Combined effects of LED lights and chicken manure on Neochloris oleoabundans growth

In this study a photobioreactor prototype is presented for the culture growth of microalgae model organism Neochloris oleoabundans by using chicken manure waste as feedstock along with the optimum combination of led light wavelengths and light intensity. Particularly interesting results are observed on the strains fed by chicken manure medium under the proper combination of red and blue LED light illumination, the microalgal growth resulted comparable with the strains fed by the costly commercial microalgal growth medium (BG 11 medium). Cell concentration, optical density, growth rate, cell size, total lipid and photosynthetic pigment content have been monitored during a time-course experiment. The data suggest that there are difficulties due to white light diffusion into the dark chicken medium, which leads to a generally lower intensity scattered along all wavelengths; blue or combined red and blue lights resulted in a higher irradiation density, affecting microalgae cell growth.

A comparative study of adsorption and regeneration with different agricultural wastes as adsorbents for the removal of methylene blue from aqueous solution

Abstract Removal of dye from the industrial wastewater is one of the most important subjects in water pollution regulation. Successive adsorption/desorption cycles of a basic dye, methylene blue, on the internal almond shell, sheep manure waste and sawdust were investigated using fixed bed column experiments in order to study the adsorption capacity to remove MB and adsorbent regeneration efficiency. The adsorption breakthrough curves were predicted by the Thomas model, Yoon Nelson model, and Wolborska model and modified dose–response model using non-linear regression analysis. The results showed that the modified dose–response model was more suitable for the description of breakthrough curves for three adsorbents only in the first cycle. Although sheep manure waste presents the highest adsorption capacity, it is hard to regenerate and needs more time regeneration. Conversely, the internal almond shell presents lower adsorption capacity, but they are more readily regenerated.

Development of combined plant of biogas and bio solid-refuse-fuel from swine manure slurry

An environment-friendly treatment of organic waste like swine manure and food waste is considered to be big challenge, because the residue of organic wastes after anaerobic digestion contains still high amount of undigested organics and is not allowed to dump to ocean by international regulation. The residue from anaerobic digestion of organic wastes, on the other side, has high energy potential because of its leftover organics. In this study a new and integrated treatment process plant of 40 ton swine manure with 20 ton food waste a day has been developed to achieve environment-friendly disposal of swine manure and to produce renewable solid fuel, which has combined two processes of biogas plant and bio solid-refuse-fuel plant. The residue of anaerobic digestion from biogas plant was conveyed to the bio solid-refuse-fuel plant and dried in dryer using the biogas produced in biogas plant as a burner fuel and finally pelletized for a renewable solid fuel. About 30% of total biogas was supplied for 8 h operation of dryer and the leftover 70% was used for generating electricity in the 250 kW gas engine power generator. The produced pellet was analyzed to have good fuel property that meets the Korea Bio Solid-Refuse-Fuel Quality Standard.

Changes in microbial pathogen dynamics during vermicomposting mixture of cow manure\u2013organic solid waste and cow manure\u2013sewage sludge

In two cocomposting cases, the parasite eggs were completely removed in the second week.ConclusionThe results showed vermicomposting as a feasible method to convert waste into fertilizer humus in agriculture which also enables to achieve Iranian class A compost standard.

Productivity Enhancement Using Kinetic Modeling of Bio-digestion Process-A Review

Bio-digesters convert organic waste (agricultural and food waste, animal or human manure, and other organic waste), into energy (in the form of biogas or electricity). An added benefit to bio-digestion is a leftover high-grade organic fertilizer. Models of the Bio digestion process do exist, but either relies on simple algebraic equations instead of biochemical reactions, or considers so many external parameters that they become overly complicated and require much input information and computation time. This work provides the review of features and limitations of different kinetic models of bio digestion process to enhancement on productivity.

Enhancement of Methane Concentration by Removing Contaminants from Biogas Mixtures Using Combined Method of Absorption and Adsorption

