Effect of Different Feeding Materials on the Trace and Nutrient Elements of Vermicompost using Eisenia fetida

The aim of this study was to determine the influences of different feeding materials on the physico-chemical parameters of vermicompost using Eisenia fetida. In this study, four treatments, with the same conditions in terms of organic wastes type were prepared to produce vermicompost from hazelnut husk (% 100), tea plant waste (%100), hazelnut husk (A) (% 50) + tea plant waste (B) (50%), hazelnut husk (A) (30%) + tea plant waste (30%) + cow dung (20%) + sawdust (15%) + waste newspaper (%5) using earthworms. The standard laboratory analysis methods were used to determine the physical and chemical parameters in the different produced vermicomposts. The mean N content in the growing medium A, B, C, and D was 1,41%, 2,5%, 1,96%, and 1,47% respectively. The mean phosphorus content in the growing medium A, B, C, and D was 807,69 mg/kg, 1748,25 mg/kg, 1491,25 mg/kg, and 1410,75 mg/kg respectively. The mean potassium in the growing medium A, B, C, and D was 11244,69 mg/kg, 7790 mg/kg, 6884,25 mg/kg, and 8006,25 mg/kg respectively. Compared to the initial vermibed mixture, the N, P, and K content was higher in all the growing mediums. The Pb, Cd and As content was lower in all the growing mediums in the final compost than the initial vermibed mixture. Eisenia fetida is very effective in converting some waste materials into high-quality compost and decreasing the heavy metal content in the final vermicompost more than in the initial vermibed mixture.

Optimization of hazelnut husk medium for pullulan production by a domestic A. pullulans strain

Hazelnut husk is one of the most abundant agricultural residue in Turkey. Valorization of this lignocellulosic biomass would provide a promoting alternative for economical production of pullulan. In this study, dried hazelnut husk hydrolysate was used directly as fermentation medium for pullulan production by a domestic strain of Aureobasidium pullulans. The aim of this work was the optimization of some fermentation medium parameters by central composite design using response surface methodology (RSM). The effects of (NH4)2SO4 concentration, the volume of concentrated H2SO4 and the amount of ground hazelnut husk on pullulan production were optimized by RSM. The optimum levels of the fermentation parameters defined as 7.2 gL−1, 2.5 mL and 20 g, respectively. The maximum pullulan and exopolysaccharide concentrations were determined as 74.39 and 75.95 gL−1 , respectively in the optimum conditions. Specific growth rate of the strain was found as 0.097 h−1. FTIR spectral attributes confirmed the structure of pullulan. Thermal decomposition temperature of synthesized pullulan was found as 247.15 °C. This study showed that hazelnut husk was one of the novel substrate for production of the pullulan by A. pullulans AZ-6. No previous work was found to utilize dried hazelnut husk as fermentation medium for pullulan production by A. pullulans.

Effect of different organic wastes on biological properties of maize (Zea Mays Indendata) rhizosphere

This study was carried in order to determine the effects different various organic wastes (tobacco prodction waste, wheat straw, tea waste and hazelnut husk) under greenhause conditions on biological properties (microbial biomass C, basal soil respiration, dehydrogenase activity, urease activity and arlysulphatase activity) in clay-loam soil and rhizosphere (Zea mays indandata) soil of maize plant. The organic wastes were thoroughly mixed with the soil at a rate equivalent to 50 g kg-1 on air-dried weight basis. Experimental desing was randomized plot desing with there replications in greenhause. The moisture content in soil was mantained around 60 % of maximum water holding capacity by weighing the pots everday. Changes in the biological properties were determined in the soil and rhizosphere (Zea mays indendata) samples and root free soil taken in 15, 30, 45, 60, 75 and 90 days after the experiment was conducted. At the end of experiment, all organic waste added soil increased biological properties of soil in comparison with the control (P<0.01) at all experimental periods. Moreover, biological properties in rhizosphere soil were higher than in root free soil at all organic waste application (P<0.01). Increased of organic wastes on soil biological properties had different trend (P<0.01), the most increases in the biological properties in the soil treated with tea wastes and tobacco production waste with supplying of low initial C/N ratio compared to other organic wastes.

