing human population. Food sector industries then try to cope with the fast growing number of customers. Agribusiness sector gains its popularity in these recent years, including pig farm. The increase trend of animal farming industry is likely to bring increasing pollution problem unless effective treatment methods are used. The main problems related to the pig farm include odor nuisance and pig manure disposal. The existing land application of piggery wastewater is the traditional way to discharge the wastewater. This may yield in land and water contamination, due to the accumulation of unused nutrients by crop plant. A case study of a large commercial pig farm from Australia is proposed to apply in smaller scale in Indonesia. Operational strategies for the small-scale SBR (Sequencing Batch Reactor) treating piggery effluent were developed based on lab-scale experiments. Due to SBR characteristics, which are money-saving and space-saving, it is very suitable to be applied in urban area. An economic evaluation was made of various process options. The cost estimation showed that SBR is a cost effective process, allowing operational batches to be adjusted to reduce unnecessary aeration cost. A reduction in the aeration cost was achieved by shortening the batch time from 24-h to 8-h. A comparison of three different SBR options showed that smaller size reactors could be more flexible and cost effective when compared with the larger ones.

Probiotic Properties

Background and Aim: Using antimicrobials as a feed additive in swine production is prohibited because it is a major cause of the emergence of antimicrobial-resistant bacteria. Probiotics such as Lactobacillus spp. are an attractive alternative to reduce antimicrobial resistance and promote swine growth. This study aimed to evaluate the in vitro probiotic properties of Lactobacillus isolated from indigenous swine manure. Materials and Methods: A total of 30 fecal samples from healthy individual indigenous pigs were collected and isolated on de Man, Rogosa, and Sharpe agar. The preliminary screen identified candidates with antibacterial activity against six pathogens and >50% survival and tolerance to acid (pH 3.0) and 1% bile salt. Isolates that passed the initial screen will be tested for other probiotic properties. Results: Of the 314 isolates from 30 pig manure samples, 17 isolates satisfied all initial conditions for probiotic properties. Each isolate has unique, distinctive properties. Isolates B4, B5, B8, B17, B87, and B144 formed thick biofilms, whereas isolates B5, B8, and 27 adhered well to the intestinal wall and exhibited strong autoaggregation properties. Isolate B4 aggregated with Enterohemorrhagic Escherichia coli and Enteropathogenic E. coli. Tests in pH-adjusted cell-free medium indicated that the antibacterial activity resulted from bacterial acidification rather than bacteriocin formation. Sequence analysis (16S rRNA) revealed 16 of the isolates were Lactobacillus plantarum, and only one isolate was Lactobacillus salivarius. Conclusion: We isolated 17 Lactobacillus from swine manure and demonstrated that their probiotic properties might be useful as a probiotic cocktail for swine feed.

Nitrous oxide (N2O) is one of the main gases that contributes to the greenhouse effect. With a Global Warming Potential (GWP) 265 times greater than that of carbon dioxide (CO2), over a 100-year horizon, N2O also has the potential for the depreciation of the ozone layer. The activities related to agriculture and livestock are responsible for approximately 60% of the global anthropogenic emissions of this gas to the atmosphere. In Brazil, the sector corresponds to 37% of total emissions. The objectives of this review article were: (i) To verify which are the main processes involved in N2O emissions in soils fertilized with swine manure; (ii) What are the direct emissions on these soils under different management systems, and; (iii) What are the possible strategies for controlling and mitigating N2O emissions. Therefore, an exploratory and qualitative research of articles was carried out using the following keywords: óxido nitroso’, ‘nitrous oxide’, ‘N2O’, ‘nitrogênio’, ‘nitrogen’, ‘suínos, ‘pig, ‘swine’, ‘dejetos’, ‘manure’ and ‘slurry’. Effects of pig diet, manure treatment systems, presence of heavy metals in the soil and moisture content of manure on N2O emissions were verified. Therefore, we recommend integrated studies of the quantitative and qualitative impacts of the levels and sources of nitrogen in the animals' diets on N2O emissions after the application of these wastes to the soil. We also recommend studies related to the effects of copper and zinc contents added to the soil via swine manure on enzymes that catalyze the biotic denitrification process in the soil.