We report a laboratory scale combined absorption and adsorption chemical process to remove contaminants from anaerobically produced biogas using cafeteria (food), vegetable, fruit, and cattle manure wastes. Iron oxide (Fe2O3), zero valent iron (Feo), and iron chloride (FeCl2) react with hydrogen sulfide (H2S) to deposit colloidal sulfur. Silica gel, sodium sulfate (Na2SO4), and calcium oxide (CaO) reduce the water vapour (H2O) and carbon dioxide (CO2). It is possible to upgrade methane (CH4) above 95% in biogas using chemical or physical absorption or adsorption process. The removal efficiency of CO2, H2S, and H2O depends on the mass of removing agent and system pH. The results showed that Ca(OH)2solutions are capable of reducing CO2below 6%. The H2S concentration was reduced to 89%, 90%, 86%, 85%, and 96% for treating with 10 g of FeCl2,Feo(with pH), Fe2O3,Feo, and activated carbon, respectively. The H2O concentration was reduced to 0.2%, 0.7%, 0.2%, 0.2%, and 0.3% for treating raw biogas with 10 g of silica gel and Na2SO4for runs R1, R2, R3, R4, and R5, respectively. Thus, given the successful contaminant elimination, the combined absorption and adsorption process is a feasible system for biogas purification.

Energy Resources for Peace and Comfort in Underdeveloped Regions: Design of a Micro Biogas Plant for Small Farms

Sound politics and a robust economy are essential ingredients for peace in human society. Most of the advanced countries in the world have both, and they could have sustained a peaceful atmosphere even after the 2nd World War. With the first and second Industrial Revolution, advances in science and technology development have brought economic fruitfulness and social wealth. The underdeveloped countries also need all of these things, which the advanced nations have already enjoyed over the last 200 years. For a peaceful society, these countries need at minimumto achieve food security, as well asa dependable energy sourcein order to sustain day-to-day life. The stable supply of agricultural products should be accomplished first, and a recycling system between production and regeneration of all the bio-waste would be necessary and worthy for achieving agricultural independence. All the bio-waste can be converted to the biogas by way of the fermentation process. In many developing countries, small farming is conventional,so an effective recycling and environmental protection infrastructure is perceived as very demanding. Biogas, however, can be used as a fuel; and its residues, following fermentation process, can be produced as an organic fertilizer for optimum agricultural development. Biogas in rural areas can also be used for heating, cooking or light. This organic fertilizer can significantly reduce the production cost of vegetables and crop harvesting. For agricultural purposes, it is crucial that organic fertilizer be suitable to increase the fertility of soil. To establish social equalities, microeconomic businesses have been suggested and implemented so far. Herewith we can support further development of ideas, which comprise seven benefits: local energy (i.e. biogas from swine manure) fertilizer ready to use (residues from the biogas process), local reduction of pollution (conversion of animal manure into energy in the confinement of a small plant),reduction of health risks (safer handling of manure) and the micro business option to sell biogas in a backpack, as well asthe reduced need to collect firewood, and the possibility to increase the number of cattle and pigs by dealing with the problem of manure waste. Micro biogas plants made from scrap building materials can make this enterprise possible.

The Effect of Severe Drought on the Evolution of Urban and Manure Wastes in an Agricultural Soil in Mediterranean Ecosystems

AbstractIn semi‐arid Mediterranean soils, water availability is the most limiting factor, negatively affecting the organic matter (OM) degradation. The aim of this work is to study under controlled laboratory conditions how three sources of OM [municipal solid waste (MSW), sheep manure (SM) and cow manure (CM)] behave when they are applied to an agricultural soil subjected to a severe year‐long drought. In order to apply the same concentration of OM to the soil (16·92 Mg OM ha−1), 2 kg of soil was mixed with 30, 67·41 and 55·25 Mg ha−1 (dry matter) of MSW, CM and SM, respectively. Two levels of irrigation were employed: (i) watered soils and (ii) non‐watered soils. Soil's chemical properties [water soluble carbon (WSC), humic acids, fulvic acids and protein mass distribution], biological properties (soil microbial biomass carbon and o‐diphenoloxidase activity) and solid‐state 13C cross‐polarisation magic angle spinning nuclear magnetic resonance spectroscopy were determined. In watered soils, the soil microbial biomass carbon was higher in the SM than in CM and MSW treatments (9·9% and 23·1%, respectively). The WSC was significantly higher in SM than in CM (55·7%) and MSW (78·7%) treatments. A decrease in the content of O‐alkyl C and an increase in alkyl C, aromatic C and carboxyl C were observed. In non‐watered soils, the biochemical properties and alkyl C and alkyl/O‐alkyl ratio decreased, whereas WSC content and O‐alkyl C increased. These results indicated that the evolution of OM and the activity of the microbial community in non‐watered soils were very different to those in the watered soils.