A rapid and precise method for determining water content in nuts as a tool for determining their quality during storage

This study was designed to examine impact of storage conditions on hazelnut quality and to develop a quick method for testing hazelnut moisture. The change of sample mass and water content were assessed by convection drying method and by means of a moisture analyzer—IR radiation. The samples were tested as: nuts, nut kernels, crumbled nut kernels, husk of nuts. They were stored in closed and open packages at 45% and 80% humidity and at constant temperature (23 °C). It has been observed that at the humidity of 45%, the hermetic packaging reduced hazelnut mass loss by 18%, and the hazelnut husk caused reduction of mass loss of the kernel by 5.5%. It was found that the best storage effects were obtained at a relative air humidity of 80% (i.e. change in hazelnut weight 2.18%, kernels 0.78%, shell 1.4%). At this moisture content, in comparison with the moisture content equal to 45%, a lower loss of hazelnut weight by 4.65%, kernel weight by 10.79%, shell weight by more than two times was found when the samples were stored without packaging. Water desorption from hazelnut stored under these conditions was reduced to 0.4% for packaged kernels and to 3% for unpackaged product. Determining the water content by the IR radiation method, compared to the standard method, took much less time, it took about 1 h. 5 min (approx. 6 times faster) with a measurement accuracy of 0.26%. Therefore this paper proves that the described method positively influences time restrictions especially when the duration of water content analysis is a key determinant. According to the authors, it can be implemented in both laboratory and industrial tests, saving time and acting immediately when the technological process requires support.

Evaluation of Some Agro-Industrial Wastes as Fermentation Medium for Pullulan Production by Aureobasidium pullulans AZ-6.

Agro-industrial wastes are rich sources of some nutrients. Thus, utilization of wastes seems to be ecologically sound and economically advantageous. The aim of this work was to investigate the potential usage of various agro-industrial wastes as fermentation medium for pullulan production by a domestic strain; Aureobasidium pullulans AZ-6. In this study, different agro-industrial wastes; various citrus peels, grape pomace, the hydrolysates of hazelnut and chestnut shells, sugarcane molasses residue, dried and fresh hazelnut husks and pumpkin peel, were used as fermentation media without adding any extra nutritional component for pullulan production by A. pullulans AZ-6. As a result, among the tested media, the maximum pullulan concentration was obtained as 33.59 gL-1 using the sugarcane molasses residue, and followed by the corresponding value of 30.02 gL-1 obtained in the dried hazelnut husk hydrolysate medium. Therefore, the usage of agro-industrial wastes as fermentation media is considered to make pullulan production cost effective. In addition, waste treatment from this aspect solves a relevant environmental problem. In this study, sugarcane molasses residue and dried hazelnut husk hydrolysate were used directly as fermentation media for pullulan production for the first time. Pullulan production from sugarcane molasses residue and dried hazelnut husk hydrolysate media might be a promising substrate for economical point of view.

Spectroscopic Characterisation and Elemental Composition of Biochars Obtained from Different Agricultural Wastes

The use of biochar (BC) has an environmental importance in terms of climate change, soil fertility, waste management and energy generation. The purpose of this study was to reveal some of the structural characteristics of BC produced from agricultural wastes by employing spectroscopic techniques within a short time frame. The BCs were produced via slow pyrolysis at 300 °C from four feedstocks: tea waste (TW), hazelnut husk (HH), rice husk (RH) and poultry litter (PL). The pH of plant-derived BC was alkaline (pH: 7-9), and the pH of manure-derived BC was strongly alkaline (pH: 10.1). PLBC has the highest (4.67 dS m-1) electrical conductivity (EC) when compared to other BC materials. According to the X-ray fluorescence (XRF) analysis method, organic compound contents of TWBC and HSBC were found to be higher than the other two BCs, while the other two BCs (RHBC and PLBC) were richer in mineral content. TWBC and HHBC were composed of more mineral elements when compared to RHBC and PLBC, but the latter two were still rich in minerals. The surface area of RHBC was found higher (12.9 m2 g-1) than other BC materials. According to the X-ray fluorescence (XRF) analysis method, the total element content of PLBC was found higher than the other BCs. In addition, the silicon (Si) content of RHBC was considerably higher (16.4%). In PLBC’s XRD diagram: quartz (SiO2) at 3.41 (Å); calcite (CaCO3) at 3.96, 2.94 and 1.91 (Å); sylvine (KCl) at 3.06 and 1.85 (Å); and whitlockite ([Ca, Mg]3 [PO4]2) at 2.78 and 2.17 (Å) were found. In HHBC and RHBC diagrams, partially crystallized carbon (CryC) peaks were mainly observed between 1.20 and 2.34 (Å), and cristobalite peaks (i.e., amorphous SiO2) were observed at 3.91 and 3.40 (Å).