Municipal Waste Compost

The Circular Economy concept implies the re-design of existing production systems in agriculture, by promoting agricultural waste recycling. In an organic zucchini—lettuce rotation, two different agroecological tools were considered: biofertilizer and presence or absence of green manure (GM+ and GM−). In particular, we compared: (i) anaerobic digestate from cattle manure, co-composted with vegetable wastes, with the presence of GM (AD GM+); (ii) olive pomace compost, re-composted, with the presence of GM (OWC GM+); (iii) municipal waste compost with GM (MWC GM+); (iv) municipal waste compost without GM (MWC GM−). These materials were tested with a commercial organic fertilizer without GM (COF GM−) as a positive control. The objectives were: (i) assessing the environmental sustainability of biofertilizers through carbon footprint analysis by greenhouse gas—GHG—emissions; (ii) evaluating the agronomic performance on the vegetable rotation, by energy output assessment. The total carbon emissions of biofertilizers production was 63.9 and 67.0 kg of CO2 eq Mg−1 for AD and OWC, respectively. The co-composting and re-composting processes emitted 31.4 and 8.4 kg CO2 per Mg of compost, respectively. In AD the ventilation phase of composting accounted for 37.2% of total emissions. The total CO2 emission values for the two-crop cycles were the highest in COF GM− and the lowest in OWC GM+, due to different fertilizer sources. On the average of the treatments, the input that induced the highest CO2 emission was irrigation (37.9%). The energy output assessment for zucchini and lettuce highlighted similar performance for all the treatments. Our findings demonstrated the validity of the tested processes to recycle agro-industrial wastes, and the potential of agroecological practices (GM) to mitigate GHG emissions.

HighlightsThe maximum SCCA concentration was achieved at a C/N ratio of 25 with 18 days of fermentation.The highest VFAs and LA were produced at C/N ratios of 12.7 and 35, respectively, after 12 days of fermentation.The unit energy value of SCCAs for drop-in fuel production was 50.5% higher than that of methane.The dominant bacteria changed from Clostridium to Lactobacillus with increasing C/N ratio.Abstract. Advancing technologies to produce short-chain carboxylic acids (SCCAs) from agricultural waste are expected to be more economical and efficient. This study presented a new attempt to enhance SCCA production from co-digestion of swine manure and corn silage with the carbon-nitrogen (C/N) ratio adjusted from 12.7 to 50.2. Results showed that the maximum SCCA concentration of 26,214 ±2948 mg COD L-1 was achieved at a C/N ratio of 25 with 18 days of digestion, and the concentrations of lactic acid (LA) and volatile fatty acids (VFAs) were 8700 ±1060 mg COD L-1 and 17,514 ±1888 mg COD L-1, respectively. The LA content first increased and then slightly decreased with increasing C/N ratio, and the maximum LA concentration was 468.5 ±44.3 mg COD g-1 VSadded (VSadded means added fermentation material is calculated as volatile solids) at a C/N ratio of 35 at 12 days of digestion. VFAs showed an opposite trend, with a maximum VFA concentration of 601.1 ±42.4 mg COD g-1 VSadded found at a C/N ratio of 12.7 after 12 days of digestion. Potential energy analysis of the highest SCCA production showed that the unit energy value of SCCAs for drop-in fuel production was 50.5% higher than that of methane. Analysis of the microbial community showed that the dominant bacterial groups changed gradually from butyric acid-producing bacteria (Clostridium) to lactic acid-producing bacteria (Lactobacillus) as the C/N ratio increased from 12.7 to 50.2. Keywords: Anaerobic digestion, Corn silage, Lactic acid, Short-chain carboxylic acids, Swine manure.