EXPERIMENTAL LABORATORY RESEARCH AND EVALUATION OF PERIODIC OPERATION SMALL SIZE BIOREACTORS / PERIODINIO VEIKIMO MAŽŲ MATMENŲ BIOREAKTORIŲ LABORATORINIAI EKSPERIMENTINIAI TYRIMAI IR VERTINIMAS

The investigation device – small size periodic operation bioreactors, which are developed for the production of biogas from different organic, vegetable waste. The device operates by maintaining optimum operating temperature and oxygen concentration required for anaerobic treatment process inside the bioreactor. Under favorable conditions, organic substance is being degradated because of anaerobic processess, colonies of microorganisms grow, and methane bacteria produce CH4 – useful flammable gases, which can be used as natural gas analogue. The gas is stored in special tanks of gas – gas holders. A study was implemented by analizing five different loads, according to the mixing ratio of vegetables (potatoes) and chicken manure waste. The quality and quantity of biogas was analized as well. It was found that the highest concentration of methane (67.8%) was achieved by using a load consisting only of chicken manure, but after evaluation of biogas yield, it was found that the best result (according to the quantity of biogas, a high concentration of CH4 and time of load degradation) is achieved using chicken manure and potato waste mix (relatively 70 and 30%). Mesophilic process temperature during the experiment was 33–35 °C, and oxygen concentration – 0.0–0.1%. After research implementation there will be an opportunity to create small size periodic operation bioreactors, which can be used in small farms or private houses, where the small amount of organic waste and manure are formed. Nagrinėjamas įrenginys – mažų matmenų periodinio veikimo bioreaktorių laboratorinis stendas, skirtas biodujų gamybai iš skirtingų organinės, augalinės kilmės atliekų. Stendas veikia palaikant optimalų temperatūrinį režimą ir anaerobiniam procesui reikalingą deguonies koncentraciją bioreaktorių viduje. Esant palankioms sąlygoms, vyksta įkrovos organinių medžiagų anaerobinės degradacijos procesai, auga mikroorganizmų kolonijos, ir metanogeninės bakterijos, kurios yra priskiriamos prie labai jautrių anaerobų, gamina metaną CH4 – energijos atžvilgiu naudingas degias dujas, kurias galima panaudoti kaip gamtinių dujų analogą. Biodujos yra saugomos specialiose dujų talpyklose (angl. gas holders). Atliktuose tyrimuose buvo nagrinėjamos penkios skirtingos pagal sumaišymo santykį daržovių (bulvių) atliekų ir vištų mėšlo įkrovos, biodujų sudėtis ir jų kiekis. Nustatyta, kad didžiausia metano koncentracija (67,8 % buvo pasiekta naudojant įkrovą, sudarytą tik iš vištų mėšlo, tačiau įvertinus biodujų išeigą nustatyta, kad geriausias rezultatas (pagal biodujų kiekį, aukštą CH4 koncentraciją ir įkrovos skaidymo laiką) pasiekiamas naudojant vištų mėšlo ir bulvių atliekų įkrovų mišinį (sumaišymas atitinkamai 70 ir 30 %). Mezofilinio proceso temperatūra eksperimentų metu siekė 33–35 oC, o deguonies koncentracija – 0,0–0,1 %. Laboratorinių eksperimentinių tyrimų pagrindu galima sukurti mažų matmenų periodinio veikimo bioreaktorius, kuriuos būtų įmanoma panaudoti nedideliame ūkyje arba privačiuose namuose, kur susidaro santykinai maži kiekiai mėšlo ir maisto atliekų.

Properties of vermicompost aqueous extracts prepared under different conditions

ABSTRACTThe aim of this work was to determine the influence of aeration and time of extraction on the agrochemical properties of aqueous extracts from vermicomposts made from horse manure (M) and apple pomace (P) waste. There were two extract treatments: stirring without aeration (S), and stirring with aeration (A) for 48 h. Aeration significantly increased the levels of electrical conductivity (EC) and the concentration of , , and macro-elements in the extracts. In the (A) treatment, the extraction efficiency of K and Mg increased twofold, and the extraction efficiency of Ca and P increased by one-third compared with the (S) treatment. Simultaneously, the extracts prepared under aeration were characteristic with a higher pH value compared with non-aerated variants. The EC and content of macro-elements in the extracts increased proportionally with time. Their highest growth was found within the first 6 h. After 48 h, the highest release of macro-elements into the extract was found in the case of the horse manure under stirring with aeration.