Production of chemically and microwave activated hazelnut husk as an adsorbent for dye contaminated wastewaters

Adsorption has traditionally been evaluated as an economical and easily applicable process for treating certain wastewaters, such as ones including dyes and heavy metals. Even though adsorbent materials specifically produced for the purpose of wastewater treatment commercially exist, the production cost may create an economic burden on wastewater treatment processes. Agricultural wastes can be valorized as adsorbents in adsorption processes. The adsorption capacity of these wastes can be improved via pre-treatment methods such as chemical application and microwave irradiation. This study investigated the potential applicability of hazelnut husk as an adsorbent for methylene blue (MB) dye. To this purpose, the husk was activated by sequential chemical or water and microwave applications. Structural analysis on the produced adsorbent was performed by Fourier transform infrared spectrophotometry (FTIR) and field emission scanning electron microscopy (FE-SEM). Isotherm (Langmuir, Freundlich, Temkin and Harkins-Jura isotherms) and kinetic (pseudo-first-order, pseudo-second-order, Elovich and intraparticle diffusion kinetic models) behaviours of adsorption were also evaluated. The results indicated that MB could be removed by 92-94% considering all adsorbents produced. Further isotherm and kinetic studies revealed that MB adsorption was both physically and chemically induced, and the reaction followed the pseudo-second-order kinetic model (R2>0.99).

The Effect of Organic Waste and Synthetic Conditioner Applications on Consistency Limits

This study was carried out to determine the effects of wheat straw (WS), hazelnut husk (HH), humic acid (HA) and polyacrylamide (PAM) treatments on consistency limits (liquid limit (LL), plastic limit (PL), plasticity index (PI)) in two soils with sandy loam and clayey loam in texture. Soil samples used in the study were taken from two different areas of land (0-20 cm) from Samsun province's Bafra district. WS (0, 2%, 4%), HH (0, 2%, 4%), HA (0, 200 and 1000 ppm) and PAM (0, 30 and 90 ppm) were used in this study that was conducted in a split plots experimental design with three replications. According to the results; it was determined that the liquid limit, plastic limit and plasticity index values increased with the application of organic and synthetic conditioners in both soil texture, and the effect was realized as WS>HH>HA>PAM. It was observed that the highest dose application was the more effective in both soil texture, except for PAM.

Mechanical and thermal properties of biocomposite films produced from hazelnut husk and polylactic acid

ABSTRACT This study focused on the potential use of hazelnut husk (HH) flour, agricultural by-product, as filler in the PLA biocomposite films. The tensile strength and elongation at break of the biocomposites films decreased with the increasing content of the HH flour. As the amount of the HH flour in the PLA was increased by 10 wt%, the tensile strength decreased from 33 to 26.3 MPa. A sharp decrease in the tensile strength (6.33 MPa) of the specimens was determined as the amount of the HH flour was increased by 20 wt%. There was no significant difference in the tensile strength as the HH content increased from 20 to 40 wt%. The main reason for the lower tensile strength was mainly attributed to them due to the weak interfacial bond between HH flour with higher polar surface and the PLA with lower polar surface. The hydrophilic nature of the HH leads to a tendency for HH fibers to mingle or form agglomerations, which resulted in the lower tensile strength, especially at high HH filler loadings. The increase in the filler content improved the thermal stability of biocomposites.

Effect of Using Urea Formaldehyde Modified with Extracts in Plywood on Formaldehyde Emission

Formaldehyde-based adhesives are used in the forestry industry. This is because formaldehyde is inexpensive, easy to use and resistant to moisture; it also has particular mechanical effects. Formaldehyde has both advantages and disadvantages. It is known that various diseases such as lung cancer occur in humans as a result of the release of formaldehyde into the air during and after board production. In this study, a urea formaldehyde glue mixture was prepared by using four different fillers (extract of maritime pine (Pinus pinaster) and elm (Ulmus glabra) bark, extract of hazelnut (Corylus avellana) husk and acorn tannins) at two different ratios. The bonding shear strength of pine (Pinus sylvestris) and spruce (Picea orientalis) plywood produced with urea formaldehyde adhesive was tested according to EN 314-1 standard. All plywood, except the plywood with acorn tannin, met the requirements of the standard. A formaldehyde emission test of the plywood was carried out in accordance with EN 713-3 standard. With this approach, it is possible to quickly determine formaldehyde emissions. Experimental results were obtained for subsequent measurements, including chamber tests. It was observed that the elm bark extract reduced the formaldehyde emission of pine plywood by 40 %, while other fillers reduced it by 3-37 %.

Stomatal traits of maize grown by applying waste to soils under water stress conditions

Purpose: Drought will be one of the most important questions in the future. The easiest and natural way to drought recovery is to popularize the use of materials that will increase the water holding capacity of soils. The aim of this study is to determine the effect of hazelnut husk applying in water stress conditions on stomatal traits and the growth of maize.Materials and Methods: A greenhouse experiment was conducted in a randomized plot design using three factors:hazelnut husk doses (30-60-80 t ha-1) and three water stress levels (at 75%, 50% and 25% of field capacity); and two different soil texture (clay loam and sandy loam) with three replications.Results: Root fresh weight, total biomass and root:shoot ratio increased by 73%, 51% and 39% respectively when plants grown in clay loam soil are compared with sandy loam soil. Hazelnut husk applications affected both plant growth and stomatal traits, the most effective dose was 80 t ha-1 but the dose of 60 t ha-1 was found sufficient for the stomatal traits. Water stress caused a significant decrease in shoot growth (16-52%), leaf area (13-44%) and stomatal traits whereas irrigation at 50% of field capacity with 60 t ha-1 of the husk was found sufficient.Conclusion: It is thought that other morphological features are also not affected because hazelnut husk prevents the roots from being affected by stress. However, further studies are needed to determine the effects under field conditions.

Effective Copper and Methylene blue adsorption from industrial effluents onto activated carbons prepared from Rice husk ash and Hazelnut husks modified by Diopside: Equilibrium, Kinetics, and Experimental design

ABSTRACT Activated carbon from rice husk ash (AC-RH) and hazelnut husks (AC-HH) modified by Diopside (AC-RH/Diop, AC-HH/Diop) composites were synthesised and applied for the adsorption of Copper and Methylene blue from industrial effluents. Diopside was provided by the sol-gel method and activated carbon was prepared from rice husk ash and hazelnut husks. The formation of AC/Diop composites was characterised by FT-IR, FESEM, BET, and XRD analyses. Effects of pH, amount of adsorbent, and contact time at 10 mg L−1 of Copper and Methylene blue on removal percentage were studied by Box Behnken design (BBD). Optimal conditions for maximum Copper and MB by AC/Diop adsorbent (95.54% and 99.42%, respectively) were as follows: (pH = 5.45, 7.35) (adsorbent amount: 0.10, 0.45 g), and (contact time: 9.56, 13.49 min) in 20 mL of 10 mg L−1 of pollutants concentration, respectively. In addition, the adsorption kinetics, thermodynamics, and isotherms were examined. Adsorption isotherms (qmax: 184.25 and 289.51 mg g−1 for Copper and MB, respectively) and kinetics were demonstrated that the sorption processes were better described by the Langmuir and pseudo-second-order equation.

Investigation of Hazelnut Husk Combustion by using A Novel Non-linear Kinetic Model through Thermogravimetric Analysis

Considering economic and environmental issues, boosting renewable energy source is the main subject to fulfill energy demand in these days. Biomass as natural and abundant energy source can be typically used to produce electricity, fuels and heat applying thermochemical conversion processes such as combustion, pyrolysis or gasification. Biomass combustion is the most common process to produce electricity and useful heat in Turkey and all over the world. The aim of this study is to investigate the considerable influence of heating rates on combustion characteristics and kinetics employing a new developed non-linear kinetic model for hazelnut husk samples through thermogravimetric analysis. Furthermore, this work comprehensively assesses the variations in the reactivity of hazelnut husk combustion, expressed from thermogravimetric curves. The non-linear kinetic model developed in this study integrates the various kinetic pathway to estimate the major controlling parameter of combustion reactivity, its activation energy, pre-exponential factor and reaction order. According to comparison of results from the non-linear kinetic model for volatile combustion and fixed carbon combustion, correlation coefficients (R2) for both models are higher than 0.9985. These results proved the non-linear regression model for kinetic pathways in combustion reactivity worked properly to estimate thermal decomposition behavior.

Utilization of various lignocellulosic substrates for Pleurotus ostreatus mushroom cultivation in the manufacturing of polycaprolactone (PCL)-based biocomposite films

The possibility of using beech wood sawdust and hazelnut husk waste generated during the cultivation of Pleurotus ostreatus mushrooms as a filler in polycaprolactone (PCL)-based biocomposite films was investigated. Chemical and physical properties of the PCL biocomposites were determined. The beech sawdust and hazelnut husk were exposed to degradation for 73 d and 78 d, respectively, in slightly acidic environments at a relative humidity of 75%. The degraded materials caused the holocellulose and lignin contents in the PCL biocomposites to decrease, while the cellulose and α-cellulose contents increased. In general, as the lignocellulosic waste content increased, the tensile strength (TS) and elongation at break (EatB) values decreased and the tensile modulus (TM) and water absorption (WA) values increased. It was determined that the PCL biocomposite with the degraded beech sawdust absorbed more water than the composite with the undegraded beech sawdust. On the other hand, the PCL biocomposite with the degraded hazelnut husk absorbed less water than the composite with the raw hazelnut husk.