Utilizing Composted Beef Cattle Manure and Slaughterhouse Waste as Nitrogen and Phosphorus Fertilizers for Calcareous Soil

ABSTRACTEffectively utilizing composts requires that their nitrogen (N) and phosphorus (P) contents be used as fertilizer, but how this is best accomplished is not fully understood. The authors' objective was to quantify N and P availability of a calcareous clay loam soil receiving composts derived from four contrasting beef cattle feedlot feedstocks applied at 50, 150, and 450 mg total P kg−1 and supplemented twice with fertilizer N for a 42-week greenhouse plant bioassay. Three composted manures from beef cattle fed distinct diets and a composted mix of slaughterhouse and construction waste were applied. Inorganically fertilized and non-amended soils were included as controls. Canola (Brassica napus L.) and pea (Pisum sativum L.) were grown in pots containing 1.5 kg air-dried soil for six alternating 7-week cycles. Soils amended with composted manure from beef cattle fed typical finishing diets had the lowest apparent N recovery (31%) and the greatest soil nitrate after 42 weeks (25 mg N kg−1). Phosphorus availability was greater with composted manure from beef cattle fed distillers' dried grains than composted manure from beef cattle fed typical finishing diets and a composted mixture of slaughterhouse and construction waste. Apparent P recovery (66%) was greatest from composted manure of beef cattle fed corn (Zea mays L.) distillers' dried grains applied at 50 mg total P kg−1. Composted manure from beef cattle fed distillers' dried grains had greater P availability than conventional composted beef cattle feedlot manure. Overall, performance of the composted mixture of slaughterhouse and construction waste was similar to the composted beef cattle manures.

Modelling anaerobic digestion in an industrial biogas digester: Application of lactate-including ADM1 model (Part II)

ABSTRACTA modified Anaerobic Digestion Model No. 1 (ADM1xp) including lactate was applied to a full-scale biogas plant. This model considers monosaccharides to degrade through lactic acid, which further degrades majorly into acetate followed by propionate and butyrate. Experimental data were derived from the previous works in the same laboratory, and the proposed parameters were validated against batch experiments. After successful validation, the biogas plant bearing a fermenter size of 7 dam3 and operated with food waste and cattle manure was simulated. The biogas production and methane content were reliably simulated, and a good fit could be obtained against the experimental data with an average difference of less than 1%. When compared to the original ADM1 model, the performance of the lactate-incorporated model was found to be improved. Inclusion of lactate as a parameter in the ADM1xp model is recommended for an increased sensitivity and enhanced prediction principally for systems dealing with high carbohydrate and lactate loads.

Waste to Electricity Generation in Thailand: Technology, Policy, Generation Cost, and Incentives of Investment

Waste-to-Energy is a challenging management in developing countries. There are many different technologies to generate electricity or heat from wastes. However, reuse and recycling are first prioritized as left a fraction of waste can be used as energy recovery. The initial cost to generate electricity from solid waste incineration is prohibitively high due to its cost of advance technology and the cost of equipment to control emissions. Thailand is agricultural based country and has experiences of many technologies to utilize waste to energy. Landfill gas and thermal gasification are increasingly interesting alternatives to municipal solid waste incineration and it is recommended that biogas technology is suitable and is cost effective in management of organic waste or animal manure waste. This research studied in existing technologies in terms of electricity generated from waste, long term government policy, carbon dioxide reduction, electricity cost production and incentive investment. Until recently, Thailand has generated electricity from waste of 47 MW, from the target in 2021 with target capacity of 400 MW. Since Thailand has an incentive investment of electric power generated from renewable sources and wastes in terms of feed-in tariffs it can motivate private investors to invest and produce electricity to the grid. To generate electricity from waste it also has potential in reducing CO 2 reduction and creates more potential jobs. In various agricultural based industries such as palm oil industry, cassava industry, in animal farm and in landfills gas have potential to generate electricity in Thailand. In case of landfill gas with the installed capacity of 3.0 MW, it can generate electricity of 13,492 MWh per year and produce potential of selling carbon credits of 60,532 ton-CO 2 per year.