Vermicomposting of anaerobically digested sewage sludge with hazelnut husk and cow manure by earthworm Eisenia foetida

Vermicomposting of organic waste has an important part to play in an integrated waste management strategy. The aim of the present study was to investigate the ability of an epigeic earthworm Eisenia foetida to transform anaerobically digested sewage sludge (SS) amended with hazelnut husk (HH) and cow manure (CM) in different proportions under laboratory condition (in darkness at 25°C0,5 0C). Two approaches investigated in the study were: (1) to find the best medium for growth and reproduction of E. foetida in different feed mixtures, (2) to analyze the heavy metal concentrations in different feed mixtures of SS-HH-CM before and after vermicomposting, and (3) to explore heavy metals accumulation of earthworms in sewage sludge with different feed mixtures. Number and biomass of earthworms and heavy metal contents in feed mixtures and earthworms were periodically monitored. The results indicated that maximum earthworm biomass was attained in feed mixture of 20% SS + 40% CM + 40% HH while the earthworm number was highest in feed mixture of 30% SS + 35% CM + 35% HH during the vermicomposting period. Heavy metals concentration (Zn, Cu, Cd, Pb, Ni and Cr) in all feed mixtures decreased associated with the increasing vermicomposting time. The heavy metals’ content in the feed mixtures was lower than that of initial mixtures. Metal analysis of earthworms revealed considerable bioaccumulation of heavy metals in their bodies’ tissue. Heavy metal analysis of earthworm body showed that increasing proportion of SS in the feed mixtures promoted the heavy metal content of earthworm body.

Characterization and kinetics analysis of the thermal decomposition of the humic substance from hazelnut husk.

A humic substance was obtained from hazelnut husk using an alkali extraction. The chemical and morphological structure of the humic matter was characterized via elemental analysis, Fourier transform infrared spectrometry (FTIR), nuclear magnetic resonance, Brunauer-Emmet-Teller (BET) analysis, scanning electron microscopy (SEM), and thermogravimetric-FTIR (TG-FTIR). In addition, thermal analysis measurements TG analysis-differential thermogravimetry/differential scanning calorimetry (TGA-DTG/DSC) were performed under dynamic air conditions to better determine the origin, physical and chemical structure, and decomposition process of the humic matter. The Kissinger-Akahira-Sunose (KAS) and Flynn-Wall-Ozawa (FWO) methods were used to calculate the kinetic parameters of the high-temperature decomposition process. It was observed that the activation energy values were almost constant at certain conversion and temperature intervals. In addition, the structure of the humic substance at different temperatures was also investigated via FTIR analysis. It was found that the obtained humic substance had a very stable structure and decomposed at a high temperature. The stability of the humic matter can be a useful tool in the environmental quality research of soil.

The Sustainable Use of Cotton, Hazelnut and Ground Peanut Waste in Vegetable Crop Production

The environmental burden from crop production byproducts is gradually increasing and necessitates the sustainable management of waste towards a circular economy approach. In the present study, three byproducts (cotton ginning waste (CGW), ground hazelnut husks (GHH) and ground peanut husks (GPH)) were evaluated in lettuce cultivation. For this purpose, the tested materials were incorporated in soil at two different rates (25% and 50% of total substrate volume) while a control treatment (no addition of byproducts) was also considered. Fresh weight per plant and total yield was the highest for the GHH50% treatment. The highest fat, protein, carbohydrates and energy content were observed for the CGW25% treatment. Chemical composition also differed among the tested byproducts where CGW25% treatment had the highest total tocopherols, sugars (sucrose, fructose, trehalose and total sugars) and organic acids content. The most abundant fatty acids were α-linolenic, linoleic and palmitic acid in all the tested treatments, while the highest antioxidant activity was observed for the GHH50% treatment. Regarding polyphenols, phenolic acids content was the highest in the GHH treatments, whereas flavonoids were the highest for the CGW25% treatment. No cytotoxicity against the PLP2 non-tumor cell line was observed, whereas only the GPH50% treatment showed moderate efficacy against HeLa, HepG2 and MCF-7 cell lines. The tested extracts also showed moderate antibacterial activities and only the extracts from the CGW50% treatment were more effective than the positive control against Trichoderma viride. In conclusion, the present results showed the great potential of using the tested byproducts as soil amendments for vegetable crops production, since they may improve the nutritional parameters, the chemical profile and the bioactivities of the final product. The suggested alternative use of the tested byproducts not only will increase the added value of crops but will also alleviate the environmental burden from bulky agroindustry byproducts.