Influence of pig manure and its biochar on soil CO2 emissions and soil enzymes

Biochar production from manure wastes, including pig manure, could provide a valuable alternative to current waste management practices, while offering an opportunity to improve soil properties and to reduce the risk of contamination derived from the direct application of manure as a soil amendment. Two different biochar samples, produced from pig manure at 300°C (BPC300) and 500°C (BPC500) were used to evaluate the impact of biochar amendment on soil enzymatic activity and soil CO2 emissions. An incubation experiment was designed as follows: selected soil (S) was amended with pig manure (PC) and two pig manure biochars prepared at 300°C (BPC300) and 500°C (BPC500) at a rate of 8wt%. All samples were incubated during 219 days.The results indicated that soil amendment with biochars decreased the carbon mineralization, in contrast to soil amended with the pig manure. Addition of pig manure increased dehydrogenase, phosphomonoesterase and phosphodiesterase activities, while B prepared at 300°C resulted on a positive effect on dehydrogenase activity. In contrast, B prepared at 500°C did not exhibit a positive effect on soil enzyme activity.

Households' willingness to accept compensation for agricultural waste recycling: taking biogas production from livestock manure waste in Hubei, P. R. China as an example

The problem of agricultural waste pollution has aroused wide concern around the world. An effective measure to solve this problem is to implement the compensation policy so as to encourage people to participate in agricultural waste recycling. This paper seeks to estimate households' willingness to accept compensation in terms of agricultural waste recycling adopting the contingent valuation method, and to calculate the compensation standard for households' participation in agricultural waste recycling by methods of non-parametric and parametric estimate. It aims to answer two questions: how much the compensation should be given for encouraging households to participate in agricultural waste recycling? Which factors would affect willingness to accept compensation value of households for participating in agricultural waste recycling? The results show that most households recognize the value of agricultural waste recycling and a certain amount of compensation which is about 1.08%–1.31% of average family annual income does encourage households to participate in agricultural waste recycling. Household's willingness to accept compensation and household's expected value of compensation are affected by personal or family characteristics (such as gender, household income) as well as the non-economic variables (such as environmental knowledge and environmental attitude). According to this research, reasonable compensation standard is the cornerstone of the effectiveness and efficiency of compensation policies. Household income inequality and capital allocation in terms of households' willingness to accept compensation should be taken into consideration when compensation policies about agricultural waste recycling are formulated. Environmental education for households is an effective measure to enhance their environmental consciousness, while raising the strength of government's waste management is turned out to be effective for improving the rural ecological environment. Conclusions of this study provide an important scientific basis for developing countries and regions to formulate compensation policies in terms of inspiring their agricultural waste recycling.

The Occurrence of Veterinary Pharmaceuticals in the Environment: A Review.

It is well known that there is a widespread use of veterinary pharmaceuticals and consequent release into different ecosystems such as freshwater bodies and groundwater systems. Furthermore, the use of organic fertilizers produced from animal waste manure has been also responsible for the occurrence of veterinary pharmaceuticals in agricultural soils. This article is a review of different studies focused on the detection and quantification of such compounds in environmental compartments using different analytical techniques. Furthermore, this paper reports the main challenges regarding veterinary pharmaceuticals in terms of analytical methods, detection/quantification of parent compounds and metabolites, and risks/toxicity to human health and aquatic ecosystems. Based on the existing literature, it is clear that only limited data is available regarding veterinary compounds and there are still considerable gaps to be bridged in order to remediate existing problems and prevent future ones. In terms of analytical methods, there are still considerable challenges to overcome considering the large number of existing compounds and respective metabolites. A number of studies highlight the lack of attention given to the detection and quantification of transformation products and metabolites. Furthermore more attention needs to be given in relation to the toxic effects and potential risks that veterinary compounds pose to environmental and human health. To conclude, the more research investigations focused on these subjects take place in the near future, more rapidly we will get a better understanding about the behavior of these compounds and the real risks they pose to aquatic and terrestrial environments and how to properly tackle them.

The Effects of Different Organic Wastes on Mineral Element Content in Organic Strawberry Cultivation

ABSTRACTIn this article, five different organic waste effects on mineral uptake in growing organic strawberries was investigated. In the experiment, the impacts of different organic wastes, such as hazelnut husk (H), hazelnut husk compost (HC), rice hull (R), rice hull compost (RC), and farmyard manure on mineral element contents of strawberry cultivars ‘Camarosa’ and ‘Sweet Charlie’ were investigated. The harvesting of the plants was performed at the beginning of resting, fluorescence, and at the end of the harvest throughout the experiment in order to examine the impacts of organic wastes on mineral element contents, which were detected in the leaf samples extracted from these harvests. In this experiment, it was observed that the applications H Compost and H yielded better results than farmyard manure and other wastes regarding mineral element content. In the research, when examined pull up dates, N, P, Mg, Fe, and Mn contents were adequate, but K, Ca, and Zn contents were found to be insufficient in strawberry leaves.
